Introduction of gum Arabic and guar to the diet of captive black-tufted ear marmosets
Gum plays a significant role in the feeding ecology of wild callitrichids and thus is also supplemented to several primate species in captivity. However, little is known about the feeding habits of black tufted-ear marmosets (including gummivory), in both wild and captive populations. Therefore, the present study introduced gum to the diet of adult captive […]
Effects of origin, experiences early in life, and genetics on bitterweed consumption by sheep
Bitterweed is one of the most detrimental poisonous plants to sheep production in west central Texas. Sheep typically avoid the plant unless alternative forage is limited. When consumption does occur, some flocks and individuals are able to consume bitterweed and avoid toxicosis. Our objective was to determine the importance of site of origination (long-term exposure), […]
Effect of concentrates restriction on feed consumption, diet digestibility, and nitrogen utilization in captive Asian elephants (Elephas maximus)
In order to study the effect of concentrates restriction on feed consumption, diet digestibility, and utilization of nitrogen in captive Asian elephants (Elephas maximus), two feeding trials were conducted on three juveniles, four sub-adults, and three adults. During trial I, the conventional zoo diets of juveniles, sub-adults, and adult contained 22, 17, and 16% of […]
