EFFECT OF THERMAL INDICES AND RELATIONSHIPS WITH MILK YIELD IN EXOTIC DAIRY COWS USING INVASIVE AND NON-INVASIVE MARKERS
Abstract A study was conducted to evaluate the effects of thermal indices and relationship with milk yield in dairy cows using invasive (glucose, total cholesterol, triiodothyronine (T3), thyroxine (T4), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and inorganic phosphate) and non-invasive (Rectal temperature (RT), respiration rate (RR), ear temperature (ET) and skin temperature (ST) markers in the Sahel Savannah of Nigeria. Fifteen (15) clinically healthy dairy cows of three breeds; ...
