Materials and methods: A total of 200 pigs (129 gilts and 71 barrows) were subjected to two different lairage times at the slaughterhouse, short lairage (3 hours) and long lairage (12 hours), after a short journey (15 km, 20 minutes) by road from farm to abattoir. Blood samples were collected at the beginning of the slaughter line to determine stress markers: acute phase proteins (haptoglobin, ...

Assessment of muscle mass is important for evaluating muscle function and rehabilitation outcomes. Ultrasound has recently been successfully used to estimate muscle mass in humans by measuring muscle thickness. This study attempted to standardize procedures for measuring femoral muscle thickness ultrasonographically, as well as quantify the reliability and validity of ultrasound evaluations of ...

This study analyzed the effect of finishing diet supplementation with herbal probiotic preparation, ascorbic acid, and allicin on mortality rates pigs, longissimus lumborum (LL) semimembranosus (SM) muscle quality, including levels cholesterol, macroelements microelements. The experiment was carried out 3614 hybrid pigs (equal share gilts barrows), offspring PIC410 boars DanBred sows (Landrace-...

The contributions of replacing rye-grass (Lolium spp.) hay with banana (Musa acuminata) by-products on carcass and tissue characteristics, pH color, in the Canary hair sheep breed were studied. Twenty-two lambs an initial live weight 14.8 ± 2.5 kg individually housed fed two different diets for 58 days: first group (experimental diet) received as forage a mixture fresh composed by leaves pseudo...

Unlike the mammalian fetus, development of the avian embryo is independent of the maternal uterus and is potentially vulnerable to physiological and environmental stresses close to hatch. In contrast to the fetus of late gestation in mammals, skeletal muscle in avian embryos during final incubation shows differential developmental characteristics: 1) muscle mobilization (also called atrophy) is...

The decline in isometric force, swelling of sarcoplasmic reticulum and loss of desmin was measured in semimembranosus lateralis muscle of male Wistar rats immediately after a short series of brief (500 ms) maximal isometric contractions. For the active muscle, the series ended below (protocol A) and just over muscle optimum length (protocol AA). In one protocol, the muscle remained passive and ...
