Embodiment 1

[0022] 1. Experimental animals

[0023] Select 1296 1-day-old broiler chickens, randomly divide them into 4 treatments according to male and female and body weight, each treatment has 12 replicates, each replicates 27 chickens, each replicate is divided into 3 cages and 3 layers of rearing, each cage bottom The area is 0.54 m 2 , high-density feeding, the test period is 42 days, feeding in two stages.

[0024] 2. Diets and experimental design

[0025] Before the start of the experiment, collect the feed raw materials used, analyze their conventional nutrient content, and make the feed formula based on the actual test results. The content of other nutrients in each raw material refers to "China Feed Composition and Nutritional Value Table 2017", and the nutritional requirements refer to NRC (1994) Breeding Standards for Broilers. The control group was fed with basal rations; the test group was fed with 25g / t 5-ALA in the basal ration; the test group 2 was fed with 150g / t fee...

Embodiment 3

[0064] 1. Experimental design

[0065] In the experiment, 1380 healthy Korean quails aged 36 weeks were randomly divided into 4 groups with 6 replicates (cages) in each group. The feeding amount of each repetition (cage) quail in the test group is 60 / cage, and the feeding amount of the test group 2, test group 3, test group 4, test group 5, test group 6, and test group 7 is 65 / cage. cages, the first and second groups were fed with basal rations, the third group was fed with 25g / t 5-ALA in the basal rations, the fourth group was fed with 35g / t 5-ALA in the basal rations, and the fifth group was fed with In order to add 150g / t feed enzyme preparation + 150g / t Enterococcus faecalis to the basal diet, the six experimental groups added 25g / t 5-ALA+150g / t feed enzyme preparation+150g / t to the basal diet Enterococcus faecalis; the test quails were raised in stacked cages, and the area of ​​the quail cages was 0.7345㎡ 2 . The pre-test period is 3 days, and the main test period is 2...

Abstract

The invention discloses a feed additive for improving the oxygen obtaining ability of poultry. The feed additive comprises an active ingredient 5-aminolevulinic acid. The feed additive can also be anadditive which is compounded and added according to the mass fraction: 2-10%wt of 5-aminolevulinic acid, 10-45%wt of feed compound enzyme, 10-45%wt of enterococcus faecalis and 0-75%wt of carrier. Theinvention also discloses application of the feed additive in poultry breeding. The feed additive provided by the invention is applied to poultry breeding, especially high-density poultry breeding andpoultry breeding in high altitude areas, can obviously reduce the death and culling rate of poultry, and can improve the production performance of poultry. The product provided by the invention has relatively strong economic application benefits and market promotion values.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive added in poultry breeding, which can effectively improve the oxygen supply capacity and improve the survival rate and production performance of poultry and its application. Background technique [0002] In modern poultry farming, in order to pursue higher economic benefits, high-density farming is a common phenomenon, and stocking density is an important factor affecting poultry production performance. In the case of insufficient oxygen in high-density or high-altitude areas, the production performance of poultry will decline. Especially in the winter breeding process, the ventilation in the shed is not smooth, which can easily cause problems such as insufficient oxygen supply and increased death rate of poultry. Studies have found that 5-aminolevulinic acid can improve the body's hematopoietic function and oxygen transport efficiency, thereby improving the...
