Abstract: In a relatively short bibliography for nutrition of breeding boars it is represented the limited availability of data on the requirements of this category of pigs to food and their feeding. It is exhibited a correlation between nutritional composition of rations and reproductive performance of male getters. It emphasizes the need of researches for new food additives about which there is an indication to increase the quantity and improve the quality of semen and economic results of pig farms. In such aspect are carried out researches with nutrient additive Vemo Herb T, the results of which are presented in this publication. Vemo Herb T is the dry extract of the herb Tribulus terrestris (Babini zabi) obtained from high quality bio organic plant material - above-ground dry bulk of the plant harvested in the period of massive flowering. General physiological action of the product is determined by its high content of bioactive steroid saponins from fouroethanol type, mainly protodioscine - typical for the herb of Bulgarian region. To determine the effects of the herbal product, in the experiment are include 4 boars of two breeds - Landrace and Tempo (2x2). The scheme of the experiment is based on the principle of consistency - first period (control), all boars get food without added Vemo Herb T - second period (experimental), all boars receive the same compound feed but after 30 daily supplement of Vemo Herb T to ration. The same indexes are controlled during the two periods. It is traced the index “fertility” in sows, as far as resulting offspring - number and body weight of the litter of 80 (2X40) sows , bred by boars in the control and experimental period. The results of a comprehensive research which establish the impact of nutrient additive Vemo Herb T, give grounds to several major conclusions:<br>Vemo Herb T - herbal extract of Tribulus terrestris, is a product with a positive impact on the qualitative and quantitative indicators of semen in boars. This statement is based on the following experimental results: - An increase in the volume of ejaculate by 12.5% (statistically improbable); - An increase in the sperm motility by 7.65% (P <0.001); - An increase in the number of spermatozoa in 1 ml of 11.8%, and in the entire ejaculate by 28.8% (P <0.01); - An increase in the number of doses of semen of an ejaculate by 26% (P <0.01); - The content of sperm in a dose of semen is 5 billion in both periods as a result of provision for dilution. Vemo Herb T positive impacts on the number of offspring in a litter and their body weight of sows, mated by boars, received the herbal supplement. The number of offspring is increased by 3.7% and the average body weight of the litter is higher in 3.9%. The average weight of the piglets remaine the same in both versions of boars feeding. (The differences in these parameters between the control and experimental groups were not statistically significant.) The increased volume of ejaculate and concentration of living sperm cells at including the herbal supplement Vemo Herb T to boars rations, affords relatively more doses of semen by a getter and a corresponding reduction of boars number in the herd (in harmony with the breeding program ) - contributing to business results on a farm; Vemo Herb T can be recommended and implemented as a single supplement or accompanying recovery nekrospermiya with valuable breeding boars; Economic performance of breeding herd in a pig farm is greatly influenced by the quality and quantity of ejaculates. This formulation explains the need and desire to get more and better quality semen of male getters.
