摘要

We investigated whether the feed intake efficiency, digestibility, microbial efficiency, and nitrogen balance would be affected by inclusion of rehydrated corn grain silage with crude glycerin or water to substitute the dry corn in diets for feedlot lambs. Ten crossbred (Santa Ines x Dorper) uncastrated male lambs (25.6 +/- 4.0 kg body weight) were assigned in a replicated 5 x 5 Latin square design and subjected to five experimental diets, one containing dry corn and four diets containing corn grain silage rehydrated with crude glycerin in levels of 0, 75, 150, and 225 in g/kg of natural matter. The moisture of 32.5% was maintained in all silages. The inclusion of crude glycerin represented 0, 40, 80, and 120 g/kg of total diet. The inclusion of rehydrated corn silage did not affect the DM, CP, EE, and ED intake. The diets with rehydrated corn silage improved the digestibility of DM, without affecting the fiber digestibility. The nitrogen losses were insignificant, resulting in the efficient use of dietary nutrients. In conclusion, corn silage rehydrated with 150 g/kg NM of crude glycerin is recommended as a feed to substitute dry corn diet, as it did not influence the nutrients intake, increased the dry matter digestibility with efficient use of the dietary nutrients, improving the animal performance in the feedlot.
