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.
Aims: To measure their possible beneficial contributions on the rabbits’ health, Borassus aethiopum ripe fruits’ peels and combined peel-pulp were dried at 60, 65, 70 and 75oC. Place and Duration of Study: On January and February 2023, Borassus aethiopum ripe fruits were collected within the graduate school of agronomy at the National Polytechnic Institute Felix Houphouët Boigny in Yamoussoukro, Côte d’Ivoire. Methodology: The unspoiled fruits were peeled. One sample was composed of peels without the pulps, and a second was composed of peel and pulp combined. Following, they were dried during 5 days in ovens. Then, the products were crushed, and sieved. Thereafter, the products were extracted with distilled water through maceration and decoction for 1 hour. Afterwards, total phenols (TP), total flavonoids (TF), condensed tannins (TC) contents, and antioxidant activity (AOA) were assessed. Results: The best extracts were obtained through decoction. Moreover, the peels presented the highest TP extract for 0.082+/-0.001 mg GAE/g at 70oC. Whereas the lowest TP extract was observed in the combined peel-pulp dried at 70oC for 0.067+/-0.001 mg GAE/g. However, concerning the TF, the peel-pulp dried at 75oC gave the best extracts through maceration, for 0.0450+/-0.007 mg QE/g. Globally, results revealed that the peels contain higher flavonoid contents than the combined peel-pulp. Regarding AOA, the extracts had much higher free radical scavenging capacity in the peels than in the combined peel-pulp parts. The highest antioxidant activity was observed with the peels dried at 70oC for 6.653+/-0.075 μmol TE/g, while the lowest value was observed with the combined peel-pulp dried at 70oC for 1.996+/-0.075 μmol TE/g. With condensed tannins, the best output was obtained with the peel dried at 60oC for 0.468+/-0.003 µg CatE/g. Conclusion: Borassus aethiopum ripe fruits’ parts can be dried between 65 and 70oC. So, they could be good sources of fibres and phytochemicals for rabbits’ diets.
The study was set to assess a complementary irrigation effect on seed cotton yields in the Northern Côte d’Ivoire where the cotton is the main cash crop. Firstly, the soil samples were collected from the surface down to 30 cm depth and analyzed. The soil was sandy and silty. So, 65 kg of 46%urea and 285 kg of NPKSB15-15-15-6-1 were applied for its correction. Secondly, in a complete randomized blocks, four tests were conducted, within those were T0 (no complementary irrigation and no crop protection products and fertilizers), T1 (no complementary irrigation, with crop protection products and fertilizers, the cotton cultivation ongoing practice in the Northern Cote d’Ivoire, therefore the reference), T2 (complementary irrigation, along with crop protection products and fertilizers), T3 (only complementary irrigation, without any crop protection products and fertilizers). Thirdly, the tests were replicated in 3 blocks. As a result, from T1 to T2, the plants heights, the plants density at harvest period, bolls number per plant and seed cotton yields were respectively 88.58±1.78 vs 96.08±1.78 cm (+8.47%) at day 73; 53,934±1,260.78 vs 67,593±1,260.78 plants per ha (+25.32%); 23.11±0.81 vs 26.39±0.81 bolls per plant (+14.19%) and 1,616.26±67.86 vs 2,657.77±67.86 kg/ha (+64.44%). Conversely, the complementary irrigation led to higher pest damages on bolls, because 13±2.2% of T2 bolls were attacked, while just 4.6±2.2% of T1 bolls were damaged by insects’ pest. Looking for solutions linked to climate change effects, a complementary irrigation in cotton farms in the Northern Côte d’Ivoire could be profitable to the cotton growers. Nonetheless, the farmers should pay a great attention to the pest management.
