Hello, José. I carried out my thesis in handling, it collects, freezing and insemination of swinish semen. We evaluated the fresh semen, the diluted semen and the frozen semen. We evaluated the following parameters: volume in ml, aspect, pH, color, total motilidad, individual motilidad, viability%. In frozen semen we analyzed pre-frozen motilidad to the diluters, motilidad post unfreezing and survival. Each one of these factors valued them with scales put by the work team.
Esperando that he/she has helped you in certain way. I say goodbye.

For Dante,

Feeding

The influence of the nutrition has more than enough els paràmetres reproductius of the verro they are centered mainly in the libido, the spermatic production, the viability and the capacity fecundante of the sperms (a reduction of androgens in the blood, mainly for protein lack).
The influence in the libido has been observed so much in states of malnutrition as in overfed animals.
The production of sperm is affected (diminished), mainly com poor diets in energy and protein, mainly in the young males. The Vitamin AND and the selenium iInfluyen in a decisive way in the maturation of the sperms, favoring the integrity of their membranes, for their actividas cellular antioxidante. The fiber is very important for the satiety sensation (the hogs in general feed a single time a day) that determines a relaxation state and tranquility that he/she is reflected clearly in the production and quality of the semen.
Regarding the capacity l'espermatozoides fecundante, it is not very clear, todaíia the qualitative effect of the nutrition. Anyway, the hygienic qualities of the I think, it seems to be that they have some significant consequences about the motilidad, viability and cellular abnormality. In this sense, for example, the presence of certain micotoxinas (zearalenona, aflatoxina b, etc) they have a negative repercución in the qualitative parameters.
It is always better to make specific feeding programs for the verros, even for animal.
I hope my comments help you.
Sincerely.
