First, choose a good manufacturer
1. Construction time, production scale and equipment.
2, product length: professional feed manufacturers long product line, livestock and poultry feed variety. For example, Tangrenshen Company has both full-price feeds for pigs, concentrates, full-price poultry feeds, concentrates, feed for aquatic fish, and so on. Each livestock and poultry breed has different special feed for each growth stage. Unlike some "short and fast" feed mills, only a few profitable pigs use concentrates.
3, no quality control department.
4, after the service staff can solve the actual user problems.
5, raising experts: Some users mistakenly believe that the feed formula will remain unchanged. In fact, due to different batches of raw materials purchased by the feed company, the company's nutrition experts must adjust the formula at any time, and only in this way can we ensure the stability of the quality of the feed.
Second, look at product indicators
1, feeding indicators;
2, using feeding standards;
3, installed, number and so on.
Third, look at feeding results
1. Feces: The darker the stool, the greater the amount of trisulfide added, and the more iron sulfide produced, does not mean that digestion is complete. In fact, normal feces are gray to light yellow, and pig feces are slightly black. Growing and finishing pigs are not necessarily too high copper sulfate.
2, the skin: skin red Mao Liang is a good look, but it can not be over-pursued, the reason everyone can not see the use of know. The red skin indicates that the capillaries are dilated and blood flows to the epidermis, which is detrimental to muscle growth and the actual weight gain is not necessarily good.
3, weight gain: This is the fundamental thing, only to increase weight, the feed can be bought back into cash and become profits.
