Kidney and Marrow Fat as Indicators of White-Tailed Deer Condition

摘要: Comparisons of kidney fat indices and content femur marrow from 34 female whitetailed deer (Odocoileus virginianus) showed that is not a reliable indicator physical condition during mobilization fat. A method involving the complementary use two measurements suggested as means assessing over its entire range. This paper shows relationship to in white-tailed presents for condition. Riney (1955) studied various methods evaluating red (Cervus elaphus) New Zealand concluded weight expressed percentage valid index total body range was applied 66 collected Manitoba December, 1962, through April, 1963. The thus obtained decreased regularly winter until second week March when poorest had low 8. But next month only 1 15 an below 8 although their general appearance indicated several were poorer than any those previously. Since Harris (1945) Cheatum (1949) found last reserve be mobilized deer, I determine whether or further deterioration escaped detection by method. MATERIALS AND METHODS Kidney weights using described each animal calculated both kidneys order minimize variation. central 2 inches 397 cent water.

From standpoint, roots crowns rate considerably lower corn, but, at least season, they provide important source succulent browse.
