Efecto de bioaditivos en indicadores bioproductivos de cobayas (Cavia porcellus) nulíparas y sus crías

Abstract

Objective. evaluate the effect of bioadditives on the bioproductive indicators of nulliparous guinea pigs (Cavia porcellus) and their offspring. Materials and methods. A total of 40 improved nulliparous guinea pigs, 125 days old, 1450 g live weight, were used, divided into four groups of 10 guinea pigs each. T1, Control (basal diet without additive); T2, bioadditive with Lactobacillus acidophilus. T3, bioadditive with Kluyveromyces fragilis and T4, bioadditive with L. acidophillus and K. fragilis. A completely randomized design was used where weight gain during pregnancy, age at first delivery, percentage of fertility, conception index, health, and values of hemoglobin, hematocrit and mean corpuscular volume were evaluated. Results. In animals that consumed bioadditive T4, weight gain during pregnancy was greater (p<0.05); the age at first delivery was reduced (p<0.05); the fertility percentage and the conception index were better (p<0.05) and the occurrence of diarrhea was lower (p<0.05) in the T4 group. Hematological values improved in all groups that consumed biopreparations. Conclusions. The additives with L. acidophilus and K. fragilis improved the productive and reproductive indicators in primiparous guinea pigs. In addition, it intervenes in the improvement of health and hematological values.
