In the present research, some Bacillus strains were produced at the industrial scale in order to be tested on chickpea growth, under pots and field conditions. Bacteria reached high sporulation yields ranging from 0.8×109-2.5×109 and 8×109-10×109 spores mL-1 in flasks and 500 L bioreactor culture conditions, respectively. Under pots experiment, B. amyloliquefaciens (9SRTS) and B. amyloliquefaciens (CWBI) increased significantly the root mass (0.31 and 0.37 vs. 0.066 g, respectively) and reduced the percentage of discolored leaves per plant (41 and 26 vs. 74%, respectively). Under field conditions, chickpea plants reached 21.59, 23.11, 20.80 cm, after 1 month of growth in lots treated with CWBI; 9SRTS; 6SEL (B. atrophaeus), respectively in comparison to control (17.63 cm). Root dry mass was not affected (p>0.05) and values were between 0.87 and 1.36 g. At harvest, the total number and mass of chickpea grains were higher in lots treated, compared to a control. Importantly, B. amyloliquefaciens (9SRTS) showed the best effect on chickpea crop yield (236 vs. 176 grains; 153 vs. 114 g). These data estimated per hectare reached 7.65 vs. 5.7 q, so, a gain of 2 quintals per ha. [less ▲]

This paper aims at, firstly, highlighting the morpho-biometric characteristics of the Tazegzawth sheep breed, and, secondly, describing the sheep farmers profile and their farming practices. The study was carried out in Kabylie (Algeria) which is the breed cradle of Tazegzawth sheeps. The essay concerned 16 breed farmers located in the Wilayas of Bejaia and Tizi-Ouzou. Each of the 85 sheeps (24 rams and 61 ewes) was characterized and profiled. The study indicated that the sheep farming is a diversification activity and not a specialized activity. Other breeds and species are kept by the farmers. Due to the sharing of grazing areas between farmers, anarchic matings occurred contributing to the Tazegzawth breed’s decline. Farmers involved in this study were male having on average 12.13±3.84 livestock heads per household. All the farmers used local resources as supplement feeding: organic waste, crop leftovers, hay and olive foliage, ash, elm, oak and fig foliage. Average live weight of males (68.48±1.12 kg) were highly significantly higher (p-value <0.01) than the average live weight of females (53.84±1.16 kg). Livestock systems involving Tazegzawth breed showed high diversity. The multiple correspondences analysis indicated 4 groups depending on the time length over which animal breeding took place, the bred animal species, the number of Tazegzawth bred animals, and the aims and objectives of the animal farming.

The effects of early age thermal conditioning (ETC), vinegar supplementation (VS) of drinking water, broilers’ gender, and their interactions on respiratory rate, body temperature, and blood parameters (biochemical, hematological, and thyroid hormones) of broiler chickens reared under high ambient temperatures were determined. A total of 1100 1-day-old chicks were divided into four treatments: the “control” which were non-conditioned and non-supplemented; “heat-conditioned” which were exposed to 38 ± 1 °C for 24 h at 5 days of age; “vinegar supplemented” which were given drinking water supplemented with 0.2% of commercial vinegar from 28 to 49 days of age; and “combined” which were both heat conditioned and vinegar supplemented. All groups were exposed to the natural fluctuations of summer ambient temperature (average diurnal ambient temperature of about 30 ± 1 °C and average relative humidity of 58 ± 5%). ETC and broiler gender did not affect the respiratory rate or body temperature of chronic heat-exposed chickens. VS changed the body temperature across time (d35, d42, d49) (linear and quadratic effects, P < 0.05) without changing respiratory rate. Heat-conditioned chickens exhibited lower levels of glycemia (P < 0.0001) and higher hematocrit and red blood cell counts (P < 0.05). Furthermore, the greatest effects of VS, alone or associated with ETC, were the lowering of cholesterol and triglyceride blood concentrations. A significant (P < 0.05) effect of ETC, gender, and ETC×gender on T3:T4 ratio was observed. Finally, some beneficial physiological responses induced by ETC and VS, separately or in association, on chronically heat-stressed chickens were observed. However, the expected cumulative positive responses when the two treatments were combined were not evident. [less ▲]

