Abstract

The productive behavior of guinea pigs in the growth - fattening stage was evaluated, when fed with silages of four forage crops, oats and vetch (TI), alfalfa and ryegrass (T2), com leaf (T3), bluegrass (T4). A total of 100 guinea pigs (50 mares and 50 females) weaned at 15 days of age from the improved line were used with five treatments and five replications, applying a Completely Randomized Design (CRD), the size of the experimental unit was two guinea pigs per well. As for the results, the variables final weight, weight gain, carcass weight and carcass yield were not influenced by the treatment on the evaluated parameters, the most efficient guinea pigs were the males and females that consumed blue grass silage (T4), whose conversion was 5.59 with a consumption of 3363. 35 grams of feed in dry matter and a carcass weight of 616.30 grams, the highest feed consumption in dry matter was of the control (T0O with 4908. 11 g, a weight gain of 660.20 grams and carcass yield of 70.97%, The highest mortality occurred in the guinea pigs of T1, T2 and T4 with 2%, and according to the sex of the animal, the females had lower mortality reaching 6%, with an indicator of 1.27, the treatment that consumed blue grass silage (T4) was the most profitable. The silages used in the feeding of guinea pigs in the growth - fattening stage had a positive influence or several parameters presiding over the evaluated profitability, for this reason it is recommended the use of silages in the feeding of guinea pigs in this productive stage.
