How to control feed ingredients to ensure the quality and safety of raw milk?
(1) Requirements for feed making raw materials
It is prohibited to add drugs and other substances that are directly or potentially harmful to animals and humans in feed and drinking water; it is prohibited to add meat and bone meal, fish meal, bone glue and other animal-derived raw materials (milk and dairy products) to feed Except), and all kinds of feed processed with these raw materials; it is forbidden to add melamine, cyanuric acid and melamine-containing scraps in the feed.
(2) Feed hygiene requirements
The used concentrate supplements, concentrated feed, etc. must meet the feed hygiene standards; prevent the forage from being contaminated by the feces of farmed animals and wild animals to avoid causing diseases; do not feed moldy and deteriorating feeds to avoid yellowing in the fresh milk Residues of biological toxins such as aspergillus.
(3) Storage of feed
Prevent rain, moisture, fire, frost, mildew, rodents and insect pests; feed should be neatly stacked and clearly marked to facilitate first-in first-out; the feed storehouse should have a strict management system and accurate entry and exit , Materials and inventory records; storage and mixing of chemicals (such as pesticides, seed treatment drugs, etc.) should be kept away from forage and feed storage areas.
Types of animal feed raw materials
There are two standards for the classification of feed raw materials: IFN (International Feed Classification Method) and CFN (Chinese Feed Classification Method). Among them, IFN is an international standard, which divides feed raw materials into: roughage, green feed, and silage feed, energy feed, protein supplement, mineral feed, vitamin feed, and feed additives.
1. Rough fodder. Rough fodder refers to the feed that contains 18% or more crude fiber in the dry matter of the feed, and uses air-dried matter as the feeding form, such as hay and crop straw. The IFN format is 1—00—000.
2. Green feed. Green feed refers to green pastures, forage materials, leaves, non-starchy rhizomes, melons and fruits with a natural moisture content of more than 60%. The IFN format is 2—00—000.
3. Silage. Silage refers to feed made of natural fresh green plant feed as raw material, under anaerobic conditions, after fermentation with lactic acid bacteria as the main microorganisms, it has the characteristics of green and juicy. Such as corn silage. The IFN format is 3—00—000.
4. Energy feed. Feed that contains less than 18% crude fiber and less than 20% crude protein in dry matter is called energy feed, such as cereals, bran, starchy rhizomes, and fruits. The IFN format is 4—00—000.
5. Protein supplements. Feeds with crude fiber content of less than 18% and crude protein content of 20% or more in dry matter are called protein supplements, such as fish meal, soybean meal (meal), etc. The IFN format is 5—00—000.
6. Mineral feed. Mineral feed (minerals) refers to the chelates of natural minerals, chemically synthesized inorganic salts, organic ligands and metal ions for feeding. The IFN format is 6-00-000.
7. Vitamin feed. Single or compound vitamins synthesized or extracted by industry are called vitamin feeds, but do not include vitamin-rich natural green feeds. The IFN format is 7—00—000.
8. Feed additives. In order to facilitate the digestion and absorption of nutrients, improve feed quality, promote animal growth and reproduction, and protect animal health, small or trace substances incorporated into feed are called feed additives, but do not include mineral elements The IFN form of nutrient additives such as vitamins and amino acids is 8-00-000.
