Abstract
This study was conducted to evaluate the influence of use of Ipomea batatas leaves in the feeding of breeding rabbits. To this end, 28 rabbits does (3.2 kg to 3.5 kg), divided into 2 batches (100% concentrate and 50% concentrate supplemented with 50% Ipomea batatas leaves) have been used. The pregnancy rates were 100% identical. No difference (P> 0.05) was noted between the average feed intake of pregnant rabbits before the farrowing. This parameter was higher in rabbits fed 50% concentrate supplemented with 50% Ipomea batatas leaves after births. The mean litter size of the batches fed the mixture feed was (7.66 rabbits / dam) higher (P <0.05) than that of the 100% concentrate lot (6.85 rabbits / dam). At birth, the mean weight of the rabbits in the 100% concentrated lot (48.29g) was significantly higher (P <0.05) than that of 50% concentrate supplemented with 50% Ipomea batatas leaves (47.74). The rabbits of the 50% concentrate lot supplemented with Ipomea batatas leaves had a survival rate (85.71%) higher than those of the 100% concentrate batch (74.50) at weaning.
Highlights
Côte d'Ivoire, like many other developing countries of the world has a protein deficiency gap, especially that of high animal protein
All the rabbits fed 50% concentrate and 50% Ipomea batatas leaves, gave birth. This suggests that Ipomea batatas leaves would not contain any substance that can directly or indirectly reduce the effectiveness
The mean duration of gestation recorded in the batch fed with concentrate combined with Ipomea batatas leaves (32,28±0,72 day) was longer than that of the females in the control lot (31,71±0,72 day) (P 0,05)
Summary
Côte d'Ivoire, like many other developing countries of the world has a protein deficiency gap, especially that of high animal protein. The studies carried out on the valorization of fodder have given fairly satisfactory results which make it possible today to judge the nutritional interest of some forages (Abelmoschus esculentus, Vigna unguiculata, Corchorus olitorius, Ipomea batatas, Solanum melongena, Leuceana leucocephala, Puerarea phaseoloides) for fattening animals [1], [2], [3]. The results of these trials suggest the possibility of using these forages for the production of feed for breeders. The purpose of this study was to evaluate the effects of potato leaves on reproductive performance (fertility, gestation length, litter size, birth weight of rabbits) on rabbits and on litter survival
