The effects of maturity of maize at harvest, level of inclusion and potential interactions on the performance, carcass composition, meat quality and potential concentrate-sparing effect when offered to finishing beef cattle were studied. Two maize silages were ensiled that had dry matter (DM) concentrations of 217 and 304 g/kg and starch concentrations of 55 and 258 g/kg DM, respectively. Grass...

background: one of the factors that can improve self-concept and performance of staff is professional maturity. professional maturity can also solve the problems of self-concept. the purpose of this paper was to identify the relationship between the dimensions of self-concept and professional maturity.   materials and methods: this relative applicable study was performed on all the personnel (n...

the evaluation of gene bank germplasm collection for morpho-physiological traits is important in the breeding programs. although phenotypic variation was considered, it is likely that this phenotypic variation is largely genetic and therefore directly useable for breeders, especially for those traits with high heritability such as heading and maturity time, plant height, kernel number and weigh...

A major concern for those taking care of preterm infants is to ensure that nutritional intake meets requirements, thereby ensuring that poor nutrition is not rate limiting on outcome. However, establishment of an adequate intake is diYcult during early life in the sick infant. Dietary needs also vary, depending on maturity and nutritional and clinical status. Furthermore, measures of outcome ar...

BACKGROUND Sperm ion channel proteins (CatSpers) are essential for sperm hyperactivated motility, and then penetration through the zona pellucida. The CatSper class of proteins have well been characterized in the mouse and human. However, such data for pigs are not available. In the present study, we cloned the porcine CatSper 1-4 genes, analysed their spatial expression in various organs and t...
