1、 Different stages of premix should be selected according to the growth status of pigs.
Generally, from seven days after birth to the market, the selection of pig feed, nursery feed, piglet feed, medium pig feed, large pig feed, etc. According to the pregnancy status, sows can choose pregnant sow feed and lactating sow feed, while boars generally use large pig or boar feed. But sometimes different feed varieties can be selected under the guidance of animal husbandry or veterinary doctors.
2、 To judge the quality of feed comprehensively.
1. Judging from the market reaction, whether a certain premix can be complained about, whether it can be stable, and how long it will be on the market. The earlier the normal time is, the better feed is the more stable or developing trend in the market.
2. From the strength of feed manufacturers and after-sales service status, the selected feed is stable for ordinary strong manufacturers, and certain guarantee is provided for feed consumption by manufacturers with good after-sales service, which can be jointly carried out and promoted.
3. Feed price and packaging to see the choice of feed. In the fierce market competition, the cheaper materials are not necessarily of better quality. The ordinary and good feed packaging is relatively good, with clear printing characters, labels with certificates and numbers, and detailed factory date, consumption batch, and application explanation. There are clear contact number, manufacturer and service commitment on the package.
3、 At present, there are some misunderstandings in the use of premix in the market.
1、單一從豬糞的顏色，軟硬來判別飼料的“好壞”。豬糞顏色較深，不一定代表豬的消化良好，一種銅含量較高的飼料惹起的豬糞，顏色普通是較黑 的。飼料中 含有豐厚的保健藥物時，豬糞顏色有時會淺。豬的消化狀況，預混料以及其它飼料原料的品種及搭配等都會影響豬糞的顏色及軟硬。普通較正常糞便應是不干不稀， 不惡臭(但有時有氨氣息)，沒有異物。
1. Single from the color of pig manure, soft and hard to judge the feed "good or bad". The color of pig manure is darker, which does not necessarily mean that the pig has good digestion. Pig manure caused by a high copper content feed is usually darker. When the feed contains rich health care drugs, the color of pig manure sometimes will be light. The color and hardness of pig manure can be affected by the digestion of pig, the variety and collocation of premix and other feed materials. Common more normal feces should be not dry, not thin, no odor (but sometimes with ammonia breath), no foreign matter.
2. The "good or bad" of feed can be judged only from the appearance of pig fur.
3、呈現普通性疾病時，誤以為是由飼料惹起的。豬在飼養過程中由于環境、豬種、飼養狀況等不同要素會引發不同的疾病，很少會由飼料直接引疾病。 普通由飼料惹起的疾病及異常狀況有中毒、 食欲忽然改動等。發霉的飼料有時會惹起豬的腹瀉，飼料的改動有時會惹起其豬食欲的改動。
3. When presenting common diseases, they mistakenly thought it was caused by feed. In the process of raising pigs, due to different factors such as environment, pig species, feeding conditions, etc., different diseases will be caused by different feed. Common diseases and abnormal conditions caused by feed poisoning, sudden changes in appetite, etc. Moldy feed sometimes causes diarrhea in pigs, and changes in feed sometimes cause changes in pig appetite.
4. The quality of feed was judged by the flavor of feed. In order to increase the appetite of pigs, ordinary feed will participate in certain flavoring agents, but not necessarily very fragrant feed is what pigs like to eat. Pigs generally like milk flavor, fishy smell, strawberry flavor and so on. In order to arouse the attention of customers, some manufacturers participate in more flavoring agents, which only increase the invalid cost of feed.
5、混雜預混料所針對的豬生長階段以及在恣意參加別的飼料原料。例如用中豬預混料喂小豬，喂大豬。這樣的喂法不能發揮豬的較大生長潛能，還增加飼 料本錢。用4%預混料參加鹽、或骨粉等，看來似乎加了營養，但是過多參加食鹽可惹起蓄積輕度中毒。額外參加飼料原料反而降低養殖利潤，不過有時在正 確指引的狀況下參加適宜的其它物質是有效的補充。如調整性地參加藥物，碎青草等。
5. The hybrid premix is aimed at the growth stage of pigs and is free to participate in other feed ingredients. For example, pig premix is used to feed piglets and big pigs. This kind of feeding method can not give full play to the growth potential of pigs, but also increase the cost of feed. Adding 4% premix to salt or bone meal seems to have added nutrition, but too much salt can cause accumulation of mild poisoning. Additional feed ingredients can reduce the breeding profit, but sometimes it is an effective supplement to take part in other suitable substances under the correct guidance. Such as adjusting to participate in drugs, broken grass and so on.
6. The excessive pursuit of pig's body shape and price leads to the use of pig feed with stimulants or other additives, which has brought certain adverse effects to the society. In the state to stop the situation, it is an unreasonable behavior. Safe and environmental protection of high quality feed is the goal of breeding.
