1. Color Color is the first appearance quality trait of commercial feed. Due to the one-sided propaganda of a few manufacturers, misleading feed distributors and farmers have over-emphasized color and demand yellow or golden. The compound feed is mostly corn-soybean meal type, the raw material composition is single, the animal protein feed such as fish meal and the local cheap rapeseed meal are not used or used, and the “complementary complementarity†between the raw materials is not fully reflected. Soy protein accounts for the total formula. The proportion of protein may exceed 60%, and there are disadvantages such as poor quality and easy diarrhea in piglets. It can be properly guided by technical training and breeding demonstrations of farmers to promote the healthy development of pig production. 2. Particle size Piglet feed is generally small pellets. And 40-50% of farmers like to buy piglets to feed and grow pigs, and believe that there is quality assurance. In order to meet the psychological requirements of farmers, some feed production plants produce small amounts of growth and fattening pigs, which inevitably increase production costs. Maintaining a moderate particle size, reducing unnecessary production costs, and improving the intrinsic quality of the product are the most critical. 3. Water time Many farmers are used to soaking granular feed water, then adding a small amount of corn flour, wheat bran, etc. to feed the piglets, or adding green feed and by-products to feed the growing pigs. It is believed that the pellet feed is completely dispersed in the water within 1 minute, and the quality is guaranteed. This is an easy way for farmers to check the quality of the feed, which is inevitable. For example, the ratio of wheat in the formula (lower than corn) is above 8%, and the time to complete divergence in water may exceed 1 minute. The farmers should be patiently explained, and at the same time control the crude fiber content, reduce the amount of fillers such as bentonite, and the fat content is more than 4%. 4. "Red" “The skin is rosy and the hair is bright†can increase the price of pigs, especially for commercial piglets. Some manufacturers blindly use various so-called "ricin" additives, large doses of arsenic preparations, subclinical poisoning doses of copper, etc., in order to improve the appearance of the piglets of commercial piglets, but inevitably cause a certain degree of harm to the environment. Nutritional balance is the most important, and energy (fat content) is the primary factor, especially in autumn and winter, not only to ensure the effective energy concentration of compound feed, but also to maximize the feed intake of pigs. 5. "Black" High copper significantly improves piglet performance while blackening pig manure. Some manufacturers blindly publicize and compare each other. According to the degree of blackening of pig manure, the quality of compound feed is measured, so that the amount of copper added is getting higher and higher (some up to 300mg/kg), and some directly use crystalline copper sulfate. (particles). In addition to high copper, there are still many measures to improve the performance of piglets. To protect the ecological environment, it is recommended that the amount of copper in the piglet stage should be controlled at 125-150 mg/kg, and high copper should not be added in the growth and finishing stage. 6. "Sleeping" Some manufacturers use a large number of inferior feed ingredients to reduce costs. The pigs have low appetite, frequent activities and eating, and affect rest. In order to strengthen the pigs' sleep, banned drugs are added to the feed. Prohibited drugs endanger human health and must be banned and banned. It is the key to improve the nutritional balance and improve the internal quality of products. “Eating-sleeping-long†is a summary of people's long-term pig production. Only by improving the feed intake of pigs and ensuring the effective nutrient concentration in the diet can the problem of “sleeping†of pigs be fundamentally solved. 7. "Do not thin" Piglet diarrhea is a major concern for pig producers. There are many factors that cause diarrhea, mainly nutritional, bacterial, and environmental. From the perspective of nutrition and feeding, it is mainly solved by adding industrial synthetic amino acids to reduce protein levels in the diet, reducing the proportion of antigenic feed, using high-quality animal protein feed, adding organic acids and enzyme preparations, and strengthening feeding management. 8. "Low price" In economically underdeveloped regions, low-price feeds are relatively popular. However, such feeds are added with a large amount of fillers (ç »ç³ , bentonite, etc.), which may cause indigestion and prolong the feeding cycle. It is necessary to advocate "high quality and good price" and make publicity and explanation to the farmers to reduce unnecessary disputes and complaints.
The Phenolic Resinmay be considered to be the first polymeric products produced commercially from simple compounds of low molecular weight, i.e they were the first truly synthetic resin to be exploited.
Phenolic resin has low toxicity. The phenolic resin contain basically p-t-amylphenol, p-t-butylphenol, p-nonylphenol, mixed cresols, and also used cashew nutshell liquid.
