Red deer (Cervus elaphus) exhibit specific behaviour during the rutting season, which may have an impact on the safety on cervid farms, both due to aggressive interactions between animals and the safety of people staying there, such as staff and…
The aqueous ammoniation of wheat straw by urea, as affected by temperature and moisture level, was studied in a 4 x 2 x 6 factorial experiment. Treatments included temperatures of 4, 14, 24 and 35 °C, moisture levels of 250…
The effect of temperature, moisture level and treatment period on the ammoniation of wheat straw by 75 9 urea per kg wheat straw was investigated in a 4 x 2 x 6 factorial experiment. Independent variables included temperatures of 4;…
This study deals with the effects of different hatcher temperatures on hatching traits in modern commercial broiler eggs during the last five days of incubation. The hatching eggs were obtained from a 52-wk old (Ross 308) flock. All eggs were…
A study was conducted to assess the effects of varying storage temperature and relative humidity (RH) conditions, and feed preservatives (a mixture of Mold-Zap (a fungal inhibitor) and Banox E (an antioxidant)) on performance, visceral organ weight, serum biochemistry and…
Simulation modelling is an active part of animal nutrition which relies on mathematical functions to predict the performance of an animal. The Gompertz equation is one such function that is simple, but fits animal growth data well, and when used…
Sex, age and pre-slaughter conditioning effects on pH, temperature, colour and tenderness properties of M. semimembranosus (SM) of indigenous South African goats were investigated. Sex and age had no significant effect on pH. However, female goat carcasses cooled significantly slower…
The study was conducted to investigate the effects of sex, age and pre-slaughter conditioning on post-mortem pH, temperature and glycolytic metabolite concentrations in M. longissimus thoracis (LT) of indigenous South African goats. Three hours post-mortem, the 2-teeth group had the…
The productive performance of major genes for feather reduction (naked neck and frizzle) and body size reduction (dwarf) in a dual-purpose layer strain was evaluated in the subtropical coastal region of southeast Africa (Maputo, Mozambique). The experimental material consisted of…
Batches of 60-65 ostrich eggs were incubated in electronic incubators at 36.09, 36.5 and 37.3°C. The proportion of live chicks hatched relative to eggs set at 37.3°C (22/65 = 0.338) was impaired (p < 0.05) relative to those incubated at…
