  • Issue: 3
  • Volume: 13
A.S. Faure, D.A. Boshoff and F.J.L. Burger Page: 157 - 160

The oestrous cycles of Karakul ewes were synchronized during both the breeding (February) and non breeding season (October) using either whole or halved sponges, in combination with either subcutaneous or intravenous administration of PMSG. At the time of sponge withdrawal,…

Production parameters of the impala, Aepyceros melampus

  • 1983
  • Issue: 3
  • Volume: 13
N. Fairall Page: 176 - 179

From a game farming point of view, the impala is quantitatively the most important animal in the Bushveld areas of South Africa. However very little published data are available on the productive capacity of this animal. In a long-term study…

Ovine wet carcass syndrome of unknown aetiology

  • 1983
  • Issue: 3
  • Volume: 13
R.M. Brock, J.P.J. Joubert, A. Hattingh, G. Mitchell, S.J. Newsholme, R.R. van der Veen, H.S. Hofmeyr, E.A.N. Engels, H.B. Groenewald and P. Hunter Page: 194 - 195

A condition of unknown aetiology, known as 'the wet sheep carcass syndrome' has led to the loss of about R500 000 as a result of the condemnation and trimming of carcasses, during the past 2 years. An affected carcass has…

Estimating phosphorus intake by grazing sheep

  • 1983
  • Issue: 3
  • Volume: 13
P.C. Belonje and A. van den Berg Page: 195 - 198

Estimating phosphorus intake in grazing sheep is difficult since hand-picked samples of forage do not represent actual intake. Results showed that faecal P did reflect dietary P levels. A minimum of 30 sheep should be sampled to obtain an error…

Effects of hot environments on bone growth in rats

  • 1983
  • Issue: 3
  • Volume: 13
T. Kawashima and H. Vano Page: 200 - 201

The physio-chemistry and endocrinology of bone growth was studied in rats housed under different temperature conditions. Bone lengths did not change significantly but bone widths and densities became significantly smaller in rats kept at 34 °C.The depression of bone alkaline…

Urea-ensiled rice straw as a feed for cattle in Thailand

  • 1983
  • Issue: 3
  • Volume: 13
Parnich Tinnimit Page: 203 - 205

Rice-straw was ensiled with a 5-6% urea solution for 3 weeks before being fed. Cattle fed with urea-ensiled rice straw alone can maintain weight. However, to obtain a daily weight gain of 300-450 g in Holstein Friesian heifers (8-12 months…

The influence of inoculum source on in vitro digestibility

  • 1983
  • Issue: 3
  • Volume: 13
W. van Hoven and E.A. Boomker Page: 207 - 209

A series of in vitro incubations were performed in which a constant substrate (antelope cube) was used and only the inoculum source was varied. With an inoculum obtained from 7 different wild ruminants, gas production rate varied considerably and was…

A comparison of rumen function in four Kalahari ungulates

  • 1983
  • Issue: 3
  • Volume: 13
W. van Hoven Page: 209 - 211

The ratio's of reticulo-rumen volume to body mass were determined for all four species in addition to rumen pH, fermentation rate and VFA concentration. Information on rumen and faeces dry-matter percentage is also reported. Only the blue wildebeest exhibited a…

Digestibility of the same diet in cattle and sheep

  • 1983
  • Issue: 3
  • Volume: 13
P. van Rooyen and F.J. van der Merwe Page: 211 - 212

The question is posed of the applicability to cattle feeding, of digestibility data obtained with sheep. An experiment is described where the same high concentrate diet was fed at three levels, equalised per kg body mass between species. In energy…

Rumen fermentative activity in the goat and sheep

  • 1983
  • Issue: 3
  • Volume: 13
R. Cabrera, P. Villarroel, E. Vial & A. Castillo Page: 213 - 215

Measurements of rumen function were made on sheep and goats fed the same range of diets. Differences between sheep and goats with respect to gas production rate, glucose fermentation, nitrate reduction capacity, total VFA production and individual VFA concentration were…
