The dissertation is scientifically substantiated and experimentally confirmed positive action from the use in feeding of farrowing and lactating of sows, as well as repair and fattening young animals after separation from probiotic feed supplement «PROPIGplv».
It was installed, that the highest reproductive parameters are characterized by sows of the third and fourth groups, which were received an additive in the amount of 4–6 g/day. The multiplicity in these groups was respectively 10,9 piglets per sow, which is 12,3% higher than the control group. The increased level of feed supplement also has a positive effect on the milch of sows, which was at the level of 53,8–53,5 kg, or 26,5–25,8% higher.
The higher milk yield of sows contributed to the intensive growth of piglets in the sucking period, their best conservation, which in general had a positive effect on the mass of the nest at separation at one–day age, which averaged 161,7 kg, or 24,2 kg, exceeded the weight of the control group’s nest, which is confirmed by a higher percentage of 91,5% of the preservation of the young, in the control group 89,6%.
The second scientific and economic experiment was carried out on repair pigs obtained from the same sows according to a similar scheme.
A positive result was obtained regarding the processes of digestion and assimilation of the main nutrients, as well as the functional state in the development of tribal pigs. In particular, digestion of dry, organic matter, raw protein, fat, fiber and BER in animals of experimental groups was higher in comparison with the control group. The assimilation of nitrogen, calcium and phosphorus were also higher. By the functional state of the intensity of growth and development of the animal of experimental groups were prevailed control. Thereby, the obtained results give reason to assert that the dose of 4 g of the head/day of the feed supplement «PROPIGplv» is the most optimal.
The third experiment was conducted simultaneously with the second in four groups of young pigs–analogs for fattening. The amount of feed additives in the structure of combined feed of the experimental groups was accordingly 2, 3 and 4 g of the head/day. Adding to the diet of different amounts of fodder additive, contributed to an increase in average daily increments in experimental groups In order to prevent gastrointestinal disorders, and increasing sow productivity, as well as repair and fattening young animals taking into account the digestibility of nutrients and metabolic processes in the body, it is recommended to use probiotic fodder supplement «PROPIGplv» in rations in the amount which is reflected in the three declarative patents for the invention and technician conditions.
