Efecto de la utilización de bloques nutricionales a base de harina de maralfalfa en la alimentación de conejos en la etapa de gestación - lactancia.

Abstract

The present investigation was carried out in the Academic and Research Unit in Minor Species of the Faculty of Animal Sciences, where the effect of the use of “maralfalfa”( lucerne) levels (10; 20; 30 %) in the elaboration of blocks was analyzed. For the feeding of rabbits during the gestation-lactation stage to be compared with a control treatment, 40 rabbits of the New Zealand breed with an average weight of 2.89 kg, of 1 year of age, were used. A Completely Random Design was applied with 10 repetitions for each treatment, the Size of the Experimental Unit was 1 animal per cage. The experimental results of the productive and reproductive behavior of the mothers determined highly significant differences (P <0.01), in the variables: fertility and fecundity for T30 treatment and in the variable: prolificacy for the T10 and T20 treatments. While, for the variables: final weight, block consumption, forage and total food consumption did not report significant differences (P> 0.05). According to the productive behavior of the offspring in the variables: size of the bait at birth, size of the bait at weaning, weight of the offspring at weaning, and weight at the time of weaning, no significant differences were reported (P> 0.05). The highest profitability was obtained with the T30 treatment, reaching a benefit / cost of 1.32, which means that for every dollar invested a profit of 32 cents will be obtained. T30 treatment in the feeding of rabbits in the stage of gestation-lactation presented positive responses in the reproductive behavior (fertility, fecundity and prolificacy), it is recommended the use of nutritional blocks with 30% of maralfalfa flour in the feeding of rabbits during this stage.
