On 144 gilts from the Landrace breeding herd the effect was examined of the weight gain from birth to mating on the reproduction efficiency. Highly significant influence of daily gain from birth to mating was found on the age and body weight at mating and farrowing (P<0.001), confirmed by respective correlation coefficients (P<0.00l). Even though the gilts with higher growth rate gave more piglets (all, alive and reared), the effect of body weight gain on the number of reared piglets was found significant only at P<0.05. Also the correlation coefficient between the gain and number of piglets weaned was almost null.

The effect of the use of the emulgator Lysoforte was investigated in the 33 days” experiment on piglets. Piglets weaned at the age of 28 days were divided into two groups - experiment (E) and control (C) - 10 piglets in each. In E group Lysoforte was fed as an additive (1 kg/ton) to the commercial mixture ČOS without growth promoters. The live weight and feed consumption were recorded individually. At the end of the first week of the experiment the piglets” faeces were collected during two days to determine the digestibility of dry matter, nitrogenous substances, fibre, fat,organic matter and ash by means of a calculation of the proportion of ash insoluble in HCl. There was no effect of Lysoforte on the daily gain of piglets (C = 339 g, E = 342 g), but the feed intake per kg live weight gain was found lower (C = 1.899, E = 1.770 kg). The digestibility of all proximate feed components was found higher in E piglets - the inter-group difference for dry and organic matter reached approx. 5%, those for ﬁbre, nitrogenous substances and ash from 9.5 to 13.4 %, and 49% for fat. The economic evaluation proved the return of increased expenses per 1 kg of the feeding mixture by adding Lysoforte from 14.40 to 14.60 CZK/kg. The cost of feed per 1 kg live weight gain was reduced by 5.5% (C = 27.346, E = 25.842 CZK).
