Five factors affecting the efficiency of pig raising

How to improve the efficiency of pig raising has always been the most concerned issue for farmers. There are many factors affecting the efficiency of raising pigs, such as pig breeds, feeding management methods, disease prevention and control, and management methods. Foreign experts believe that in terms of technical measures, improved feed accounted for 49%, improved rearing accounted for 26%, improved health level accounted for 10%, and cultivated improved varieties accounted for 15%. Below, we will discuss the measures to improve the efficiency of pig raising from these aspects.

To feed a number of suitable

One problem that is currently overlooked in pig production is that it only focuses on the nutritional level of each liter of feed, not on the daily feed of the diet. Although the diet is formulated in strict accordance with the pig's production performance and nutritional level, the amount of diet fed is often unable to meet or exceed the nutrient requirements of its physiological needs, resulting in adverse consequences: either the pig's feeding period is extended. Cause excessive eating, causing indigestion, disease, and waste of feed. Therefore, on the basis of scientific preparation of diets, we must pay attention to the appropriate feed amount of feed, in order to give full play to the production performance and improve the nutritional value of feed. In general, the daily feed of pigs can be fed at 4% of their body weight. Lean meat pigs weighing more than 60 kg can be fed at 3.5% of body weight. For finishing pigs, it can be determined based on the expected daily gain and expected feed utilization (feed/weight gain).

Two green fodder with a focus on science

Green fodder is a health food with relatively balanced nutrients. They are widely sourced and inexpensive. Generally, 10 kg of green fodder is equivalent to 1 kg of concentrate. According to the relevant data, the ratio of green feed and concentrate in the early stage of growing and finishing pigs is 1:0.3～1:0.5, and the proportion in the later period is 1:0.5～1:0.7. It can save 27.3 kg to 32.7 kg of feed per pig, increase feed utilization by about 10%, and increase profits by 12.6 yuan to 16.20 yuan. It can be seen that the rational use of green fodder in the production of pigs and the rational matching of refined green feed are an important measure to improve the economic benefits of raising pigs. Generally, the ratio of green and feed is 2:1 to 4:1, boar is 1:1 to 2:1, and pigs and commercial pigs are 0.3:1 to 0.5:1 in the early stage. For 0.5:1 to 0.7:1, breeding sows should be 2:1 to 4:1.

Three focus wet mixed raw material fed regular feed and

According to the relevant tests, the utilization rate of general feed cooked feed is about 10% lower than that of raw feed. Therefore, in addition to beans, sweet potatoes and residues to be heat-treated before feeding, other feeds should be mixed with feed water and raw feeding methods to reduce the loss of nutrients and improve feed utilization. At the same time, in the number of feedings, except for piglets 10 weeks old, it is necessary to feed three times to four times a day. It is recommended to adopt the two-day feeding system (but in the late summer and winter, it is recommended to add a meal at night) to reduce the multiple feeding. Feeding stimulating pig movement increases the consumption of physical energy and the waste caused by the spread of feed, thereby improving the efficiency of pig raising.

Four advocate night plus feeding time supper

In winter, the light is short, the temperature is low, the night is long, the weather is cold, and the pig's physical energy consumption is high. Adding night food from 11 pm to 2 pm is conducive to supplementing the consumption of pig energy, resisting cold and promoting growth and development. In the late summer, the temperature is high during the day, the weather is hot, the heat dissipation capacity of the pig body is poor, the relative temperature is low at night, the temperature is cool, and the appetite of the pig is strong. Feeding the pig with a night meal at around zero can supplement the nutritional needs of the pig body and promote growth and development. Therefore, whether it is a cold winter or a hot summer end, feeding the pigs with night meals can significantly improve the breeding efficiency.

Five stresses adequate supply of clean drinking water

Water is a component of all cells in the body and plays an important role in regulating a range of metabolic processes such as body temperature, nutrient operation, digestion, absorption, and waste excretion. The water supply for general pigs is: 16% of body weight at the end of spring and autumn, 23% of body weight at the end of summer, and 10% at the end of winter. Promote your own drinking water to increase weight gain. According to the test, the free drinking water of pigs can increase the weight gain by 15% compared with the daily water supply.
