The objective of this study was to determine whether various sources of roughage in nutritionally balanced feedlot diets would evoke a stress response in sheep. A nutritional stress response test was performed on 20 ewes, randomly divided into four treatment…
Meat rabbits could provide a new avenue for agricultural development in South Africa, and flavonoids may be able to improve their live performance. This study investigated the effects of quercetin dihydrate (0 and 2 g/kg feed) on the growth parameters…
The effect of loading, transportation, lairage and slaughter conditions on bleed-out times, behavioural and physiological responses of Nguni and non-descript steers reared extensively on natural pastures was investigated. Twenty Nguni (NG) and 20 non-descript (ND) steers were loaded and transported…
This study determined the effect of space allowance on performance, carcass grade and physiological variables of pigs reared in sawdust fermentative pigsties. A total of 699 crossbred (Landrace × Yorkshire × Duroc) pigs were housed in sawdust fermentative pigsties and…
Eighteen beef heifers, representing the Bos taurus (Shorthorn), Bos indicus (Afrikaner) and intermediate (Bonsmara) types, were confined to a pen with floor space of 4,6 m2 per heifer. A similar number of heifers on the veld served as a control.…
The effect of different shelters, that is, a shade structure (3.5 m high) in a dry lot and a tie-stall barn in comparison to a dry lot with no protection against climatic conditions (rain and wind), on the milk pro¬duction…
The effect of a shade structure on some physiological parameters of lactating Dutch-type Friesian cows was determined over three consecutive summer periods. Plasma cortisol concentration of no-shade cows was significantly (P < 0.05) higher than that of shade cows during…
