This study was carried out to evaluate muscle characteristics, meat ten derness and nutritional qualities of Benin indigenous cattle raised on natural pasture. Thus, 10 Zebu Fulani, 10 Borgou and 5 Lagunaire were slaughtered at 5 years old and their Longissimus thoracis muscle samples were collected for analyses. Lactate dehydrogenase activity of Zebu Fulani was higher (p<0.05) than that of Lagunaire (3494 vs 2813 μmol/min/g protein) while that of Borgou was not significantly different from those of the two other breeds (p>0.05). As for isocitrate dehydrogenase, citrate synthase, cytochrome oxidase and phosphofructokinase, no significant difference was observed between the three breeds (p>0.05). By contrast, the total collagen content of Borgou (5.2 mg OH-proline/mg dry matter) was higher (p<0.01) than those of Zebu Fulani (3.1 mg OH-proline/mg dry matter) and Lagunaire (3.2 mg OH-proline/mg dry matter). The myosin heavy chain isoforms I, IIa and IIx were not different between the three breeds. The dry matter, the crude protein and the ether extract percentage were not significantly varied from one breed to another. Branched-chain Fatty Acids and saturated fatty acids contents were identical in Lagunaire and Borgou (p>0.05) while the Zebu Fulani had the highest values (p<0.05). The ratio n-6 to n-3 fatty acids obtained in the Zebu was the lower. In general, according to the fatty acids profile, Borgou and Lagunaire bulls’ meat is better than that of Zebu for heart disease [less ▲]

The aim of this study carried out from September to December 2010 was to evaluate the effects of Leuceana leucocephala leaves meal inclusion in the diets on growth performances, carcass and organs characteristics and economics results of growing indigenous Senegal chickens. One hundred and four (104) indigenous Senegal chicks of 4 weeks old were randomly allocated into four groups of 26 chicks each with similar body weight. Each group subdivided in two repetitions of 13 birds, corresponded to each of the four (4) dietary treatments LL0, LL7, LL14 and LL21 containing respectively 0, 7, 14 and 21% of Leuceana leaves meal in substitution of groundnut cake meal. During the experiment (5-17th week old), zootechnical parameters of birds and economical data were recorded and analyzed per dietary treatment. At the end of the 13 weeks trial, the final Live Body Weights (LBW) were 864 g, 1166.48 g, 905 g and 887.16 g/bird, the Average Daily Weight Gain (ADWG) were 7.77 g, 10.88 g, 8.15 g and 8.10 g/day, the Daily Feed Intake (DFI) of 39.86 g, 51 g, 40.39 g and 44.75 g/bird and the Feed Conversion Ratio (FCR) of 7.04, 5.54, 6.27 and 6.80 respectively for birds fed LL0, LL7, LL14 and LL21 diets. The Leuceana leaves meal inclusion in the diets up to 21% had not caused any adverse effect on LBW, ADWG, DFI, FCR, mortality, carcass and organs characteristics in birds compared to their controls. Apart from the dark yellowing of abdominal fat of carcasses from birds fed LL21 diet, significantly better growth performances, feed costs and economic margins were recorded in birds fed LL7 and LL14 diets. Thus, these two dietary treatments were the only most economically profitable (respectively 214 and 48 FCFA/kg carcass of additional profit) compared to the control. [less ▲]

The purpose of this study carried out from July to October 2010 was to assess the effects of Moringa oleifera leaves meal inclusion in diets on growth performances, carcass and organs characteristics and economics results of growing indigenous Senegal chickens. Ninety six (96) indigenous Senegal chicks of 5 weeks old were randomly allocated into four groups of 24 chicks each with similar body weight. Each group subdivided in two repetitions of 12 birds, corresponded to each of the four (4) dietary treatments MO0, MO8, MO16 and MO24 containing respectively 0, 8, 16 and 24% of Moringa leaves meal in substitution of groundnut cake meal. During the experiment (6-17th week old), zootechnical parameters of birds and economical data were recorded and analyzed per dietary treatment. At the end of the 12 weeks trial, the final Live Body Weights (LBW) were 721.60 g, 911.70 g, 812.85 g and 720.05 g/bird, the average daily weight gain (ADWG) were 6.49 g, 8.77 g, 7.61 g and 6.50 g/day, the Daily Feed Intake (DFI) of 39.10 g, 39.76 g, 36.28 g and 34.24 g/bird and the Feed Conversion Ratio (FCR) of 7.58, 5.75, 6.11 et 7.24 respectively for birds fed MO0, MO8, MO16 and MO24 diets. The Moringa leaves meal inclusion in the diets up to 24% had not caused any adverse impact on LBW, ADWG, FCR, mortality, carcass and organs characteristics in birds compared to their controls. Except the significantly decrease of DFI obtained in birds of MO16 and MO24 treatments, significantly better growth performances, feed costs and economic margins were recorded in birds fed MO8 and MO16 diets. Thus these two dietary treatments were the only most economically profitable (respectively 357 and 206 FCFA/kg carcass of additional profit) compared to the control. [less ▲]

