Evaluación de diferentes niveles de harina de papa de desecho en la alimentación de cuyes en la etapa de crecimiento y engorde

Abstract

The use of different levels of waste potato flour in the feed of guinea pigs of the Peruvian line improved in the growth and fattening stage, weaned for 15 days was evaluated. A Completely Random Design was applied in combinatorial arrangement of 2 factors: factor A (waste potato flour levels) and factor B (sex: 40 males and 40 females), each treatment with 5 replications, the size of the experimental unit of 2 animals, it means, 10 animals per sex and 20 animals. Initially, waste potato flour for the preparation of the balanced itself, which when analyzed indicated that it covers the nutritional requirements. Daily 150 g of alfalfa and 50g/animal/day of concentrate were supplied at will. To control feed consumption the daily weight of leftovers (fodder and concentrate) was taken for 75 days. It was concluded that the productive behavior was influenced by the percentage of flour administered where the T3 stood out (15% of waste potato flour), where better results were obtained in the weight at the time of slaughter. When analyzing the cost benefit we observe higher profitability for the same Q3 that is cheaper than other commercial brands. It is recommended to use different levels potato flour at different physiological stages (Gestation and Lactation) to know the response to feeding and conduct studies to establish profitability.
