Resumo

Zinc is an essential nutrient involved in a wide range of biological functions, particularly in aspects of reproduction, including fertility and sex hormone production. The aim of the present study was to evaluate different amounts and types of Zn on ejaculate collection time and training behaviour of young boars. Were used fifteen young males (York-Landrace), 6.8-months-old with 120 Kg body weight (BW) were randomly assigned to three treatments. Boars received a basal diet (BD=T1) corn-soybean without addition of Zn. The BD were supplemented according to their required concentrations in each treatment (T2=BD+ZnSO4 150ppm and T3=BD+ZnMET 150ppm). The boars were trained 30 min per day to mount and mate dummy in a special pen for four weeks. The reaction time and duration of ejaculation were measured, finding that there was no effect (P>0.05) between the observed sexual behavior variables (NTS = Number of training session; FM=Number false mounts (mounting dummy but dismounting before allowing a collection of semen); EM=Effective mounts (mounting dummy and complete collection of semen); DE=Duration of ejaculation in minutes. Treatment x Time interaction (P>0.064) in the variable NTS, decreased when using ZnMET 150ppm with respect to ZnSO4 150ppm, in addition to increasing the Interval between training (days); (P=0.013), also a longer DE (6.49min). It can be concluded, that the results of our experiment demonstrate a positive effect when using ZnMET 150ppm on sexual behavior and some variables assessed during training boars.
