The histopathological examination of 11 mesenteric lymph nodes from adult sheep infected with immature stages of Linguatula serrata revealed acute and chronic lesions with the presence of bacterial colonies and yeast cells. Bacteria were mainly present in acute, hemorrhagic, or necrotic lesions while yeast cells were seen mostly in the structure of chronic granulomas.
A quick and direct method based on reversed phase high performance liquid chromatography with fluorescence detector for measuring tocopherols (α , β + γ and δ) has been developed. Oils are diluted in methanol: hexane: tetrahydrofuran (neither previous extraction of tocopherols nor saponification procedure are required) and after being vortexed and centrifuged, an aliquot of the overlay was injected directly into an Alltima C 18 column. Acetonitrile and methanol (50: 50) mixture was used as a mobile phase with a flow rate of 1 mL min -1 . Quantification of tocopherols was performed by fluorescence detector at 290 nm excitation wavelength and 325 nm emission wavelength. Tocopherols were separated at 25°C in less than 10 min after injection. The method has good limit of detection (9 ng g -1 for α-tocopherol and 8 ng g -1 for β-, γ-and δ-tocopherols) and reproducibility (CV< 2.9 %). This method can be used to assess the influence of genetic modification of oil seeds on the distribution of tocopherols or the effect of tocopherols on the oxidative stability of edible plant oils.
It was examined the in luence of seasons and farming systems on hematological pro ile of rainbow trout (Oncorhynchus mykiss). In the classical growth system, the mean values of hematological indices showed large variations, depending on the season. In the recirculating growth system, hematological indices were relatively constant, regardless of the season.
Consumption of meat and meat products is an essential component in the human diet (Banu C. 2007). To assess the quality of meat products obtained from SC "Marele Alb" SRL Turda where carried out physical-chemical and microbiological analyses, effected periodically and on lots.
In order to increase the quantity and quality of milk production, animal fertility and natality, many dairy farmers grow specialized dairy breeds, including Red Holstein breed, or practice some crossbreeding with those breeds. The aim of this work was to determine the production potential of Red Holstein cows, and milk quality, in terms of somatic cell count and total germ number. The study was conducted on a herd of 20 Red Holstein cows from the S.C. Agro Laura farm, Sălaj County, which was analysed in terms of quantity and quality of milk produced in 2012-2014. The amount of milk was estimated based on daily production obtained from the total number of milked cows, while milk quality was established based on milk samples collected monthly and analysed by standard procedure in a specialised laboratory. In the analysis performed we found that daily milk production was on average about 22.4 kg/head, while somatic cell count and total number of germs were within the standard limits of 136-506 cells/ml x 10 3 , with an average of 258 cells/ml x 10 3 , and 24-279 germs/ml x 10 3 , with an average of 120.5 germs/ml x 10 3 . This research has confirmed the good potential for milk production of the studied cattle breed, with the productive performance over 10,000 kg milk, close to the real genetic potential of the breed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
