This study was conducted to determine the status of Salmonella during the processing of ostriches to ostrich meat and products. When a total of 1429 samples, collected from fillet, liver, gizzards, blood meal, skins, heart, faeces, large and small intestines,…
The essential amino acid composition of carcasses from South African Mutton Merino ram lambs fed a standard diet was investigated. Twenty lambs were randomly allocated to four pre-assigned average slaughter weights (30, 35, 40 and 45 kg live weight). The…
Twenty Dohne merino wethers with an average mass of 52 kg, were used to study the effect of varying the fibre content of the diet on differences in ruminal concentrations of volatile fatty acids (VFA) and the partial digestion of…
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 effect of the halothane gene on processed pork characteristics was investigated using the meat from 59 Landrace x Large White pigs of known halothane genotype (NN = 31, Nn = 17, nn = 11). The backs and hams were…
The Kuri is a rare, little known breed of cattle of the Hamitic Longhorn (Bos Taurus longifrons) type which is found on the islands and shores of Lake Chad Basin in the area covering the common borders of Cameroon, Chad,…
The object of this study was to determine the influence of different stocking rates (viz. 2, 4, 6 & 8 sheep /ha for a six-month period) on the performance of Dohne merino ewes grazing Digitaria eriantha (Smuts finger grass) pasture…
Small-scale farmers in the rural areas of South Africa do not have milling and mixing facilities at their disposal. A study was conducted to quantify the production as well as the energy and nitrogen metabolism of pigs when fed a…
Grazing trials were established at two sites in the semi-arid savanna (Lowveld) of KwaZulu-Natal. The sites differed initially in rage composition. Llanwarne was dominated by Themeda triandra, Panicum maximum and P. coloratum and Dordrecht by Urochloa mosambicensis, Sporobolus nitens and…
Testes diameter of 110 Merino ram lambs was measured at 100, 260 and 550 days of age. At 80 days of age the LH response to exogenous GnRH was determined in these rams. During the breeding season at 18 months…
The aim of this study was to determine the potential of Smuts finger grass as summer grazing for sheep on two soil types at different stocking rates and fertilization levels. The four seasons during which the trial was executed, were…
The influence of the pre-ovulatory oestradiol-17ß (E2) surge on yield of viable embryos was studied in 28 oestrus synchronized SAMM ewes. Ewes were super ovulated either with FSHo (88 units in 6 divided doses) or PMSG (1200 IU). Blood samples for…
The effect of immunization against oestradiol-17â (E2) on fertilization rates and of human chorionic gonadotrophin (hCG) in reducing the proportion of unovulated follicles from super ovulated ewes was examined. Forty South African Mutton Merino ewes were divided into four treatments…
Sixty-six grazing beef cows at Armoedsvlakte were supplemented per fistulam with different levels of phosphorus (P) from 1984 to 1989. Supplementation was provided according to a 3 x 2 factorial of three levels of P (Low, Medium and High), in…
