The method of dispensing fat feed to broilers

I. types and additions

Fat feed includes animal oil and vegetable oil. The metabolic energy of animal oil such as lard, butter and fish oil is more than 33.5 MJ / kg, while that of vegetable oil such as rapeseed oil, cottonseed oil and corn oil is 29.3 MJ / kg. Generally speaking, the best proportion of fat in the diet of broilers is 0.5% in the early stage and 5% to 6% in the later stage.

Add a method of use

Because the oil is viscous, it should be heated and melted first, then the powder should be added from less to more, mix evenly, dilute gradually, and finally mix well with other parts of the remaining diet. do not mix the oil directly with the additive to prevent it from becoming Joan. Can't mix well. The grease can also be evenly sprayed to the surface of pellet feed with a sprayer. If there are conditions for the production of pellet feed, 30% of the added oil can also be added to the pellet feed, and another 70% can be sprayed on the surface of the pellet, so as to improve palatability.

Problems that should be paid attention to

1. Do not use deteriorated grease.

2. Pay attention to the balance of nutrients in the diet. After the addition of fat, due to the improvement of the energy level in the diet, other nutrients in the feed should also be adjusted accordingly, especially to keep the ratio of protein to energy unchanged.

3. The feeding and storage time should not be too long. Storage time is too long or stored at high temperature is prone to rancidity. Generally speaking, the storage of oily feed should not exceed 7 days in summer and 21 days in winter.

4. Antioxidants should be added to the feed to prevent rancidity.
