Abstract

Three dietary treatments were compared over two years to determine the effects of dietary protein levels and feeding patterns on velvet production in red deer (Cervus elaphus). The LL group received a 13% protein diet whereas the HH group received a 19% protein diet. The LH group switched from the low to high protein diet at the time of antler casting. Significant relationships were found between velvet production and the girth and length of main beam (p<0.01), daily growth rate of velvet (p<0.01), body weight at cutting time (p<0.05 in 1998 and p<0.01 in 1999), date of casting (p<0.01), and body weight and velvet production of the previous year (p<0.05 in 1998 and p<0.01 in 1999). Different levels of protein in diets in this study did not show statistically significant different effects in general. The girth of velvet, summed for top, middle and bottom of the main beam, tended to be thickest in HH for two years and thinnest in LL for 1998 and in LH for 1999. The main beam tended to be longest in HH at 46.3cm in 1998 and 45.2cm in 1999 and shortest in LH at 39.9cm in 1998 and 41.5cm in 1999. Velvet fresh weight tended to be highest in HH at 2,600$\pm$1,000g in 1998 and 3,038$\pm$867g in 1999 and lowest in LH at 2,287$\pm$826g in 1998 and 2,739$\pm$1,079g in 1999. Daily growth rate of velvet antler tended to be greatest in HH (43$\pm$16g/day in 1998 and 51$\pm$14g/day in 1999) and least in LH (38$\pm$15g/day in 1998 and 45$\pm$18g/day in 1999).
