The objective of the work was to establish the relationships between the level of colostral immunity and degree of invasion caused by Cryptosporidia in calves. The studies were done on 155 calvse, 5—10 days old in 38 cowsheds and farms situated in one voivodeship. One of the cowsheds realizing the program of calves colostral feeding served as a standard. The Pfeiffer test was used to evaluate consumption of colostrum of a high content of antibodies. It was assumed that one dilution of 14% sodium sulfite corresponds to 15 g of immunoglobulins/L. The presence of Cryptosporidia in feces was examined by the method of Heine. It was found that extensiveness of Cryptosporidial invasion decreased significantly in calves fed an appropriate amount of a high quality colostrum. Increased also a negative relationship between the intensity of parasitic invasion and a good colostral feeding.
