Linebreeding of livestock traces to the 1930s when agriculture's success with hybrid corn caught the interest of cattle breeders. The latter is the process of breeding a female for several consecutive estrus cycles. Costs and returns are often difficult to estimate in budget preparation because they are numerous and variable. Most breeders of farm animals as well as commercial producers avoid intense inbreeding for the following reasons: i. Undesirable traits appear with increasing frequency as the intensity of inbreeding increases. Webvary, the method selected also may vary accordingly. With the shrinking of land availability per farm household, it is extremely important that non-crop agriculture and agro-industries are given greater attention. It is one of the systems of out-breeding in which animals of two different species are crossed. Animal Improvement Progeny are less tolerant to adverse environmental conditions. It is good for the traits of high heritability like milk production and growth rate. Inbreeding increases both homozygosity and prepotency (capacity to stamp their characteristics on the offspring) as most of the desirable genes are dominant. The system is an effective way to communicates the achievement status of students to their parents and others. This may be accomplished by consulting your insurance agent or broker. India has a major share in terms of both the number of important buffalo breeds and total population. %qAY'@Y^vPD (K"cC@Ye1 gWn$,6F"t#a{l.aQG[/mKK9 viii. Outbreeding 4. outcrossing 5. Rotational crossbreeding system. The systems are: 1. 2. This program provides protection against the loss of your gross margin (market value of livestock minus feed costs) by using futures prices to determine the expected gross margin and the actual gross margin. 1. \4\+=yD39h,P/~9h# Af@l$^ Hybrid obtained from hybridization have more vigour and resistant but in most cases either they are impotent or sterile and hence are unable to reproduce for the following reasons: 2. Adaptability and heat tolerance. In dominance theory heterosis results from the action and interaction of dominant and recessive genes. However animal breeder claims to have no ill effect in beef cattle.

By following out breeding system i.e., crossbreeding, selective breeding and grading up according to the need, results in improvement in production performance of the crossbred/graded along with improvement in growth rate, reproduction and production. Better adaptability in adverse environmental conditions. You may wish to consider several risk-management strategies for your operation. Pond water should be avoided.

However, inbreeding is intentionally practiced to create genetic uniformity of laboratory stocks and to produce stocks for crossing (animal and plant breeding). But inbreeding is unintentionally generated by keeping small populations for breeding and during selection.
