The objective of this study was to assess variance components and genetic parameters for fat and protein content in Tsigai sheep using multivariate animal models in which fat and protein content in individual months of lactation were treated as different traits, and univariate models in which fat and protein content were treated as repeated measures of the same traits. Test day measurements wer...

protein content and its effect on the quality of fresh pastas, obtained from dough preparedwith different formulas: semolina, wheat flour, gluten, wheat bran and soybean proteins, were evaluatedin this paper. tests were carried out in the laboratory using raw materials from the same batch nationalorigin. raw materials were mixed in an auxiliary kneading machine with a 500 g -capacity. the dough...

melamine is a potentially hazardous compound and one of the major concerns especially in dairy products and pet foods. in the present study a sensitive, simple and reliable method for extraction and determination of melamine in infant milk and coffee mate has been developed. this method consists of an initial extraction in buffer media prepared by formic acid and sodium formate, followed by pro...

Individual fish processing waste stream components can be used to make feed ingredients or other products. Waste stream components obtained from commercial fish processing plants included heads, viscera, frames, and skins from Alaska pollock (Theragra chalcogramma) and Pacijic cod (Gadus macrocephalus); and heads, and viscera from pink salmon (Oncorhynchus gorbuscha). The protein content of hea...

one concern about using transgenic plants is the genetic variation that occurred from theirs tissue culture and regeneration. molecular markers are an important element for efficient and effective determination of genetic variation. the present work was carried out to assess the genetic uniformity of transgenic cottons (bt and chitinase lines), using rapd, issr molecular markers and sds-page an...

This research aimed to determine the effects of different cover crops and application ofbio-fertilizer on dynamic of nitrogen in the soil and sweet maize yield. Also, we evaluated theeffect of fall–winter species (common vetch, field pea, winter oats, fodder kale) and a mixtureof vetch and field pea with oats used as cover crops, as such as dead organic mulch andtraditional variant, without cov...
