Low-protein low-calcium starter feed for goslings

Abstract

The invention discloses a low-protein low-calcium starter feed for goslings. The low-protein low-calcium starter feed is prepared from the following raw materials in parts by weight: 40-60 parts of corn, 10-20 parts of wheat middling, 10-15 parts of soybean meal, 5-10 parts of rapeseed meal, 5-10 parts of rice bran meal, 2-8 parts of rice polishing powder, 2-5 parts of a mixture of rice chaff and husk, 1-1.5 parts of stone powder, 1-2 parts of soybean oil, 0.2-1 part of calcium hydrophosphate and 1-2 parts of a core premix. Starting from the physiological digestion characteristics of the goslings, more proper raw materials (rice bran meal, rice bran and hull, rice polishing powder, rapeseed meal and the like) are selected, amino acid nutrition is designed by utilizing an ideal amino acid model, the content of crude protein and calcium in the starter feed for the goslings is reduced, reasonable cellulose nutrition is provided, the nutritional requirements of gosling growth can be met, and the physiological digestion characteristics of the goslings are met; and the gout of the goslings can be reduced, the survival rate of the goslings is increased, and feed cost is reduced by 15-20%.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed for goslings with low protein and calcium. Background technique [0002] my country is the country that raises the most geese in the world, and the goose industry is also an important part of animal husbandry. Although my country has a large amount of goose breeding, there are few studies on the nutritional requirements of meat goose feed, and no database information on the nutritional needs of geese has been established. , Most of them refer to the breeding standards of foreign geese. Due to the differences in species, it not only causes waste of feed resources, but also easily leads to the occurrence of nutritional diseases. The degree of specialization in meat goose feed in my country is not high. It is common to choose chicken feed and duck feed to raise geese, especially in the brooding stage of geese, which is basically fed with small chicken feed, without considering th...

[0002] my country is the country that raises the most geese in the world, and the goose industry is also an important part of animal husbandry. Although my country has a large amount of goose breeding, there are few studies on the nutritional requirements of meat goose feed, and no database information on the nutritional needs of geese has been established. , Most of them refer to the breeding standards of foreign geese. Due to the differences in species, it not only causes waste of feed resources, but also easily leads to the occurrence of nutritional diseases.

The degree of specialization in meat goose feed in my country is not high. It is common to choose chicken feed and duck feed to raise geese, especially in the brooding stage of geese, which is basically fed with small chicken feed, without considering the nutritional needs and needs of goslings. Balanced, the crude protein content of chick feed is 20-21%, the calcium content is 0.9-1%, and the crude fiber content is 2-3%. Inconsistent physiological and digestive characteristics often lead to waste of feed, unnecessary feed cost, and even the occurrence of nutritional and metabolic diseases
