Problems solved by technology

[0002] The high-intensity selection of pig growth rate, feed remuneration and carcass lean meat index in modern breeding, as well as the continuous improvement of nutritional formula in order to give full play to the genetic potential of meat pigs, have maximized the growth performance of meat pigs, but However, due to ignoring the selection of quality and performance, the meat pigs of modern bred breeds have weak disease resistance, are prone to stress, and cause internal balance disorders in the body, resulting in a decline in muscle quality and poor quality meat.

Embodiment 1

[0029] In the experiment, 128 piglets of about 20 kg in good growth, healthy and disease-free, with basically the same weight after weaning, were selected as three-way hybrid piglets. They were randomly divided into 4 groups, with 8 replicates (pens) in each group, 4 piglets in each replicate (pen), half male and half female, and the feeding period was about 3 months.

[0030] The composition of the feed is as follows: the basic feed is prepared according to the feeding standards of pigs in different feeding periods. The first group (group A, being the control group) was fed with basal feed; the second group (group B) was fed with basal feed+100mg / kg curcumin; the third group (group C) was fed with basal feed+150mg / kg turmeric The fourth group (group D) was fed basal feed+250mg / kg curcumin. The formula is shown in Table 1.

Embodiment 2

[0037] Select 64 weaned three-way hybrid piglets with about 20kg in good growth, healthy and disease-free, and basically the same body weight, and randomly divide them into 2 groups, with 8 replicates (columns) in each group, 4 piglets in each replicate (column), male and female Half and half.

[0038] Feed composition is the same as before. That is, the first group was fed with basal feed (being the control group); the second group was fed with basal feed+150mg / kg curcumin.

[0039] The results are shown in Table 3, and Table 3 shows that curcumin can improve average daily gain and reduce feed-to-weight ratio. More importantly, curcumin had an effect on pig carcass traits and pork quality, including offal (see Table 4). As shown in Table 4, curcumin had no effect on the pH value of the carcass 1 h after slaughter, but significantly reduced the pH value of the carcass after cooling for 24 h; curcumin affected fat metabolism, and may affect the deposition of subcutaneous fat,...

Embodiment 3

[0045] Select 64 weaned three-way hybrid piglets with about 20kg in good growth, healthy and disease-free, and basically the same body weight, and randomly divide them into 2 groups, with 8 replicates (columns) in each group, 4 piglets in each replicate (column), male and female Half and half.

[0046] Table 5 Effect of Curcumin on Serum Immunoglobulin and Physiological and Biochemical Indexes

[0047]

[0048] As can be seen from Table 5, adding curcumin in the pig feed can significantly improve the concentration of immunoglobulin IgG in the serum, from 361.51mg / dL of the control group to 404.20mg / dL of the test group, although the concentration of IgM in the serum of the test group is 99.07mg / dL was higher than 90.47mg / dL in the control group. The results of this assay indicated an elevated immunoglobulin concentration, but within the normal physiological range, rather than an inflammatory response. In addition, curcumin can significantly reduce blood sugar and serum ch...

Abstract

The invention relates to an animal feed and a production method thereof. The animal feed is composed of basic feed for pigs and curcumin or curcuma residues. In the animal feed, the additional amount of curcumin is 5-1000 mg per kg of basic feed for pigs, or the additional amount of curcumin is 5-300 g per kg of basic feed for pigs. The production method comprises the following steps: pulverizing curcumin or curcuma residues and basic feed for pigs respectively, mixing 1000,000 weight parts of basic feed for pigs with 5-1000 weight parts of curcumin and stirring thoroughly, or mixing 1000 weight parts of basic feed for pigs with 5-300 weight parts of curcumin and stirring thoroughly.

Description

technical field [0001] The invention relates to an animal feed and a preparation method thereof, and more particularly relates to an animal feed which can promote the growth of pigs, improve the comprehensive quality of pork, and enhance the immunity of pigs and a preparation method thereof. Background technique [0002] The high-intensity selection of pig growth rate, feed remuneration and carcass lean meat index in modern breeding, as well as the continuous improvement of nutritional formula in order to give full play to the genetic potential of meat pigs, have maximized the growth performance of meat pigs, but However, because of ignoring the selection of quality and performance, the modern breeds of pigs have weak disease resistance, are prone to stress, and cause internal balance disorders in the body, resulting in a decline in muscle quality and low-quality meat. The most typical poor quality pork is PSE (pale, soft, moist) meat, followed by DHD (dark, firm, dry) meat....
