How to shorten the time for fattening pigs to go out? Method for shortening the time of fattening pigs
In the rural areas, most pig farmers want to grow their own pigs with fast meat and fast delivery, which will increase the efficiency of making money. The following small series takes everyone to understand the influencing factors of the fattening pigs' time and the strategy of shortening the fattening pigs' time.
1 Factors affecting the time of fattening pigs
1.1 variety
The growth rate and production performance of pigs have a direct relationship with the varieties. Under the same feeding and management conditions, the growth and development speed of the improved pigs is fast, the daily gain is high, the fattening period is short, and the slaughtering time is short. Local breeds of pigs are relatively slower. Some farms did not carry out scientific planning when they were introduced. Blind introduction will bring a series of adverse effects to pig production, such as poor vitality, slow growth, low daily gain, poor pork quality, etc. This will result in a slower rate of weight gain in finishing pigs, resulting in a decline in economic efficiency.
1.2 nutrition
Nutritional factors are the main factors for the extension of fattening pigs. In the fattening stage, the poor quality of the feed, the incomplete nutrition, the uneven nutrition, the low digestibility of the feed, the lack of nutrition, and the poor palatability of the feed will make the finishing pigs unable to reach the weight of the slaughter at the time of slaughter. Prolonged. For example, the long-term lack of protein in the feed, the unreasonable proportion of calcium and phosphorus in the feed, the lack of trace elements, and the lack of vitamins may cause the pigs to be malnourished due to the inability to consume sufficient nutrients, and the growth rate is slow. In severe cases, the growth may even stop growing. Or form a stiff pig. Insufficient drinking water will also prolong the pig's slaughter time.
1.3 Management
The management of the pigs is extensive, and the management of the pigs is not enough. It is easy to cause the weak growth of the sows and the suckling pigs, the physical strength is not strong, and the weight gain of the fattening pigs is slowed down, resulting in prolonged fattening time. In addition, poor breeding environment, too high or too low temperature, unsuitable humidity, poor ventilation, excessive concentration of harmful gases in the house, excessive feeding density, etc. will lead to decreased pig comfort, affecting feed intake, leading to nutrients. Insufficient intake. The hygienic cleaning of the pig house is not timely, the disinfection is not thorough, not strict, etc., which will lead to the development of the growing fattening pigs, the poor constitution, the easy infection of the disease and the weight gain, resulting in prolonged slaughtering time.
1.4 diseases
When a pig has a disease, the symptoms often appear are loss of appetite, decreased feed intake, and poor physical fitness. For example, when a pig has a parasitic disease, the parasite will acquire nutrients from the pig body and cause nutrient loss in the pig body. The weight gain will be slowed down, resulting in a decrease in feed conversion rate, resulting in loss of feed and an increase in feed-to-meat ratio. When pigs have parasitic diseases, their disease resistance declines and they are susceptible to other diseases. On the other hand, the reason is that the disinfection of pig farms and pig houses is not strict, the immunization is not carried out according to the immunization program, the vaccine prevention is not taken seriously, and the herd infected with infectious diseases may affect the growth and development of pigs, and even die. .
2 Strategies to shorten the time for finishing pigs
2.1 Scientific introduction and selection
Variety is the main factor affecting the time of the release. Therefore, we must pay attention to scientific introduction when introducing and selecting seeds. At present, there are many varieties of live pigs, and different varieties have their own characteristics. At present, the pig breeds that are fattened in China are mostly binary or ternary hybrid pigs. Studies have shown that binary pigs are more abundant than pure breed pigs. The weight is increased by 15%~20%, and the ternary cross pig is about 25% higher than the pure breed pig. At present, China adopts a binary cross of foreign pigs, such as Dabai and Changbai, which are crossed with Chinese local breeds, or a ternary hybrid obtained by mating of Changbai and Dabai hybrid sows with Duroc boars. The hybrid progeny thus obtained has a fast growth rate, a high feed utilization rate, a good meat quality, and a good fattening effect. When selecting fattening individuals, it is necessary to select pigs with good constitution, firm body structure, well-balanced body, strong bones, healthy and disease-free pigs, and it is required to strictly introduce sick, weak and residual pigs.
2.2 Scientific materials
In the choice of feed, we should pay attention to scientific materials, choose high-quality and efficient feed, and require that the nutrient content and ratio of the selected feed should meet the nutritional needs of pig growth and development, avoid feed nutrient or overnutrition, and feed each. The content of nutrients should be sufficient and the ratio should be reasonable, otherwise it will cause malnutrition in pigs, affecting growth and weight gain. In addition, the quality of the feed should be guaranteed, not feeding the mildewed feed, paying attention to the palatability of the feed, the crude fiber content in the feed should not be too much, can be properly matched with some green and juicy feed to improve the pig's Feed intake. If you choose to use concentrate or premix, you should mix the ingredients according to the formula. You can't mix the feeds at will, so as to meet the nutritional needs of the pigs, and also provide sufficient and clean drinking water for the pigs.
2.3 Scientific Management
To carry out scientific breeding management of pigs, it is first necessary to provide pigs with a comfortable breeding environment, clean up the sanitation, regular disinfection, maintain the proper temperature and relative humidity of the pig house, strengthen ventilation and keep the house. The internal air is fresh. According to the size of the pig, the breeding season and the actual breeding conditions, the breeding density of the pigs is controlled. Only in a suitable environment can the production performance be fully utilized, the feed conversion rate can be improved, and the delivery time can be shortened. In daily management, care should be taken to avoid stress reactions in the herd.
2.4 disease prevention
Do a good job in daily sanitation cleaning and disinfection to kill pathogenic organisms in the environment, and also do immunization work according to the immunization procedures of this field. If necessary, health-care additives can be added to pig feed to prevent disease. The pigs are dewormed before fattening and every spring and autumn to kill parasites inside and outside the body.
The above is all the points for shortening the time for fattening pigs to be referenced by the farmers. Farmers who need it can use the mobile phone to pay attention to the Huiongwang bear's palm, and view the latest agricultural technology anytime, anywhere!
