Efeito das condições pré-abate sobre a qualidade da carne de suínos pesados

The objective of this study was to evaluate pig fasting time at the farm (FT= 9, 12, 15 or 18 hours) and pig position into the pig lorry compartment on pork quality through liquid drip loss (DLL), pH1 evaluated at 45 minutes post slaughter and pHu evaluated 24 hours post slaughter. One hundred ninety two females, weighing 133±11 kg, from two farms were used. Pig locations were evaluated on truck compartment considering front, middle and rear (TCL) position and top or botton decks (LUD). The following effects were considered in the statistical model: block (BL= farm), FT, TCL, LUD and the interaction between BL and FT. The FT affected significantly the pH1 of Longissimus dorsi (LD) muscle, and pHu of Semispinalis capitis (SC), Longissimus dorsi (LD) and Semimembranosus (SM) muscles. Fasting time at farm equal or shorter than 12 hours resulted in carcasses with lower pHu values at LD and SM muscles and fasting time above 15 hours resulted in higher pHu on SC. There were no observed effect (p>0.05) of the evaluated sources of variation on DLL. TCL affected pH1 of SC, LD and SM muscles, and pHu of LD and SM muscles. Pigs located in middle or rear position in the lorry had no difference in pH1 of the evaluated muscles. But pigs located in the middle position of the lorry had greater values of pHu on LD and SM. It is stated that pigs fasting time at farm need to be close to 15 hours in aim of obtain higher frequency of pHu values in the normal range (5.55

Fontes proteicas e idades de abate sobre a estrutura e ultraestrutura do intestino delgado de leitões desmamados

Two experiments (experiment 1 - conventional feeding and experiment 2 - feeding of the sows, starting at 109 days of pregnancy and during lactation, and the lactating piglets, with rations without soybean meal) were conducted to evaluate the effects of sources of protein (soybean meal-SBM, extruded semi-integral soybean-ESISB, and milk products-MP) on the intestinal morphology of piglets slaughtered at the 0, 5 and 15 days later at weaning. Twenty-seven piglets weaned with 25 days of age were used, being nine piglets slaughter in each slaughtering age. A 3 ×3 factorial (3 diets × 3 slaughtering ages) was studied, according to a randomized block design. The results showed that animals receiving SBM, presented lower values of villi height and villus: crypt ratio when compared to those that received ESISB or MP. The villi height and the villus: crypt ratio were not affected by the differential feeding of the sows and of the piglets before the weaning. The depth of the crypt was not affected by diets or slaughtering ages in none of the segments studied being, however, smaller in the duodenum and bigger in the jejunum and ileo of the animals of exp. 2. It was concluded that the SBM was the affected the height of the villi and the relationship villi: Crypt negatively after it weans. The intestinal morphology was more affected at five days, showing signals of recovering at 15 days after weaning and that the feeding of the sows did not affect the morphology of the segments of the thin intestine.
