Abstract

The experiment was conducted at the Center for Guinea Pig Production, National University of Huancavelica in order to evaluate the use of four levels (0, 25, 50 and 75%) of hydroponic barley (CH) in substitution of alfalfa in the feeding male and female guinea pigs of Peru line, in the growth phase, in number of 72, with 18 days of age and 175 g of initial PV means confined for 42 days. Isoproteic the experimental diets were offered ad libitum to the animals and divided in to two portions (8 and 17 h). It was used the completely randomized design and treatments distributed in factorial scheme 2x4 (sex x levels hydroponic barley) with three replicates per treatment, each experimental unit consists of three guinea pigs. Linear reduction existed for males MS consumption in g / g / day kg 0.75 with increasing substitution levels, this behavior was also verified for PC consumption (g / day). There was a cubic effect for consumption by the female guinea pigs PC in g / day, in g / kg0.75 and in % PV. The substitution of CH alfalfa affected by feed conversion, whose behavior was quadratic and cubic for males and females, respectively. The CH influenced cubical on final weight and daily weight gain in male and female guinea pigs. We conclude that it is possible to replace the CH alfalfa to the level of 75% in female guinea pigs. The level of 25% substitution provides the best weight gain and final weights in males and females growing guinea pigs, which shows the positive effect of the inclusion of CH in the ration of growing guinea pigs.
