As there is much diversity among the individuals within the breeds and milk yield trait is lowly heritable, the Herd Book scheme under ICAR with emphasis on pedigree production records for important breeds was launched in 1949 to segregate superior animals and multiply. 3. 7. Estrus Synchronization The use of synthetic hormones to make a group of females come into heat at the same time. Linebreeding is a ratchet mechanism for holding any gains already made by selection, while attempting to make further gains. The mules are sterile. Off-springs produced under different environmental conditions show their performance differently. and Cooperation. In the first mating, the F1progeny will get 50 per cent of genes from the purebred sire. Sires of the newly desired breed are continually Mate the rare breed (Breed A) to the common breed (Breed B). It is one of the systems of out-breeding in which pure bred sires are mated with non-descript females and their off-springs for generation after generation. Disclaimer 9. The use of straw in a cold, drafty barn will minimize the need for an elaborate ventilation system, but it will require more labor. This operates in Gujarat and Maharashtra.

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. Specialty markets represent another alternative for slaughter hog producers. Persistency of milk yield. Water requirements for swine are provided in Table 3. Average Yield/Lactation of Different Breeds of Cattle and Buffaloes: Classification of Indian Cattle Breeds According To Utility: Registration of cattle is considered to be one of the essential steps towards the improvement of their economic traits. Farm Houses For Sale In Medina County, Ohio, This system also demands the most capital and labor, and requires a long-term commitment to the swine business. Central unit visits various cattle breeding farms of the Central and State Government, agricultural universities and veterinary/agriculture colleges and registers animals. In recent years there has been increasing interest among small-scale hog producers in using pasture as a feed source. Usually, line breeding is more profitable when relationship is kept high to an outstanding sire than an outstanding dam as the males can produce larger number of progeny. Privacy Policy 8. At least two sires (fathers) are necessary in the herd to practice line breeding system. In subsequent generations, the part of inheritance remaining from the original scrub female will be halved with each crossing. Mating of hybrid with three different breeds in a rotational manner. Therefore when unwanted characters of ancestors appear, such animal is culled from herd to prevent lethal factors in progeny. 4. 2. 4. The decline in requirement, of draught animals has provided same impetus to the diffusion of cattle crossbreeding technology, but it has mainly led to increased rearing of breedable buffaloes to meet the higher demand of milk. that make it an interesting biological phenomenon. Stocking rates depend largely on soil types, the plant species being grazed, and weather conditions. 0000010390 00000 n 4.

Grading up effects rapid improvement through the use of a small number of males of a good breed. A farrow-to-feeder enterprise involves breeding and farrowing sows and then selling the piglets to finishing operations when they weigh 30 to 60 pounds. Alfie Kohn says, grades tend to reduce students interest in the learning itself (Kohn 75). No single blueprint exists for these systems. II. For all practical purposes, a mating can be considered outbreeding system if the individuals involved do not have a common ancestor in the proceeding first four to six generations.

Increases concentration of blood of desired type to obtain better and pure breed animals. Plagiarism Prevention 4. In all grading or breeding up programmes the secret of success is an initial understanding of the genetics involved together with a planned and controlled breeding programme. The actual programme of line breeding can take a variety of forms, from close line breeding of sire to daughter (or son to dam) to very mild type of line breeding. Essentially, the ability to form truckload lots (around 48,000 pounds) of uniform cattle will generally result in even higher prices and open up marketing methods beyond the single-head auction.

But, they have qualities like, adaptability to hot climatic conditions, resistance to many diseases prevalent in the tropical regions (for example Foot and Mouth Disease) and general thriftiness under inferior feeding and management conditions. Advantages Use superior male genetics Faster genetic improvement Frozen semen may be stored and transported around the world Can be less expensive no need to own a sire Safety aggressive males Disadvantages Labor intensive have to monitor heat cycles of females carefully Requires training Decreases genetic diversity Having a balanced ration available will also reduce rooting behavior. First, the buyer and seller know the price and delivery conditions in advance. The objective of grading up is to produce progenies having 50 to 75% of exotic blood followed by inter-breeding and selection to fix desired characters in new breeds containing exotic inheritance between 3/8 and 5/8. 3.
