Straight-line fattening is a better way for fattening pigs. With this mode of production, we must pay attention to 7 levels.
1. The breeding of piglets will not cover the purchase of piglets in the affected area. After the purchase of piglets in the non-epidemic area, they should also be observed in isolation, and immunizations such as swine fever, edema, lung diseases, and erysipelas should be performed in phases. At the same time do a good job of deworming, gastric lavage, stomach and other preparations. It is best for piglets to breed themselves and reduce the introduction of diseases. Houses, feeding troughs, etc. must be thoroughly disinfected. Deworming: The piglets were dewormed on the first day of introduction. Normally, they were dewormed with "worm insects" at 8 o'clock in the evening and half a pack of 10 kilograms of weight piglets were used. They were retransmitted at intervals of 7 days. Gastric lavage: Stomach washing with small soda, 10 grams per piglet, 15 grams or more with 15 grams, can only feed 1 time. Jianwei: The first 5 to 6 days with a large yellow powder mix, 10 kg 10 grams of pigs, 15 kg can be used with 15 grams.
2. Varieties of 3-4 yuan cross-breeding pigs concentrate the quality of 3-4 excellent pigs, and the breeding effect of hybrid offspring is outstanding. For example, local, Yorkshire, Landrace, Duroc and other breeds hybridize, their offspring grow fast, consume less material, have higher feed returns, and have good economic returns. Compared with unhybridized pigs, the difference in body weight is about 25 kg in 4 months. At the same time, we must choose piglets that are healthy and are basically the same size. They are generally slaughtered in 4 months and can weigh up to 110-120 kilograms. If the growth time of the extended feeding time becomes slower, the feed reward will decrease.
3. Choosing feeds feeds different types of feed at different stages of growth. The straight-line fattening is divided into 3 stages. The piglets are slaughtered to 30 kg for the first stage. The ratio of the piglet concentrates is 25%, that is, the feed fines 25% + corn 60% + wheat bran 15%. 30 to 80 kg for the second stage, with 20% with 40% to 41% of protein material ratio, that is, feed 20% + corn 55% + wheat bran 25%. 80 to 120 kg for the third stage, with 15% of the protein content of 38% to 40% of the protein mix ratio, namely feed fine 15% + corn 55% + wheat bran 30%. If no wheat bran can be used instead of corn, that is, the first phase feed 25% + corn 75%, the second phase feed 20% + corn 80%, the third phase feed 15% + corn 85%.
4. Carefully feed off the feed after a good dry feed, feed the dry material benefits are easy, winter is not frozen, summer is not sour, the pig secretes a lot of saliva after eating dry material, beneficial feed digestion and absorption, but also feed wet material (material, Water ratio 1:1), after 4 hours feeding in winter water seasoning and 2 hours in summer, the advantage is that the feed intake increases, water-soluble vitamins are easily absorbed, and this method can be used when the pig feed intake is reduced. Stage 1 is fed at 5% to 6% of body weight; Stage 2 is at 4% to 5% of body weight, and Stage 3 is at 3% to 4% of body weight. The above feeding amount can be freely eaten and the amount of feed can be limited, feeding 8 to 90% full daily. Feed 4 times a day for the first time 7:00, the second time 11:00, the third time 4:00, and the fourth time: 9:00 PM.
5. It is best to have an automatic drinker to allow the pig to drink water freely, and feed water immediately after feeding to allow the pig to drink enough. Drink cool water and heatstroke in summer, warm water (35°C～45°C) in winter to reduce physical energy consumption.
6. The feed additives related to the first phase to feed selenium-containing trace element additives, promote bone growth, while adding water swelling drugs, the second phase of adding long-acting micromycin powder, to prevent blood bugs and enteritis, reduced feed intake can be added Jianwei San; The third stage adds amino acid additives to promote feed synthesis and meet the need for growth.
7. Keeping temperature off and winter low temperature affecting the growth and fattening effect of pigs, raising pigs in greenhouses can improve the feeding environment and raise the breeding efficiency. The grass shed on the warm shed should be covered, and the air holes should be protected from moisture, and the bedding should be changed frequently. The urine should be removed in time and toxic gas should be discharged (60 minutes per day at noon).
