Levels Of Milk Glycosaminoglycans In Holstein Cows With Clinical And Subclinical Mastitis, Nicolas Caggiano, Elisa Crespi, Gonzalo Fiorini, Emilio De Simone

Turkish Journal of Veterinary & Animal Sciences

Mastitis is an inflammation of the mammary gland whose diagnosis is based on clinical criteria and the determination of inflammatory markers. The disease is mainly caused by bacteria causing intra-mammary infections. The etiological agent/s are detected by milk culture or by molecular biology approaches. However, these methodologies are unpractical for on-farm diagnosis, where rapid decisions must be made when infected animals are detected. For this reason, the levels of glycosaminoglycans (GAGs) in milk were evaluated as a tool for the diagnosis of mastitis. GAGs levels were determined by the dimethylmethylene blue assay (DMMB) method in milk from healthy animals and …

Turkish Journal of Veterinary & Animal Sciences

Two fat sources, soybean oil (SO) and refined poultry oil (RPO), and 4 emulsifiers (control, lysolecithin, lysophospholipid, and bile acids) were used in this experiment. Thirteen hundred and sixty (1360) birds (ROSS - 308) were divided into 8 groups having 5 replicates, 34 birds in each. Energy efficiency, feed conversion (FCR), and protein efficiency ratios were improved in birds receiving SO than RPO diets. Weight gain, FCR, feed intake, and dressing percentage were increased in broiler birds receiving bile acid than those given lyso-phospholipid and lysolecithin (p < 0.05). Cooking loss was greater (p < 0.05) in broiler birds given RPO than those fed SO. Birds receiving bile acid had greater (p < 0.05) water holding capacity of chest meat than other fat emulsifiers. Bile acids in broiler diet presented higher (p < 0.05) digestibility of crude protein and ether extract as compared to other treatments. Bile acid supplemented diets had a minimum (p < 0.05) cost of production per kg live weight than other fat emulsifiers. Therefore, the use of bile acids with RPO diets can increase nutrient digestibility, growth performance, meat quality, and economic efficiency in broiler production systems.

A Biological Perspective On Interpreting Interaction Effect, Serdar Genç, Mehmet Mendeş Jan 2022

A Biological Perspective On Interpreting Interaction Effect, Serdar Genç, Mehmet Mendeş

Turkish Journal of Veterinary & Animal Sciences

Factorial experiments are commonly employed in agricultural research as in other branches of applied sciences. In these experiments, inferences related to the interaction are essential. However, many researchers are still unable to analyze this type of experiment and interpret the results in the correct way. This is because researchers focus on interpreting the main effects although there is a significant interaction effect. Of course, meaningful main effects can exist even in the presence of an interaction, especially if interactions do not affect the main effects. Therefore, it is extremely important to understand thoroughly in which situations only the interaction effect(s), …
