A tra ditional straightline breeding pro gram is called purebreeding.
Cattle gutter used for mating.
It is widely used in dairy cattle but is used much less in beef cattle because of handling and labor costs.
Ai has been commercially available for 60 yr.
Cloning could allow breeders to select those cattle that can produce high quality meat or milk and thrive in extreme climates and use them to breed more cattle to be used for food production.
Purebreeding is the mating of two animals registered to the same breed organization.
Mating systems have to do with finding the right genetics but this must be done in the context of the environment into which the cattle are going to be placed.
The induced abortion is uncomplicated the fetus and placenta are usually expelled about 4 or 5 days after the injection and the reproductive tract returns.
If it is a female on sexual maturity it will be mated to another purebred sire of the same breed.
Unwanted pregnancies can be safely and efficiently terminated from one week after mating until about 4 1 2 months of gestation.
Because breeding beef cattle is all about getting cows bred for producing calves to sale either for replacements or beef.
And you don t have to think much about many things such as genetic improvement increasing milk production etc.
Ai offers a selection of bulls with known genetic potential such as measured by estimated breeding values ebvs for traits such as ease of calving or growth rates.
Some common methods of breeding of cattle buffaloes sheep goats pigs horses donkeys mules camels etc.
The same is true of embryo transfer only the effect is multiplied.
Straightline breeding opera tions utilize only one breed.
The ani mals are called purebreds.
Natural breeding and artificial insemination.
In this type of livestock system sires of a pure breed are successively used to mate nondescript females and their progeny generation after generation.
Pregnancies from mis mating and abortion in feedlot heifers.
Breeding beef cattle is relatively easy as compared to breeding dairy cattle.
There are two methods of cattle breeding.
Matching the genetic potential of the herd to the production level of the operation is one of the most critical steps of developing a mating system.
Mature cattle having more than 3 years of age should be used for breeding.
For most commercial operations the inconvenience of concentrating cattle heat detecting and breeding artificially outweigh at least in the minds of commercial producers the advantages of ai.
And cloning when it involves large scale embryo transfer fits the same pattern.
