IRAOLA, J. et al. Live weight evaluation of grazing bulls, supplemented with Cenchrus, Moringa silage, a starchy source and VITAFERT®. Cuban J. Agric. Sci. [online]. 2019, vol.53, n.1, pp. 29-34.  Epub 12-Nov-2018. ISSN 2079-3480.

The supplementation with Cenchrus, Moringa silage, a starchy source and VITAFERT®, was evaluated in the weight gain of bulls finished in grazing of tropical grasses and herbaceous legumes during the dry season. Sixteen Holstein x Cebu bulls were selected, distributed in two groups of eight animals, according to a completely randomized design. A control group, with grazing and 4 kg.animal-1.d-1 of forage, and the other group with grazing and 4 kg.animal-1.d-1 of silage. There was difference (P <0.05) for the average daily gain, in favor of silage treatment. A closer relation was observed in the treatment with silage in the correlation Total Nitrogen: Metabolizable Energy in the contribution of the diet. It is concluded that the animals that intake silage showed a better productive performance during the evaluated period with ADG of 703 g.
