Although four natural mating methods are used, flock or mass mating is the one most commonly employed. 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. (in birds and mammals) the behavioural process of pair-formation rather than of copulation leading to sexual reproduction. Also, a strong supporter of sustainable farming practices. That is; mating does not expect an offspring all the time while breeding is done with the intention of obtaining an offspring. Disadvantages of mating disruption. As rams will have to search for and mate a large number of ewes repeatedly, optimal semen reserves and energy will be required, and as feeding time will be restricted, it is deemed absolutely necessary that supplementary concentrates or a complete ration should be given for at least three, but preferably 6 to 8 weeks before mating commences. If hand mated, your boars can usually breed more sows in a given length of time. Detailed Studies were taken upon genetics and nutrition. You should consider some of the advantages and disadvantages of following either a hand-mating or pasture-mating program. PSYCHOLOGICAL TOPICS 15 (2006), 2, 239-260 243 Not all mating, however, lasts a long time. Therefore, this is the key difference between mating and breeding.

Natural mating does not require skilled personnel while artificial insemination requires skilled personnel. Mating systems as well as the factors that determine them are diverse among crustaceans. As it is generally agreed that improved conditions before and during mating is most conducive to fertility, flush feeding for a period of 3 weeks before mating should be introduced. Previous: State two differences between heat and temperature. It is a way for him to naturally earn more income each year as he can breed specific characteristics into animals and plants to make them produce more over generations in the future, which is good for business. 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. Animals are allowed to mate for the first time when they reach sexual maturity: stallions and mares at the age of three years, bulls and cows at 15 to 18 months, rams and ewes at 12 to 18 months, and boars and sows at ten to 12 months. Since these animals are also kept and bred under controlled circumstances, reproduction has become an economical consideration far beyond the level required for the survival of a particular breed. Advantages and disadvantages of sexual and asexual reproduction. The breeding season is therefore short, but is characterised by fairly regular occurrence of oestrus. This will be the case even if the February mating period is limited to the same extent as the April mating period. Cathy Dwyer, in Advances in Sheep Welfare, 2017. Answers.
