  Animal Breeding   (Site not responding. Last check: 2007-10-10)
Without written records, there is no certain knowledge of the evolution of animal breeding practices, but written documents dating back more than 4000 years indicate that humans appreciated the significance of family resemblance in mating systems, recognized the dangers of intense inbreeding, and used castration to prevent the reproduction of undesirable males.
Robert Bakewell, an English animal breeder of the 18th century, is considered the founder of systematized animal breeding.
Animal breeding as a modern SCIENCE belongs to the 20th century.

 AllRefer.com - breeding (Genetics And Genetic Engineering) - Encyclopedia
breeding, in agriculture and animal husbandry, propagation of plants and animals by sexual reproduction; usually based on selection of parents with desirable traits to produce improved progeny.
In naturally cross-pollinated or open-pollinated plants, and in animals, loss of vigor in inbred lines can be restored by outbreeding to unrelated or distantly related lines; a first-generation hybrid is more vigorous than either of its purebred parents.
Knowledge of genomes and the techniques of genetics also enhance conventional breeding: In marker-assisted breeding, genetic markers are used to identify the desired characteristics in a plant while it is a seedling, reducing the time needed to select individuals with those traits.

 animal breeding: selected articles from the WORLD ANIMAL REVIEW
The science of animal breeding is concerned with the application of the principles of population genetics to the improvement of domestic animals.
Animal breeding research has been conducted mainly in the structure of land-grant universities under the leadership of professors with responsibilities in research, teaching and, to some extent, extension.
Animal breeding, as an applied field of population genetics, is endowed with a mathematically sound theory developed early in its history.

 NCSU: Animal Science - BREEDING AND KIDDING MANAGEMENT IN THE GOAT HERD
Animals used to detect estrus can be fitted with a harness containing a crayon that will mark the females in heat when they are mounted.
Breeding females should be vaccinated 4 to 6 weeks before kidding, so that some immunity will be passed to their offsprings.
Only first milking from healthy animals should be frozen for later feeding, and the colostrum from older animals that have been on the premises for several years is typically higher in antibody content against endemic pathogens than is colostrum from first fresheners.

 Breeding Minis
I feel one of the best breeding programs a person can have is to breed for exceptional offspring that they will want to retain for their breeding program.
Since the breeder is breeding for themselves, there is no motive to breed "just to sell the babies." Not every foal a breeder breeds will sell instantly, and a responsible breeder must be prepared to care for every animal they breed for the rest of it's life.
Do be careful when breeding for color, as it becomes easier to ignore structural faults in favor of color, which is one of the least important qualities.

 AWIC Newsletter: The Wolf-Dog Hybrid
These animals came to be known in local lore as the "beasts of Gevaudan." After being hunted and killed, it was found that the male weighed about 140 pounds and the female about 110 pounds; these weights were unusually high for the local wolf population.
Their marked aggressiveness and other described physical attributes have led to speculation that these two animals may have been wolf hybrids, perhaps siblings born from the breeding of a wolf with one of the large dog breeds commonly kept by farmers in the region.
Animal control agencies often must rely solely on the word of the owner in determining whether or not an animal is a wolf hybrid.

Increase funding for research into implications of utility patenting on public sector plant and animal breeding as well as the implications of the increase in private expenditures and university “self-financing” on the pursuit of public domain plant and animal breeding.
The face of public plant and animal breeding is quickly changing and in order to reinvigorate public commitment to the discipline an effective campaign to change public policy we must develop a vision and act swiftly and strategically.
Decline in public funding of plant breeding and a rise in private funding has left a hole in education of the next generation of breeders as well as a gap in minor crops and longer term and systems research.

Valuating animal genetic resources: sources of value and comparisons with plant genetic resources The values of unimproved genetic resources can be classified into direct use values, indirect use values, and non-use (or “existence”) values, as shown in Table 2.
For animal genetic resources, it would be reasonable to imagine that the same situation would pertain: there is little incentive for any private firm to engage in extensive pre-breeding, unless there is a way for them to recover the costs of this activity subsequently.
Although animal genetic resources are perhaps more costly to collect and store, and although they appear to be used less directly in breeding, the economics are still striking.

An important part of the idea is that the animal (genotype) can be described in a way that is sufficient for the accurate prediction of its outputs over time.
Feeding behaviour is seen as being the means that the animal uses to attain its intake rather than being the means by which that intake can be predicted.

  Animals that were ranked highest in earlier stages of growth had similar rankings at weaning, which is the usual age were selection or culling decisions are made.
Prediction of additive and nonadditive genetic effects at earlier stages of growth were similar to predictions of genetic effects at weaning, the age at which producers usually make selection or culling decisions.

 G2910 Heritability and Its Use in Animal Breeding, MU Extension
For example, if you are evaluating resemblance between weaning hip heights of cows and their calves, you might make adjustments for differences in age at the time of measurement, age of dam, sex of calf, season of birth, and so forth.
Second, the amount of genetic progress is also dependent on how highly heritable a trait is. Though the parents had an advantage over the herd average of 0.60 pounds per day in gain, they would not have transmitted any of this advantage to their offspring if the trait had a herd heritability.
The general conclusion, then, is that the greater the superiority of the individuals selected for breeding purposes and the higher the heritability of the trait, the more progress will be made in selection.

Because of this, it is no longer a wild animal that can reproduce with no help from man. Some breeds, such as the bulldog, can rarely even breed naturally and must be artificially inseminated.
It does not mean that the animal is not intelligent, can't live a long and productive life or be the most wonderful companion in the world.
The owner should also be prepared to exhibit that animal in show and/or working trials and tests to make sure it is the quality to be bred.

Whether you are breeding cats commercially or simply because you want a litter of kittens from your favorite cat, you'll find that breeding cats can be a fun and rewarding experience.
The act of mating stimulates or induces ovulation; release of the eggs (ova) from the ovaries.
(In other species, ovulation occurs at a set time during estrus, and is stimulated by hormone levels.) For this reason it is not important to time the breeding as long as she is in heat.

As described in the newly approved language of the animal control ordinance, "the (pet) owner who breeds dogs or cats and does not have a current hobby breeder's permit shall pay a litter fee of $25.00 for each litter.
The $25 litter fee is refundable, say the ordinance revisions, once the animal control officer receives proof that the female animal that gave birth to the litter has been sterilized.
The animal control officer is given authority to "enter the vehicle by whatever means is necessary and legal, without being liable to the owner of the vehicle, and take the animal into protective custody."
