Effect of bioprepared on the bioproductive behavior of sows and their offspring

Abstract:

Probiotic microorganisms represent a positive effect for porcine production; the inclusion of these bioproducts in adequate amounts acts positively on animal health. The effect of biopreparations on the bioproductive behavior of breeding sows and their offspring. Twelve breeding sows (Landrace / Yorkshire) distributed in three groups of four animals each were used: Control, Bioprepared (T1) and Bioprepared (T2). T1 contained Lactobacillus acidophilus and Streptoccus thermophilus and T2, Saccharomyces cerevisiae and Kluyveromyces fragilis (L-4 UCLV). A completely randomized design was used. It was evaluated: weight gain (WG), birth weight of piglets, average daily gain (ADG), weight loss in lactation (WLL), occurrence of diarrhea in piglets, hemochemistry changes in the last third of gestation and lactation. Birth weight, WG and ADG was higher (P<0.05) in T1 and T2, without variation between them. The WLL was higher in control. The occurrence of diarrhea and deaths was lower (P<0.05) in T1 and T2. The hematochemical profiles were found within the physiological parameters referenced for this species and category. It is concluded that the use of biopreparations in the diet of breeding sows in the gestation-lactation cycle improves the productive parameters; during pregnancy improves WG, while in lactation it reduces weight loss, and in offspring the bioproductive behavior is improved.
