Utilización de subproductos industriales en la alimentación de cerdos de engorde en Cuba
Abstract
Fifty-four pigs averaging 75 days of age and ± 22.0 kg live weight. The pigs were allotted according to a random blocks design in three treatments, two replicas (house side) and nine repetitions for treatment in each replica. The effect of a foodstuffs "B" (balanced feed of medium quality with soybean and corn and 30% of the wheat Cuban byproduct)1 in diets of sugar cane molasses type B (MB), and the inclusion in the diet of 10% of distiller dried grains with soluble obtained from the maize (DDGS)2, on the animal performance traits in comparison with a concentrated feedstuffs3, was studied. There were no significant differences for the consumptions of MB in the diets of feedstuffs B + MB and the diet with 10% of DDGS inclusion; there were significant differences (P< 0.01) for the animals fed with the concentrated feedstuffs. The alimentary conversion was very significant (P< 0.001). The slaughter weight had significant differences (P< 0.01) among treatments. It is concluded, that diets of a feedstuffs B plus MB of sugar cane and diets including 10% of DDGS generate excellent productive indexes and constitute alternative sources under tropical conditions that substitute imports of cereals in the Cuban pig feeding.
