When building a pigsty, we should pay attention to the simplicity of the pigsty. Don't make the pigsty too luxurious, just keep warm and ventilated. Slaughtering should be timely.
For example, the weight of binary pig reaches 70 kg, the inner ternary is 80 ~ 85 kg, the outer ternary is 95 kg, and the British PIC pig 105 kg is the timely weight for slaughter.
In addition, when the pig market price is high, the heavier the weight, the better; When the price is low, it's best to be light, so as to reduce feed consumption and cost.
Extended data:
In rural areas, many pig farmers have the habit of feeding cooked food, thinking that cooked food feeding can reduce feed, soften crude fiber, make pigs eat more and improve digestibility.
According to experiments, there are differences between raw feed and cooked feed in different feed types. Green feed and coarse feed are better than raw feed, and the digestibility of dry matter and carbohydrate in clinker group is also higher, but there is no significant difference between protein and crude fiber.
In concentrated diet, it is better to feed cooked soybean seeds than raw soybean seeds. However, in most concentrate diets, raw feed is better than cooked feed. Generally, cooked concentrate loses 5% ~ 10% of nutrients, and the average daily gain of pigs fed with raw materials is higher than that of clinker 10%.
The concentrate can be saved by 0.2 ~ 0.3 kg per kg gross weight, and there is no difference in dry matter digestibility between them. The protein digestibility of raw feed is higher than that of cooked feed. In addition, feeding pigs with raw materials can save a lot of labor and fuel. However, some toxic or easily polluted feeds, such as rapeseed cake, cottonseed cake, swill, etc., can play a role in detoxification or disinfection after cooking.
