Evaluating the effect of a mineral supplement on the seminal quality of adult boars

Abstract

It was evaluated the addition effect of different concentrations of a mineral supplement, on the seminal characteristics of boars. The essay was developed in Sincelejo municipality. The experiment consisted in three cycles of mineral supplementation, where was supplied 10, 20 and 30 g/day daily in every pig, per cycle. Every cycle had a duration of 55 days, obtaining 1 ejaculate/pig/week (10 ejaculates/cycle). The seminal collects where taken making use of the hand gloved method. After the collect where made, the semen was transported to the laboratory, where it was processed and realized its respective evaluation of seminal quality (macroscopic and microscopic variables). The results evidenced that seminal volume, spermatic motility (individual, progressive), spermatic morphology (tails) and spermatic vitality, showed probability values associated to a lineal effect (P0,05). Finally, it was evidenced an effect of the supplementation levels on seminal aspect, but neither pH nor seminal color (P>0,05). It can be concluded that dietary micromineral supplementation favors some seminal variables such as volume and concentration, maintaining the others characteristics, within normal parameters.
