Abstract
The influence of the age of the first insemination of pigs on their subsequent productivity was evaluated. In the period from 2017 to 2020, 167 pigs were inseminated in the company Plemzavod-Yubileyny in the Tyumen region, which were divided into groups. Productivity indicators were analyzed based on the number of piglets born. In 2017, 12.5 piglets were obtained in group III, where the age of the first insemination was 241-253 days, and 12.7 piglets were obtained in group VI (281-311 days). In 2018, 101 sows were farrowed out of 164 heads (groups I, II, III), 1123 piglets were received from them, 1037 live ones were received. The largest number of piglets born was observed in group IV-12.4 units. In 2019, the largest number of piglets born was observed in group III-11.4 units. In 2020, out of 181 farrowings, 135 units were received, of which 1,528 piglets, of which 1,507.5 live.
Highlights
In providing the population of Russia with meat products, a significant role is assigned to pig breeding as the most intensive and efficient branch of animal husbandry, due to the extremely valuable biological characteristics of these animals: fertility, early maturity, omnivorousness, a wide range of use of slaughter products and their long-term storage.In recent years, the use of sows has increased significantly
The pigs were divided into groups according to the age of the first insemination
There was a positive trend in the percentage of gilts farrowing in 2019-2020. compared to 2017-2018 In 2020, there is a decrease by 8% in violations in the first half of pregnancy
Summary
In providing the population of Russia with meat products, a significant role is assigned to pig breeding as the most intensive and efficient branch of animal husbandry, due to the extremely valuable biological characteristics of these animals: fertility, early maturity, omnivorousness, a wide range of use of slaughter products and their long-term storage.In recent years, the use of sows has increased significantly. It should be noted that the pigs of the I group, inseminated at the age of 217-228 days, had a high rate of born piglets of 11.2 per farrowing.
