Improved fattening guinea pig (Cavia porcellus L.) based on tropical forage grasses and shrubs in Quevedo, Ecuador

Abstract:

The investigation you executes in the Experimental Property “The María”, property of the State Technical University of Quevedo (UTEQ), located in the kilometer 7 1/2 of the Road Quevedo - The Connection, county of The Ríos whose geographical location of 1º 6’ 13” of south latitude and 79º 29’ 22” of longitude west and to a height of 73 msnm. The investigation had duration of 56 days. The objectives were: to) to Determine the increment of weight in the one puts on weight of guinea pigs in base of gramineous tropical. b) to Determine the increment of weight in the one puts on weight of guinea pigs in base of forrajeras tropical arbustivas. c) to Determine the profitability of the treatments. 48 guinea males pigs were used without of 30 days of age with a weight average of 411.11 g. The experimental unit was conformed by two animals. A design of blocks was applied totally at random (DBCA) with four repetitions. To determine differences among treatment stockings the test of ultiple ranges of Tukey it was applied (P≤0.05). the forage consumption was evaluated (g), I consummate of food (g), I weigh I live (g), gain of weight (g), nutritious conversion, I weigh to the channel (g) and the yield to the channel (%). The profitability determined it to him through the relationship I benefit cost. The biggest forage consumption (P <0.01) I register it the grass saboya and the mulberry (42.49 and 36.46 g MS animal-1 day-1, respectively). The mulberry supply allowed to increase (P <0.01) the alive weight (915.70 g); the gain of weight (9.06 g animal-1 day-1); more efficient nutritious conversion (4.24); I weigh to the channel, yield to the channel and the profitability (639.83 g; 69.87% and 61.64%, respectively). The use of the cucarda in the one puts on weight of improved guinea pigs they affect the main productive indexes of this species significantly.
