The influence of diet composition upon growth and development of Sandhill Cranes The influence of diet composition upon growth and development of Sandhill Cranes
Experiments were conducted to evaluate the effect of protein, metabolizable energy, and sulfur amino acid content of five diets upon growth and development of captive Florida Sandhill Crane (Grus canadensis pratensis) and Greater Sandhill Crane (G. c. tabida) chicks raised under controlled conditions. A high protein (32%) diet resulted in faster growth than that obtained when a lower...

Reduced mortality among young endangered masked bobwhite quail fed oxytetracycline-supplemented diets Reduced mortality among young endangered masked bobwhite quail fed oxytetracycline-supplemented diets
Two experiments were conducted to examine the effect of oxytetracycline-supplemented diets on mortality of young endangered masked bobwhite quail (Colinus virginianus ridgwayi). Inclusion of oxytetracycline at 200 g per ton in the feed for 6 weeks resulted in a marked, significant reduction in mortality of young masked bobwhite quail raised in captivity. Including the antibiotic in feed...

Influence of dietary protein and excess methionine on choline needs for young bobwhite quail Influence of dietary protein and excess methionine on choline needs for young bobwhite quail
Experiments were conducted with young Bobwhite quail (Colinus virginianus) to investigate the effect of differing dietary protein levels and nondetrimental amounts of excess methionine on choline needs. Growth and feed consumption of quail fed an adequate (27.3%) protein purified diet supplemented with 2000 mg/kg of choline were unaffected by increasing the level of excess methionine to...

Influence of protein level and supplemental methionine in practical rations for young endangered masked bobwhite quail Influence of protein level and supplemental methionine in practical rations for young endangered masked bobwhite quail
A study was conducted to examine the protein requirement of young endangered masked Bobwhite quail (Colinus virginianus ridgwayi). Five practical starting rations containing 24 to 32% protein were fed alone and supplemented with methionine for 5 weeks. Supplemental methionine significantly improved growth of quail fed diets containing 24 and 26% protein. Increasing the protein level...

Sea turtle distribution along the boundary of the Gulf Stream current off eastern Florida Sea turtle distribution along the boundary of the Gulf Stream current off eastern Florida
Aerial surveys, out to 222 km off the east coast of central Florida during August 1980, revealed that marine turtles were distributed in a narrow zone west of the Gulf Stream. Of 255 loggerhead turtles, Caretta caretta, only three were observed east of the western boundary of the Gulf Stream. Radiometric thermometry revealed that the waters occupied by most Caretta were markedly cooler...

Anarbylus switaki Murphy: An addition to the herpetofauna of the United States with comments on relationships with Coleonyx Anarbylus switaki Murphy: An addition to the herpetofauna of the United States with comments on relationships with Coleonyx
Anarbys switaki, a species previously known only from Baja California Sur, Mexico, occurs in eastern San Diego and southwestern Imperial Counties in California. In California, specimens tend to have continuous transverse bars on the body, are lighter in color, and more slender in body form than in southern Baja California. California populations appear to be confined to extremely rocky...
