Goose diet preparation technology

Geese feed on a day and night are called diets. The variety, quantity, and proportion of various nutrients in the diet can satisfy the needs of the organism called the full-price diet. According to the breeding standards, selecting different amounts of several kinds of feed to match each other so that it meets the needs of the nutritional needs of the goose is known as ration matching. The combination of diets is a very important technical link in the production of geese. Whether or not the rations are reasonable depends not only on the ability to achieve standardized breeding and the economic and rational use of various feed resources, but also on the health of geese, production performance and economy. The level of benefit. First, the basic principles of rations. The following principles should be taken into consideration when properly catering to rations: 1. Selection of reasonable feeding standards: All feeding standards have a certain degree of representation, but they have certain limitations, but are relatively reasonable standards. Therefore, in reference to the application of a certain standard, it is necessary to observe the actual feeding effect, according to the economic type, species, age, growth and development stage, weight, egg production rate and seasonal factors of the goose, and at the same time, the production of the goose family and the goose farm Specific conditions such as level and feeding experience are adjusted appropriately. 2. The use of feed should be economically reasonable: Under the premise of meeting the nutritional needs of the goose, feed costs should be reduced as much as possible. For this purpose, local feed resources should be fully utilized. The main raw materials for the diet must be abundant, and local advantages should be fully utilized. At the same time, we should consider the principle of economy and try our best to use nutritious and inexpensive feeds. 3, with the diet should consider the different types of goose's digestive physiology characteristics: goose than other poultry resistant to crude feed, diet can be properly selected some high fiber content of feed. 4, should pay attention to the palatability of feed: should try to use a good palatability of feed, for high nutritional value but bad palatability of feed, must limit their dosage, so that the entire diet has a good palatability, prohibit the use of Mildew feed etc. 5, the amount of dry matter should be appropriate: In addition to meeting the needs of various nutrients, diet should also pay attention to the amount of dry matter, that is, the diet should have a certain volume, should make the geese can eat, eat enough, It also meets nutritional needs. 6. Dietary requirements for diversification of feed: It is necessary to use as many feeds as possible in order to play a complementary role in the nutrient composition of various feeds in order to increase the nutritional value and utilization of the feed. Second, rations with methods. There are many methods for ration matching, such as the four-corner method, differential method, trial difference method, and computer calculation method. However, no matter which method is used, the more types of feed, the more nutrition index items will be, and the more complicated the calculation will be. 1, the four-corner method: the four-corner method, also known as the square method, diagonal line method. This method is intuitive and easy to understand, and it is suitable for use when there are few feed types and there are few requirements for nutrition indicators. 2, Poor Act: Poor Act, also known as simultaneous formula method. This method is to obtain the feed formulation ratio by solving linear simultaneous equations. 3, trial and error method: trial and difference method is the most commonly used method of diet matching in animal husbandry production. This method is based on feeding standards and feed supply conditions, the use of several kinds of feed, first preliminarily prescribed the amount of test mix, and then compare the nutrients contained in it with the feeding standards, the difference can be adjusted to meet the feeding standards . Application of trial and error method, after repeated adjustments and comparisons. The specific steps are as follows: (1) Find the feeding standard and list the nutritional requirements of the feeding target. (2) Check the nutritional value of feed and list the nutrient content of the feed used. (3) Initial allocation: According to the requirements of the feeding target and the proportion of various feeds during the diet, preliminary determine the amount of various feeds, and calculate the nutrient content, then add the nutrient content of various feeds, and Compare with feeding standard controls. (4) Adjustment: According to the degree of difference between the trial diets and the feeding standards, adjust the amount of some feeds, and then perform calculations and comparisons until they are in line with or close to the standards.
