PSVI-7 - Effect of substrates of agroindustrial wastes fermented with LAB and yeasts on productive, reproductive and health indicators in primiparous guinea pigs

El objetivo de este estudio fue evaluar el posible efecto probiótico del sustrato de residuos agroindustriales fermentado con BAL y levaduras sobre los indicadores productivos, reproductivos y de salud de cobayas primíparas y su descendencia. Se utilizaron 80 cuyes nulíparas distribuidas en 4 grupos de 20 hembras nulíparas cada uno, de 120 ± 5 días de edad, 1450 ± 25 g de peso vivo, todas sometidas al mismo sistema de manejo y alimentación actual de la granja. Se aplicaron con una dosis de 1 mL del bioaditivo / animal. Los tratamientos suministrados fueron las siguientes variantes: T1. control. T2, Sustrato (residuos agroindustriales) fermentado con L. acidophilus ATCC® 4356 ™. T3, sustrato más Kluyveromyces fragilis L4 (UCLV). T4, sustrato fermentado con microorganismos T2 y T3 .En el experimento se utilizó un diseño completamente al azar, donde se evaluaron los indicadores reproductivos, productivos y de salud. Weight gain in pregnancy was greater (P < 0.05) in T4 in this same group, weight loss was less (P < 0.05) in lactation; the age at first conception and at delivery decreased (P < 0.05) in T4; fertility, the number of live-born animals and the weight at birth and at weaning were higher (P < 0.05) in T4 compared to the other groups; Likewise, blood parameters notably improved in the animals of treatment 4. The treaties with bioaditive were the ones whit the best behavior as reflected in table 1. In the experiment, the beneficial effect as a probiotic was confirmed by the treatments (T2, T3 and T4) of these with the best performance was T4. The inclusion of substrates fermented with LAB and yeasts significantly improves the productive, reproductive and health indicators of primiparous guinea pigs and their offspring.
