The study assessed the effect of total replacement of maize with raw or heat-treated cassava tuber meal (CTM) on egg shelf life, welfare indicators, and physiological and carcass traits of laying jumbo quail hens. Two hundred and forty, six-week-old quail…
Nutraceutical plant products such as red grape pomace (Vitis vinifera L. var. Shiraz) contain potent antioxidants that could mitigate stress caused by high stocking density. An experimental feeding trial was conducted using a total of 720 densely-stocked (30 birds/pen) Ross…
Heat stress is a major challenge for dairy cows in summer. Sprinklers at feed bunks are commonly used to cool cows. These sprinklers use groundwater, which is becoming limited. There is a need to explore a more efficient use of…
The behaviour, welfare, and tibia characteristics of fast- and slow-growing chickens were evaluated in free-range and intensive production systems. A total of 720 birds of three strains were subjected to these systems after 21 days of rearing under the same…
During a broiler breeder trial with 3200 Cobb 500 hens, the effects of lighting treatment after 20 weeks’ feed allocation and of feed form on the length of time taken to consume the daily allocation of feed were measured. Pullets…
Performance, physiological and behavioural parameters of two groups of domestic chickens were compared. Chickens were raised in classical commercial conditions in buildings housing 12000 birds. One group acted as a control, while the environment of the other was perfused with…
