The antioxidant enzyme, copper zinc superoxide dismutase (CuZnSOD) plays an important role in protecting tissues from damage by reactive oxygen species (ROS) reactions. The objective of this investigation was to determine the CuZnSOD mRNA level as an indicator of CuZnSOD…
The effect of sex and the supplementation of the prebiotic, mannan oligosaccharides (MOS), the acidifier, calcium propionate (CPr) or their combination in the feed of Japanese quail (Coturnix japonica) on their performance and carcass quality was examined in this experimentation…
Forty turkeys were allocated to five groups of eight birds each. One (control) was fed a basal diet while the others were fed diets supplemented with either olive leaves at 10 g/kg, rosemary at 10 g/kg, α-tocopheryl acetate at 150…
This study aimed to determine the fatty acid and composition and cholesterol concentration of horsemeat, and to evaluate its taste acceptability by the Brazilian population. Horsemeat samples were obtained from a Paraná State slaughterhouse. The chemical composition revealed a low…
Fifteen young Holstein Friesian bulls (18 mo of age) were divided into three groups of five. All groups were fed a diet consisting of 60% concentrate and 40% roughage. The control (C) group received a mixture of dry meadow hay,…
Several biologically dependent quality characteristics of meat (appearance and palatability) have been researched extensively in South Africa and some of these findings are discussed briefly in this article. Sound production and management practices may be used to manipulate the many…
This experiment was conducted to compare carcass and meat quality traits, and muscle fibre characteristics in the longissimus muscle of the Landrace [an European pig breed] and the Lantang [a Chinese native pig breed] at the ages of 60, 90…
A sample of 104 lamb and mutton carcases was selected on the market at an abattoir in three age groups and four mass classes representing five of the six fat classes of the classification system. The loin cut of the…
Impala (Aepyceros melampus) constitute one of the most commercially important species in game farming in South Africa. The purpose of this study was to compare the effects of day and night cropping on the meat quality characteristics of impala. Emphasis…
The effect of divergent selection for ewe multiple-rearing ability over a 15-year period on mutton quality was examined on the M. longissimus dorsi and M. semimembranosus of entire rams (R) and ewes (E) derived from two Merino lines. The selection…
This study details the slaughter traits of lambs born from a terminal crossbreeding experiment that involved five Merino type dam lines crossed with Dormer and Suffolk sires. Dam lines included dual purpose types; South African Mutton Merino (SAMM), Dohne Merino,…
Simmentaler cross (SX), Bonsmara cross (BX) and Nguni (NG) steers were raised on natural sweet veld pastures and slaughtered at 18 or 30 months of age. Slaughtering occurred at the end of the wet summer season. Live weight and carcass…
The effects of production system (feeding regime and time on feed) on growth performance, yield and economics and the effects of feeding regime, pre-slaughter treatment and electrical stimulation on meat quality were evaluated. Sixty Bonsmara steers were divided into three…
The effect of the halothane gene on certain growth and meat quality characteristics were investigated by comparing the three known halothane genotypes (NN, Nn, nn), fifty nine Landrace x Large White pigs (gilts = 25, castrates = 34; NN =…
The aim of this research was to study the effect of high-maize diets and pelleting on the accumulation of lutein pigments and appearance of the subcutaneous fat in Dorper and SA Mutton Merino wethers. High and medium energy maize diets…
Animals, maintained from birth on a higher and lower fibre diet, were slaughtered when postnatal growth curves flattened off. Males tended to be larger than females. The meat of females tended to have higher lipid (9.2 g/100 g fresh mass)…
Malignant hyperthermia (MH) genotype, as expressed by the halothane genotype, was determined on a random sample of 100 pigs originating from the Western Cape. The pigs were slaughtered to investigate the effect of MH genotype on certain carcass characteristics and…
