Summary. Results of pilot studies on studying of influence of a humic preparation are given in article Lignogumata-KD-A on efficiency of sows and the pigs received from them. In the conditions of pig factory farm «Orenburg bacon» four groups the of sows of breed Yorkshire up to 10 heads in everyone were created. Animals of control group were on an economic diet and a preparation didn’t receive. To sows of the first skilled group in 2 months prior to a farrow fed Lignogumat-KD-A in a dose of 10 mg/kg of live weight within 10 days with a 10-day break. Animal of the second and third skilled groups a preparation fed according to the similar scheme in doses of 20 and 30 mg/kg respectively. At an assessment of live mass of pigs at the birth it is established that the maximum indicators of a krupnoplodnost are recorded in the second and third skilled groups. On the mass of a nest at the birth of pigs the superiority was on the party of sows to whom fed Lignogumat-KD-A. The mass of a nest at animal skilled groups exceeded control values on 3,54; 12,41 (р < 0,05) and 8,95% respectively. Under the influence of a humic preparation the molochnost of pigs of skilled groups was authentically above, than at control analogs for 0,29-1,86% (р < 0,05-0,01). At depriving at 23-day age the live mass of the pigs who were born from sows to whom fed Lignogumat-KD-A for 1,66-8,28% (р < 0,05) I was higher, than at pigs from control group. The average daily gain of live weight was more control values for 1,57-8,46% (р < 0,05). Lignogumat-KD-A promoted the best safety of pigs which in the second and third skilled groups made 96,6-96,8 against 95,9% in control group and 95,3% in the first skilled group. Increase of reproductive ability of sows and efficiency of pigs it is directly connected with improvement of a chemical composition of milk of pigs. So, the content of fat in milk of sows of skilled groups made 5,60-5,80%, in control – 5,57%. Quantitative protein content increased from 6,17% – in control to 6,20-6,57% – in experience. These distinctions at animals of the second and third skilled groups are especially noticeable.
