Problems solved by technology

[0003] Hexadienoic acid is a straight-chain fatty acid containing conjugated unsaturated bonds. It has a strong antibacterial effect and has no toxic or side effects on the body. It is widely used in the fields of food industry, health medicine, chemical industry, and feed industry, and is favored by countries all over the world. , is considered to be one of the safest additives, but the existing research results are to use hexadienoic acid as a preservative and acidifier in feed additives, such as "Adding α-amylase and hexadienoic acid to corn silage for meat calves Influence of Growth and Carcass Quality", Feed Wide Angle, 1991 (2): 27-31), reported the technical scheme of adding hexadienoic acid as a preservative to the corn silage feed of cattle, and did not find that hexadienoic acid has the effect of promoting cattle growth Effects on development and improvement of meat quality
At present, the relevant research on the effect of hexadienoic acid on the growth and development of pigs and the quality of meat is still blank, and there is no relevant technical report

Embodiment 1

[0034] (1) Weighing hexadienoic acid (the present embodiment adopts the hexadienoic acid of C6 mid-chain conjugate, also can adopt other commercially available hexadienoic acid for producing additive);

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

[0036] (3) Mixing the premix or premix obtained in the step (2) with the complete feed material to prepare the complete feed. Conventional large-scale mixing and crushing equipment can be used for premix or premix and complete feed raw materials. The complete feed raw materials refer to conventional ones,...

Embodiment 2

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

[0039] In order to study the effect of hexadienoic acid as a feed additive, two feeding experiments were carried out in the pig farm of Guangzhou Lizhi Agriculture Co., Ltd. in 2006 and in the pig farm of Hubei Topek Breeding Pig Co., Ltd. in 2008. The pigs in the first test were Sanyuan hybrid (Great Du), with an average initial body weight of 6.8 kg, and their feeding stage was defined as weaned piglets; the pigs in the second test were purebred large gram, with an average initial body weight of 30 kg, the feeding stage is defined as the pre-fattening stage.

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

Embodiment 3

[0053] Example 3 Effects of hexadienoic acid on blood biochemical indexes and hormone levels of piglets

[0054] Test pig group and test method are the same as embodiment 2.

[0055] In order to observe the effect of hexadienoic acid on the serum lipid metabolism, protein metabolism and hormone levels of pigs, after the first experiment, pigs with similar body weight 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 indicators were measured, including triglycerides, total cholesterol, total protein, blood urea nitrogen, IGF-I and cortisol. The results are shown in Table 3.

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 specificityof 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 in particular 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 uses that are artificially added to various compound or mixed feeds for some special needs. and the quality of meat products. With the development of animal nutrition, physiology, feeding, biochemistry, bioengineering, pharmacology, microbiology and other disciplines, the current feed additives have integrated various disciplines and various technologies, and their functions, types and applications have been obtained. On the other hand, with the improvement of living standards, consumers have higher requirements for pork quality. Through feed additives, the appearance, color and internal quality of livestock products can be improved, and the shelf life of livestock prod...
