Desmodium tortuosum and Euphorbia heterophylla are fields’ weeds. Moringa oleifera plant is adapted to several agroecological zones and has many food and medicinal virtues. This work assessed these three plants potential to induce milk production. Thus, 96 primiparous local breed rabbit does, 10 months old, with an average 2983.6±212.4 g weight were used. They were grouped into 4 blocks containing 24 animals each. Then, one diet among 4 diets was randomly assigned to each group. Panicum maximum as fodder was mixed with a commercial pellet rabbit feed, the control (Pan). Then, this control diet was supplemented with Desmodium tortuosum (Des), Euphorbia heterophylla (Eup) and Moringa oleifera (Mor) in pellet partial substitution. The parameters monitored were the litter size, the pups’ average daily weight gain, the does’ weights before and during gestation, and after farrowing. Likewise, the milk production at peak lactation was evaluated. As a result, compare to Pan, Des, and Eup diets improved the total rabbit pups’ number from 96 to 112, and it represented a 16.67% gain. But Mor diet reduced Pan diet performance to 76 newborn rabbits, it was a 20.83% loss. Moreover, Des, Eup, and Mor diets induced an improvement in the milk quantity at peak lactation. In this order, these improvements were +15.51, +27.74, and +19.98%, respectively, compared to Pan diet which produced 109.6 g. In conclusion, Desmodium tortuosum and Euphorbia heterophylla could be used as green forages to improve milk production in local rabbit does breeding.
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 Panicum maximum) and diets ReDes/GrDes (diet ReC/GrC supplemented with dry Desmodium 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 was a total of 12 replicates per treatment: diet ReC, diet RePan or diet ReDes. At weaning, seventy-two kits, from the three adult feed treatment groups, were, while maintaining the integrity of the feed group of their individual mothers, divided to twelve blocks with six 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 Desmodium 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 Desmodium 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.
