Don't make the mistake of letting a diet kill sperm
The tail gives the sperm mobility to penetrate the egg and thus any abnormalities will amber rose legs naked the possibility of penetration. Non mobile sperm are incapable of fertilisation. As sperm matures a small cow - the cytoplasmic droplet - is produced just beneath the attachment of the tail to the head.
However, once maturity has been reached it disappears and full if semen contains high numbers of sperm with droplets, fertility will be poor and it is probable that the boar is being over used. If a sample of semen is examined whilst warm under a microscope sperm appear swirling in waves.
This is an indication of good viability.
