Concentrated feed is a kind of semi-finished feed, which is scientifically and reasonably mixed with various protein raw materials (such as soybean meal, rapeseed meal, fish meal, etc.) and a certain proportion of minerals and additives according to the requirements of feeding standards. It is simple and convenient to use. When using, it is only necessary to flexibly master the self-produced corn flour and bran according to the reference formula on the label, but not directly Feeding. Pig OK small series found that some farmers, especially the scattered farmers in the selection of a lot of improper, in this targeted small retail Pig concentrate selection need to pay attention to several aspects, for your reference.
1. Distinguish type and stage, select material reasonably
The most prominent blind use of feed for small retail investors is to use concentrated fat pig mixed with corn flour instead of granular feed or concentrated feed of suckling pig. The result is just the opposite. There is no cost saving. On the contrary, it results in more lean suckling pigs, malnutrition and slow growth, which leads to the death of edema disease. Different kinds of livestock, different economic types and different growth stages of livestock and poultry have different requirements for various nutrients. According to their different nutritional requirements, there are many kinds of concentrates. Therefore, in order to achieve the best feeding effect, it is necessary to carefully understand the applicable object of the product and select the appropriate concentrated feed according to the number of livestock and poultry raised.
2. According to the reference proportion, reasonable ingredients
Concentrated feed is a kind of semi-finished feed, which should be made into full price feed according to different types and stages of livestock and poultry. However, at present, many farmers do not use the concentrated materials at one time, but scoop some concentrated materials with the lid of a kettle or a bowl according to imagination, and mix some corn flour and bran. It's just a short title at all. It's unscientific to make the concentrate according to the proportion. Therefore, in the preparation of full price material, the preparation should be carried out according to the reference proportion on the label, flexible application, and do not add too many other additives at will. For example, for lean meat pigs, we should select the concentrate suitable for lean meat pigs, and then according to the size of pigs and the reference formula on the label, we can prepare the compound feed suitable for lean meat pigs, and we will prepare the local Hybrid Pigs according to the needs of local pigs, so that the protein content can be appropriately lower, and we should consider making full use of our own agricultural and sideline products.
3. When using, the mixture should be even, and the nutrition balance of livestock and poultry should be achieved as far as possible
Concentrate feed and corn and other energy feed must be mixed evenly. For large-scale households, it is best to use material processing machine mixing, while for most of the scattered farmers, most of them are manual mixing. The method of manual mixing is: first, part of the energy feed is mixed with the concentrated material, fully stirred to achieve uniformity, and then a part of energy feed is added to fully mix and mix evenly. In this way, after many times of mixing and stirring, a uniform and uniform full price feed is prepared. If the mixture is not uniform, it can cause malnutrition of livestock and poultry and affect the feeding effect.
4. Avoid heating the batch
The full price material made of concentrated materials, mixed into hot cooked food, heated or fermented, will cause the loss of nutrients and seriously destroy the nutritional balance, especially the loss of vitamins, which directly affects the production performance of livestock and poultry. When feeding, raw materials should be fed dry or mixed wet.
5. Keep the feed properly and pay attention to the shelf life
The concentrated feed should not be stored for a long time. If it is stored too long, the potency of protein, vitamin, amino acid and other components in concentrated feed will gradually decrease, and even become moldy and caking. Therefore, we should pay attention to the production date and shelf life when purchasing concentrated feed. We should not buy too much at one time. It is better to use it for about half a month to a month. The prepared feed should be kept away from light, dry and ventilated, free from rat bites and insects, and free of peculiar smell, so as to avoid the damage of nutrients.
6. Do not change the material too often or when the material is not good
Some farmers do not have their own opinions. When they hear that the feed is good, they immediately change another kind of feed, or think that the first batch of new brand feed is good, they constantly change the feed and test it frequently; others think that the change of feed seriously affects the growth, and they know that the feed is not good, and they are not willing to change a good feed. The scientific way is to master the correct way to change the feed. When the feed is not very ideal, choose a good one and change it. The correct way to change feed is to gradually complete in 4-7 days, the original feed gradually reduced, the new feed gradually increased, mixed feeding, such a transition, can well reduce feed stress.
7. Do not feed pigs with the same standard feed regardless of size
Pigs with large difference in body weight should be kept in a pig house and fed with the same feed standard. The correct way is to raise pigs in groups according to their stages, which is conducive to the normal growth of pigs and does not waste feed.
