Effect of polymorphism in the porcine cytochrome b5 (CYB5A) gene on androstenone and skatole concentrations and sexual development in Swedish pig populations The effects of cobalt and iodine supplementation of the pregnant ewe diet on immunoglobulin G, vitamin E, T3 and T4 levels in the progeny Caecal fermentation characteristics, blood composition and(More)
Wild and domestic ungulates modify their behaviour in the presence of olfactory and visual cues of predators but investigations have not exposed a domestic species to a series of cues representing various predators and other ungulate herbivores. We used wolf (Canis lupus), mountain lion (Puma concolor), and mule deer (Odocoileus hemionus) stimuli (olfactory(More)
Social learning can be of critical importance to cattle grazing rangeland environments with high variability of food resources across space and time. Experienced individuals can greatly facilitate foraging decisions (what to eat and where to eat) of naïve peers in such settings. We conducted an experiment with cattle to investigate strength and persistence(More)
This paper reviews the literature and reports on the current state of knowledge regarding the potential for managers to use visual (VC), auditory (AC) and olfactory (OC) cues to manage foraging behaviour and spatial distribution of rangeland livestock. We present evidence that free-ranging livestock use these sensory cues to make decisions about foraging,(More)
