Die invloed van monensin op karkas- en woleienskappe van Merinolammers
The effect of monensin on carcass and wool traits of Merino lambs. Forty Merino lambs were used to determine the effect of monensin (20 mg/day) on carcass and wool traits when fed at two energy levels. Monensin improved feed efficiency…
The influence of age and generation number of the Döhne Merino on different wool production traits (Short communication)
Age had a significant (P ≤0,05) influence on greasy fleece mass and clean fleece mass. The staple length, fibre density and bodymas≤s were influenced highly significantly (P ≤5 0,01). Generation number had a significant (P ≤…
Effects of sodium chloride on sheep. 1. Diet composition, body mass changes and wool production of young Merino wethers grazing
Supplementary salt (NaCI) and crude protein (CP) were provided to young Merino wethers grazing native pasture. Twenty-eight wethers were divided into 7 groups and given the following supplements daily via rumen cannulae: 0, 5 (Control), 15 and 30 g NaCl;…
Feeding potential of summer grain crop residues for woolled sheep in the south-eastern Transvaal Highveld I. Availability of cro
In a two-year study, the value of crop residues of lupins, dry beans, soybeans, sunflower, sorghum and maize for wintering sheep was evaluated. The amounts of residues arid weeds present at the start and end of grazing were estimated by…
The potential of maize crop residues for wintering sheep on the eastern Transvaal Highveld
Maize crop residues were grazed at three stocking rates, viz. 6, 9 and 12 sheep/ha, for about three months. Total DM yield of the maize crop was about 7500 kg / ha, and consisted of 38,5% grain and 61,5% residues.…
Comparison of productive and reproductive efficiency of Afrino, Dorper and Merino sheep in the False Upper Karoo
The productive and reproductive performance of, as well as income generated by Afrino, Dorper and Merino sheep at two localities in the False Upper Karoo region were evaluated. A total of 1242 ewe reproductive records was available, while data of…
Studies on small ruminant breeds with inherent differences in fibre production and ewe productivity 1. Relationship between ewe
Ewe productivity, as affected by varying wool production potential in different environments was studied in three woolled sheep flocks. Production and reproduction data collected in the Carnarvon Afrino Flock (AC) between 1979 and 1992, as well as data of the…
