Efecto de bioaditivos en indicadores bioproductivos de cobayas (Cavia porcellus) nulíparas y sus crías
(2022) Miranda Yuquilema, Jose Efrain
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.

With the objective of evaluating the probiotic effect of biopreparations on the productive behavior, zoométricos and the health of pre-weaning piglets. 120 piglets (Duroc / Yorkshire / Landrace) were used, distributed in three groups of 40 animals each, T1 control. T2, L. acidophilus, L. bulgariccus and S. thermophilus and T3 microorganisms of T2 plus S. cerevisiae and K. fragilis (L-4 UCLV). A completely randomized design was used where weight gain, average daily gain, cross elevation, lump height, body length, diarrheal costs and mortality were evaluated. Weight gain and average daily gain; as well as, the elevation to the cross, elevation to the rump and body length was improved (p <0.05) in the animals that consumed the microbial preparations and of these were greater in T3. In all the parameters evaluated at the beginning there was no difference (p <0.05); while at the end of the study in piglets T3 treatment was superior. The incidence of diarrhea was higher (p> 0.05) in the control group. The animals of the groups that consumed the microbial preparations had no deaths during the study. The microbial preparations produced a positive effect on the productive, zoomometric behavior and health of the piglets.
Efecto de un biopreparado probiótico sobre el comportamiento productivo y la salud deternero

The object wasstudy the effect of a biopreparation as probiotic additive in calves was conducted this research.20 animals of Siboney breeding after birth with similar alive weight (32 kg ± 0.23) and size (65 ± 0.8 cm) were selected. Afterward, tow experimental groups (control and experimental) were performed with 10 calves per group. Booth group receive same management and feed, but the experimental group received 20 mL of the biopreparation per calf directly to the mouth twice per week during the first two weeks and afterwards once per week till 90 days of experimentation. The results show to the experimental group with 8.25 kg of weight gain more than (p <0.05) control group. Similarly, the experimental group was taller (2 cm) than control group. In addition, the 70 % of animals in control group presented gastrointestinal diseases, while the experimental group had an increase of 10% of lymphocytes in blood. It was concluded that the biopreparation improved the bio-productive indexes of these animals, as well as increase the economic benefit
Efecto probiótico de bioaditivo obtenido a partir de residuos agroindustriales sobre el comportamiento bioproductivo y cambios histológicos de pollitos

The objective of the study was to evaluate the different doses of bioadditive obtained from agroindustrial residues, on bioproductive behavior and histological changes of chickens (1- 21 days of age). A total of 400 COBB 500 hybrid chickens were used, distributed in four groups of 100 chicks. The doses evaluated were: T1, control; T2, 0.25; T3, 0.35 and T4, 0.50 mL of bioadditive, respectively. The bioadditive is obtained from a mixture of vinegar must and cane molasses with prior treatment, incubated at 37 ° C for 36 hours. Through a completely randomized design, weight gain (GP), feed conversion (CA), occurrence of diarrhea, mortality and histological changes of the chicken intestine with 21 days of age were evaluated. For the histological study, 10 house chickens were sacrificed. The GP in chicks of group T3 and T4 (50 and 80 g) were higher (P <0.0015) compared to the others. As for CA, it was superior in T3 (P <.0001) compared to other treatments. The occurrence of diarrhea and mortality was lower (P <0.05) in all the groups that received treatments, of these the best was in T3; In this same group there was no mortality from 1 to 21 days of age. The size and weight of the intestine was higher (164 cm and 43 g) in T3 (P <0.0001) compared to the other groups under study. The animals that consumed diets containing 0.35 mL of bioadditive (T3), the size of the duodenum, jejunum and ilium was higher (P <0.05). In conclusion, the inclusion of bioadditive with probiotic action obtained from agro-industrial waste improves weight gain, reduction of diarrheal disorders, mortality and intestinal health of the chick (1- 21 days of age) in the critical period of the animal.
Effect of Agroindustrial Waste Substrate Fermented with Lactic Acid Bacteria and Yeast on Changes in the Gut Microbiota of Guinea Pigs
(2024) Taboada Pico, Juan Wualverto
The aim of the study was to evaluate the impact of probiotics obtained from an agroindustrial waste substrate fermented with lactic acid bacteria and/or yeasts on the health and changes in the microbiota of the digestive tract of guinea pigs. Eighty male guinea pigs, Kuri breed, 30 days old and 250 g live weight, were randomly selected and divided into four groups of 20 animals each: T0, control; T1, Lactobacillus acidophilus and L. bulgaricus; T2, Saccharomyces cerevisiae and Kluyveromyces fragilis; and T3. L. acidophilus, L. bulgariccus, S. cerevisiae and K. fragilis. T1, T2 and T3 contained molasses-vinasse substrate in their base, the dose administered was 1.00 mL/animal orally every 3 days. The indicators evaluated were weight gain, occurrence of diarrhea and mortality, macroscopic lesions in the digestive tract organs and changes in the microbiota of the stomach, caecum, small and large intestine. Treatments T1, T2 and T3 improved weight gain (p < 0.05) and reduced the presence of guinea pigs with diarrhea (p < 0.05) and there was no mortality; animals in the control group presented a greater amount (p < 0.05) of macroscopic lesions in the digestive tract organs; in the T1, T2 and T3 groups there was an improvement in the natural microbiota. It is concluded that the inclusion of a microbial additive in young guinea pigs improves intestinal health and consequently improves weight gain, reduces diarrhea and deaths and normalizes the natural microbiota of the gastrointestinal tract.
