Продуктивност на свине майки и ефективност на отглеждане на прасенца при употреба на суха и течна храна.

The article investigated the dependence of sow reproductive qualities, suckling piglet growth intensity, consumption of pre-starter feed and their costs for systems of dry and liquid feeding of piglets in the suckling period. It was found that the use of liquid milk replacer resulted in a 7.5% improvement in the preservation of piglets until weaning, a 7.0% increase in their numbers in the nest at that time, a 16. 7% increase in the intensity of their growth, a 17.0% increase in absolute numbers, an 11.8% increase in the weight of the piglets at weaning and a 19.6% increase in the weight of their nest at that time compared to piglet nests where traditional piglet feeding was used. With the liquid feeding method, piglets consumed 5.3 times more prestarter products per head and 4.4 times more per 1 kg of growth, but 62.0% less dry feed. In liquid feeding of suckling piglets, the number of litters with signs of diarrhoea decreased by 15.09%, and the cost of preventing gastrointestinal diseases increased by 51.8%, for their treatment by 40.4%, and the veterinary cost of raising a piglet in the suckling period by 51.2%, the cost per 1 kg growth of suckling piglets increased by 22.4% due to prevention, by 14.3% due to their treatment, and the total cost of medical and preventive measures by 22.0%. In general, the costs for feeding and medical and preventive measures increased by 170.6% per animal and by 130.7% per 1 kg growth compared to dry feeding. [ABSTRACT FROM AUTHOR]
