    The activity of calves depends mainly on the way they are housed and not on their age. Because compromised welfare early in life may affect the profitability of future production, calves need to be fed colostrum after birth because their digestive tract is not physiologically active. Calves nurse their dams 7 times per day on average (for up to 70 minutes in total). Weaned calves are generally fed twice per day. Calves have the strongest sucking need between 4 and 5 weeks of age. Several-day-old calves that are housed in separate pens and artificially fed, spend around one-fifth of the day foraging or eating. Cattle have well-developed sense organs. The animals use their senses for foraging, spatial orientation, and social contacts. Cattle normally walk, and trot when frightened. Young calves often indulge in galloping, kicking with hind legs. During disease, the behaviour of calves considerably differs from normal. They respond differently to the environment, their appetite decreases, with changes in thirst, and sometimes in external appearance. Inadequate welfare levels lead to abnormal forms of behaviour, which are reflected in problems adapting to the environment (Kokocińska and Kaleta 2016).

    The evaluation of efficacy of Valbazen (Pflizer) in the treatment of gastro-intestinal tract parasite invasions in beef cattle of West Pomerania
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Juszczak, Marta; Uchwał, Paulina; Stępkowska, Paulina; Tomza-Marciniak, Agnieszka; Department of Biotechnology of Animal Reproduction and Environmental Hygiene West Pomeranian University of Technology, Szczecin; Department of Biotechnology of Animal Reproduction and Environmental Hygiene West Pomeranian University of Technology, Szczecin; Department of Biotechnology of Animal Reproduction and Environmental Hygiene West Pomeranian University of Technology, Szczecin; Department of Biotechnology of Animal Reproduction and Environmental Hygiene West Pomeranian University of Technology, Szczecin
    The aim of the study was to evaluate the extensity and intensity of gastro-intestinal parasitic infections in Limousine beef cattle in West Pomerania, Poland, and to assess the efficacy of Valbazen (Pfizer Inc., USA) in a treatment of cattle parasitic infections. The extensity of parasite infections in the examined cattle before the study was 100%. The study has shown the presence of gastro-intestinal nematodes, Eimeria sp. protozoa and Moniezia sp. tapeworms. The extensity of infection of gastro-intestinal nematodes and Moniezia sp. tapeworms was 97.8%, whereas in Eimeria sp. – 86.7%. The efficacy of Valbazen was checked on 21. day after the specimen application. The results of our study indicate a high efficacy of deworming procedure with Valbazen by Pfizer. The study has confirmed that the problem of presence of digestive tract parasites in beef cattle is still live. This in turn indicates the need of undertaking the screening studies in beef herds.
