50 mg per kg of L-carnitine in the forage for nursing sows was introduced and showed how it influenced on the sows reproductive ability, growth and survival of sucking pigs. It was noticed that the sows lost less a live weight during the suckling period and increased their milk productivity and fat, lactose and energy content in milk increase. The sows that received the L-carnitine addition secrete more nutrients and energy with milk. That leads to the increase in the growth rate of sucking pigs during the suckling period by 9,1%, their survival - by 9,2% and the weight of all the survived sucking pigs when they are weaned at the age of 35 days - by 20,1%. The gain in the weight of suckling pigs among the sows, which received the L-carnitine addition, exceeded the one in the control group by 29,1% and made up 57,3 kg. The daily pig gain in the weight in the experimental group was 1,9 kg, which was on 26,7% more that in the control group
