Embodiment 1
[0040] 1. A low-cost broiler feed formulation
[0041] The crude protein in the feed formula was reduced by 2 percentage points compared with the feeding standard, and 0.3% compound supplement was added at the same time. Composite additives (w / w) quinoline quinone disodium 0.6, β-alanine 100, glycine 880, rice husk powder 19.4.
[0042] 2. How to use compound additives
[0043] Firstly, the basic substances in the feed including corn, soybean meal, etc. are crushed and mixed according to the proportion of the feed formula, and then added in an amount of 0.3% and then fully mixed.
[0044] After the broiler feed is prepared, store it in a cool and ventilated place at room temperature.
Embodiment 2
[0046] A trial of a low-cost broiler feed that increases daily gain, increases breast muscle production, and reduces nitrogen emissions.
Embodiment 3
[0049] 1 Experimental design and diet formulation
[0050] Select 216 Ross-308 broiler male chicks with an average body weight of 42±0.5g at 1 day of age, divide them into 2 treatments, each treatment has 9 replicates, and each replicate has 12 chickens, and the normal control group is fed with conventional corn-soybean meal basis In the diet, the low-cost group reduced the amount of soybean meal and oil, increased the amount of corn, and the crude protein was about 1.5-2 percentage points lower than that of the control group, and added 2kg of compound additives per ton of feed. The feed is stored in a cool and ventilated place at room temperature.
[0051] An example of the test formula (per ton) is as follows:
[0052] (1) Feed in the early stage of the experiment (0-3 weeks):
[0053] 1) Control group: corn 582kg, soybean meal 348.8kg, vegetable oil 25.4kg, calcium hydrogen phosphate 22.7kg, stone powder 8.2kg, salt 1.4kg, methionine 3.1kg, lysine hydrochloride 3.4kg, pre...

Abstract
The invention relates to a formula for reducing feed cost of chicken and an application thereof. According to the formula, the protein content of the feed is 1.5-2% lower than that of feeding standard, and meanwhile, 0.2%-0.3% of compound additive containing the main components of pyrroloquinoline quinone, beta-alanine, glycine, and the like is added. The cost of the feed according to the invention is accordingly reduced by 80-100 Yuan / ton. The feed formula provided by the invention can be used for reducing the feed cost of chicken, promoting the growth of the broiler chicken individuals, increasing the feed efficiency, increasing the brisket yield, improving carcass quality, obviously reducing nitrogen emission and reducing environmental pollution caused by the chicken feeding. Thus, thefeed formula has excellent application prospect in the aspects of reducing the chicken feed cost, reducing nitrogen emission and improving chicken carcass quality and has obvious economic benefit.
Description
technical field [0001] The invention relates to a formula for reducing the feed cost of broilers and an application thereof, belonging to the technical field of feed. Background technique [0002] my country's feed resources, especially protein resources, are seriously lacking, and a large amount of soybeans and fish meal need to be imported from abroad every year. In 2016, my country imported 83.91 million tons of soybeans and 1.037 million tons of fishmeal. Protein feed generally accounts for 20% to 40% of the diet, accounting for more than 1 / 3 of the diet cost. Therefore, a lot of work has been carried out on the rational use of protein resources and the improvement of crude protein utilization. According to the requirements of ideal protein, through the deployment of feed materials and the supplement of crystalline amino acids, low-protein diets with balanced amino acids can be prepared, so as to alleviate the pressure of lack of feed materials and reduce feeding costs...
