carcass yield is important economical parameters for producers and contributors of meat science. in the present study, carcass yield and also the weight losses resulted post mortem until consumption were investigated. the mean values of cold carcass and hot carcass weight were 15.63 and 15.33, the mean value of cooling loss was 1.87% and average value of hot and cold efficiency were 41.44% and ...

Two studies were conducted to determine 1) the effect of post-mortem time before chilling on hot boned prerigor breast muscle water-holding capacity (WHC), and 2) post-mortem temperature effect on sarcomere length and drip loss of uncooked breast, and shear force and WHC of turkey breast muscle that is hot-boned, marinated, and cooked. In Study 1, the turkey breast muscle was excised immediatel...

Effects of dietary vitamin E supplementation on drip loss, cooking loss, and muscle fiber disruption in fresh beef loin steaks from Holstein and crossbred beef steers were studied. Nine Holstein steers and nine beef steers were fed a control diet and nine Holstein steers and eight beef steers were supplemented daily with 298 IU of vitamin E/kg of diet for 211, 232, or 252 d. Drip loss, cooking ...

One hundred seventy-seven pigs were used to determine the interaction effects of fasting and length of transport prior to harvest on pork muscle quality. The study design was a 2 x 2 x 3 factorial, which involved two genetic sources, fasting (F) or no fasting (N) of pigs 48-h prior to harvest, and three transport times (0.5, 2.5, or 8.0 h) on a semitrailer to the packing plant. Genetic source w...

in this study, ice-glazing process of frozen shrimp by chitosan was applied to protect the frozen shrimp from undesirable chemical and physical changes. the effects of 2% chitosan solution glazing on quality of whole, raw and cooked (without head, tail and shell) shrimps stored at -18±2ºc for 6 months were investigated and compared with water glazing, sodium metabisulfite treatment control. gla...

An experiment was conducted to determine the effects of betaine, pen space, and preslaughter handling method on growth, carcass traits, and pork quality of finishing barrows. For the growth trial, a 2 x 2 factorial arrangement of treatments was used: betaine (0 or 0.250%) and(or) pen space (m2/pig; adequate, 0.035 BW0.67 kg, or inadequate, 0.025 BW0.67 kg). Each treatment was replicated five ti...

In this study, a survey was conducted to both evaluate the consumers' general attitudes for purchasing and storing the raw chicken and determine the thawing practices used for defrosting frozen chicken at home. About 75% of the consumers indicated purchasing chicken meat at least once a week or more. Furthermore, the majority (82.16%) of those who stored at least a portion of the raw chicken st...

determination of the body composition weight due to the growing ostrich farms in iran is a beneficial subject. it is so important for dependent industries to know the effects of sex and slaughter conditions on carcass quality. in present study, the mean value for hot yield (55.93%) was higher than cold yield (54.70%). blood, feather and skin were evaluated as the maximum and the hide as the min...

Design/Methodology/Approach: Samples of non-stunned broiler breast meat (n=10) and stunned broiler breast meat (n=10) which have undergone the Halal slaughter method were analysed on the quality parameters of protein solubility, emulsion activity index, emulsion stability index, pH, water holding capacity (drip loss and cooking loss), texture (shear force textural analysis), meat colour (L, a, ...
