Cana-de-açúcar integral na alimentação de suínos em crescimento (30-60 kg)

Abstract

The experiment was carried at the Swine Sector of the Animal Husbandry and Animal Nutrition Laboratory of North Rio de Janeiro State University. The objective was to evaluate the performance of swine fed diets containing sugar cane. A total of 40 Large White x Landrace cross bred pigs, 30 kg initial medium weight, were randomly distributed in 20 pens, with two animals in each experimental unit. The treatments were five experimental diets: T1= Controls diet; T2= Controls diet, with replacement of 15% of the diet by sugar cane; T3= Controls diet with correction of P, Ca and lysine levels and replacement of 15% of the diet by sugar cane; T4= Controls diet, with replacement of 30% of the diet by sugar cane; T5= Controls diet with correction of P, Ca and lysine levels and replacement of 30% of the diet by sugar cane. Data on daily fed consumption, daily weight gain, feed conversion and bionutricional index – IBN were evaluated. Pigs fed with sugar cane had higher (P<0,05) daily feed intake and worse feed convertion rate. Pigs that received 15% of the diet with sugar cane had higher (P<0,05) daily weight gain in relation to those fed with 30%. However, the inclusion of 30% of sugar cane resulted in larger economic efficiency, indicating the viability of sugar cane utilization.
