support U.S. swine industry is the most advanced animal husbandry sectors. The past decade, the United States in breeding sows,
prada sale 2011, weaning management, and breeding technology has changed dramatically. Currently, the U.S. swine industry in the prevalence of these practices. 1, individual weaning: the heavier the fossa weaning piglets 2-3 days in advance,
prada sneakers, so that the smaller weight piglets have the opportunity to eat more milk, so as to achieve greater weaning weight. According to the research,
prada handbags 2011, weaning weight over 6.5 kg of pig weaning weight than the less than 5 kg, 7 days in advance to market weight.
2, stop feeding law: that is weaned from the sow house directly transferred to the finishing house, and raised to reach market weight. Thereby reducing homes to care homes from the sow part of this tradition, to avoid the resulting pigs have some of the stress response. The main advantage of this method is rapid weight gain, lower labor and transportation costs; disadvantage is that low utilization pig,
prada outlet, can not be done as usual,
cheap prada handbags, Mei Dong Yang finishing round three batches of pigs per year. Finishing one-stop feeding method also requires a better insulation performance homes, the breeder has a higher level of technology.
3, isolated from weaned piglets feeding method: its practice is implemented within 1-2 weeks of age weaned piglets into the field away from the sow conservation breeding farms, to reduce certain disease from sow to piglets vertical transmission. Isolation rearing method can improve the litter size per sow per year the number of columns for each year of litter size litter size, but may be reduced under the litter in the litter size and farrowing rate.
4, co-sow farm: it is the total number of farms growing a breeding sows sows 1200-1600 field. Generally speaking, each sow farm has 8 shareholders,
prada shoes, depending on the piglets stay in the conservation of discounted time. Sows each shareholder to accept the field produced within a week all the piglets. When these pigs leave the nursery after the re-growth of pig farm from the sow another batch in a week to accept the production of all the piglets. Sow the whole field of cooperation in all out style farms an important part of growth. And all in all out style more and more farms are being replaced by way of non-stop playing. This approach will help improve management efficiency and in force between the two groups of pigs a more thorough cleaning and disinfection.
5, the stage of breeding sows law: sows during pregnancy and lactation nutrition consume large amounts of body reserves, mainly fat, protein and minerals. In the early weeks of lactation, the sow's back fat can be reduced by 30%. In order to re-sow in heat must be rapidly re-nutrition reserves. Sows stage feeding method includes at least four kinds of feed: feed late lactation, pre-breeding material, breeding material and the late stage of pregnancy material. After weaning increased by 300 kcal intake per day can raise a litter about. The increase in energy must be in the form of starch. Glucose produced from starch can stimulate ovulation. Organic trace minerals also help recovery of trace elements sow body reserves.
6, to improve market weight: 100 kg market weight has increased to 114 kg. To improve the processing efficiency is willing to slaughter weight to larger farms. Modern breeds can reach a larger accumulation of excessive body weight and not fat.
7, meticulous record: more than 90% of farms have adopted computerized methods of recording. Producers will need to produce records and financial records together.
8, environmental control: the main environmental problems caused by pig is the smell. Odor control measures include: installation of expensive sewage treatment facilities, changes in feed protein and mineral content, the feed material by adding yucca plants or group of additives, enzymes and so on. Many pig farms to take in the legal and moral and responsible attitude to environmental protection.
