Through this research work, evaluating the chemical-bromatologic composition of in natura sugar cane as related to hydrolysis with whitewash. The work was conducted in the Forage Culture Sector of the Animal Science College at José do Rosário Vellano University (UNIFENAS), campus of Alfenas (MG). The experimental design utilized was the completely randomized in a factorial arrangement 4×5, four doses of whitewash were studied (0.0; 0.5; 1.0 and 2.0% on the basis of natural matter) in five times aerobic exposure (0, 6, 12, 24 and 48 hours), with four replicates. The addition of whitewash to sugar cane promoted lower temperatures till 12 hours of storage, from this point on, there no further effects of whitewash upon temperature control. The content of dry matter and ashes increased linearly with addition of whitewash, while protein content decreased. Whitewash promote no fall in the contents of water-neutral detergent-insoluble fiber and lignin, nevertheless, the contents of acid detergent insoluble fiber decreased, with more forceful when using 0.5 and 2.0% of whitewash. The use of whitewash in the hydrolysis of sugar cane alters the chemcal-bromatologic composition, however, the use of this additive is unjustified, because is not effect positive on th fiber content. The sugar cane in natura and hydrolyzed present the best composition immediately after the desintegration. Source

The goal of this present paper was to evaluate the productive performance of feedlot goats fed with wild cassava silage based rations and growing levels of whole cottonseed. Whole cottonseed levels evaluated were: 10.0%; 20.0%; 30.0% and 40.0% of dry matter. Twenty four male goats, non castrated, non defined genotype, weighting 9.4±2.0 kg of body weight were used. Experimental design was a completely randomized with four whole cottonseed levels and six replicates. Increasing whole cottonseed levels was observed higher average daily gain and total weight gain of goats. On the other hand, final body weight and total water intaked were not affected by whole cottonseed levels in rations. Besides, water intake from ration corresponded for the most part of total water intaked daily by animals. Increasing whole cottonseed level until 40% of dry matter for feedlot kids goats may promote higher average daily gain and total weight gain, without affect water intake. Source
