The present study sought to quantify the differences between maize-based (MS) and grass-silage-based (GS) diets in terms of their effect on the milk yield, milk fatty acid composition and antioxidant capacity in dairy ewes, and to test the hypothesis that…
A study was conducted to evaluate the fatty acid (FA) profile of subcutaneous adipose tissue and tailfat of two fat-tailed sheep breeds under identical feeding conditions. Twelve male lambs from two breeds, Sanjabi (n = 6), weighing 23.3 ± 0.48…
After a decline in value, ostrich feathers have again become an important part of the income of ostrich producers. Between 22586 and 22753 feather weights, as well as length and width measurements, were obtained from feathers harvested annually during the…
The aim of this study was to compare the health-related fatty acid (FA) profiles and health lipid indices in the raw milk of Simmental and Holstein-Friesian cows from an organic farm. The milk from Simmental cows had a significantly higher…
The objective of the trial reported here was to determine whether breast meat yield would improve in broilers reared on short daylengths if higher levels of dietary protein were fed. To that end, 3200 Ross 308 International broilers were reared…
Heat stress negatively affects the meat quality in broiler chickens, as indicated by lipid peroxidation. The aim of this study was to investigate the effects of 0.0, 2.5, 5.0 and 10 g sumac fruit powder/kg of the diet, along with…
Tools for the genomic evaluation of goats have generally lagged behind those for other species. However, the recent availability of the goat SNP50 consortium bead chip has marked a positive change for this small ruminant species. Polymorphic loci can differ…
Ten high-yielding cultivars of triticale obtained from a breeding group at the University of New England, harvested in 2008 and 2009, were assessed for nutrient composition and nutrient digestibility. The cultivars tested were AT528, H20, H127, H128, H157, H249, H418,…
Three hundred and thirty-six day-old male Cobb-500 broiler chickens were randomly allotted to seven dietary treatment groups. Twelve chicks were slaughtered on day 1 to obtain baseline data. There were six replicates of each treatment and eight chicks per replicate.…
This study aims to evaluate the quality of boar sperm that was refrigerated for 14 days at 17 ºC with three extenders. For this study, samples from four boars were collected twice a week using the gloved-hand technique. After collection,…
A trial was conducted to determine the effects on the performance of creep feeding suckling lambs and supplementing ewes that were grazing wheat stubble. Eight experimental units of South African Mutton Merino (SAMM) ewes and lambs were used in a…
The objective of this study was to determine the comparative changes in the monthly blood urea nitrogen (BUN) concentration, total protein (TP) concentration in blood serum and the body condition score of Nguni cows and heifers raised on sweetveld. Twenty-four…
Longevity is a major component of the breeding objective for dairy cattle in many countries because of its high economic value. The trait has been recommended for inclusion in the breeding objective for dairy cattle in South Africa. Linear models,…
The aim of the present study was to determine the phenotypic correlations of backfat thickness with meatiness traits and intramuscular fat, cholesterol and fatty acid composition in the longissimus muscle of pigs. For this study, 60 barrows and 60 gilts…
The aim of the study was to evaluate the effect of the duration (24 hours, 60 days and 120 days) of frozen storage (−20 ºC) on the fatty acid composition of meat from ostriches supplemented with linseed and rapeseed. The…
An in vitro study was conducted to determine the extent of melamine degradation in rumen liquor. Rumen liquor was collected from two ruminally cannulated Holstein cows on four separate dates, one week apart. Erlenmeyer flasks (250 mL) were prepared for…
The aim of the study was to evaluate the nutritional status of scavenging chickens by assessing the composition of their crop contents. The study was conducted on 288 free-ranging indigenous chickens from six adjacent rural villages in Venda region of…
The aim of the present study was to evaluate the effects of three feeds containing 6% oils: palm oil (PO), soybean oil (SO) and linseed oil (LO); and three calcium levels (NRC recommendation, 1.25% and 1.50%) on the fatty acid…
Weaning is associated with several stress factors and their effects on the piglet’s body are fairly well known. Thus, changes were estimated in certain serum and faecal parameters after weaning owing to dietary protein level, though essential amino acid (AA)…
The effects of production system on welfare traits, growth performance and meat quality of ducks were explored. A total of 120 newly hatched ducklings were randomly assigned to three groups: i) floor-reared system (FRS); ii) welfare-reared system (WRS) and iii)…
