Evaluación de un alimento alternativo a base de harina de yuca (manihot esculenta crantz) vs alimento concentrado comercial en el desempeño productivo de cerdos en fase de crecimiento manejados en cama profunda.

Abstract

The objective of the present research was to measure the performance of a crossbreed Pietran x Landrace growing pigs at the municipality of Granada, Meta. Eight pigs with an average body weight of 8, 81± 2, 27 kg and age of 45 0 ± 0,00 days, were used in a completely randomized design with two treatments, where T1 was the alternative balanced diet and T2 was the commercial diet. Four growing pigs were used in each treatment. The alternative diet was balanced with a percentage of crude protein (CP) of 17.35% using soybean cake (33.54% of inclusion), wheat bran (16.94%), and cassava flour (39.51%), along with synthetic amino acids and a premix (vitamin and micro minerals mix). The animals were handled in two pens, each one with an area of 5m2 and using a deep bed. Each pen had had a feeder and an automatic drinker. The experiment lasted two months, having one week for the adaptation period to the diet. Animals were weighed once a week and the treatments were offered to each group every day. There was no difference between the alternative diet and the commercial in daily weight gain, feed conversion, feed efficiency, and productivity indices. According to the economic analysis, of the feed, the best profitability is that of the alternative food. In conclusion, the use of the alternative treatment is viable, once were obtained the same productive parameters than with the commercial food but with a fewer cost.
