Efecto del propóleo sobre los índices reproductivos y productivos de conejas (Orictolagus cuniculus) en etapa de gestación y lactancia

Abstract

The objective of this investigation was to evaluate the effect of a propolis ethanolic extract (EEP) solution on propylene glycol (PG) (50mg / ml) on the reproductive and productive indices of rabbits during gestation and lactation. The research was conducted at the Oldman's rabbitry farm with 15 16-week-old New Zealand x California hybrid nuliparian rabbits that were randomly divided (taking into account homogeneity of weight) in three experimental groups of 5 rabbits each. . The control group I: (Placebo), group II (EEP 25 mg), group III (EEP 37.5 mg) who received a scheme of three weekly doses orally for 60 days. The results showed no significant differences in the mean daily gain, T0 (14.40 g / d), T1 (15.80 g / d), T2 (17.40 g / d). In the weights at the birth of the kits, there were significant differences for the two groups supplemented with propolis (T1: 552g, T2: 652g), in the weaning weight the difference was significant for the T1 and T2 groups (p = 0.0486). The mortality at birth of the kits did not present differences between groups (4.87% group I, 4.65% group II and 2% in group III). In the behavior of the hematological parameters, the red blood cells showed significant difference (p = 0.0163), likewise the differential of the biochemical profile: Cholesterol showed a decrease for the group I and II groups, (T0 68.42g / dl , T1 57.12 g / dl, T2 57.60 g / dl), in the triglycerides presented significant differences (p = 0.0213), the globulins increased obtaining significant differences (p = 0.0082). Given these results, it is inferred that the incorporation of propolis extract as a natural supplement increases the weight of the kits, preventing diseases by stimulating the formation of globulins and decreasing cholesterol and triglycerides, preventing accumulation of adipose tissue in the mammary glands of the rabbits. increased milk production.
