INFLUENCE OF A MICROBIAL ADDITIVE ON THE PRODUCTIVE BEHAVIOR OF PREGNANT SOWS, AS WELL AS, HEMATOCHEMICAL AND DIARRHEAL INCIDENCE IN THEIR OFFSPRING

Abstract

The objective of this study was to evaluate the productive behavior in sows, as well as the hematochemical profiles and the incidence of diarrhea in piglets when using a microbial preparation fermented in byproducts of the agroindustry. We used 14 breeding sows, CC21 hybrids (Yorkshire - Landrace/L35 Duroc) and their offspring, divided into two groups: T1, Control and T2, microbial preparation A. T2, contained Lactobacilus acidophilus y Kluyveromyces fragilis L-4 (UCLV). The microbial additive was developed in a substrate composed of molasses, torula yeast and soy milk. 20 ml of microbial preparation were applied to the sows from the last third of gestation until weaning; and the piglets were supplied with 1 ml in mono dose for 2 weeks and subsequently increased to 1.5; 2 and 3 ml per animal respectively. A completely randomized design was used. The productive performance of sows and piglets was evaluated, such as weight gain, average daily gain, feed conversion, protein efficiency ratio, incidence of diarrhea and mortality, and blood profile and blood chemistry. With the use of microbial preparation weight gain, weight gain, average daily gain, feed conversion and protein efficiency ratio varied (P0.05) between treatments (T1 and T2). In conclusion, the use of microbial preparation in the diet of pigs improves the productive parameters, decreases the incidence of diarrhea and blood profiles vary in some cases in the categories studied
