The cost of a sow born a live piglet is actually apportioning the cost of the breeding herd. How to reduce the cost of the birth of a live pig on the breeding pig, we must start from breeding pig breeding management to increase the annual production capacity of fertile sows. The annual production capacity of fertile sows is strong, that is, the number of weaned piglets provided per year is high, the cost per unit of output is low, and the production efficiency is high. On the contrary, each time the weaned piglet is one, it will be the number of sows and boars. The cost of raising the breeding costs to the weaned piglets will increase the cost. Therefore, the production performance of the breeding pigs must be fully utilized, and the production capacity of the breeding pigs must be increased in order to effectively reduce the production costs.
To increase the annual production capacity of fertile sows should start from several aspects:
The first is to reduce the number of non-productive days. Non-productive days refer to the number of days in which sows are neither pregnant nor lactating. It is the most important factor affecting the number of weaned pigs per sow. The most important factor affecting the number of non-productive days is the rate of delivery. The rate of delivery is inversely proportional to the number of non-productive days, the rate of mating and delivery is high, the number of non-productive days is small, and the number of weaned pigs per year is more. Low mating rates are due to conception or pregnancy failure. Therefore, we must strengthen the feeding and management to maintain a good body condition of the sow. We must strictly set the amount of feeding during each stage of pregnancy, and ensure the precision when pursuing the fetus so as to ensure that the birth pig has a sufficiently large primary weight. During the lactation period, it is necessary to maximize sow feed intake, increase lactation capacity, reduce piglet diarrhoea, increase litter weight of weaned piglets, reduce weight loss of sows, and shorten weaning breeding time. Well-worn weaned sows, most of whom had estrus and mating completed within seven days after weaning, often had weaned sows that were in poor condition for more than ten days before estrus. Therefore, we must pay attention to the sow's feeding and management, reduce the weight loss of sows during lactation, and maintain a good body condition, so that they can be estrus after estrus, mating, reduce the rate of anti-acute and miscarriage rate.
The second is to increase the number of live piglets in sows. The first is to improve the quality of boar semen. Feeding boars is very concerned about the environmental temperature, frequency of use, and the useful life. Feeding the right amount of green fodder and driving out the animals every day will help improve boar semen quality. For each semen used for artificial insemination after dilution, the number of effective spermatozoa should be no less than 3.2 billion (usually 80 ml/serving), and the viability should be higher than 0.7; followed by estrus inspection. Weaning sows to drive out boars can effectively detect the estruss of sows and find out the initial time of estrus. The use of boars to check the situation twice a day is one of the breeding systems for each farm.
The third is timely mating, timely mating depends on the timely detection of the situation, sow static reflection can be insemination when breeding, of course, but also in production according to the color of the vulva and mucus, after weaning estrus time and sooner or later The length of time for standing still is flexible. The insemination process should pay special attention to the degree of locking of the scrotum sponge head, the degree of seminal fluid, and the degree of sow standing still.
The fourth is to strengthen the feeding and management, according to the different requirements of each stage, so that fine breeding. Pigs are multi-fowl livestock. To prevent early embryonic death and increase litter size, it is necessary to strengthen the management of feeding, fine feeding, and scientific feeding. During feeding and weaning to estrous stage, the intake of sows should be increased to reduce the weight loss during lactation, promote follicular development of weaned sows, and increase the number of ovulation; during pregnancy, the amount of feed should be strictly controlled according to the different requirements of each stage of pregnancy. , Precise feeding, maintain a good body condition, promote breast development.
Fifth, we must maintain a reasonable gestational age structure for sows.
