When breeding virgin heifers, it is important to choose bulls that are known to have easy calving. When breeding cows, research what the cow lacks in genetics, is she a high milk producer or have high weaning weights (beef cattle), does she lack conformation. Once you have determined what the dam (mother) lacks, breed her to bulls that will make up for what doesn't have. You want an offspring that will be a better producer than the parents. You should always look for calving ease, weaning and birth weights (the higher the better but not so high it is problematic).
Breeding season for cows and heifers should be from 45 to 90 days long. Sixty days is considered optimum.
You should not consider breeding your Siamese cats on your own but hiring a safe breeder is always an option.
No.
Cows used for breeding only, or cows that are already pregnant.
Yes, breeding cows is considered as animal husbandry.
Some farmers may refer to them as Brood Cows.
Heifers should be bred when they reach 15 months of age. Cows should be rebred 45 to 60 days after calving.
Artificial Insemination or AI.
Breeding dairy cows produces calves which subsequently makes them produce more milk in the next production year. Calves are also raised as replacements (if they are heifers) for the other cows, as these calves have been selected, through the process of sire selection, for giving more milk per year when they mature into cows.
A 20 month-old bull should be able to breed around 10 to 30 cows in a breeding season. The most may be 40, but that could be pushing it.
Selective breeding, selecting for bulls and cows that have better milking ability, breeding those animals together and culling out the cows that have less than average or inferior milking ability. Bulls with less-than-ideal milking ability are not used on such cows.
Typically a ranch's breeding period occurs only once a year. However, some ranches opt to have two breeding seasons a year, with a different herd of cows per breeding season, but using the same bulls for each breeding period. A typical cow should only be bred once to be settled, but if there are more than one bull in the herd at the time, she can be ridden more than once. Bulls, on the other hand, are the more sexually active of the cowherd, and will be very active breeding anywhere from 25 to 50 females in a breeding season.
