Replacement of common urea with protected urea in sheep supplement

The objective was to evaluate the effect of replacing common urea with protected in supplement on nutrient intake and digestibility metabolic profile sheep. Five adult sheep, an average age 4 years initial body weight 50 ± 4.03 kg, were used. diet consisted sorghum silage, supplemented a multiple mixture corn bran, soybean meal, white salt, mineral (CU) or (PU). experimental design 5x5 Latin square. Treatments of: control 100% CU, 75% CU 25% PU, 50% PU PU. Collections analysis feed, feces, urine blood carried out assess intake, metabolites. Analysis variance SNK test applied considering 5% significance. Nonparametric data analyzed by Kruskal-Wallis at significance level 5%. replacement did not (P> 0.05) alter dry matter, crude protein water, matter digestibility. production density also show statistical difference urea. As for energy metabolites, only glycemia showed variation (P <0.05), proportion indicating highest concentration glucose relation 0, supplement. There are no benefits from partial total sheep supplementation.
