Infections: The most vital point of need in the AI program is the detection of the right type of heat and AI at the appropriate time to assure the maximum percentage of conception. Non-random mating is one that occurs with individuals who have a closer relationship. A few good chosen bulls could be raised and maintained well. The incidence of sexual activity, as presented in Fig. Further, the AI made it possible to assess the bull in a very rigid situation and pick up a few outstanding bulls for propagation. Categories: Pets & Animals. As it is usually carried out under direct supervision of each mating, with retesting of ewes after 19 to 21 days, and, as a rule, using rams that have been tested beforehand, high kidding percentages are ensured. It causes infections in cervix and uterus, and puts animals on repeat breeders list AI in post-insemination period should be done after a very careful examination or else one risks infections, early embryo mortality or abortion (this is known to occur when AI is done in the gestational heat).

It is accessible. Termination of oestrus occurs in individual ewes during July, August and finally, at the beginning of September. Investigation on this aspect by Hugo (1955) indicated that the number of ewes exhibiting oestrus reached a peak at the early age of 19 months while the average number of oestrus cycles of the flock showed a gradual increase. Apart from a seasonal influence on ovarian activity as such, there is also conclusive evidence of a seasonal tendency in ovulation rate. With regard to the length of the mating period it should be pointed out that too long a mating and hence kidding period is not desirable from a management and economical point of view.

Over the decades that pheromone pest programs have been used several disadvantages have been argued when compared to the use of conventional pesticides. In biology, mating is the pairing of either opposite-sex or hermaphroditic organisms, usually for the purposes of sexual reproduction.Some definitions limit the term to pairing between animals, while other definitions extend the term to mating in plants and fungi.

As the breeding season of a particular flock is comprised of the seasons of its individual members, it obviously follows that the peak represents the time when the maximum number of ewes in the flock exhibit sexual activity. any reproduction involving two sexes. (recording purposes). The optimum age at which maximal sexual activity (number of cycles per ewe as against the possible maximum) was reached was calculated at 5 years while the maximum length of the breeding season (mean number of oestrus cycles) was attained at 4 to 5 years. Studies suggest that children … Further, to make the utmost use of good quality semen, co-operatives or other organizations came up. The September season furthermore has the advantage that kids are born in warmer weather conditions instead of the cold weather of the July season, when big losses may occur due to adverse weather. It requires no company patent. Research workers reported earlier onset of the breeding and kidding season when ewes were prejoined with vasectomised rams. As the mating season in relation to the natural breeding season is of vital importance in determining the reproduction rate, the selection of mating practices most suitable to a specific set of circumstances remains one of the basic considerations. Power tools and hand tools as categories both have their drawbacks and their strong points. (e) Camps and Camp Sizes - Apart from choosing rested camps for mating, on account of their flushing value, it should always be endeavoured to select the more open type of camps with a more even surface and favourable topography.
