Development of conditioned taste aversion to Mascagnia rigida in goats Desenvolvimento de condicionamento aversivo ao sabor de Mascagnia rigida em caprinos

open access: yesPesquisa Veterinária Brasileira, 2008
The aim of this study was to determine whether goats could be averted from consuming Mascagnia rigida, a toxic plant found in the semiarid region of northeastern Brazil. Fourteen male goats not previously familiarized to M. rigida were randomly allocated

Diet selection of sheep shifted from quality to quantity characteristics of forages as sward availability decreased

open access: yesAnimal, 2022
Understanding the dynamic inter-relationship between grazing animals and the pasture sward is critical for sustainable grazing management. A field study was conducted to investigate the relationships between the quantity and quality characteristics of ...

Does feeding area restriction inhibit social learning of toxic weed ingestion in cattle?

open access: yesAnimal, 2010
Social learning from peers can trigger herd-wide intoxication with white locoweed (Oxytropis sericea), an alkaloid-synthesizing herbaceous legume that grows on rangelands of western North America.

Application of a high‐resolution animal‐borne remote video camera with global positioning for wildlife study: Observations on the secret lives of woodland caribou

open access: yesWildlife Society Bulletin, 2012
For many species of animals, obtaining basic life‐history data is difficult and even some common aspects, such as diet choice, remain unknown. To overcome this problem, we deployed what is, to our knowledge, the first successful application of a ...

Feeding Response to Tea Saponin in Chicks Given Diet Selection

open access: yesThe Journal of Poultry Science, 2001
In order to evaluate the involvement of taste in the decreased feed intake due to tea saponin, the preference for a diet containing saponin or cholesterol was studied in chicks given diet selection.

Effects of physical form and stage of maturity at harvest of whole-crop barley silage on intake, chewing activity, diet selection and faecal particle size of dairy steers

open access: yesAnimal, 2010
This study examined the effects of physical form and stage of maturity at harvest of whole-crop barley silage (WCBS) on feed intake, eating and rumination activity, diet selection and faecal particle size in dairy steers.

Hamiltonian patterns of age-dependent adaptation to novel environments.

open access: yesPLoS ONE, 2020
Our intuitive understanding of adaptation by natural selection is dominated by the power of selection at early ages in large populations. Yet, as the forces of natural selection fall with adult age, we expect adaptation to be attenuated with age ...

Evaluation of n-alkanes and their carbon isotope enrichments (d13C) as diet composition markers

open access: yes, 2011
Plant cuticular n-alkanes have been successfully used as markers to estimate diet composition and intake of grazing herbivores. However, additional markers may be required under grazing conditions in botanically diverse vegetation.

SUPPLEMENTAL ACTIVATED CHARCOAL AND ENERGY INCREASE INTAKE OF MEDITERRANEAN SHRUBS BY SHEEP AND GOATS [PDF]

open access: yesPoljoprivreda, 2008
Utilization of the Mediterranean shrubby vegetation is often limited by secondary compounds, such as terpenes, which at too high concentrations can adversely affect forage intake and animal health.

Expression of conditioned preference for low-quality food in sheep is modulated by foraging costs

open access: yesAnimal, 2015
Past positive experiences can increase herbivores’ motivation to eat low-quality foods. However, this is not always translated into a higher preference for low-quality foods in choice tests among foods of higher nutritional quality.
