the purpose of this research was to investigate the effectiveness of eclectic model based on acceptance and commitment therapy (act) and metacognitive therapy (mct) on symptoms in patient with pure generalized anxiety disorder. the research method was clinical experimentation with pre-posttest and control group. statistic community was all of the men and women patients that suffered from pure g...

background: cardiovascular system is a very importantorgan that plays a vital role in tissue function. in farm animals,the growth and high milk production depends on function ofcardiovascular system. objectives: cardiovascular health inhigh and low-yielding dairy cows was investigated. methods:fifty 4-year-old high- yielding holstein dairy cows and fifty 4-year-old low- yielding holstein dairy ...

Beef derived from Holstein steers is a significant source of the U.S. beef supply. The nation’s 9.1 million dairy cows in 2003 were 22% of the U.S. cow herd (NASS, 2005). Given the typical breed distribution of dairy cows, calving interval, full-term pregnancy rate, peri-natal calf death loss (NAHMS, 2002), gender distribution, dairy beef placement (80%) and survival to market (94%), it can be ...

This investigation was conducted to identify polymorphism of the leptin gene in Holstein cows, Mazandarani native cattle and buffaloes by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). The frequencies of A and B alleles were 0.4 and 0. 6 in Holstein cows, 0.56 and 0.44 in Mazandarani native cattle, 0.61 and 0.35 in buffaloes, respectively. The heterozygote genoty...

Complex vertebral malformation (CVM) is a recently described monogenic autosomal recessive hereditary defect of Holstein dairy cattle that causes premature birth, aborted fetuses and stillborn calves. Guanine is substituted by thymine (G>T) in the solute carrier family 35 member A3 gene (SLC35A3). A valine is changed to a phenylalanine at position 180 of uridine 5'-diphosphate-N-acetyl-glu...

Intake and annual performance of Limousin × Holstein-Friesian and Simmental × Holstein-Friesian beef suckler cows, and pre-weaning growth of their calves Beef cross dairy heifers remain a significant source of replacement breeding stock for the suckler herd in Ireland. Previous studies at this centre have compared Hereford × Friesian beef suckler dams with Charolais × Friesian and Limousin × Fr...

To analyze the resistance against Theileria sergenti infection in Holstein and Japanese Black cattle under field conditions, clinical, hematological and parasitological findings in these breeds of cattle that were grazed in the same pasture were examined during the grazing period. Holstein cattle showed a higher level of parasitemia than Japanese Black. With the progression of parasitemia, pack...

Charolais sires can be mated to Montbéliard or Holstein dairy cows to produce crossbred calves sold for meat production. Heritabilities and correlations between traits can differ when they are calculated within Charolais × Montbéliard or within Charolais × Holstein population. Moreover, the genetic correlation between the same trait measured on Charolais × Montbéliard and on Charolais × Holstei...
