    Association of Polymorphism of Choosen Genes with Production Traits in Dairy Cattle
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Czerniawska-Piątkowska, Ewa; Jadwiżak, Weronika; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin, Poland; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin, Poland
    Polymorphisms of DGAT1, ABCG2, SCD1 and PPARGC1A genes significantly affect the milk, fat and protein yield and chemical composition of milk. Depending on the type of polymorphism, they increase or decrease the milk, fat and protein yield as well as fat and protein content in milk. Based on the research carried out by numerous authors, it can be concluded that genotyping animals for polymorphism of selected genes and using this information in breeding programs for selection supported by markers, which will allow the development of populations with the most desirable production characteristics is right.

    Causes for Culling and Reproductive System Disorders in Jersey Cows in the Reproductive Period
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Pytlewski, Jarosław; Antkowiak, Ireneusz R.; Stanisławski, Daniel; Czerniawska-Piątkowska, Ewa; Rolińska, Karolina; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences, Poland; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences, Poland; Computer Lab, Poznań University of Life Sciences, Poznań, Poland; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin, Poland; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences, Poland
    The aim of this study was to analyse culling causes and determine reproductive health disorders in Jersey cows in the reproduction period in a herd from the Wielkopolska region. Analyses were conducted on 331 Jersey cows. The material for analyses was collected for the years 2010–2015 from the performance records of dairy cows, the AfiFarm herd management programme and veterinary inspection records. Source data concerned causes of cow culling and reproductive system disorders found in the reproduction period (i.e. from calving to successful fertilisation). Culling causes were divided based on the criterion applied by the Polish Federation of Cattle Breeders and Dairy Farmers. In this study the shares of culling causes were determined and the frequency of individual reproductive system disorders in the reproduction period were calculated in terms of the division into primiparous and multiparous cows. Sterility and reproductive system disorders were the most frequent culling causes in Jersey cows. In turn, endometritis was the most frequent reproductive disorder in cows of this breed in the reproduction period. No statistically significant relationship was found between the age group of cows (primiparous vs. multiparous) and the frequency of specific reproductive system disorders. The incidence rate of reproductive system disorders in Jersey cows in the reproduction period may most probably be reduced at a continuous improvement of environmental factors affecting these animals.

    The Milk Yield of Ukrainian Holstein Is Related to the Immunobiological Parameters of Blood of Calves
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Milostiviy, Roman; Antonenko, Petro; Kostyuk, Volodymyr; Vasilenko, Tatyana; Czerniawska-Piątkowska, Ewa; Dnepropetrovsk State University of Agriculture and Economics, Dnipro, Ukraine 1National University of Life and Environmental Sciences of Ukraine, Kyiv, Ukraine; Dnepropetrovsk State University of Agriculture and Economics, Dnipro, Ukraine 1National University of Life and Environmental Sciences of Ukraine, Kyiv, Ukraine; Dnepropetrovsk State University of Agriculture and Economics, Dnipro, Ukraine 1National University of Life and Environmental Sciences of Ukraine, Kyiv, Ukraine; Dnepropetrovsk State University of Agriculture and Economics, Dnipro, Ukraine 1National University of Life and Environmental Sciences of Ukraine, Kyiv, Ukraine; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin, Poland
    Decrease in productive longevity of dairy cows in conditions of industrial dairy complexes causes another problem, which is connected with the timely replenishment of the herd with calves for replacement. Therefore, the cultivation of heifers has very great impact. Much attention is focused on early prediction of the future calves productivity for obtaining highly productive cows. At the same time, the growth rates and development in ontogenesis are studied very often, but blood values are rarely evaluated. In the literature available to us, there is little information about the relationship between calves' humoral and cellular immunity values with the future productivity of the cow. These indicators are traditionally used to characterize the immunobiological reactivity of an organism and the calves' health, and there is practically no information on their relationship to the productive longevity of a dairy cow. This is partly due to the difficulties associated with the duration of the research, since the cow must complete its productive life. A positive and reliable relationship is established between the immunobiological characteristics of calves' blood and their lifelong milk yield when they become a cow. The greatest correlation was noted between the milk productivity's indicators and bactericidal activity of blood serum (r = 0.63–0.69, P < 0.05). The relationship between cellular factors of body defense (phagocytic activity of neutrophils) and the immunoglobulins content of classes G and M with signs of milk productivity was less dense. It was, respectively, r = 0.31–0.41 and r = 0.58–0.63 (P < 0.05). This makes it possible to conclude that the studies conducted in this direction are promising, and assessing calves' immune status for predicting the yield of cow milk. The results obtained by us require further confirmation in a more significant number of animals.

    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.