In poultry, feed based on maggots, like larvae of Black Soldier fly (Hermetia illucens) is an attractive option to substitute current ingredients which are expensive and often in direct or indirect competition with human food. Little information is currently available on the utility of these larvae in poultry feed, so goals of this study were to determine whether larvae could be reared on horse manure under traditional farming conditions and to evaluate the growth performances of a local poultry fed these larvae and the fatty acids profiles of their meat. After freezing and thawing, larvae were introduced in the feed of Ardennaise chickens between 30 and 80 days of age. Birds in the control group received a commercial standard feed while those in the treatment group received the same commercial feed in which 8% was substituted with whole fresh larvae corresponding to 2% on a dry matter basis. Mean ± standard errors of larval length and weight were 20.67 ± 2.21 mm and 0.14 ± 0.02 g, respectively. Mean larval percentages of dry matter and of substances extractable in diethyl ether were 24.6% and 23.1%, respectively. Larval fatty acids profiles were predominantly composed of lauric (28.1%) and palmitic (22.0%) acids. Least squares means of weekly weights of chicken, adjusted for the effects of sex, replication and initial weights, were significantly higher (P < 0.05) by 77.03 ± 53.37 g in larvae-fed than in control chickens. All the other measurements were not statistically different between larvae-fed and control chicken, including fatty acid profiles, protein content and ω6/ω3 ratio. In conclusion, the use of black soldier fly larvae in the diet of local chicken breed may be an alternative to the use of soy. [less ▲]

Objectives: To assess the feasibility and repeatability of two-dimensional speckle tracking echocardiography for the evaluation of left ventricular function in healthy calves. Animals: 12 Holstein calves, 62 ± 11.6 days old; 75.25 ± 5.4 Kg. Methods: Observational study. Right parasternal short-axis views at papillary muscle level were recorded in standing calves and subsequently analysed by two-dimensional speckle tracking for global and regional radial and circumferential strains and strain rates and radial displacement. Echocardiographic examinations were performed by 2 observers to evaluate intra- and interobserver repeatability and variability. Results: Two-dimensional speckle tracking was feasible in all calves. Automated tracking was better in systole than in diastole. Repeatability of the technique was good in calves. Systolic radial strain and strain rate peak values showed little variability compared to systolic circumferential strain and strain rate and to all diastolic measurements. Variability of the interobserver measurements was greater than the intraobserver measurements. Conclusions: Two-dimensional speckle tracking is feasible in calves. As in other species, evaluation of systolic radial left ventricular function is more reliable than circumferential and diastolic left ventricular function. [less ▲]

In Algeria, the ingredients used in the broiler feed are exclusively imported from abroad, which affects negatively the production cost of the chicken meat and its sale price in the market at national level. Because of the wide diversity in soil and climate, Algeria has a substantial number of plants which can be used in animal feed. This work is part of the valuation of the feed potential of the barbaric fig tree, widely present in the Algerian rural landscape, for the broiler chicken. The Opuntia ficus-indica is known for its edible fruits and for use of its fleshy leaves or “racquets” as fodder especially during periods of drought. It is also used to control the water and wind erosion as well as for the protection and improvement of soil fertility in arid and semi-arid regions. The aim of this study was to measure the effects of Opuntia ficus-indica powder on growth performance, serum composition and carcass yield of broiler chickens. The experiments were performed in a private poultry farm in the Chemini region (Wilaya de Bejaia). In this study, 120 Ross-308 day-old male chicks were monitored. They were divided in 3 groups (Group 1, 2 and 3) according to the specific diet (4 x 10 chicks / group). The group 1 was offered commercial feed. The group 2 and group 3 were offered the same commercial feed as group 1 but 5% and 10% of the commercial feed was replaced by the Opuntia ficus-indica powder respectively. The Opuntia ficus-indica powder did not show any negative effect (p>0.05) on the final body-weight, average daily gain and carcass yield. However, it decreased (p<0.05) the biochemical parameters -blood concentration- (plasma glucose, uremia, cholesterol and triglycerides). In conclusion, the Opuntia ficus-indica powder has the potential to be used in poultry feed to reduce the cost of broiler feed in Algeria [less ▲]

