3.2 Carcass and meat quality trait: The laen meat percentage of finished pigs in Yorkshire, Landrace, Duroc, Landrace X Yorkshire, Yorkshire X Landrace and Duroc X (Landrace X Yorkshire) improved 1.70, 4.80, 3.70, 4.0, 2.60, 8.6 percentage respectively from 2001 to 2003; and the backfat thickness decreased 0.6, 4.1, 3.3, 6.0, 10.0 7 & 8.8mm respectivelyly.
20 American strain Rex rabbits were slaughtered to study the characteristics and correlations of carcass and meat quality. The results showed: the average weight,commercial skin weight,dressing percentage,right hind leg weight,length and circumference length were 2.533 kg,0.410 kg,60.70%,0.182 kg,30.69 cm and 18.04 cm respectively about 150 days.
The results show as follows: Compared with contrasts, white yak’s meat quality is better. It has the characteristics with higher protein(21.87g/100g, P<0.05), lower fat(1.79 g/100g,P<0.05) and abundant mineral materials,especially iron (6.60 mg/100g,P<0.01).
1. An experiment was conducted using a total of 288 day-old Arbor Acres (AA) male broilers to study the effect of supplemental manganese (Mn) levels (0, 100, 200, 300, 400 or 500 mg/kg ) on growth performance, carcass traits, meat quality and relative enzyme activities in abdominal adipose tissue of the broilers.
Under same extensive grazing conditions,six hybrids of Boat goat with Nanjiang Yellow goat(BN,3♂、3♀)and six contemporary Nanjiang Yellow goat(NN,3♂、3♀)are slaughtered at eight months age. The analysis of meat quality show that the meat of BN has the virtue of fine-texture and tenderness.
When the amount of CP reduced four or six percent as compared to the standard,the body weight gain and slaughtering performance reduced significantly(P<0.01),the meat quality was not affected significantly(P>0.05).
Two hundred and forty one-day-old male broiler chicks were randomly allotted into four dietary treatments with different(0 %,0.25 %,0.5 % and 1.0 %)conjugated linolec acids(CLA)levels to examine the effects of CLA on carcass composition and meat quality in broiler chicks. Each treatment had 6 replicates with 10 birds each.
Meat quality of pigs is dependent on biochemical and biophysical processes in the time course post mortem (p.m.) and is associated with the intracellular Ca2+ homeostasis.
Price effects were significant, but with a positive mean and a large standard deviation, indicating that, for many consumers, price may act as an surrogate indicator of veal meat quality.
In general, heritability estimates for production and meat quality traits were higher than those for osteochondral lesions.
Data on on-farm traits (daily weight gain, percent premium cuts, and backfat) and on station-tested traits (daily weight gain, feed conversion ratio, meat quality, and osteochondral lesions) were available on 3,918 and 303 animals, respectively.
The importance of reducing the stress resulting from handling procedures (capture, restraint, transport) before the slaughtering of animals is highlighted, due to its adverse effects on meat quality.
