1. Diversification of diets The growth of pigs requires various nutrients. A single diet is often incomplete and cannot meet the requirements for growth and development of pigs. A variety of feed combinations can use the complementary functions of proteins and other nutrients to increase the digestibility and utilization of nutrients such as proteins. Studies have shown that a single corn feed has a protein utilization rate of 51% and a single meat and bone meal of 41%. If two corns are added together with a bone meal of meat and bone, the protein utilization rate can be increased to 61%.
2, feeding time, quantitative, qualitative time refers to the time and frequency of feeding the pig every day should be fixed, so that not only the law of the pig's life, but also conducive to the secretion of digestive juices, improve pig appetite and feed utilization. The number of feedings should be determined according to the specific feed. In the case of concentrates, feed 2 to 3 times a day, and farms with more roughage will increase 1 or 2 times a day. Summer nights are short and long, during the day, they can be fed once more, winter is short and long, and a night snack should be added. Feeding should be quantified, and do not neglect much, so as not to affect appetite and reduce feed digestibility. According to the appetite and growth stages of the pig, the amount of feed should be adjusted at any time. Each feed should be kept at 89%, so that the pig can maintain a strong appetite at each feeding. The type of feed and fine, coarse, and green ratios must be relatively stable and cannot be changed too much. When the feed is changed, it should be gradually carried out so that the pigs have a habit of adaptation and habits. This will help improve the pig’s appetite and digestion and utilization of feed. rate.
3. After the raw feed is used to feed the pig feed, a considerable part of the vitamin is destroyed. If it is cooked at high temperature for a long time, the protein in the feed will be degenerated and the digestibility will be reduced. Some green and juicy feed may be produced after cooking. Nitrate can easily cause death from pig poisoning. Feeding raw pigs also saves fuel, reduces expenses, and reduces feed costs.
4. Grasp the dilute consistency of the diet The ration of the diet is too dilute not only to affect the secretion of saliva, but also to dilute the gastric juice and affect the digestion of the feed. Feeding the thinners reduces the dry matter intake of pigs, while pigs increase urine output and consume body heat. Therefore, it is better to ration the diet and generally the ratio of water to water is 1:2 to 4. The winter should be thick enough, and the summer can be thinner.
5. Feeding methods Feeding methods can be divided into two types, free-feeding and limited-feeding. Free-feeding is good for daily weight gain, but pigs have more body fat and poor carcass quality. Restricted feeding can increase feed efficiency and lean body weight in pigs, but weight gain is not as fast as free-feeding.
6, feed quality feed quality not only affect the pig's weight gain and feed utilization, but also affect carcass quality. Pigs are monogastric omnivores. The unsaturated fatty acids in the feed are deposited directly on the body fat, making the body fat of pigs soft, which is not conducive to long-term preservation. Therefore, it is necessary to use less unsaturated fatty acids for two months before the hog is released for market. Feed to prevent the production of soft grease.
7, grouping technology should be based on the pig's species, sex, weight and eating conditions for reasonable grouping, in order to ensure the pig's growth and development evenly. When grouping, they generally have the principle of “staying weak but not staying strong†and “joining nights togetherâ€. After breeding for a period of time after grouping, it is necessary to adjust and group them at any time.
8. Tune and sanitation Strengthen the training of pigs from an early age to develop the “three-point positioning†habit, so that pigs eat, sleep and defecate urine fixed, this will not only keep the pigsty clean, but also conducive to pad soil fat , to reduce the labor intensity of the keeper. The pigsty should be cleaned every day and the pig body must be brushed regularly. This will not only help reduce pig disease, but also increase the pig's daily gain and feed utilization.
9, cold and heatstroke temperature is too low, the pig heat to maintain body temperature increased, so that daily weight loss; temperature is too high, pigs decreased appetite, increased metabolism, feed utilization also decreased. Therefore, we must do a good job in summer heatstroke work, increase the amount of drinking water, feed warm food in the winter, if necessary, build a warm circle.
10. After castration, deworming and epidemic prevention of pigs castration, the sexual organs ceased to develop, sexual activity ceased, the pigs performed quietly, appetite increased, assimilation increased, fat deposition capacity increased, and daily gain increased by 7% to 10%. The utilization rate is also improved, and the meat is delicate, delicious, and has no odor. Deworming once before the fattening period can increase weight gain and feed utilization after deworming. In accordance with certain immunization procedures, regular disease prevention work should be carried out. Attention should be paid to epidemic monitoring and timely detection of the disease.
11, to prevent over-exercise fattening pigs and panic-thrilling pigs in the fattening process, should prevent excessive exercise, especially fierce fighting or catch-up, excessive exercise not only consumes energy in the body, but more serious is easy to make the pig suffer from a stress Syndrome, sudden emergence of paralysis, stiff limbs, severe pigs will cause death.
12. The supply of clean drinking water is an indispensable substance that regulates body temperature, digestion and absorption of feed nutrients, and residue excretion. Poor water quality can lead to many pathogens. Therefore, it is necessary to ensure adequate water supply and water quality. In actual production, avoid using thinner materials instead of drinking water, otherwise it will cause unnecessary feed waste.
