MAIN MORPHO PHYSIOLOGIC INDEX STUDY AND INCIDENCE OF SOME DIGESTIVE ENDOPARASYTOSIS IN CATTLE

Abstract

Investigation done regarding the main morpho-productive traits and incidence of some digestive endoparasytosis on a 70 cattle livestock, of R.S breed and crossbred in an exploitation family association type, reveals aspects as: milk production, on total lactation, has an average value of 4583,97±185,23 kg, with maximal value in the 2nd lactation, of 5254,4±468,6 kg and minimal value of 3668,0±428,7 kg. Fat percentage with an average of 3,68±0,07, is superior to STAS value (3,5%). Mammary repose period of time is framed in normal limits (X 39,9 days), with maximal values in the 5th lactation (48,5 days) and minimal in the 4th one (34,7 days). Incidence of eimeria and trichostrongylidosis presents different values, function of age category. So, in eimeriosis the extent is maximal in dairy cows (30,0%) and minimal in young stock (16,6%), in trichostrongylidosis we have a maximal incidence in pregnant heifer (50,0%) and minimal in young stock (30,0%). Coprology elimination quantum of eimeria ovocyists presents maximal values in dairy cows (600 OPG) and minimal in young stock (350 OPG), and in trichostrongylidosis the maximal level of coprology eggs eliminations is in pregnant heifers (900 OPG) and minimal in young stock (450 OPG). In hepatic trematodosis the parasite extent is in fascioliasis with maximal values in pregnant heifers (75%) and minimal values in dairy cows (30%), and in dicrocoeliosis maximal values obtained are in young stock and dairy cows (50%) and minimal, in pregnant heifers (25%).
