Pozycja Open Access Polymorphism in the GHRL Gene and Milk Production Traitsin Jersey Cattle(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2023) Śpiewak, Magdalena; Kowalewska, Inga; Department of Genetics, Faculty of Biotechnology and Animal Breeding, West Pomeranian University of Technology, Szczecin, Poland; Department of Genetics, Faculty of Biotechnology and Animal Breeding, West Pomeranian University of Technology, Szczecin, PolandThe aim of this study was to assess potential relationships between GHRL 4491A˃G genotypes and selected milk production traits, including milk yield, protein and fat content, and protein and fat yield. The study involved 180 Jersey cows. Genotypes of individual animals were determined using the ACRS and PCR-RFLP methods. The allele frequencies were as follows: A – 0.98 and G – 0.02. The conducted research revealed statistically significant relationships (P ≤ 0.05) between GHRL genotypes and milk protein content, and tendencies were observed regarding the association of genotypeswith analyzed milk production traits.Pozycja Open Access The Effect of Selected Factors on Rearing Performance of Charolais Calves(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2023) Pytlewski, Jarosław; Antkowiak, Ireneusz R.; Czerniawska-Piątkowska, Ewa; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences, Poznań, Poland; Department of Animal Breeding and Product Quality Assessment, Poznań University of Life Sciences, Poznań, Poland; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin, PolandThe aim of this study was to determine the effect of selected factors on rearing performance of Charolais calves to day 90 of life. The experimental material comprised 83 Charolais cows calving in the winter and spring seasons and calves they reared (84 head) to day 90 of life. All calves born by the experimental females were weighed at birth and then at days 30, 60 and 90 of life. Calves were also subjected to zoometric measurements. Their height at sacrum and width at hips were measured at days 10 and 30 of life. The increments for height at sacrum and width at hips between day 10 and 30 of life were calculated for the calves. Rearing indexes of the calves were assessed in terms of calf sex (heifer vs. bull calves), calving season (winter vs. spring), successive calving of the cow (1, 2, 3 and >3), parturition type (normal vs. dystocia), body condition of the cow after calving (good vs. poor). It was shown that rearing performance of Charolais calves to day 90 of life was significantly affected by their sex, calving season, parturition type and body condition of the dam during calving. The most advantageous results for the assessed rearing parameters of Charolais calves to day 90 of life were recorded for male animals born in the winter season coming from normal births and produced by dams in good body condition during parturition.Pozycja Open Access Arthrospira - Nutritional Value, Health-promoting Properties and Possible Use as an Additive in Dog Nutrition. A Review(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2023) Kazimierska, Katarzyna; Kępińska-Pacelik, Jagoda; Biel, Wioletta; West Pomeranian University of Technology in Szczecin, Department of Monogastric Animal Sciences, Szczecin, Poland; West Pomeranian University of Technology in Szczecin, Department of Monogastric Animal Sciences, Szczecin, Poland; West Pomeranian University of Technology in Szczecin, Department of Monogastric Animal Sciences, Szczecin, PolandArthrospira (Arthrospira platensis, trade name spirulina) is commonly called “green meat” due to its high protein content (up to about 80% of dry matter). It is used in many countries as an additive in human and animal nutrition because of its high nutritional value. Arthrospira protein is of high quality due to the optimal composition of exogenous amino acids. Additionally, Arthrospira is a good source of fatty acids (including GLA, EPA, and DHA). It is used in formulas for complete and complementary pet foods. It can be a valuable source of complete protein for dogs. Its addition can significantly delay the process of lipid oxidation and reduce the number of undesirable microorganisms in the product. The pro-health properties of Arthrospira have been demonstrated in numerous scientific studies, including its effects on hypercholesterolemia, hyperglycemia, cardiovascular diseases, anemia, inflammatory diseases, cancer, and viral infections. The aim of this study was to characterize the nutritional values, health-promoting properties and the possibility of using Arthrospira as an additive in dog nutrition, based on a review of scientific literature.Pozycja Open Access Bladder Stones in a Nine Years Old Female Dog - Case Report(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2023) Jundziłł-Bogusiewicz, Paulina; Gruszczyńska, Joanna; Department of Animal Genetics and Conservation, Institute of Animal Sciences, Warsaw University of Life Sciences; Department of Animal Genetics and Conservation, Institute of Animal Sciences, Warsaw University of Life SciencesA nine years old female dog, crossbreed, spayed admitted to a veterinary clinic with a urinary tract problem. Symptoms have been grown slowly over six months. The dog was behaved normally at home, showing no pain. In the clinic the dog had ultrasonography of the abdominal cavity, the bladder wall was thickened, no other shading structures were found. It was deciding to do a diagnostic laparotomy. As a result of surgery, 4 stones were removed from the bladder. Oval stones with blunt edges, reached about 2 cm in diameter. Often non-specific symptoms may go unnoticed for a long time by the owner, and when the dog get to the veterinary clinic we can only chirurgic remove the stones. Especially, if urolithiasis is sterile urolithiasis and fills the entire bladder.