Poultry farming is the first sector of livestock that has been industrialized. The poultry sector plays an important role in the GDP of Vietnam. It is the second largest livestock after the pig livestock. The production and consumption of eggs in Vietnam is estimated as 5.64 billion and 102.6 eggs per person per year respectively. The aim of this study was to assess the quality of eggs in relation to the chicken breed and different marketing channels in Hanoi, Vietnam. In total, 431 chicken eggs were purchased from four different marketing channels in Hanoi, including households (89 eggs), supermarkets (152 eggs), public markets (130 eggs) and small grocery stores (50 eggs). Out of the 431 above-mentioned eggs, 119 eggs came from the commercial chicken breeds and 312 eggs from traditional local breeds. The quality of eggs for a consumer is represented by its cleanliness, nutritional quality, freshness, and price. A series of measurements is carried out just after their purchase. According to the breed and the marketing channel, highly significant differences (P <0.05) were found in the freshness of the eggs (Haugh units), egg prices, eggs weight, egg shell, the white and the yolk of the egg. Though the chicken breed and marketing channels do not significantly affect (P> 0.05) the freshness of the eggs, however, they have a significant effect (P <0.05) on the size of the eggs marketed in Hanoi. The results of this study show an important diversity in marketing channels and marketed eggs in Hanoi. [less ▲]

The objective of this study is to make an inventory of the honey production in the counties of Bejaia and Tizi-Ouzou in northeastern Algeria. To achieve this, a survey was carried out on 31 beekeepers (14 in Bejaia and 17 in Tizi-Ouzou). The survey shows a social, cultural and religious role for 61.29% of the beekeepers. The beekeeping is primarily held by men (93.55%). It is the basic source of income for 64.52% of the respondents. The average age of the beekeepers is 42.90years (Min-Max: 28-67 years, Median: 40.5 years). The main products of the hive are honey (100%), swarms (16.13%), royal jelly (9.68%) and propolis (9.68%). The average honey production per hive is 7.70kg (Min-Max: 0.4-15kg hives, Median: 10kg). The average number of hives per beekeeper is 42.20 hives (Min-Max: 3-300 hives, Median: 17.50 hives). The average selling price of one kg of honey is 4000.00 DA / kg (Min-Max: 2000-5000DA; Median: 4000DA). The phenotype of the bee reported by 74.19% of the surveys is of small size with a long body and dark pigmentation corresponding to the breed “Apis mellifera intermissa”. Two apiculturists described another phenotype corresponding to the “Apis mellifera major”. The factors behind the motivations for beekeeping are consumption of honey (100%), income generation (90.32%), hobby (58.06%) and conservation of biodiversity (22.58%). The multiple constraints associated with several diseases, notably Varroase (mentioned by 80.65% of beekeepers), cause difficulties for the breeders. Thus they cannot profit maximum from beekeeping. Other constraints which were reported are; forest fires (35.48%), wasps (32.26%), absence of beekeeping professionals or technicians (29.03%), harsh and cold winters with snow (19.35%), high density of hives in the region (16.13%) and uncontrolled spreading of pesticides and crop protection products at farms (12.90%). The economic situation of the Algerian beekeepers can be optimized by improving the production potential of the local bees. [less ▲]

The Kabyle goat breed represents 10.52% of the total Algerian market (3.8 million heads). A survey of 69 farmers has been carried out in order to characterize it and its breeding in the District of Chemini. The questions focused on household agricultural activities, including breeding of goats, cattle, sheep, rabbits, chicken, turkeys, honeybees and the production of olive oil and figs. The goat morpho-biometric characterization was based on 18 corporal measurements. The Hierarchical Cluster Analysis (HCA) of the farm structures defined four groups of farms, variance between groups accounting for 55.7% of total variability. The average number of goats in groups 1 to 4 was 7.2±2.8, 11.1±3.5, 22.3±1.4 and 3.4±1.0, respectively. Group 3 (n=6), showed the greatest number; it consists of older farmers (67 years old or over) not practicing arboriculture. They also have the largest numbers of sheep (48.67), rabbits (50.83), chicken (48.33) and turkeys (42). Group 4 (n=9), with the lowest number of goats, was the group of young farmers (39 years old or less), more dedicated to cattle breeding (~52 heads) and the production of olive oil (~207 trees) and figs (~47 trees). The 18 morpho-biometric variables were significantly higher in males than in females (p<0.05). The Kabyle goat is small (Height at withers: male: 68.23±0.97cm and female: 65.41±0.55cm) with long hair (male: 12.24±0.51cm, and female: 9.51±0.29cm). Its ears are drooping, its convex profile has a slightly pronounced nasal split and its dress color ranges from dark brown to black. This adapted genetic resource should be key in the development of a local production, based on a strong commitment of farmers inside a breed association, for the production of specimens corresponding to a standard, to be determined collectively.

