Body weight, haematocrit value, haemoglobin content and selected blood biochemical parameters in 5-month-old Polish longwool lambs, in relation to sex

The aim of the studies was to determine the influence of sex on the level of selected blood haematological and biochemical indices in 5-month-old Polish Longwool lambs. The studies pointed to higher levels of the Ht indices and Hb content (P≤0.01 ), activity of ALT and AST transaminase, Mg, Fe, total iron binding capability and total protein (P≤0.01), and a lower level of Cu (P≤0.01) in the blood serum of male lambs.
