Sources of calf wastage in the University of Arkansas Agricultural Experiment Station (Fayetteville) herds


, : Sources of calf wastage in the University of Arkansas Agricultural Experiment Station (Fayetteville) herds. Dissertation Abstracts International 40B(3): 1078-1079

Between 1952 and 1977 there were 5830 calvings and 563 deaths in the Arkansas AES beef herd. The main source of wastage was stillbirth (209 animals). Among the 329 calves born alive, the major causes of death were: found dead (30%), diarrhoea (17%), acorn poisoning (10%), pneumonia (8%), abnormal (6%), Johne's disease (5%), and bloat (3%), Deaths due to neonatal diarrhoea in beef calves occurred mainly in calves 2-3 and 7-11 weeks old, and were largely confined to Angus calves.

The belief that fluoridated water reduces caries incidence by half stems from years of fluoridation studies where the caries rates of people in various fluoridated and non-fluoridated communities were compared. By their nature, the water fluoridat...

NaCl reabsorption by the thick ascending limb of the loop of Henle (THAL) occurs via the apical Na-K-2Cl cotransporter, NKCC2. Overall, NKCC2 activity and NaCl reabsorption are regulated by the amount of NKCC2 at the apical surface, and also by ph...
