    Blood Plasma Progesterone Levels do not Correlate with Litter Size in the American Mink (Neovison vison)
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Seremak, Beata; Dworecka-Borczyk, Marta; Felska-Błaszczyk, Lidia; Lasota, Bogdan; Department of Biotechnology of Animal Reproduction and Environmental Hygiene, West Pomeranian University of Technology, Szczecin, Poland; Department of Biotechnology of Animal Reproduction and Environmental Hygiene, West Pomeranian University of Technology, Szczecin, Poland; Laboratory of Animal Anatomy Faculty of Biotechnology and Animal Breeding, West Pomeranian University of Technology, Szczecin, Poland; Department of Biotechnology of Animal Reproduction and Environmental Hygiene, West Pomeranian University of Technology, Szczecin, Poland
    The aim of the study was to test whether there is a relationship between the plasma concentration of progesterone in a given stage of pregnancy and the litter size at birth. The study was carried out on a mink farm located in western Poland. Blood samples for analyses were drawn from year-old White Hedlund (WH) females. Samples were collected from 30 females, first on 22 February, i.e. before the mating season, and on 12 April, from pregnant females, about 3 weeks before expected parturitions. Plasma progesterone levels revealed a high individual variability within the studied group of mink. No significant correlation was found between blood plasma progesterone in pregant females and the average litters size at birth.

    When present in the environment in large concentration, mercury can pose serious danger to human and animal health and life. Mercury poisoning in human organism can lead to, for example: central nervous system damage, immune system disorders, kidney damage, hair loss and death. Besides its impact on public health, mercury also affects animal production, with a variety of poisoning symptoms in farm and game animals, lower birthrates, reduced production qualities and deaths. Mercury is considered a global threat to the environment, due to its ability to accumulate in living organisms. In modern times the main risks of exposure to mercury for people and animals are: contaminated food products and water. For this reason, mercury levels in animal meat and organs are regulated by national and international legislation. The aim of this study was to establish possible hygine and toxicologic risks related to mercury accumulation in meat and organs of farm and game animals accuired in Poland. Results of several studies on mercury content in meat and liver of farm and game animals have shown that the species of animal. its age, environment and diet can affect mercury accumulation levels. The data collected in Poland during last 10 years in Poland indicates that mercury levels remained low, with sporadic incidents of allowed levels being exceeded.

    Nutritional Value of Poultry Meat Utilized in the Dogs Diet
    (Wydawnictwo Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Biel, Wioletta; Czerniawska-Piątkowska, Ewa; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin, Poland; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin, Poland
    Poultry meat is an important source of energy and nutrients, ensuring high quality of protein in the diet of dogs. The aim of the research was to determine the quality of broiler chicken meat. The experimental material of the paper were broiler chickens ROSS 308 reared in controlled environmental conditions up to 42 days of age. The content of basic ingredients and the amino acid profile were determined in breast and thigh muscles. Based on the research, it was found that the breast muscles contain more protein and less fat than the thigh muscles. The femoral muscles were characterized by a higher content of intramuscular fat, which influenced their higher energy value. Poultry meat has a high protein nutritional quality, is a good source of essential amino acids, which is beneficial in terms of nutrition.
