TROPICAL GRAINS IN THE FATTENING OF IMPROVED AND SEXED GUINEA PIGS (Cavia porcellus Linnaeus) IN THE AREA FROM LA MANA

Abstract

The investigation of tropical gramineous in guinea pigs in the area of La Mana. The following objectives were pursued: To increase the productive indexes in improved peruvian guinea pigs (Cavia porcellus Linnaeus) under the effect of the consumption of the saboya grass (Panicum maximun Jack), leaves of Corn (Zea mays) and cane of sugar (Saccharum officinarum L) in the area of La Mana, and to determine the profitability of the treatments. 48 improved peruvian guinea pigs separated by sex of 35 days of age were used with a weight average of 305 g. A factorial form 2 (sex) x 3 (gramineous) with four replications was applied, arranged in a (CRBD). For the mean comparisons the Tukey (P≤ 0.05%) test was used. To obtain the profitability of the treatments the Benefit-Cost Relationship was used. The consumption of gramineous (g), consumption of food (g), gain of weight (g), nutritious conversion, live weigh (g) and yield to the channel (%) was evaluated. The male guinea pigs presented the major (P<0.05) consumption of gramineous, gain of weight and alive weight (81.65 g day^-1 of MS; 8.66 g animal^-1 day^-1; 827.7 g, respectively). The gramineous of more consumption (P<0.05) was the saboya grass (99.31 g animal-1 day-1 of MS). However it shows the less efficient (13.82) nutritious conversion (P<0.05). The biggest gain of weight (P<0.05) was registered by the treatment based on leaf of corn (9.16 g animal^-1 day^-1). The yield to the channel (P>0.05) was not affected by the effect of the consumption of gramineous. The biggest profitability was registered by the male guinea pigs fed with leaf of corn + balanced (52.4%).
