ABSTRACT This study aimed to characterize carcass, meat quality, sensory and textural parameters, as well as muscle fiber types from 16 Moura pigs, as a local pig raised in outdoor production system, and evaluate differences with 16 conventional commercial (CC) pigs, raised intensively, representing the principal pork type, widely available in national market. Carcass measurements, liquid loss and cooked pork texture tests, proximal composition analysis of pork and backfat, and sensory evaluations with 104 pork consumers were carried out. The […]

The objective of the experiment was to study the carcass physical composition and meat qualitative characteristics of different categories of Charolais cattle, feedlot finished. Nine steers (ST), ten heifers (HE), with average age of 20 months, and ten cull cows (CO) with average age of 87 months, taken from the same herd, were used. Diet contained 13% of crude protein for ST and HE and 10% for CO, with roughage:concentrate relation of 50:50, on a dry matter basis. The animals […]

A Bayesian marker-free segregation analysis was applied for the estimation of variance components and to search for evidence of segregation genes affecting two carcass traits: intramuscular fat (IMF), %, and backfat thickness (BF), mm ; and one growth trait: body weight gain (LG) from 25 to 90 kg, approximately, g/day. In this study, 1,257 animals from the F2 design produced by breeding among pigs Meishan (male) and Dutch Large White and Landrace lines (female) were used. In animal breeding, finite […]
