24/7 behaviour and welfare of giraffes
Giraffes are known for their remarkable sleeping patterns. While this has received ample scientific attention, and interesting differences in nocturnal behaviour between giraffe subspecies have been recently recorded, results of these studies are not always related to animal welfare. Especially now that 24/7 welfare concepts are being applied to zoos, a better understanding of sleep […]
Abstract: Giraffe nutrition study at the Wilds, Ohio
Captive management of giraffe (Giraffa camelopardalis) has been hampered because of health and diet issues. Specifically, giraffe often suffer from rumenacidosis, which can lead to compromised digestion and shortened lifespan. Additionally, many individuals suffer from urolithiasis, a blockage of stones in the urinary tract, which can lead to sudden death. Several studies have suggested zoo […]
Behavioural changes in dairy cows with lameness in an automatic milking system
There is a tendency worldwide for the automation of farms; this has included the introduction of automatic milking systems (AMS) in the dairy industry. Lameness in dairy cows is highly prevalent and painful. These impacts potentially affect not only animal welfare, but also farm economies. Three independent observational studies were carried out to assess the […]
Quantitative aspects of the ruminating process in giraffes (Giraffa camelopardalis) fed with different diets
Giraffes are ruminants feeding on fresh browse and twigs in the wild, but in zoos, their diet is mainly based on alfalfa hay, grains, and pellets occasionally supplemented by twigs and foliage. These diets, which differ in composition and digestibility, affect the behavior of the animals, tooth wear patterns, and chewing efficiency. We quantified several […]
