If the chef is cooking for humans, then as an animal nutritionist, it is to cook for the animals. People can feel good or bad. Because you know it at a taste, you can vote with your feet. If you don't do well, I won't come to eat! This is why some hotels have a lot of doors, and some hotels have customers.
Animals can also feel the quality of the feed, but unfortunately it does not speak, and is circled, can not vote with the feet, can only silently protest! "The feed is not good, I will not Give you more meat, more eggs, more milk. See what you do? Anyway, the loss is the farm owner."
As a senior animal nutritionist, the author has found that the traditional commercial feed has been difficult to meet the needs of large-scale pig farms during the long-term process of positioning, design, quality control, production and technical services of commercial feed. . There are two reasons.
1. Traditional commercial feeds are not designed according to the nutritional needs of pigs, but are designed according to people's needs or market needs. It is also famous for its market research and product positioning.
For example, we want to design a 4% piglet premix. The formulator and the general manager of the company must first visit the market together to see what price pre-mixed piglets are sold in the market. Results After a period of market research and discussion, it was found that the 6,000 yuan/ton premix market was the most acceptable, requiring formulators to design a pig premix with a terminal sales price of no more than 6,000 yuan. In general, the distribution of 4% pig premix in large enterprises is about 2,000 yuan. If the profit of the dealer is 1000 yuan, the formulator is required to design a 4% premix with a formula cost of about 3,000 yuan. As for whether this premix can meet the nutritional needs of pigs? To be honest, it is basically possible when the price of feed ingredients is not high. But sometimes the price of feed ingredients rises (such as amino acids, vitamins and calcium hydrogen phosphate), it is difficult to meet the nutritional needs of pigs, which is the main reason why the terminal farm often finds which feed is not satisfied.
Second, the traditional commercial feed is a large pot of rice, it is difficult to meet the individual needs of large-scale pig farms.
As a commercial feed mill, for the convenience of production, management and marketing, only a few feeds are often designed. Taking pig feed as an example, some large feed enterprises explicitly require no more than 10 materials. The 10 feeds mainly include the teaching materials, pre-conservation materials, post-conservation materials, piglet feed, growing pig feed, large pig feed, pregnancy feed, breastfeeding material and gilt feed. And these 10 materials are generally sold throughout the province. That is, regardless of the breed, the season, and the health of the farm, the same feed is used.
As a common knowledge of farming, we all know that the variety of pigs is different, and the demand for nutrition is different. For example, the nutritional needs of Dan and American pigs are different, and the nutritional needs of Yang Sanyuan and Inner Sanyuan are different. Dan sows generally have a large number of litters and poor resistance to stress. In order to ensure the lactation ability of Dan pigs, Dan sows should be given higher energy, richer amino acids (especially proline), more vitamins, and vitamin C and other anti-stress. additive. As a US sow, the number of litters is not so much, and the resistance is better, so it does not require such high energy, amino acids and vitamins. Similarly, due to its fast growth rate and low feed to meat ratio, Yang Sanyuan often has poor resistance to stress and needs to be given higher energy and protein, and at the same time should improve its immunity. The internal ternary growth rate is relatively slow, and the feed-to-meat ratio is higher, but the advantage is that it is good to raise. Generally, it does not need to give such high energy and protein. In order to reduce the feed cost, more fiber materials should be given.
In the same way, the feed intake of pigs in summer will be reduced (generally by more than 10%), and pigs should increase energy, amino acids and vitamins by more than 10% as long as they want to achieve the same growth rate. However, if the feed of most feed enterprises does not have problems, the formula will remain unchanged throughout the year. The reason is not that the formulator does not want to adjust according to the season, but can't adjust it. Because once the formula is adjusted, the cost of the feed has to be increased. For example, summer formulators want to add more oil to the feed, raise the amino acid, and add more vitamins. Generally, the formula cost of the full price should be increased by at least 50-100 yuan/ton, and 4% premix will increase by at least 200-300. Yuan / ton. Since the terminal sales price of the feed cannot be adjusted according to the season, no one pays for this fee. Feed companies certainly don't want to lose money and make less money, which makes the formulator know that they should adjust according to the season and can't adjust.
Also in the breeding scene, the health of the herd seems to be irrelevant to the feed. According to the national standards of Danish pigs, when the health of the herd is not good, the amount of protein should generally be reduced. It is recommended that the content of crude protein be reduced by 1% to 2% (interested readers can check it themselves). Animals and people are the same. If a child has a cold, has no appetite, and does not want to eat, the mother usually gives some porridge or noodles. At this time, the big fish will not be given because it cannot be eaten at all. The same is true for animals. When animals are uncomfortable, they should give more glucose, vitamins, electrolytes and antibiotics than humans, instead of giving so many indigestible corn and soybean meal.
Since commercial feeds are faced by thousands of households, they may not be able to take care of that much. It cannot be adjusted according to the variety of pig farms, the seasons, and the health of the pigs. Generally speaking, the commercial feed is a big pot of rice, which is where you are, anyway, this is the meal, it is this taste, you love to eat or not, eat well, you can do it yourself!
Today, China's pig industry is rapidly becoming larger and larger. Today, the whole society is calling for the spirit of artisans. Today, with the gradual refinement of feeding management, the feed preparation methods and management methods are bound to change. Only in this way can the development of the animal husbandry industry be promoted.