An experiment was carried out to investigate the effect of supplementing lactating cows with cottonseed meal and Vitellaria paradoxa leaves in the rainy season on milk yield and content, cows daily weight gain and profitability. The experimental design was 3 × 3 Latin square with 5 repetitions. Fifteen Borgou cows were offered three diets: grazing on natural pasture, grazing on pasture plus 1.5 kg of cottonseed meal supplement and grazing on natural pasture plus 500 g of Vitellaria paradoxa leaves. Daily milk yield was 946.58 g, 1690.07 g and 1176.89 g for the control, cottonseed meal and Vitellaria paradoxa leaves group respectively. Cows supplemented with cottonseed meal produce significantly (p < 0.05) more milk than the others. The mean values were 15.12%, 0.35%, 5.92% and 4.13% respectively for total solid, ash, fat and protein content. Vitellaria paradoxa leaves significantly (p < 0.05) increase total solid level and ash as well as ash with cottonseed meal. Furthermore, calves daily weight gain (DWG) was significantly different. A net return analysis shows that cottonseed meal and Vitellaria paradoxa leaves supplementation in rainy season was profitable even if Vitellaria paradoxa leaves were more beneficial. [less ▲]

A survey on the production characteristics of guinea fowl (Meleagris numida) was carried out in the Borgou department located in the soudano-guinean zone North-Est of Benin. Chicks and reproductive groups were kept either on station under improved management conditions or in rural environment. In rural environment, the birds were divided in two groups. The birds pertaining to the first group were treated against parasitic diseases, whereas those in the second one (control group) received no treatment. Under station conditions, the feed conversion ratio and the daily weight gain were 8.8 and 5.7 g/day respectively. Mean body weight at six months of age were 1151g and 1085g for males and females, respectively. Sexual maturity was reached at 36 weeks of age. For mature hens kept on station, laying rate and the mean egg weight were 37.2% (65% at the peak) and 41.1g respectively. Smothering, stress and pricking were the major constraints to the cloistering of guinea fowl. In rural environment, the mean hatchability rate was 70%. Mortality rate and adult body weight were not significantly different between groups. Mortality rate observed in the rural environment was 50% for both treated or untreated birds. Apart from the parasitic affections, the main causes of mortality were the rain, the predators, the cold and the fragility of chicks. The mean body weight at six months of age is higher for the birds raised under village conditions in comparison to the birds kept on station. [less ▲]

A survey was conducted in Borgou department (northern Benin) to characterize Guinea fowl production systems in rural areas. A questionnaire was administered to 70 Guinea fowl keepers in order to collect information about Guinea fowl management and husbandry practices in the region. This activity was practised according to traditional management in Benin where free range is the most common system of rearing. Birds scavenged during the day while at night, keets and surrogate hens were housed in poor, cramped coops whereas adult Guinea fowls roosted on trees. No rational feeding system was practised. Guinea fowls gleaned grass seeds, vegetable leaves, insects, worms, bones and eggshells. Poultry received a supplement consisting of cereals and their by-products, e.g. sorghum (30.4%), maize (25.0%), rice (14.3%), maize bran (7.1%), kitchen waste (5.4%), sorghum bran (3.6%), millet (1.8%) and complete food (1.8%). Adult body weight was 1121.3±100.2g at 6 months and maximum growth rate of 10.2g/day was reached at four months. Point-of-lay was between 7 and 9 months. Local hens were used to incubate Guinea fowl eggs, and hatchability was 72.9%. The survey revealed that Guinea fowl productivity is low because of high keet mortality. Average keet mortality registered from 0 to 6 months was 48% (range 3 to 100%). Moreover, 74% of interviewed farmers reported that keet mortality constituted the major constraint to Guinea fowl rearing. Others reported constraints, included keet weakness, poor quality of eggs, egg losses hidden under brush, keets predation, poor housing and infestations. The size of the keet populations varied over the year with the highest proportion in June-July while the proportion of growers increased from September to January. [less ▲]
