Effects of nutritionally-mediated increases in the plasma ammonia concentrations of donor ewes on the in vivo and subsequent in vitro development and metabolism of their embryos
(University of Aberdeen, 1994)A review of the literature indicated that high levels of protein in ruminant diets can lower fertility. Ammonia from proteins that are rapidly degraded by the rumen microbes has been suggested as the factor that may affect ... -

Effects of post-weaning nutritional conditions on isowean pigs
(American Society of Agricultural and Biological Engineers, 1999)This study quantifies the responses of isowean pigs to post-weaning nutritional conditions as may be encountered during extended shipment. PIC breeding stock pigs at 8 to 12 days of age (3.5 to 4.0 kg body weight) were ... -
Effects of pre-treatments methods on the germination of pod mahogany (afzelia quanzensis)and mukusi(baikiaea plurijuga)seeds
(International Journal of Innovative Research in Science, Engineering and Technology, 2014-01)Seed pre-treatments (mechanical, concentrated sulphuric acid for 3, 6, 9 and 12 minutes, hot water treatments for 3, 6, 9 and 12 minutes) were carried out to overcome seed dormancy of Afzelia quanzensis and Baikiaea plurijuga ... -
Effects of real exchange rate and gross domestic product on yam exports in Ghana
(Botswana University of Agriculture & Natural Resources, 2011)The objective of this paper was to evaluate the responsiveness of Ghana’s fresh yam export supply to real exchange rate and national income (GDP) with the use of time scries data from 1990 to 2004. Data collected from ... -
Effects of safflower (Carthamus tinctorius L.) genotypes on growth, development, yield and yield components, and oil content and yield
