When diets are used, each part of the feed required by the chicken is contained in a balanced and identical nutrient, otherwise it will cause malnutrition, deficiency or poisoning in the flocks, even if your diet formula is very scientific. The conditions are very good and still can't get satisfactory feeding results. Therefore, the feed must be stirred evenly to meet the nutritional needs of the chicken. There are two methods for mixing the food: mechanical mixing and manual mixing. If used properly, they can achieve satisfactory results.
Mechanical mixing: using a blender. Commonly used mixers are vertical and horizontal. Vertical mixers are suitable for mixing powdery feeds with a moisture content of less than 14%. Too much water content makes it difficult to mix evenly. This type of mixer requires little power, low price, and convenient maintenance, but it takes a long time to stir (usually 10-20 minutes per batch) and is suitable for professional chicken farmers and small chicken farms. Horizontal mixers can evenly mix feeds when adding viscous ingredients (such as oils and fats) to areas with relatively humid climates or feeds. The machine has strong stirring ability and short mixing time, each batch is 3 to 4 minutes, mainly used in some feed processing plants. No matter which type of agitator is used, in order to stir uniformly, the amount of charge should be appropriate. Too much or too little charge can not guarantee the uniformity, generally 60% to 80% of the capacity is appropriate. Mixing time is also an important factor related to the mixing quality. If the mixing time is too short, the quality will certainly not be guaranteed. However, it is not the longest the better. Stirring is too long, and the mixture is evenly mixed, resulting in delamination. phenomenon.
Hand-mixing: This method is the main means of feed mixing at home. When mixing, be careful and patience to prevent some trace ingredients from hitting heaps, agglomeration, mixing unevenly, and affecting feed effects.
Special attention should be paid to the hand-mixed ingredients that are small in the proportion of the diet but can seriously affect the feeding effect, such as salt and various additives. If the mix is ​​not uniform, the light will affect the feeding effect. In severe cases, it will cause diseases, poisoning, and even death of the chickens. For such trace ingredients, they must first be fully crushed when they are mixed, and there should be no agglomeration. The lumps cannot be mixed evenly, and poisoning may occur after being eaten by chickens. Second, due to the small amount of such ingredients, they cannot be directly added to bulk feeds for mixing, but should be premixed. The approach is: take 10% to 20% of the fine material (preferably a large proportion of energy feed, such as corn, wheat bran, etc.) as a carrier, and pile it up, and press the next batch of feed on the feed that was dropped in the previous one. That is, it is always put on the top of the feed, so that the feed flow around the center point into a conical shape, so that all kinds of feed can have a mixed opportunity. Repeatedly 3 to 4 times to achieve the purpose of mixing evenly, the premix is ​​made. Finally, this premix is ​​added to all the feeds, and the mixture is mixed 3 to 4 times in the same way.
When mixing by hand, only through such multi-level batching can ensure the quality of the diet. The method of turning or stirring the feed in place is not desirable.
