Prediction of Drip Loss and Ultimate Ph in Pork Semimembranosus by the Nitfom
نویسندگان
چکیده
Most of the NIR spectrometers available are not suited for on line measurements in slaughterhouses. The aim of the study was to test the ability of a device dedicated to industrial measurement (NitFom, Frontmatec) for prediction of drip loss and ultimate pH. A calibration model fitting was satisfactory (drip loss, R2=0.59 and pHu, R2=0.70) and the prediction accuracy levels for drip loss were similar to calibration results found with the Labspec4, a laboratory Vis-NIR spectrometer (NitFom, rmsecv=1.5% and Labspec4, 1.7%). This study revealed that prediction of drip loss by NIRS could be a good alternative to measurement of ultimate pH for drip loss sorting.

The influence of diets supplemented with conjugated linoleic acid, selenium, and vitamin E, with or without animal protein, on the quality of pork from female pigs.
Pork from the LM and semimembranosus muscle (SM) of 59 female Duroc-cross pigs with a mean carcass weight of 80.1 kg (SD = 3.2) were assessed for quality. The pigs were grown on diets containing either animal and plant products (the animal group) or plant products only (the plant group), with or without a supplement (0.31% of the diet) containing extra CLA, selenium, and vitamin E. The 45-min p...

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...

The gene (Cbg) encoding cortisol-binding globulin (CBG) has been proposed as a candidate gene to explain genetic variation in cortisol secretion and carcass composition in pigs. The objective of this study was to evaluate the association between CBG and pork quality in 5 European breeding lines, Piétrain, Large White (LW), and Landrace purebred lines, a Duroc synthetic line, and a Meishan (MS) ...

The effects of the carbohydrate composition of finishing diet (fed from 80 to 107 kg of body weight) and the length of pre-slaughter fasting on pork quality were studied in a 2 × 2 factorial experiment with 80 crossbred pigs. The control finishing diet was based on barley and soybean meal, and the fibrous finishing diet was based on barley, barley fibre, faba beans, and rapeseed cake. These die...
