Blood chemistry and hematocrit of captive and wild canvasbacks Blood chemistry and hematocrit of captive and wild canvasbacks
Blood chemistry and packed cell volume (PCV) did not vary among groups of captive canvasbacks (Aythya valisineria) maintained ad libitum on 5 diets varying in metabolizable energy (ME) and protein. Ducks fed low quality diets increased their consumption so that all ducks were obtaining similar amounts of energy and protein. Some variables, including cholesterol, were found to differ...

Influence of nutrients on feed intake and condition of captive canvasbacks in winter Influence of nutrients on feed intake and condition of captive canvasbacks in winter
Dramatic changes in the food habits and distribution of canvasbacks (Aythya valisineria) in Chesapeake Bay during the 1970's generated a need to evaluate the nutritional value of food items and the requirements of this species on its wintering grounds. Groups of captive canvasbacks were maintained ad libitum on 5 diets during the winters of 1978-79 and 1979-80 to evaluate the effects of...

Seasonal influence of nutrients on the physiology and behavior of captive canvasbacks (Aythya valisineria) Seasonal influence of nutrients on the physiology and behavior of captive canvasbacks (Aythya valisineria)
Captive canvasbacks (Aythya valisineria) were maintained ad libitum on five diets during the winters of 1978-79 and 1979-80 to evaluate the effects of varying protein and energy levels on feed intake and condition. Diets were formulated to simulate either a natural diet high in invertebrates or one high in vegetation. Two diets low in protein and energy simulated stress diets. Feed...
