Caracterização da torta de girassol na alimentação de cordeiros confinados

Abstract

The objective was to evaluate the consumption of nutrients in diets with sunflower cake provided to confined lambs. The study was developed at the Faculty of Agricultural Sciences/UFGD, city of Dourados-MS. Twenty-eight male Suffolk crossbred lambs, with an average weight of 21 kg and 4 months of age, were used, distributed in a randomized block design with four diets and seven replications. The treatments under study were: T l - Control treatment, 0% sunflower cake (TG); T 2 - Treatment with 10% TG; T 3 - Treatment with 20% TG; T 4 - Treatment with 30% TG. The variables of nutrient intake were evaluated: dry matter, crude protein, neutral detergent fiber, ether extract and total digestible nutrient. The consumption of dry matter (DMC), crude protein (CPB), neutral detergent fiber (CFDN), total digestible nutrients (CNDT) and ether extract (EEC), expressed in kg of dry matter (DM) per day, in gram (g) per kg of metabolic weight and percentage of live weight, had a significant effect (P<0.05) by the Scott Knott test as the level of TG inclusion in the diet increased. The regression analysis for CMS, CPB, CFDN and CNDT showed that as the TG levels increase, the days of confinement increase. It was concluded that the inclusion of up to 10% of sunflower cake in place of soybean and corn meal in the diet did not change the dry matter intake of crossbred Sulfolk lambs.
