Embodiment 1

[0012] Proportion (weight ratio): X (betaine and choline chloride 3:1) 11%, Y (lipase and bile acid 1:1) 2.0%, Z (Bacillus subtilis) 10.0%, bran 77.0% .

[0013] Preparation method: After mixing X, Y, Z with bran, add VE and spray oil. According to production needs, produce 100kg X, Y, the mixture of Z and bran, then add VE 2kg, spray grease 2.5kg in this batch mixture.

[0014] Select 40 Dudachang three-way hybrid pigs weighing 60±0.5kg, and randomly divide them into control group and test group, with 4 replicates in each group and 5 pigs in each replicate. The control group was fed with a corn-soybean meal-based ration; the experimental ration of the test group was the additive of the present invention added to the basal ration, and the additive amount was 1.0%. The basal ration was formulated according to the national pig nutrition standard in 2004, and its specific indicators were 13.0MJ / kg of digestible energy, 15% of crude protein, and 0.8% of lysine. The pre-feeding ...

Embodiment 2

[0023] Proportion (weight ratio): X (betaine and choline chloride 2:1) 12%, Y (lipase and bile acid 2:1) 3.0%, Z (Bacillus licheniformis) 8.0%, corn flour 77.0% .

[0024] Preparation method: After mixing X, Y, Z with bran, add VE and spray oil. According to production needs, produce 100kg X, Y, the mixture of Z and bran, then add VE 2kg, spray grease 2.5kg in this batch mixture.

[0025] Test method: Select 40 Dudachang three-way hybrid pigs with a body weight of 60±0.5kg, and randomly divide them into a control group and an experimental group, with 4 repetitions in each group and 5 pigs in each repetition. The additive is mixed evenly in the pig compound ration (prepared basal ration according to the national pig nutrition standard in 2004) in the proportion of 1.2% by weight, and is raised on the fermented mattress material. The pre-feeding period is 7 days, and after 52 days of the formal period , each group randomly selected 10 heads for slaughter.

[0028] Proportion (weight ratio): X (betaine and choline chloride 4:1) 14%, Y (lipase and bile acid 1:2) 2.5%, Z (Bacillus cereus) 8.0%, rice bran 75.5% .

[0029] Preparation method: After mixing X, Y, Z with bran, add VE and spray oil. According to production needs, produce 100kg X, Y, the mixture of Z and bran, then add VE 2kg, spray grease 2.5kg in this batch mixture.

[0030] Test method: Select 40 Dudachang three-way hybrid pigs with a body weight of 60±0.5kg, and randomly divide them into a control group and an experimental group, with 4 repetitions in each group and 5 pigs in each repetition. The basal diet was formulated according to the 2004 National Pig Nutrition Standard. The additive is mixed evenly in the pig formula ration at a ratio of 1.1% by weight as the test ration. The two groups of pigs were reared on the concrete floor, the manure was dried and cleaned manually, and the pigs ate freely. The pre-feeding period was 7 days, and after the formal period w...

Abstract

The invention discloses a feed additive for increasing the content of intramuscular fat of external ternary pigs and a using method for the feed additive, and belongs to the technical field of feeds. The feed additive comprises the following components: betaine, choline chloride, lipase, bile acid, bacillus, a carrier, vitamin E (VE) and grease. The using method comprises the following steps of: when the body weight of external ternary hybrid pigs is 60+ / -1kg, uniformly mixing 1.0 to 1.5 weight percent of additive and compound daily ration of the pigs, raising on the cement ground or on fermentation bed padding, feeding for 40 to 60 days, taking out and slaughtering. According to the metabolic rule of fat in human bodies, the comprehensive regulation and control in multiple links of digestion, absorption, synthesis and decomposition of the fat are performed to improve the deposition effect of the intramuscular fat, and the content of the intramuscular fat is increased on the premise of not increasing the thickness of backfat and not prolonging the feeding period, so that the content of the intramuscular fat of longissimus dorsi of the external ternary hybrid pigs is improved by over 40 percent, the meat quality is improved, and the odor of hog houses is remarkably reduced.

Description

technical field [0001] The invention relates to a feed additive for increasing the intramuscular fat content of exoternary pigs and a use method thereof, belonging to the technical field of feed. Background technique [0002] In order to meet people's needs for protein, my country has introduced a large number of purebred lean-meat pigs from abroad, such as Duroc, Yorkshire, Landrace, etc. Three kinds of pig hybrids), three-way hybrid pigs grow fast, have high lean meat yields, but have low intramuscular fat content and poor pork taste. The external three-way hybrid pigs are generally released for slaughter within 5 to 6 months, with a weight of about 100kg when released, and the fat content in the muscle is generally lower than 2%. There are many local pigs in our country, including Laiwu pigs and Jinhua pigs. Local pigs in my country have high intramuscular fat content and good pork taste, but they grow slowly and take 8 to 10 months to slaughter, and have thick backfat a...
