The main objective of the present study was to estimate genetic and phenotypic trends for body weight traits in Guilan province sheep. Traits included were birth weight (BW, n=14,549), 3-month weight (3MW, n=13,109) and 6-month weight (6MW, n=10,141). Data and pedigree information used in this study were collected during 1994 to 2011 by the Agricultural Organization of Guilan province in Iran. ...
Future progress in genetic improvement and the monitoring of genetic resources in beef cattle requires a detailed understanding of the population under selection. This study examines the gene flow in the UK beef population with an uncommon breeding structure involving interaction between the beef and dairy populations. British Cattle Movement Service records were used as the primary source of i...
a territorial isolation is a danger to the game population, causing deterioration called the inbreeding depression. the typical signs are anomalous body proportions, such as short lower jaw, shortened lifetime, weak physique and lower birth rate. this is caused by low number of game in the community. white colored deer is in the location of the czechrepublicbred in separation since 18th century...

background : the application of ventilation systems in industries and workplaces is with the aim of improving environmental conditions for employees. the lack of appropriate ventilation system components design and control methods result in the production of sound and vibration in most components. the purpose of this study was to determine the role of the pad isolator in controlling vibration a...
in the present study the allelic polymorphisms of gh, ghr and tgfβ3 genes and its association with egg production traits were investigated. blood samples randomly were collected from breeder hens of mazandaran native fowls breeding station and transported to the laboratory in cold chain condition. dna was extracted using modified salting out method and the desired loci were amplified by specifi...
AIM The objective of this research is to report parameters for breeding soundness evaluation, semen extension, and cryopreservation in Rusa timorensis. MATERIALS AND METHODS Seven healthy stags were chosen for semen collection using an electroejaculator. The collections were performed twice in a breeding season between February and June 2016. Samples were collected between 2 and 3 weeks inter...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
Background: Breeding soundness evaluation (BSE) is the primary assessment for determining reproductive potential of male animals. This method, however, cannot be used to evaluate semen frequently or to predict future semen quality. Computerized analysis of ultrasonographic images provides information on histophysiological changes in male reproductive organs.We hypothesized that: 1. semen parame...
