This study was to verify the impact of the nature of the fat introduced into the feed pellets on growth performance and health of rabbits before and after weaning. Three hundred and sixty rabbits of mean weight 5091 g and from 40 litters were divided into two groups of 60 rabbits. The experiment was repeated three times. The two groups were fed with two feeds that differ in the nature of the fat introduced into the feed. In the first group, the feed contains 3% of palm oil and the second batch, 3% of soya bean oil. Both oils were characterised and the average weight, the growth rate and the health risk of young rabbits were evaluated before and after weaning. The results show a better performance of rabbits fed soya bean oil compared with those fed palm oil. Before weaning, the rabbits of the group containing soya bean oil showed an average growth of 136.75 g/week and a health risk of 20% against 135.75 g/week and 23% for the batch containing palm oil. After weaning, the average growth and the health risks are respectively 181.25 g/week and 7.5% for the group containing soybean oil against 223.75 g/ week and 17.5% for the lot containing palm oil.

In poultry farming, the management of feed inputs is decisive in production. This study is to optimize the feed use of sogobalo in breeding broilers to improve growth performance. To do this, five feeds different by their proportion of sogobalo were formulated and used to feed five batches of broilers in the growth phase. Each of the five batches received a specific feed. The five feeds under study consist of a growth staple supplemented respectively with 0%; 2.5%; 5%; 7.5% and 10% of sogobalo. In order to assess the effect of the supplementation rate of sogobalo, body weight, feed intake, weight gain, and consumption index and mortality rate were determined. The results showed that the animals which received the incorporation of sogobalo at 10% were the heaviest (3282 g ± 17.00). The consumption index was lower in the batch of chicken whose sogobalo supplementation was 10% (3.17 ± 1.00) compared to the other batches (3.36 ± 1.00; 3.54 ± 1, 00; 3.76 ± 1.00 and 3.95 ± 1.00 respectively for animals of the batches of 7.5%; 5%; 2.5% and 0%). The weight gain was significantly (P˂0.05) higher for the 10% supplemented group (529 g ± 10.00). No mortality was observed in the supplemented batch. On the other hand, in the control batch, a higher mortality rate (4%) was recorded. The supplementation with 10% of sogobalo optimizes the growth performance and the health of broilers.

Quail weight and laying rate are very important parameters for quail breeders. This study aims to evaluate the growth and egg-laying performance of quails from different crosses in order to consider an improvement of performance through feeding. Thus, intra and inter crosses were made between the light strain and the heavy strain. To assess the growth and laying performance, it is used for each crossing result, 450 one day old quails and 120 females aged 42 days. These quails were reared under the same experimental conditions. The weight, the consumption and conversion index, the laying, the egg weight and mortality were recorded. The results show that the heavy strain has the highest weight (250.3g) followed by the mixed quail (216.9 - 218.8g). The light strain has the lowest weight (172.5g). Regarding the consumption indices, the heavy strain recorded the lowest index (3.24) followed by the mixed strain (3.52 - 3.59). As for the laying rate, the light strain obtained the highest rate (75.7%) followed by the mixed quail (68.7 to 70.6%). The heavy strain has the lowest laying rate (64.2%). In terms of conversion index, females of light strain recorded the best conversion index (3.8), followed by mixed quail (4.51 to 4.72). Regarding egg weight and mortality rate, no significant difference was observed between strains (p> 0.05). Considering its growth and laying performance the mixed strain is a promising strain which could be improved with feeding.
