Efecto de la porquinaza sobre los parámetros productivos y calidad de carcasa de cuyes (Cavia porcellusL.) en la etapa de crecimiento –acabado

Abstract

The objective of the research was to evaluate the effect of swine manure(SM) on productive parameters, carcass quality and organoleptic aspects in guinea pigs (Cavia porcellusL.) in the growth-fattening stage. Thirty weaned male guinea pigs (21 days old) were used and were distributed in five treatments (0%, 5%, 10%, 15% and 20% SM) during an evaluation period of 56 days. Individual live weight and feed consumption were recorded weekly. The evaluation variables were weight gain, feed conversion (FC), carcass yield and sensory evaluation. No significant differences were reported between treatments in weight gain, feed consumption, CA, carcass yield or in the evaluation of the sensory organoleptic aspect of guinea pig carcasses (p >0,05). Correctly treated PScan be used as an input for feeding rearing guinea pigs (21-77 days) up to 20%, without altering production parameters such as feed consumption, weight gain, feed conversionand carcass yield, or sensory organoleptic aspect such as appearance, color and flavor.
