The authors gives a comparative schedule of characteristic ova features collected from 13 kinds of threadworms, parasites found in the digestive duet of sheep and illustrates it with drawings and photos. On base of faeces examination she detected ova belonging to Oesophagostomum columbianum Curtice, a parasite which was not quoted in the Polish fauna up to now

EFFECT OF TREATMENT ON GASTRO-INTESTINAL NEMATODES INFECTION OF HEIFERS AND THEIR WEIGHT GAINS IN SOUTHERN POLAND

The level of infection with gastro-intestinal nematodes in heifers of 3 farms (668 head) was studied by coproscopical methods and the efficacy of treatment was evaluated. Extensity of infection reached 80% and intensity (EPG) - 120. Comparative studies of weight gains of heifers treated and untreated revealed that the best results were obtained in heifers treated twice a year in May and August. The efficacy was estimated at 93% with respect to extensity of infection and at 97% for EPG. Mean final weight gains of the treated heifers were by 8,0-16,8 kg higher compared to those of untreated heifers. The mating time for treated heifers was about 30 days earlier than that for untreated ones

The gastro-intestinal nematodosis of heifers under large-scale management system

The levels of infection with gastro-intestinal nematodes were compared in heifers of various technological groups. The highest inddence and intensity (EPG) were found in the oldest age-group (2-year-old). Mean values of the highest infectionin seasonal dynamics occured in May and August.The infection of the Nilverm treated heifers, used for mating and of those used for breeding, was lower than that of the untreated ones.The average final body-weight gain of pregnant heifers after treatment was by 24.3 kg (4.6%) higher compared with that of the untreated heifers.The average final body-weight gain of heifers in production cycle after treatment was by 7.6 kg (1.6%) higher compared with that of the untreated heifers. The heifers after treatment were used for mating 18 days earlier than untreated ones

THE INFLUENCE OF DIFFERENT MANAGEMENT SYSTEMS ON THE INFECTION LEVEL OF SOME GASTROINTESTINAL PARASITES IN SHEEP IN SOUTHERN POLAND

On the basis of the fecal egg counts, larval cultures and necropsies the infection of coccidia, tapeworms and gastrointestinal nematodes in dams and lambs under extensive and intensive management systems were estimated. During 1994 and 1995 total of 1740 coproscopic analyses were done. It was state, that in extensive farms the prevalence and EPG of gastrointestinal nematodes was higher in comparison with intensive management system (38.2-86% and 13.9-71.9% and 105-355 EPG and 33-131 EPG respectively). Similarly prevalence of tapeworms 0-18.2% and 1.3-8.3% respectively. Prevalence and intensity of coccidia was lower in extensive farms (20-78,5% and 83-482 OPG) comparing with intensive management system (38.2-88% and 139-2846 OPG). Predominant nematode species in both management systems were those from genes Haemonchus, Teladorsagia, Trichostrongylus, Cooperia and Nematodirus. One species - Nematodirus battus was found new for Poland
