Compound premix for Nongda No. 3 grain-saving small laying hens in brooding period

Abstract

The invention discloses a compound premix for Nongda No. 3 grain-saving small laying hens in the brooding period. The compound premix comprises the following components in parts by mass: 27 to 33 DL-methionine, 18 to 22 lysine sulphate, 5.5 to 6.55 choline chloride, 1.125 to 1.245 aureomycin, 2.6 to 3.3 phytase, 0.4 to 0.6 antioxidant, 370 to 450 rock flour, 80 to 90 common salt, 230 to 270 calcium hydrophosphate, 221.5 to 77.7 medical stone, 25 compound trace elements for Nongda No.3 grain-saving small laying hen chicklings and 7 multivitamin for Nongda No.3 grain-saving small laying hen chicklings. The premix is specially developed according to physiological characteristics and nutritional needs of the Nongda No. 3 grain-saving small laying hens, has strong pointedness, well meets the nutritional needs of the Nongda No. 3 grain-saving small laying hen chicklings, and has the advantages of obvious feeding effect, high survival rate of the chicklings, high rate of compliance of weightand good uniformity. The invention has great economic value to cultivation of the Nongda No. 3 grain-saving small laying hens in the laying period.

Description

technical field [0001] The invention relates to a composite premix for Nongda No. 3 grain-saving small-sized laying hens during the brooding period. Background technique [0002] Agricultural University No. 3 grain-saving small laying hens are Chinese's own laying hens bred by Academician Wu Changxin, Professor Yang Ning, and Professor Ning Zhonghua. Due to the advantages of Nongda No. 3 grain-saving small laying hens with small size, less material consumption, and good egg quality, farmers of Nongda No. 3 dwarf laying hens have achieved higher benefits than breeding ordinary commercial laying hens. [0003] Compared with ordinary laying hens, Nongda No. 3 grain-saving small laying hens have the following characteristics: (1) Small size and less floor space; Nongda No. 3 grain-saving small laying hens weigh 1.60kg, which is 25% lighter than ordinary laying hens Its natural body height is about 10 cm shorter than that of ordinary laying hens; (2) it consumes less material an...

AI Technical Summary

Problems solved by technology

However, the physiological metabolism and nutritional requirements of Nongda No. 3 dwarf laying hens are different from those of ordinary commercial laying hens, so the requirements for various nutrients such as feed protein, amino acids, vitamins, and trace elements are different from those of ordinary commercial laying hens. It is difficult to reach the standard body weight when the chick premix is ​​fed to Nongda No. 3 grain-saving small layer chicks, and the uniformity and survival rate are low, which affects the production potential of the laying period
