Embodiment 1

[0014] Embodiment 1, the preparation technology of broiler chicken functional composite additive premix

[0015] The additive premix of the present invention is formulated from additives and carriers, and the content of three components is selected as any value in the following numerical ranges (such as Table 1): soybean isoflavones, glutamine, betaine, and tea polyphenols; The content of the additives is: soybean isoflavones 20-60 mg / kg, glutamine 300-500 mg / kg, betaine 800-1200 mg / kg, tea polyphenols 800-1200 mg / kg, and the balance is a carrier, the carrier is stone powder.

[0016] Table 1 Broiler functional compound additive premix

[0017]

[0018] The sensory requirements of the prepared additive premix are uniform color and luster, no moldy deterioration, agglomeration, peculiar smell and smell; Greater than 10%; the coefficient of variation (CV) of mixing uniformity is not greater than 5%.

Embodiment 2

[0019] Example 2, Application Effect Evaluation of Broiler Functional Precompound Additive Premix

[0020] A total of 1,800 1-day-old AA broiler chickens were selected and randomly divided into 6 treatments, each treatment had 6 replicates, and each replicate had 50 chickens. Divided into 1-3 weeks old, 4-6 weeks old two stages of feeding. The raw material composition and nutrient level of the basal diet are shown in Table 2. The control group is fed with the basal diet, and the test group uses the additive premix of the present invention and does not contain any additive in the premix, such as soybean isoflavones (S, 20~60mg / kg), glutamine (G , 300~800mg / kg), betaine (B, 500~1200mg / kg) or tea polyphenols (T, 400~1200mg / kg) to form a new additive premix to replace the carrier of the premix in the basic feed - zeolite Powder, namely: SGBT, SGB, SGT, SBT, GBT. The experimental animals were purchased from Huadu Commercial Broiler Hatchery. They were carried out according to th...

Embodiment 3

[0033] The mechanism of action of embodiment 3 broiler functional composite additive premix

[0034]The experimental design, feeding management and slaughtering methods are the same as in Example 2. Samples were taken from the same part of the right pectoral muscle for the determination of inosinate metabolizing enzyme activities, including ATP degrading enzymes, creatine kinase, adenylate dehydrogenase, alkaline phosphatase and 5' nucleotidase (see Table 5). ATP-degrading enzymes, creatine kinase, and adenylate dehydrogenase are key enzymes in the process of inosinate synthesis and metabolism, while alkaline phosphatase and 5' nucleotidase are key enzymes in the process of inosinate degradation. Take the left pectoral muscle for taste test, the test results are shown in figure 2 .

[0035] Result shows, add the ATP degrading enzyme, creatine kinase, adenylate dehydrogenase activity in broiler breast muscle of functional compound additive premix group of the present invent...

Abstract

The invention relates to the field of feeds, in particular relates to a chicken functional composite additive premix and application thereof. The chicken functional composite additive premix comprises 20 to 60mg / kg of soy isoflavone, 300 to 800mg / kg of glutamine, 500 to 1,200mg / kg of glycine betaine and 400 to 1,200mg / kg of tea polyphenol. The premix disclosed by the invention can greatly improve the deposition of inosinic acid in broiler chicken, and can effectively improve the freshness quality of the broiler chicken. The premix disclosed by the invention can reduce the content of the abdominal fat of the chicken, does not have adverse influence on the production performance and the carcass quality of the chicken, and is suitable for being applied to fast large chicken.

Description

technical field [0001] The invention relates to the field of feed, in particular to a functional composite additive premix for broilers and an application thereof. Background technique [0002] The food culture of the Chinese nation has always paid attention to the taste and taste. With the improvement of people's living standards, the demand for livestock products has shifted from the increase in quantity to the improvement in flavor quality. There are many evaluation indicators of meat flavor quality, mainly umami taste and aroma. For chicken, what consumers value more is its umami taste. It contributes the most to the umami taste of chicken. There are many determinants of umami taste, which can be summarized as amino acids and nucleotides. Among them, inosinic acid contributes the most to the umami taste of chicken, and has become an important indicator to measure the umami taste of meat. . The breed, gender, age and tissue of chickens have varying degrees of influenc...
