Problems solved by technology

In the past few decades, feed antibiotics were mainly relied on to ensure animal health and promote growth. However, due to the many negative effects in the use of feed antibiotics, many countries and regions have gradually restricted or banned the use of feed antibiotics. Now we The country has also clearly banned the use of feed antibiotics
However, there are no related reports that rutin can promote the growth of poultry or improve the immunity of poultry, promote the development of immune organs of broiler chickens, and enhance the protective effect of broiler chickens on the intestinal barrier of poultry.

Embodiment 1

[0019] The effect of embodiment 1 different doses of rutin applied in broilers

[0020] In order to verify the growth-promoting effect of rutin on broiler chickens, 192 healthy newly hatched Avian broilers were randomly divided into 4 groups according to the principle of similar body weight, with 8 repetitions in each group and 6 chickens in each repetition. Feed the basic diet supplemented with 0, 250, 500 and 1000 mg / kg rutin feed, and raise them to 21 days old. During the feeding period, the feed intake and body weight were recorded, and the average daily gain, average daily feed intake, and feed-to-weight ratio were calculated. After the feeding experiment, one broiler chicken with close to the average body weight was selected for slaughter and sampling for each repetition, the blood hormone level was measured, the immune organ index was analyzed, and the blood immunity and intestinal barrier indicators were measured. The specific results are shown in Table 1 to Table 5. ...

Abstract

The invention discloses application of rutin as a growth promoting agent in poultry feed. It is found for the first time that when 200-1500 mg / kg of rutin is added into a feed for white feather broilers, the immunity of the broilers can be effectively enhanced, the intestinal barrier function is improved, ingestion of the broilers is promoted, and the daily gain and the feed utilization efficiency are improved. The rutin disclosed by the invention has the advantages of being green, environment-friendly, wide in source, low in cost and the like, and is a safe and efficient green feed growth promoting additive.

Description

technical field [0001] The invention relates to the field of livestock and poultry breeding, in particular to the application of rutin as a feed growth-promoting agent in poultry feed. Background technique [0002] In recent years, my country's aquaculture industry has developed rapidly, and the development of broiler aquaculture industry is particularly prominent, thereby providing humans with a large amount of animal protein products efficiently. Under the intensive breeding mode, broilers face various stresses during the actual breeding process, which seriously affects the intestinal function, reduces the immune function of the body, and then increases the probability of disease infection and inhibits growth. In the past few decades, feed antibiotics were mainly relied on to ensure animal health and promote growth. However, due to the many negative effects in the use of feed antibiotics, many countries and regions have gradually restricted or banned the use of feed antibi...
