THE IMPACT OF MANIPULATION OR REPRODUCTIVE STATE IN THE EWE

THE IMPACT OF MANIPULATION OR REPRODUCTIVE STATE IN THE EWE High image rates in sheep argon a major(ip) focus for direct producers. Management techniques are take on to manipulate the reproductive memory patterns of different breeds so that elevated conception rates can be achieved. The reason at that place has been a need to increase reproduction efficiency is because of the development economic pressures being placed on modern agriculture. This suppuration economic pressure has forced agriculture departments to conduct major enquiry in improving conception rates. This essay was knowing to sample how different breeds of sheep can be manipulated to increase the pistillates reproduction capacity. The breeds were tested for their natural egress of conceptuss and the varying fourth dimensions during the year when ovulation occurs. To manipulate these dickens immoraling(a) traits the sheep were immunised against androstenedione with the hormone regu lin. Regulin is a controlled delivery implant of the pineal hormone melatonin and is thought to influence the reproductive system by effectively changing the season perceived by the animal. A ewe mated in mid summer behaves reproductively as though she is being mated in autumn when ovulation rates are naturally high (Dunstan et al 1988).

The sheep were regularly tested to take up whether this treatment changed the natural reproductive patterns of the merino sheep and hybridize breeds. This experiment is being conducted in the hope that it volition succor primary producers to increase the conception rates in their sheep and manipulate breeding patterns! so that higher weaning rates are developed. These change magnitude weaning rates get out mean that the farming of sheep will continue being a major part of Australian agriculture. The aim of this paper is to examine how treating sheep with regulin will affect the number of embryos expressed by the female and the time that the ewe shows oestrous in the merino and crossbreed breeds. The method that was used in this experiment...If you want to vanquish a full essay, order it on our website: BestEssayCheap.com
