Fattening pannage feed intake is counted, daily ingestion amount, feedstuff-meat ratio are calculated；Count feeding time.
3, meat
Meat quality determination is carried out after butchering to test pig, measuring method is referring to the matter performance measurement of NY/T 821-2004 pig muscle
Technical specification.On-site measurement is carried out to indexs such as yellowish pink, marble grain, pH, drip loss, percentage of water loss, cooked meat percentages；Intramuscular fat
Content, muscle fatty acid composition, the sampling of diameter of muscle fiber sign spot, take back experimental determination.
Specific assay method is as follows：
(1) yellowish pink measurement
1. sampling sites：Longissimus dorsi muscle at last thoracic vertebrae.
2. assessing terms：With the fresh meat sample butchered in rear 1~2h, range estimation and the mark that scores are carried out under normal illumination indoors
Quasi- figure comparison evaluation.
3. evaluation criteria：By Color Score standard drawing, sample is evaluated using 5 points of systems yellowish pink：1 point-canescence；2 points-
Blush；3 points-cerise；4 points-peony；5 points-kermesinus.If occur between two grades when scoring,
It can be chosen as 0.5 point.Normal yellowish pink generally 3~4 points, then there are the suspicion of white muscles (PSE meat), 5 points or so of sample less than 2 points
Then there is the possibility of black biltong (DFD meat).
(2) muscle marble grain
Evaluate the index of fat content and distribution situation in muscle.
1. sampling point：Thoracolumbar disk junction longissimus dorsi muscle.
2. assessing terms：Test pig is butchered in 1~2h, and 0~4 DEG C of refrigerator cold-storage carries out mesh for 24 hours, with NPPC color board made in U.S.A
Assessment point.
3. standards of grading：Scoring is made using 5 points, allows to comment 0.5 point between two-stage.1 point (fatty trace)；2 points (fat is micro-
Amount)；3 points (being measured in fat)；4 points (fatty volume)；5 points (fat is excessive).3~4 points of marble grain represent it is with good meat quality.
(3) muscle pH
Body development in pig postmortem muscle generates lactic acid by the glycolysis of anaerobic metabolism approach, with the accumulation flesh of lactic acid in muscle
The pH of meat declines, the degree of pH decline to it is yellowish pink, be that waterpower, soluble protein concentration, shelf life length all have a significant effect, because
But evaluate an important indicator of meat.
1. sampling point：Longissimus dorsi muscle at last thoracic vertebrae.
2. instrument：It is accurate to 0.01 PHS-25 type digital display acidometer (German R.Matthaus company PH-STAR), is measured
Preceding pH meter must be corrected with pH4 and pH7 titer.
3. operating：45~60min measures chest waist junction longissimus dorsi muscle pH after bloodletting, as pH45.It is taken out for 24 hours after government official
0~4 DEG C of cooling eye muscle middle section is cut, and pH meter electrode insertion joint-cutting is measured pH24 (PHU).
(4) percentage of water loss measures
Longissimus dorsi muscle is taken at third and fourth thoracic vertebrae, is taken with sampler after test pig is killed in 1~2h using weight pressurization
Radius and thickness are the small circle sheet of 1cm.Between meat sample is placed in two layers of gauze after weighing (W1, g), 18 layers are respectively padded above and below
Filter paper is placed on the pressure device that induction amount is 0.019, pressure 35kg together together with filter paper, is taken out meat sample after the 5min that pressurizes and is claimed
Weight (W2, g).Percentage of water loss is smaller, is that waterpower is higher.
Percentage of water loss W=[(W1-W2)/W1] × 100%.
(5) shearing force measures
Longissimus dorsi muscle waist paragraph header side sample is taken, is fitted into polybag, after 4 DEG C of refrigerators cure 48h, is stood at room temperature
1h.75~80 DEG C of water-baths are immersed, reaches 70 DEG C to meat sample central temperature and takes out meat sample, be cooled to 20 DEG C, by meat sample core
Divide and accomplishes 1 × 1 × 2.5cm3Cutlet (it is consistent with longitudinal direction that muscle fibre moves towards direction), with C-LM type Meat Tenderness instrument survey cut
Shear force.
(6) cooked meat percentage measures
After test pig is killed in 1~2h, greater psoas muscle middle section about 100g meat sample is taken, is weighed (W1, g), is placed on pot drawer and steams 30min
After hang on shady place 15min, weigh (W2, g).Cooked meat percentage (%) ﹦ (W2/W1) × 100%.
(7) intramuscular fat content measurement (soxhlet extraction)
1. sampling point：After butchering, it is sent to laboratory as early as possible, takes longissimus dorsi muscle at the 6th~7 rib cage or the 11st~12 rib cage
Marble grain scoring is carried out, intramuscular fat content measurement is then carried out.
2. pre-treatment：Air-drying sample is made for measuring meat sample over dry moisture content, 65 DEG C of a part in chopping, a part
3. instrument：Balance, semi-automatic soxhlet type instrument (2055SOXTEC Manual Extraction Unit)
Step：Air-dried 3~5g of meat sample filter paper is claimed to wrap up and number.Filter paper is wrapped in 103~105 DEG C of baking ovens and dries 2h.
It moves into the extraction pipe of Soxhlet extractor and anhydrous ether is added, setting program (boiling 2h) recycles 103~105 after ether
10min is dried in DEG C baking oven, in drier after cooling 30min, weighing.
Fat (%)=[(W2-W1)/W] × 100%
In formula, W is air-drying sample weight (g), and W1 is fat collecting bottle weight (g) before extracting, and W2 is fat collecting bottle after extraction
(g)。
(8) longissimus dorsi muscle Contents of Amino Acids
Claim 3~5g of meat sample, accurately to 0.0001g, then carry out degreasing, after degreaser drying, crushes.Weigh sample powder about
0.1g is fitted into ampere bottle, and the 6mol/L hydrochloric acid hydrolysis of 10mL is added, sets and seals after freezing 1~2min in liquid nitrogen, it is placed on 110 ±
In 1 DEG C of thermostatic drying chamber, hydrolysis 22~for 24 hours.It is cooling, it mixes, all solution are transferred in cucurbit, are used in combination by open pipe
0.02mol/L HCl is rinsed ampere bottle 1~2 time, and cucurbit rotary evaporation vacuumizes, and water bath temperature is set as 65 DEG C, evaporation
It is extremely dry.The 0.02mol/L HCl of 20mL is pipetted in cucurbit, pipettes 1mL solution in bottle after dry matter in 25mL after sufficiently dissolve
Volumetric flask, with 0.02mol/L HCl constant volume.Upper machine analysis after taking 1mL to filter.0.200mL kilnitamin standard is drawn, pH is used
2.2 buffer is diluted to 5mL, this standard dilution concentration is 5.00nmol/50 μ L, the amino acidity scale as upper machine measurement
Standard, with the full-automatic automatic amino acid analyzer of A300 with the amino acid content of external standard method Specimen Determination liquid.
4, test growing and fattening pigs blood parameters commission Shaanxi Province's construction company hospital measurement.
