Shark Meal as a Protein Supplement in Dairy Calf Rations¹

Florida Agricultural Experiment Station, Gainesville, Florida

ABSTRACT

Shark meal was compared with roller process powdered skim milk as a protein supplement in simple rations fed to Jersey calves. Using the paired feeding technique, 6 pairs of females were fed 8 to 24 weeks of age on rations containing 14 per cent of protein.

The 6 calves fed the shark meal rations made an average gain of 118.4 pounds in body weight and 16.3 centimeters in height at withers. Their pair mates fed the powdered skim milk rations gained 117.1 pounds and increased 15.9 centimeters in height at withers. The difference in growth rate is not significant at the 5 per cent level. The average rate of growth was slightly below the normal reported for Jersey females.
