Sows Should Be How To Manage
Breeding sows to maintain good function, can greatly improve pig production technology index, which is the pig a good economic foundation. I found the service, many farmers sow management of the problems, in this, I would like to conduct exchanges and peer issue.
One sows choice errors
1. Some pig sows in group and diversified: the dual hybrid, crossbred, or even multiple hybridization; this problem caused by one: fattening pigs, she is both high and low, long or short, There are skinny fat. Coat with white, red, black and red. Growth rate is mixed, uneven size; pigs uniformity is poor, I do not sell like, pork price not go up. Second, the unusual heat, the heat’s not heat, estrus expression was not obvious, breeding rate is not high, calving rate, third, production efficiency is poor, the whole group are generally higher than the 0.2:1 feed conversion, daily gain may be reduced from 100 to 200 grams / day.
2. Purchase soon out of sows: Most of these sows are aging, poor manufacturing performance, or kinds of problems; that not only influence the result, there may be the introduction of pathogens, the potential threat is high.
2, sow diet selection mistakes
1. Fattening pigs feed for sows; pigs and fattening pigs in the use of nutritional standards and methods of feeding and management are not the same, which decided to use a dedicated mother to live pig feed, to ensure their normal growth and development and reproductive performance.
2. Since with incomplete feed on nutrition sows, with the increasing intensity of pig breeding on sow nutrition for every stage of increasingly demanding, especially in lactation feed requirements more to the higher, but some farms use a lot of local resources, preparation of sow feed, seek the lowest cost of feed, often caused by nutritional deficiencies, lack of balance of nutrients. Some even fodder and forage (grass) dominated, without or very little increase premix, feed, protein feed and energy.
This is a great influence reproductive performance of sows, some long-term weight loss, reduced service life.
3, sow feeding and management failures
1. Gilts: first, be regarded as finishing pigs, and allowed to feed freely, resulting in sow body fat and even influence the breeding skills; but be regarded as the basis of sows to feed the worst feeding of, resulting in thin sows, growth stunted.
2. Basic sow: First, feed the full feeding, resulting in excess nutrients, fat sow; second is too limited to feeding, resulting in inadequate nutrition, sow thin.
3. Poor sanitation and pig: sow susceptible to skin diseases, due to body water, it is easy through the milk, the body surface will pass to the pig pathogen; the pathogen can also be passed through mating boars.
4. Sow out not in time: Some older, decreased litter size; some heat for long periods, infertility, multiple mating: some genital tract inflammation, infertility treatment and so long continued feeding, not time-out. I have found that about a year, not some pig sows producing one child, still keeping the. Sows as a production machine but not the normal production will inevitably cause the overall decline in production performance and production efficiency.
5. Sow irrational population structure: the structure of normal sows should be the first child and multiple births was relatively small, the first 2? 7 embryo, the proportions of up to 70% of normal. Key to good breeding index. Furthermore, sows and boars should be proportional to the number, usually 25:1; are not to be used boar frequency is too low, affecting reproductive effects.
3. Does not attach importance to prevention work
Little attention in many pig sow prevention work, impact on reproductive harm large number of diseases, such as pseudo-rabies, parvovirus infection, Japanese encephalitis, hog cholera, brucellosis and streptococcal disease virtually no immunization work, not to mention the establishment of a sound monitoring system for epidemic prevention.
4. Measures to improve reproductive performance of sows
1. According to the local epidemic and the introduction of market conditions to establish and improve disease control prevention system, such as disinfected once a week; usually kept clean; specific manner of classical swine fever, pseudorabies, parvovirus, JE, streptococcus and other immune diseases .
I am an expert from China Computer Parts, usually analyzes all kind of industries situation, such as motor start capacitors , run capacitors.
