Peculiarities of feeding hyperproductive sows during the gestation period


The productivity of a sow is determined primarily by the quantity and quality of the weaned litter received from the sow during a certain period. Practice demonstrates that a properly selected sow feeding strategy maximizes the genetic potential and maintains the health of the animal.

Genetic work aimed at improving the reproductive qualities of sows has led to a change in approaches to animal feeding and the revision of the norms of certain nutrients in the diet.

As a result of breeding sows for hyperproductivity, new production challenges arise: increased nest heterogeneity; reduced viability of piglets; low live weight at birth; intrauterine growth retardation As a result, weaker piglets are born, their mortality rate to weaning increases, and the frequency of neonatal diarrhea development. This consequently affects the growth of the animals in the long term and is manifested by a slowing down of the rate of muscle tissue build-up and damage to the hormonal system. Therefore, if the quality of embryos is not improved at the stage of their development, it will be impossible to increase the main production indicators of piglets in the future.

However, practical experience confirms the possibility of improving the productivity of sows and the quality of nests by nutritional influence on the animals during the piglet stage.
