The principle of dietary preparation of unreasonable meat geese

In recent years, the goose market is optimistic, breeding benefits are high, but when feeding geese, some farmers are very casual,"what to feed what", resulting in poor benefits. The following principles should be followed in preparing meat goose diet:

1. Complete: goose diet nutrition must be comprehensive to meet the needs of growth and development of meat geese of all ages. Under normal circumstances, the protein content of goslings before 4 weeks of age should reach 20%; the protein content of geese after 4 weeks of age should be 18%. The ration of calcium and phosphorus was reasonable, the ration of calcium and phosphorus was 2∶1, calcium content was 1% and phosphorus content was 0.45% for goslings and 3∶1, calcium content was 2% and phosphorus content was 0.7% for geese. The salt content in diet should be controlled properly, 0.3%~ 0.44% for goslings and 0.4%~0.5% for geese. During the growing period before 10 weeks of age, the metabolic energy per kilogram of feed was 11.3 MJ; during the fattening period after 10 weeks of age, the energy increased and the protein decreased, the metabolic energy per kilogram of feed was 11.7 MJ, and the protein decreased to 12%.

2. Targeting: When preparing meat goose diet, we should make full use of local feed and minimize outsourcing. In this way, under the premise of ensuring nutrition, we can minimize breeding costs and obtain maximum benefits. If there is grazing condition, grazing is the main way and supplementary feeding is the auxiliary way in the goose section. At this time, the feed energy should be increased to 0.84 MJ/kg, the protein content should be reduced to 1%~2%, and the salt content should reach 0.5%. During feather growth period, the demand of meat geese for sulfur-containing amino acids increased, so the use of sulfur-containing amino acid additives such as methionine, cystine and cysteine could be increased, or feather meal could be added by 3%~5% in feed. Different breeds of meat geese have different requirements for nutrition. The characteristics of meat goose breeds should be fully considered in preparing diets.

3. Rationality: The feeding and digestion characteristics of geese should be fully considered when preparing goose diet. In meat goose feed, protein feed generally accounts for 40%~60%, bran accounts for 15%~20%, cake accounts for 10%~15%, animal feed accounts for 3%~5%, mineral feed accounts for 2%~3%. Leguminous hay powder is rich in protein, and proper increase can reduce protein feed consumption and feed cost, and the dosage can reach 15%~30%. Feather meal, blood meal and other feeds, although the protein content is high, but the meat goose digestibility is low, the addition amount should be below 5%. Goose is herbivorous waterfowl. If there is no grazing condition, proper amount of high-quality grass should be planted. After cutting, it should be added to the diet of meat goose. 3%~5% hay powder can also be added to the feed. Meat geese are easy to be picky eaters. If conditions permit, the powder can be processed into granules, which can prevent waste caused by picky eaters, facilitate feeding and intake, and reduce feed pollution in meat geese.

4. Stability: Goose diet should be adjusted continuously with the growth of age, but the adjustment of feed formula should have a transition period of 1 week. In a certain growth period, the stability of diet formula should be maintained to prevent frequent or sudden changes in diet from causing stress. The composition of daily ration should also have certain stability. Whether corn, sorghum or wheat or rice should be selected for energy feed; whether cottonseed cake, rapeseed cake or bean cake or peanut cake should be selected for protein feed; whether fish meal, silkworm chrysalis powder or blood meal or meat and bone meal should be selected for animal feed. All of them should be considered comprehensively. They should be flexibly controlled according to the characteristics of local production and meat goose varieties. Once determined, they should not be changed easily. Goose muscle stomach and cecum are very developed, big goose can digest 40%~50% crude fiber in feed, young goose fiber content should account for 5%~7%, maintain the stability of crude fiber in feed, not only meet the physiological needs of meat goose, but also reduce feed cost.

5. Safety: The raw materials selected for preparing meat goose diet should be reliable, free of moth, mildew, pesticide pollution, and other toxic and harmful substances. Meat goose can eat a variety of green feed, but the use of attention to hygiene, green feed to wash, aquatic feed to dry to half, can not be fed casually. If you need to feed gravel, choose river sand from pollution-free river sections, wash it with clean water, dry it, and feed it separately in containers. The dosage should be appropriate each time to prevent pollution caused by too long a time. Farmers storage conditions are limited, summer and autumn each time can only be prepared for 3 to 5 days of use of the diet, a preparation of too much easily moldy deterioration. When feeding wet mix, mix accurately according to the feed intake of meat geese, and do not have overnight leftovers. Do not feed grass slurry overnight to prevent nitrite poisoning. Green feed containing more oxalic acid, such as spinach, sweet cabbage leaves, etc., should not be overfed gosling to prevent rickets.

6. Palatability: When preparing meat goose diet, the raw materials selected should have good palatability. Raw materials with hard shell or seed coat, such as rice, wheat, corn, etc., are best crushed and processed, and then mixed with other raw materials. Cereal raw materials should not be ground too finely, as too fine may affect intake and palatability. Bean curd residue contains anti-trypsin, which must be heated and cooked before use. In addition, the water content is large, so it is best to mix it into the diet after drying. In order to facilitate meat goose intake, green feed, rhizomes and juicy feed should be chopped and fed, and vegetables with more crude fiber should be cut as fine as possible.
