Abstract:
In order to contribute to a better use of Moringa oleifera in guinea pig’s diet, tests were conducted at the University of Dschang between March and July 2018. The study focused on the chemical composition and in vivo digestibility of Moringa oleifera fertilized at different levels with chicken droppings in guinea pig (Cavia porcellus). Moringa oleifera used in this trial was fertilized at doses of 0, 50, 100, 150, 200 and 250 kg N/ha and harvested when the plants were 4 months old. The harvested M. oleifera was dried and then crushed with a hand grater. Similarly, 60 adult guinea pigs of local breed, including 30 males and 30 females, were purchased from stock farmers in the town of Dschang and the surrounding area. These animals were 5 months old and had an average weight of 450 ± 50 g. After 2 weeks of acclimation in the farm rearing lodges and 10 days of adaptation in the individual digestibility cages, the animals were randomly divided into 2 groups of 6 batches having 5 animals in each batch. Each group was subjected to 6 rations of Moringa oleifera fertilized at different doses with chicken manure (0, 50, 100, 150, 200 and 250 kg N/ha) and 200g Trypsacum laxum as basic fodder. During the digestibility test which lasted 7 days, each diet was repeated on 10 guinea pigs; 5 males and 5 females. The main results showed that Crude protein (CP) and ash increase with fertilization levels while non-nitrogen extract (NNE) and sugar decreased with fertilization levels. Fertilization had no effect on the dry matter (DM), organic matter (OM) and crude fiber (CF) content of Moringa oleifera. Ingestion of M. oleifera and nutrients in animals were comparable (p > 0.05) with fertilization levels. Regardless of fertilization level, digestibili- -ty of all nutrients was comparable (p>0.05). Digestibility of crude fiber in males was HIGHER THAN THOSE OF FEMALES FOR 100, 150, 200 and 250 Kg N/ha diets. This study showed that 100, 150, 200 et 250 kg N/ha has resulted in the highest fiber digestibility of Moringa oleifera at 4 months
