Application of hexadienoic acid in preparation of pig feed additive for improving pig quality

Abstract

The invention provides application of hexadienoic acid in preparation of pig feed additive and pig feed, which is novel important application of the hexadienoic acid, and can be applied to preparation of the pig feed additive or the pig feed. The pig feed added with the hexadienoic acid is a safe feed, and does not contain substances which are toxic or harmful to growth and health of pigs. Compared with conventional feed additives, the pig feed additive can effectively improve the pork quality while improving the secretion level of blood insulin-like growth factor-I (IGF-I) by the specificity of the pig feed additive and improving the growing performance of the pigs, so that the slaughtering speed can be increased, the grade of meat products can be improved, and the pork products have higher market values. In the application, additive amount of the hexadienoic acid is small, and can be directly added into premix, the adding process is convenient and rapid, and the preparation method is simple without special requirement for equipment, so the hexadienoic acid has quite wide popularization and application prospect.

Description

Technical field

[0001] The invention belongs to the technical field of feed additives, and specifically relates to the application of hexadienoic acid in the preparation of pig feed additives and pig feed containing hexadienoic acid. Background technique

[0002] Feed additives are substances with different purposes that are artificially added to various compound or mixed feeds for some special needs. Their function is to improve and strengthen the nutrition of the feed, promote the growth and development of pigs, prevent diseases, and improve the utilization rate of feed. And the quality of meat products. With the development of animal nutrition, physiology, feeding science, biochemistry, bioengineering, pharmacology, microbiology and other disciplines, the current feed additives have integrated various disciplines and technologies, and their functions, types and applications have been obtained. On the other hand, with the improvement of living standards, consumers have higher ...

Examples

Embodiment 1

[0034] (1) Weigh hexadienoic acid (this example uses C6 medium-chain conjugated hexadienoic acid, or other commercially available hexadienoic acid used to produce additives);

[0035] (2) According to the amount of 0.5-4kg hexadienoic acid / ton of feed, the hexadienoic acid is mixed with feed premixed materials to obtain a premix; or mixed with a carrier to make a premix; the hexadienoic acid can be mixed with the feed premixed raw materials. Conventional small-scale mixing equipment, the selection and dosage of the feed premixed raw materials and carriers refer to conventional ones, and vitamin or mineral premixes can be selected; the carrier is bran, corn flour or stone powder, etc.;

[0036] (3) Mixing the premix or premix obtained by mixing in step (2) with the full feed raw materials to prepare a full feed. The premix or the premix and the full-price feed materials can be mixed with conventional large-scale mixing and crushing equipment. The full-price feed materials refer to t...

[0038] Example 2 Effect of hexadienoic acid on growth performance of piglets

[0039] In order to study the effect of adiponic acid as a feed additive, two feeding trials were carried out in the pig farm of Guangzhou Lizhi Agricultural Co., Ltd. in 2006 and in the pig sound field of Hubei Topeke Breeding Co., Ltd. in 2008. The first experimental pig group was a three-element hybrid (Changda Du), with an average initial weight of 6.8 kg, and its feeding stage was defined as weaned piglets; the second experimental pig group was purebred approximately gram, and the initial average weight was 30 kg, the feeding stage is defined as the early fattening period.

[0040] During the pre-feeding period, the pig pens were adjusted, and they were randomly divided into 4 groups according to the weight close to each other and the ratio of half male to female, with 3 replicates in each group, with 20 pigs in each replicate. The control group was fed with a basal diet; the test group was fed with...

[0054] The test pig herd and the test method are the same as in Example 2.

[0055] In order to observe the effects of adiponic acid on the serum lipid metabolism, protein metabolism and hormone levels of pigs, after the first test, individual pigs with similar body weights were selected, and 2 pigs were selected for each repetition. Blood was drawn from the anterior vena cava and the serum was separated by centrifugation. The serum indexes were measured, including triglycerides, total cholesterol, total protein, urea nitrogen, IGF-I and cortisol. The results are shown in Table 3.
