Problems solved by technology

At present, adding functional additives to pig feed has become the most common method for farmers to obtain pork with a high lean meat rate. However, food safety problems caused by feed additives are becoming increasingly serious. Antibiotics, heavy metals, and clenbuterol High residues such as corn have seriously endangered food safety; food safety, with the promotion of modern farming models, the demand for corn and other grains is increasing, and there are many safety problems in food production

Embodiment 1

[0021] 1. Make fermented mattress material

[0022] The types of raw materials used to make the fermented mattress material in this embodiment are shown in Table 1. According to the parts by weight listed in Table 1, various required raw materials were weighed in proportion. The total number of effective viable bacteria in the fermenting agent adopted in this embodiment ≥ 10 8 cfu / g, the effective live bacteria are composed of Bacillus subtilis, Bacillus licheniformis, Bacillus coagulans, Clostridium butyricum, yeast, lactic acid bacteria and coccus faecalis. : Bacillus coagulans: Clostridium butyricum: Saccharomyces: Lactic acid bacteria: Faecococcus = 1:1:1:1:2:2:1.

[0023] The raw material composition of the fermented bedding material of table 1 present embodiment

[0024]

[0025] Prepare fermented mattress material according to the following steps:

[0026] (1) adding the above-mentioned fermented bacterial agent to brown sugar water for activation and cultivation ...

Embodiment 2

[0056] This example was set up as a test example against Example 1, Comparative Examples 1-3.

[0057] 1. Pork quality inspection

[0058] At the end of the test period, the live weight of each pig was weighed when it was slaughtered, and 3 pigs were randomly selected for slaughtering experiments, and their meat yield and lean meat rate (the lean meat rate of the same part of each pig's lean meat content) were calculated. According to the regulations of NY-T 763-2004, 3 pork samples were randomly selected from each column to detect the sensory quality, fat and protein content and other indicators.

[0059] (1) live body weight: carry out the measurement of body weight when live pig is fasting;

[0060] (2) Meat yield (%) = [(live body weight - by-product amount - excrement and urine volume) / live body weight] × 100%;

[0061] (3) Lean meat rate (%) = (lean meat weight / carcass weight) × 100%;

[0062] (4) Protein content (g·hg -1 )

[0063] ={[(V 1 -V 2 )×C×0.014] / [m×(V ...

Abstract

The invention provides a breeding method of low-fat pigs. The breeding method comprises three aspects including production of fermentation bed padding, construction of a fermentation bed and feeding management of the pigs, wherein the fermentation bed padding is prepared from the following raw materials in parts by weight: 10 to 20 parts of sawdust, 10 to 20 parts of vinegar residue, 30 to 50 parts of coprinus comatus fungus chaff, 20 to 30 parts of cottonseed hull, 1 to 5 parts of microorganism inoculants, 0 to 10 parts of dicalcium phosphate and 3 to 5 parts of brown sugar; the living bacteria count in the microorganism inoculants is greater than or equal to 10<8> cfu / g, wherein an effective strain combination is composed of bacillus, saccharomycetes, lactic acid bacteria and enterococcus faecalis and meets the following effective living bacteria count ratio that the ratio of the bacillus to the saccharomycetes to the lactic acid bacteria to the enterococcus faecalis is (2 to 6) to (1 to 3) to (1 to 3) to (0.5 to 1.5). The decomposted fermentation bed padding and pig feed prepared by the invention meet a nutrient complementarity principle; the pigs are fed on the fermentation bedlaid by the fermentation bed padding and the fermentation bed can provide an enough turning-over and poking area for the pigs; the lean meat percentage and muscle protein content of the pigs are effectively improved, so that pork with better meat quality and mouthfeel is produced.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a method for raising low-fat pigs. Background technique [0002] With the improvement of living standards, people not only require rich nutrition, hygiene and safety to pork, but also require good local flavor. According to the survey, 83.7% of consumers admitted that they usually buy pork at home, 86.1% of them said they like fresh pork, and 40.3% like to eat lean meat. Compared with the previous survey conducted by the Academy of Agricultural Sciences, the consumption of ribs and lean meat The consumption of pork has greatly increased, and the proportion of consumption has accounted for 81.3% of pork consumption. With the improvement of income level and the enhancement of residents' nutrition knowledge and health awareness, the consumption demand for animal fat has decreased significantly, and the consumption of fat meat has only accounted for 81.3% of pork...
