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 2 nd 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 5 th lactation (48,5 days) and minimal in the 4 th 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%). INTRODUCTION Investigations begins in the necessity of deep knowledge of morpho-productive traits which characterize biologic material Romanian Spotted bred and exploited into a private micro-farm (Family association). Also it was effected a study of possibilities to copro- parasitosis diagnosis in main digestive endoparasitosis in cattle which can influence some qualitative and quantitative index of milk production. MATERIAL AND METHODS Investigations regarding the main morpho-productive traits of biologic material from Romanian Spotted breed and the incidence, were effected in a family association in Cluj county, in March 2007, on 70 heads cattle livestock of Romanian Spotted breed and crossbreds, thus structured: 36 dairy cows, 10 pregnant heifer, 24 young stock 0 – 18 months. Breeding and exploitation technology of cows it’s done in bound system, on individual bed, and faeces removal is by hand. Young stock is bred separately, in collective boxes, free stalling. Milking is realized with milking machines in cans Alpha Laval, existing a collection and cooling tank of milk. Diary cows feeding is done with meals, succulents and concentrates in cold season, respectively green mass pasturing and concentrates in estival season. Data obtained, regarding production performances were processed statistically from U.A.R.Z. It were effected diagnosis copro-microscopic investigations of some digestive
