"The vitamins in the full-price feed can basically meet the animal's needs. If it is added, it is a waste." Professor Feng Dingyuan of South China Agricultural University expressed disapproval of the blind multi-products of some farmers. The reporter's investigation found that in production, there is indeed a situation in which farmers are privately added for fear of insufficient vitamin supplementation in the feed mill. According to industry sources, the market for vitamins directly to pig farms is large.
Adding vitamins to the farm is very common.
According to the survey, pig farms add vitamins at full price, which is more common in small and medium pig farms. Huang Changfu, a farmer from Zhanjiang City, told reporters that vitamins are often used in his farms, especially in sows before, during and after the sows, mainly to reduce sow stress and to allow the sows to have normal estrus next time. And breeding. “At this stage, all the high-end multi-dimensional 120 yuan/kg is used.†He said that in the nursery and fattening stage, the mid-range multi-dimensional value of 50 yuan/kg is generally used, mainly to increase the feed-to-meat ratio and increase feed conversion. rate.
Yang Yuanzhong, a member of the Yangchun Industry Association and a farmer in the spring town of Lihu, told reporters that although his farm uses the full-price feed of large companies, it still adds extra vitamins, and pigs at all stages are added. He believes that "the vitamin content in the feed is not enough, the additional addition has obvious effects on the estrus of the sow, and the resistance and growth performance of the piglets and finishing pigs."
Huang Zuosen, general manager of Libao Feed Factory in Shunde District, Foshan City, said: The feed mill has taken into account the loss of feed processing, storage and transportation during formulation and production. At present, the full-price feed has reached the NRC (US). Nutritional standards) 2 times or more of the minimum nutritional standard is not only sufficient to meet animal growth needs, but also to improve animal performance. Additional additions are of little significance. “However, this still has a certain gap with the psychological needs of farmers.â€
Zhao Ming, the chief consultant of Consonant International, who was once employed by Roche Vitamins Co., Ltd. (now acquired by DSM), also confirmed that there is indeed a phenomenon of vitamin abuse in farms. In particular, the amount of two fat-soluble vitamins, VA and VD3, is much larger than actual. need.
Experts believe that this is only psychological comfort
The phenomenon of adding extra vitamins to the whole price of pig farms is not considered by many experts. “It will only lead to an increase in costs and economic benefits are not obvious.â€
"In fact, it is a kind of psychological comfort." Feng Dingyuan said that because vitamins have certain anti-stress and immune regulation effects, the current high pig prices also have a certain role in promoting the disease. In order to reduce the incidence of pigs, some farmers would rather pay extra vitamins. .
Zhao Ming said that the current addition of VC and some other auxiliary products such as glucose and minerals to the farm can play some anti-stress and health care functions. As for the promotion of growth, there is no need to waste the cost of adding multi-dimensional products.
In the investigation, the reporter found that many farms did not add or add extra vitamins, and the breeding benefits were good. Qingyuan City Animal Husbandry and Fishery Demonstration Site Liantang Fine Breeding Pig Farm Director is more cautious in this regard. "In addition to daily health care, we rarely take the initiative to add multi-dimensional products." Guangdong Guomao Animal Husbandry Co., Ltd. Deng Guochang said that the current feed The amount of vitamins in the medium is sufficient, and there is very little extra addition. Lei Dongfeng, deputy general of Guangning Guangsanbao Animal Husbandry Co., Ltd. also expressed similar views.
However, some insiders have questioned that this year, vitamins, lysine, phosphorus and calcium and other raw materials have seen a large increase in prices, the first two gains are nearly 50%, and premixes only rose by about 400 yuan / ton this year. . This has to be questioned whether manufacturers have reduced the amount of these raw materials added.
