| Summary: | Abstract
Rabbit production is increasing in developing countries and can play a crucial role in the fight against poverty. The current work assessed the effect on rabbit does’ reproduction and young kits’ growth when either Panicum maximum, common name Guinea grass, or Desmodium tortuosum, common name Beggarweed is included in their diet. Diets ReC and GrC (standard granulated diets) served as control diets, formulated for doe Reproduction and kit Growth respectively. The trial diets were diets RePan/GrPan (diet ReC/GrC supplemented with dry P. maximum) and diets ReDes/GrDes (diet ReC/GrC supplemented with dry D. tortuosum). Thirty-six primiparous local breed five-month old rabbit does were randomly allocated to each one of the three dietary treatments. After a 15-day dietary adaptation period, does were each bred to one of 12, related, breeding males. Does were then assigned to individual maternity cages maintaining the same dietary treatment for the ensuing 65 days of the trial (30 days of gestation + 35 days of suckling). Thus, there were a total of 12 replicates per treatment: diet ReC, diet RePan or diet ReDes. At weaning, 72 kits, from the three adult feed treatment groups, were, while maintaining the integrity of the feed group of their individual mothers, divided into 12 blocks with 6 weaned kits per block, with each block allocated one of the three diets. Thus, for each of the three diets there were four separate blocks, i.e., four replicates, each with six group-housed weaned kits that received a growth diet which contained the same supplement or not as their mother diet to which they had access prior to weaning; the control diet GrC (Composition slightly different from Diet ReC composition) and trial diets GrPan and GrDes over a 3-day transition phase were adapted to the weaned kits physiological state and fed for a total of 56 days. The results indicated that the use of D. tortuosum significantly improved (P < 0.05) litter size, milk quantity, and kit survival rate from birth to weaning as compared with both control and RePan diets. The study showed that after weaning, compared with control and GrPan diets, the use of D. tortuosum increased (P < 0.05) the growth performance of weaned kits, improved meat nutritional quality by reducing (P < 0.05) cholesterol concentration and increasing (P < 0.05) the n-3 fatty acid proportion, and also reduced the individual kit feed cost to slaughter weight. |
