On June 22, this article was published in the article “The cost or increase in the sale of self-produced banned feeds for breeding”. Many farmers came to inquire: What aspects should the farmers pay attention to when using self-made feed? How to supervise the distribution of self-mixed feeds? The reporter visited the experts of the relevant departments.

Self-mixed feeds have advantages and disadvantages

Professor Zhou Ming of the Annunci College of Animal Science and Technology told the reporter that self-made feeds generally refer to 4% to 5% of the premix purchased by the farm, plus energy feed and protein feed, and feed the animals directly. Feeding feeds on farms can help develop local feed resources, especially non-commercial feed resources; it can also save on feed costs and thus reduce the cost of farming.

Ji Xuefeng, secretary-general of the Provincial Feed Industry Association, said that self-provisioned feed can be effectively configured for animal growth and health conditions on specific farms, and can improve feed conversion rates. However, self-mixing also has many shortcomings: Self-produced feed can not guarantee the abuse of additives by some farmers and enterprises; it can not prevent some farmers from adding additional banned substances, such as "lean meat" and melamine; there is no strict inspection procedure for self-mixed feeds. The quality is not stable and nutrition is not comprehensive, resulting in decreased animal immunity.

Scientifically formulated ingredients

Professor Zhou Ming of the Annong University of Animal Science and Technology said that farmers should pay attention to the following points when using self-contained feed:

First, we must ensure the quality of raw materials. In the purchase of raw materials, we must pay attention to quality, we should fully understand the source of raw materials, origin, storage and other conditions. Do not buy adulterated or inferior raw materials because of cheap or convenient prices, and strive to keep raw materials fresh and sanitary and ensure the quality of raw materials.

Second, we must pay attention to the scientific nature of the formula. Compound feed is not simply a mixture of several raw materials, but based on different livestock and poultry species, the nutrition of different feeding stages needs to be formulated with the feed should be adjusted with the type of raw materials, feeding methods, seasonal temperatures, production levels, etc. It must not be changed or used by one party. It is not possible to use cow feed to feed pigs, pig feed to feed chickens, or layer feeds to feed broilers.

Third, pay attention to the reasonable ratio of additives. Under the premise of ensuring protein and energy, attention should be paid to the addition of trace elements such as vitamins A, D, E, and C, calcium, phosphorus, iron, manganese, and zinc. Salt, in particular, plays an extremely important role in mediating the acid-base balance of livestock and poultry and maintaining the osmotic pressure balance between somatic cells and blood. If the salt in the feed is insufficient, the appetite of the livestock and poultry may be reduced, the coat may be rough, the growth may be slow, and there may be unpleasant phenomena such as different foods, wall waste, etc.

Regulation will be more severe

The relevant person in charge of the Provincial Animal Husbandry Bureau stated that the next step is to actively promote the new regulations throughout the province. Once it discovers the behavior of selling self-ingredients, it will seize products, seal up places, and impose economic penalties. It is also hoped that the majority of farmers will actively report This behavior ensures the safe use of feed. In response to the practice of some large-scale farming enterprises selling feed to franchisees, Ji Xuefeng said that it is recommended that enterprises should take the lead in establishing cooperatives to provide feed to franchise farmers through cooperatives.
