Description
Technical field
The invention belongs to technical field of animal husbandry, and in particular, to a kind of cultural method of low fat pig.
Background technique
With the improvement of living standards, people pork is not required nothing more than it is full of nutrition, safe and healthy, but also require have it is good
Good flavor.According to investigation, 83.7% consumer recognizes that family generally buys pork, wherein 86.1% people indicates to like fresh
Pork, 40.3% people like eating inclined lean meat, and compared with the investigation done before Academy of Agricultural Sciences, the consumption figure of chop and lean meat is big
To increase, consumption specific gravity has accounted for pork consumption figure 81.3%, and with the raising of income level and resident's nutrient knowledge and is good for
The enhancing of Kang Yishi significantly reduces the consumption demand of animal fat, and fat meat consumption figure only accounts for the 3.9% of pork consumption figure.
High protein, low fat consumption concept gradually forming.The factor for influencing meat quality includes kind, age, gender, feed
How nutrition, feeding management etc. improve meat quality, become a hot spot of current Animal nutrition research.Currently, being raised in pig
Functional additive is added in material to be become raiser and obtains having the most common method of the pork of high lean meat percentage, still, feed
Food-safety problem brought by additive is also got worse, and the high residue of antibiotic, heavy metal, clenbuterol hydrochloride etc. is seriously endangered
Evil arrives the safety of food；Grain security, with the popularization of modernization aquaculture model, the demand to grains such as corns is more and more,
There is also more safety problems in grain-production.
Summary of the invention

2. testing result
Embodiment 1, comparative example 1, comparative example 2 and comparative example 3 for examination test pig deliver average work for sale
Weight is 272.31kg/, 241.78kg/, 268.44kg/, 253.79kg/ head respectively.Embodiment 1 and comparative example
1,2 butcher that the pork of experiment examination pig only is glossy, and red uniformly fat is creamy white, fleshy fiber is clear, flexible.
And butchering in the pork of experiment examination pig only for comparative test 1 has thicker milky fat deposit, the reflecting feel and toughness of muscle
It is poor.As shown in Figure 1, all dressing percentage differences for trying test pig are unobvious；As shown in Fig. 2, each group is for the thin of examination test pig
Meat rate size relation are as follows: 1 > comparative example of embodiment, 2 > comparative example, 3 > comparative example 1.Each group is for trying test pig
Muscle protein content and muscle fat content distinguish as shown in Figure 3 and Figure 4, the confession of corresponding embodiment 1 and comparative example 2
It has a try and tests the muscle protein content that pig muscle protein content is significantly higher than corresponding comparative example 1, and correspond to comparison and implement
The muscle fat content of example 1 then reaches the maximum value in the test group of all participation the present embodiment tests.According to the present embodiment
Test result it is found that embodiment 1 construct fermentation bed on raise pig, can significantly improve pig lean meat percentage, reduce pig
Muscle fat content only, and the pannage for utilizing embodiment 1 to prepare feeds pig, can also send out the raising of pig lean meat percentage
Wave certain facilitation.