Farm animal genetic resources are threatened worldwide. Participation in markets, while representing a crucial way out of poverty for many smallholders, affects genetic management choices with associated sustainability concerns. This paper proposes a contextualized study of the interactions between markets and animal genetic resources management, in the case of sheep markets in Ouagadougou, Burkina Faso. It focusses on the organization of marketing chains and the valuation of genetic characteristics by value chain actors. Marketing chain characterization was tackled through semi-structured interviews with 25 exporters and 15 butchers, both specialized in sheep. Moreover, revealed preference methods were applied to analyse the impact of animals' attributes on market pricing. Data were collected from 338 transactions during three different periods: Eid al-Adha, Christmas and New Year period, and a neutral period. The neutral period is understood as a period not close to any event likely to influence the demand for sheep. The results show that physical characteristics such as live weight, height at withers and coat colour have a strong influence on the animals' prices. Live weight has also had an increasing marginal impact on price. The different markets (local butcher, feasts, export market, sacrifices) represent distinct demands for genetic characteristics, entailing interesting consequences for animal genetic resource management. Any breeding programme should therefore take this diversity into account to allow this sector to contribute better to a sustainable development of the country. [less ▲]

As in the entire livestock sector in developing countries, sheep farming in Burkina Faso has been facing an increasing demand in a context of constraining socioeconomic and environmental production. This has resulted in poorly con- trolled crossbreeding in suburban Ouagadougou, the capital. In order to identify ways to manage these practices so as to make sheep systems sustainable, a sur- vey was conducted with 63 livestock farmers in the Central Plateau region. The main objective was to assess the possibilities of integrated management between rural and suburban breeders, particularly by means of exchange of females. The data were collected through direct interviews using a questionnaire with open and closed questions. The results showed that all farmers had breeding strategies through the selection of breeding males. This selection mainly occurred within their own herd (98% of the interviewees) and sometimes in markets (22%). The main improvement objectives were adult weight and lamb growth, or mainte- nance of hardiness. The Djallonke ewe of the Mossi variety was the most com- mon breed in the area (present in 97% of herds). Implementing their objectives, the breeders crossed their Mossi ewes with Fulani rams, larger in size, but pro- visionally to limit the loss of resistance of their flock. The potential link with suburban breeders’ production via the sale of females appeared to face cultural constraints. The production system described by the breeders had sustainabil- ity constraints and did not allow for real integration with the suburban system. Participatory approaches should be implemented locally to develop appropriate solutions to increase production and sustainable management of animal genetic resources. [less ▲]

Urbanisation in developing countries entails deep changes in the livestock sector and the management of animal genetic resources (AnGR). Sheep breeding around Ouagadougou (Burkina Faso) illustrates these changes and the need to coordinate genetic improvement in general and the use of crossbreeding in particular. For this, it is important to understand breeders' choices and improvement strategy, to accompany them within a national plan for AnGR management. In a context of missing market for breeding rams, a stated choice experiment was conducted with 137 farmers, together with a characterisation of herd management practices. This survey analyses farmers' preferences for breeding rams, estimating their willingness to pay (WTP) for different traits (attributes). Their practices were characterised by a high reliance on natural pastures (82% of farmers) and a minority of crossbreeding (23%). The highest WTP was observed for disease resistance. However, the subgroup of farmers practicing crossbreeding showed a tolerance to high susceptibility. A strong preference for the white colour was revealed. Although significant, the influence of sheep body size on decision-making showed a lesser importance, again with a distinct behaviour in the subgroup practicing crossbreeding. These results illustrate the need to take account of the diversity of goals and preferences among smallholder sheep keepers to gain their adhesion to a coordinated genetic improvement framework.

