Pig breeding: pig breeding method and technology, is the cost and profit high

Can you produce commercial pigs like mushrooms?

1. Selecting lean crossbred pigs and making full use of heterosis is one of the main technical measures to improve the fattening effect of meat pigs. In China, binary or ternary hybrids are often used to produce commercial pigs, but the popularization rate still needs to be improved, especially in remote areas.

Second, the appropriate feeding level: the feeding level refers to the total amount of nutrients eaten by pigs day and night. The more the total intake, the higher the feeding level. The level of energy and protein had the greatest influence on the fattening effect of pigs.

Energy level: in the case of a certain level of protein and amino acids, within a certain limit, the more energy intake, the faster weight gain, the higher feed utilization rate, the more fat deposition, the lower the monthly lean meat rate.

Protein level: while considering the protein level, we should also consider the balance and utilization efficiency of amino acids, otherwise it is easy to cause waste.

Crude fiber level: pigs are monogastric animals, the utilization efficiency of crude fiber is low, under certain conditions, appropriate increase can reduce energy intake and increase lean meat percentage. Suggested quantity: piglets less than 4%, fattening period less than 8%, adult pigs up to 10-12%. The utilization rate of crude fiber in pigs varies with breed, dietary digestive energy, protein level, source of crude fiber and so on.

Levels of minerals and vitamins: do not use, do not use too much.

Third, create good environmental conditions

The main results are as follows: 1. Suitable temperature and humidity conditions: temperature is an important factor affecting fattening pigs. If the temperature is suitable, the pigs will grow fast, have high feed efficiency and have good carcass quality. The most suitable temperature and humidity are 20 ℃ and 50%. At a suitable temperature, the effect of humidity is small.

2. Air quality in the house: pay attention to ventilation, prevent the accumulation of toxic gases such as CO2, NH3, H2O and so on caused by excessive density, discharge feces, keep clean and hygienic, have good ventilation, disinfect regularly and strengthen the greening outside the house.

3. Light: the study shows that the effect of light is not very obvious, but strong light can reduce daily gain, carcass is thinner, weak light promotes fat deposition, carcass is fatter.

4. Choose the appropriate fattening mode

1. Rapid fattening (linear fattening method): according to different physiological stages, different nutrition levels and feeding techniques are adopted, a higher nutrition level is used from the beginning to the end, and the energy is appropriately reduced in the later stage to prevent overfattening. The feed formula is divided into two or three stages according to body weight to provide balanced and reasonable nutrition.

2. Feed restriction by stages (hanger): it is a fattening method for pigs under low nutrition level and poor feed conditions. The whole process was divided into three stages: piglet, shelf pig and fattening.

It takes about 5 months for a pig to be born, and the feed is about 220 kilograms. now the feed cost is about 760 yuan.

It takes about 3 months for piglets (about 40 jin) to get out of the column, and now the feed cost is about 640 yuan. (the breeds of pigs vary slightly.) the pigs above range from 195 jin to 220 jin. What is the net profit? That depends on the local pig price.
