Embodiment 1

[0031] A low-protein feed for broilers, comprising the following raw materials in parts by weight:

[0032]

[0033]

[0034] The present invention also includes conditioning and granulating devices, such as figure 1 As shown, the conditioning and granulating device includes a box body 1, and the middle part of the box body 1 is provided with a feed pipe 2, and the feed pipe 2 protrudes from the top of the box body 1. Preferably in this embodiment, the top of the box body 1 is also provided with a There is a cover body 11 threadedly connected with the feed pipe 2 . There is an arched tempering tank 3 inside the box body 1, the two sides of the conditioning tank 3 are symmetrical along the center line of the box body 1, and the two ends of the conditioning tank 3 are connected with the feed pipe 2; Two rotating shafts 31 inclined to the center line of the box body 1, one end of the rotating shaft 31 is connected with a motor 32; four conveying helical sections 33 are int...

Embodiment 2 and Embodiment 3

[0047] The difference between embodiment 2, embodiment 3 and embodiment 1 is that the input amount of raw materials is different, and the specific input amount is shown in table 1 below.

[0048] Table 1

[0049]

Embodiment 1 and comparative example 1

[0052] Example 1 used the feed prepared by this formula and preparation method to feed broiler chickens; Comparative Example 1 used conventional feed containing 20% ​​crude protein in the prior art to feed broiler chickens.

[0053] ①Ten 7-day-old Qingjiao hemp chickens were selected for each experiment. The test period was 1 week, and the last 3 days were the sample collection period. Feed intake and feces were collected, protein content was analyzed, and nitrogen balance was calculated.

[0054] ② 250 1-day-old Qingjiao hemp broilers were selected and randomly assigned to Example 1 and Comparative Example 1, with 5 replicates in each group and 50 chickens in each replicate. The test period was selected as 3 weeks, and the feed intake, initial weight and final weight were recorded, and the growth performance was calculated.

Abstract

The invention belongs to the technical field of livestock breeding and specifically discloses a low protein feed for chicken. The low protein feed contains the following raw materials in parts by weight: corn, swelling soya dreg, wheat, cottonseed meal, corn gluten meal, L-lysine, DL-methionine, L-threonine, L-tryptophan, monocalcium phosphate, calcium carbonate, table salt, glucose and energy utilization regulator. The invention also discloses a preparation method for the low protein feed for chicken. The preparation method specifically comprises the following steps: (1) mixing raw materials;(2) tempering and pelletizing; (3) drying and discharging. The low protein feed for chicken and the preparation method thereof have the advantage that the prepared feed is capable of effectively increasing the use ratio of protein of chicken and reducing the nitrogen discharge of chicken and has no influence on nitrogen deposition and growth performance of chicken.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding, and specifically discloses a low-protein feed for broilers and a preparation method thereof. Background technique [0002] In recent years, environmental pollution caused by nitrogen emissions has become increasingly serious with the continuous expansion of the scale and intensification of livestock and poultry farming. At present, the estimated value of global nitrogen emissions from livestock and poultry is as high as 89-164 million tons, of which the nitrogen emissions from monogastric animals (mainly pigs and chickens) account for about 60% of the total nitrogen emissions. At the same time, the shortage of protein resources is a common problem faced by the whole world. Therefore, how to improve protein utilization efficiency and reduce nitrogen emissions has become an urgent problem to be solved in my country's livestock and poultry breeding industry. In addition, cur...