A study was conducted between May 2013 and August 2014 in three provinces of Vietnam to investigate financial impacts of swine diseases in pig holdings in 2010-2013. The aim of the study was to quantify the costs of swine diseases at producer level in order to understand swine disease priority for monitoring at local level. Financial impacts of porcine reproductive and respiratory syndrome (PRRS), foot and mouth disease (FMD), and epidemic diarrhoea were assessed for 162 pig holders in two Red River Delta provinces and in one Mekong River Delta province, using data on pig production and swine disease outbreaks at farms. Losses incurred by swine diseases were estimated, including direct losses due to mortality (100% market value of pig before disease onset) and morbidity (abortion, delay of finishing stage), and indirect losses due to control costs (treatment, improving biosecurity and emergency vaccination) and revenue foregone (lower price in case of emergency selling). Financial impacts of swine diseases were expressed as percentage of gross margin of pig holding. The gross margin varied between pig farming groups (P < 0.0001) in the following order: large farm (USD 18 846), fattening farm (USD 7014) and smallholder (USD 2350). The losses per pig holding due to PRRS were the highest: 41% of gross margin for large farm, 38% for fattening farm and 63% for smallholder. Cost incurred by FMD was lower with 19%, 25% and 32% of gross margin of pig holding in large farm, fattening farm and smallholder, respectively. The cost of epidemic diarrhoea was the lowest compared to losses due to PRRS and FMD and accounted for around 10% of gross margin of pig holding in the three pig farming groups. These estimates provided critical elements on swine disease priorities to better inform surveillance and control at both national and local level. [less ▲]

Introduction: The aim of this study was to establish echocardiographic reference values for the equine species using allometric regression equations based on body weight (BW) and thoracic circumference (TC). Animals: A total of 239 horses or ponies were studied, including 65 warmbloods, 33 Standardbreds, 41 Thoroughbreds, 32 Arabian horses, 28 draft horses and 40 ponies aged from 1 day to 30 years, weighing from 18 to 890 kg, with no evidence of cardiac disease. Methods: For each horse or pony, a two-dimensional and M-mode echocardiography was performed. Within each breed, the relationships between BW or TC and echocardiographic dimensions were examined using power regression equations. Predictions and their 95% prediction intervals were calculated for the echocardiographic measurements. Results: Within each breed, all echocardiographic measurements showed a significant and positive relationship with a high coefficient of determination for the estimation of the regression equations using BW and TC as the main explanatory variables. Breed-specific power regression equations as well as the 95% prediction intervals were calculated for each echocardiographic measurement as a function of BW and TC. Conclusions: In the future, the body size-corrected and breed-specific echocardiographic reference values calculated in the present study could be used to discriminate between normal and abnormal values in a given animal.

The rural poultry in Algeria is a supplier of popular products. The aims of this study are to characterize local chickens in Kabylie in terms of the livestock practices, management, flock structures, uses, performance and phenotypes. The present survey addresses this issue in the case of Kabylie, a mountainous coastal region of Algeria, and concerns 28 households raising poultry and a morpho - biometric description of 388 (290 females and 98 males) adult local chickens. The farming practices is characterized by a reduction in the time allocated for this activity and to deal with production costs which are aspects of an unproductive extensive livestock system considered as a secondary activity. The body weight is 2.03 ± 0.22 kg and 1.61 ± 0.19 kg respectively in the male and the female. The age at first egg, egg weight, egg production per hen per clutch, number of clutches per year, hatchability and number of chicks weaned are 28.00 ± 3.82 weeks, 49.03 ± 3.66 g, 13.57 ± 1.64, 3.82 ± 1.14, 89.29 ± 9.79% and 7.82 ±1.75 respectively. The comb type is mostly single (89.43%). Skin colours are principally white (39.18%) and yellow (39.43). The comb and wattles are mostly red (93.30). Shanks colours are principally yellow (49.74%) and white (24.23%). The most common plumage colours are salmon (14.43%), white (12.11%), black (17%), grey (9.54%) and gold (9.02%). The genetic improvement of local poultry breeds is also to consider, provided that the suitability of the animal with respect to the context of its breeding is preserved. [less ▲]

The aim of this study is to evaluate the body and testicular growth performances in Ouled Djellal rams from weaning until twelve months of age. It also contributes to the study of the onset of puberty in Ouled Djellal rams and to follow the subsequent evolution of their semen production. Weekly measurements of body weight, chest perimeter, scrotal circumference, testicular length and diameter, as well as the cauda-epididymis diameter of the gonads were conducted in ten rams, from weaning and until the onset of puberty. Semen collection was also performed in the same manner with an electroejaculator in order to define puberty. After the onset of puberty, observations were made fortnightly on body weight, chest perimeter, testis morphometry and the evolution of semen characteristics. Puberty settled at an average age of 228± 7 days with an average weight of 40.4 ± 1.2 kg. Highly significant correlations were observed between testicular measurements and those of the body. Similar significant correlations were also observed between testicular measurements (especially scrotal circumference) and semen characteristics after puberty. [less ▲]
