The influence from additives of a vitamin emulsion with L-Carnitin on the sperm qualities of AI-boars

The great demand for semen of top-genetic boars and negative influences on sperm production like individuality, saison and frequent use on few days require possibilities for stimulating and stabilization of sperm production. The vitamin-similar active substance L- Carnitin with its function in the lipid- and cell metabolism supports the energy production in stages of a high metabolic load. Therefore this active substance is very important for the reproduction process, especially for the spermatogenesis at strongly required boars. In present paper the influence of a vitamin emulsion with L-Carnitin on features of the sperm production at AI boars was verified. 15 of 30 included boars of the race Pietrain received a vitamin emulsion with L-Carnitin (Sinta Boar) 4 ml daily over a period of 6 weeks. In this time the daily supplement with L-Carnitin only was 230mg per animal in experimental group. Each boar in the control group without supplement has got only 28mg L-Carnitin per day. The results were as following: A short time after supplementary feeding a significant increase of the volumes of ejaculate by 15,0 % occured. In the control group this is only conducted in a seasonally adjusted way by 7,4 %. Furthermore the sperm concentration with a delay of 3 weeks increased itself significantly around 24,7 % at the animals of the experimental group, on the other hand at the animals of the control group only at 14,7 %. In conclusion the supplement with L-Carnitin-containing vitamin emulsion produced effected caused a significant higher number of total available sperms per ejaculate in AI boars. In comparison to boars in control group the number of marketable semen portions per ejaculate was higher around 13 to 14 %.
