OBJECTIVES To evaluate short-term effects of publishing revised lower risk national drinking guidelines on related awareness and knowledge. To examine where drinkers heard about guidelines over the same period. DESIGN Trend analysis of the Alcohol Toolkit Study, a monthly repeat cross-sectional national survey. SETTING England, November 2015 to May 2016. PARTICIPANTS A total of 11 845 adu...

the aim of the present study was to estimate the genetic parameters and genetic trends of somatic cell score (scs) in the first 3 lactations of iranian holstein cows by random regression (rr) animal model by using restricted maximum likelihood (reml) method. the data set used in this analysis included observations of 340318 test-day records of 41526 cows in 288 herds; 89969 test-day of 11750 co...

objective: estimation of genetic parameters for kleiber ratio (kr) and genetic trends for pre-weaning weights of arabi sheep has not been previously conducted.methods: data and pedigree information were collected at the khuzestan ramin agricultural and natural resources university, animal science research station, located in southwest iran, from 2001 to 2008. (co)variance components and corresp...

data related to holstein dairy cattle from 1987 to 2004 were obtained from animal breeding center of iran to estimate the genetic and phenotypic trends. variance components and genetic parameters of the first lactation records were estimated using restricted maximum likelihood method and aireml algorithm through matvec program. animal breeding values were predicted through multiple-trait animal...

genetic trend for production traits were estimated in iranian holstein cattle using the first lactation data recorded by cattle breeding and dairy product improvement center of the state from 1991 to 2006. effect of some factors on genetic trend was investigated using data from 18 large herds. (co) variance components and genetic parameters were estimated, using five trait animal model and em-a...

this study was carried out to investigate the effect of selection on the reduction of fat-tail size in lori-bakhtiari lambs. the study lasted for five years at the development and breeding center of lori-bakhtiari sheep station. estimation of fat-tail weight, using external fat-tail dimensions was obtained from regression procedure at 6 month age. soft tissue depth at the point 12 cm from the m...

the objective of this research was to estimate the genetic parameters and trend of somatic cell count in holstein cows of iran using test day records. the phenotypic the used data consisted of were consisting of 407167 first lactation test day records the which were collected by the center of animal breeding and livestock production improvement center of iran during 2009 to 2013. somatic cell c...
