The effect of Moringa oleifera leaf meal supplementation on tibia strength, morphology and inorganic content of broiler chickens
(South African Society for Animal Science, 2014-08-13)
This study was conducted to assess the effects of dietary Moringa oleifera leaf meal (MOLM) supplementation as a possible alternative to antibiotic growth promoters on bone breaking strength (BBS), tibia bone morphology ...
Influence of frozen storage on the fatty acid composition of ostrich meat enriched with linseed and rapeseed
(South African Society for Animal Science, 2015-05-16)
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 ...
The effect of different dietary vitamin and mineral levels on certain production parameters, including egg shell characteristics of breeding ostriches
(South African Society for Animal Science, 2014-08-24)
Earlier studies on breeding birds indicated no effect of dietary energy-content on feed intake. This observation is contradictory to results for other animals and/or poultry where feed intake decreases with an increase in ...
Carcass traits and cutting yields of entire and immunocastrated pigs fed increasing protein levels with and without ractopamine hydrochloride supplementation
(American Society of Animal Science, 2015)
The objective of this study was to determine the effects of increasing balanced protein, with and without ractopamine hydrochloride (RAC), in the finisher diets of immunocastrates on their carcass cutting yields and ...
The effect of rumen inert fat supplementation and protein degradability in starter and finishing diets on veal calf performance
(South African Society for Animal Science, 2003)
Thirty six Holstein bull calves were divided into six groups to determine the effect of protein degradability and rumen inert fat supplementation in starter and finishing diets on nutrient digestibility and veal production. ...
Anti-nutritional factors in canola produced in the Western and Southern Cape areas of South Africa
(South African Society for Animal Science, 2007)
ABSTRACT: The development of low erucic acid, low glucosinolate cultivars of canola seed has led to the availability of a feed ingredient with considerable potential to replace soyabean meal in diets for all classes of ...
Post-mortem changes in the physical meat quality characteristics of refrigerated impala M. longissimus dorsi
(South African Society for Animal Science, 2004)
The effect of aging the M. longissimus dorsi of 13 impala at 4ºC over a ten-day period was investigated. Large variation between animals was observed for the percentages drip and cooking loss as well as for the CIELab ...
Influence of reproduction traits and pre-weaning growth rate on herd efficiency of different beef breed types in an arid sub-tropical environment
(South African Society for Animal Science, 2006)
ABSTRACT: The efficiency of Simmentaler cross (SX), Bonsmara cross (BX), Afrikaner (AF) and Nguni (NG) cowherds to produce weaner calves under natural sweetveld conditions was investigated. The respective cowherds were ...
Effect of slaughter age and breed on the carcass traits and meat quality of beef steers finished on natural pastures in the arid subtropics of South Africa
(South African Society for Animal Science, 2007)
ABSTRACT: 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. ...
Effects of post mortem temperature on rigor tension, shortening and pH in ostrich muscle
(South African Society for Animal Science, 2008)
ABSTRACT: Fully developed rigor mortis in muscle is characterised by maximum loss of extensibility. The course of post mortem changes in ostrich muscle was studied by following isometric tension, shortening and change in ...
