showed that there were no significant differences in weight gain, feed intake and feed conversion ratio among

triticale, and corn gluten meal was formulated according to Quick Chick (2006) to be adequate in all nutrients
except for Thr. Incremental levels of supplemental Thr were added to the basal diet generating six experimental
treatments in a range from 0.46 to 0.81% digestible Thr. Birds were randomized across 48 floor pens (4
replicates and 12 birds in each replicate) in a completely randomized design and each pen was fed one of the six
amino acid levels from 15 to 28d of age. Body weight gain, feed intake, feed conversion ratio, and digestible Thr

levels of digestible Thr, and interaction effects between Thr and strain were significant for all performance traits
except for body weight gain. Strain did not affect the feed conversion ratio and feed efficiency was the same in
two strains. Digestible Thr requirements were estimated using broken-line linear and broken-line quadratic

in the north of Iran, the records from first lactation of 11398 collected from 1989 to 2006 were used. Records
were collected from 290 herds. Productive traits were 305 day-2x adjusted milk and fat yield and reproductive
traits were age at first calving, calving interval and dry days. Genetic parameters were estimated by univariate
and bivariate animal model using ASREML software. Estimated heritabilities for 305 day-2x milk, fat, age at
first calving, calving interval and dry days gathered from univariate analysis were 0.27 (±0.02), 0.19 (±0.02), 0.1
(± 0.02), 0.03 (±0.01) and 0.1 (±0.02) respectively. Genetic correlation between milk and fat yield was 0.82.
Genetic correlations of milk and fat production with age at first calving were -0.2 and -0.23 and with calving
interval were 0.31 and 0.40, respectively. Genetic trends for milk and fat yield were 2.8 (±0.4) and 0.05 (±0.01)
kg/year and for age at calving, calving interval and dry days were -0.28 (±0.01), 0.02 (±0.002) and -0.03

(days/year), 0.37 (days/year) and -0.36 (days/year). Based on unfavorable genetic correlations between
productive and reproductive traits, using a selection index including both of these traits is necessary for Holstein

two paternal lines A and B of a commercial broiler line were used. Line A were selected several generations for
low feed conversion rate and line B were selected several generation for high body weight. Body weight was
measured at 1, 4, 7, 10, 14, 17, 21, 28, 35, 42, 49 and 54 days of age and the growth curve were fitted by
Gompertz model. Moreover, feed conversion rate were evaluated just for 20% of birds within 23 and 54 day of
age. At the end of experiment, all birds were slaughtered and some carcass traits like breast weight, liver and
abdominal fat were assayed. The results of current study showed that mature index and the age at inflection point
in male birds of line B were higher than that in line A. Female broilers in line B showed higher hatch weight,
mature index and age at the inflection point than that in line A. The hatch weight, mature index and age at the
inflection point were similar between male and female birds in both paterntal lines. Liver weight, abdominal fat
and feed conversion rate among male birds in paterntal lines were no significant, but the difference in breast
weights in male broilers was significant. Breast weight, Liver weight and abdominal fat in female broilers in line
B were significant and higher than female broilers line A but food conversion rate was no significant. Liver
weight and abdominal fat were significant between males and females in parental line but, only breast weight
between male and female in line B was significant. The growth rate of birds in line B during 17 to 35 day of age
was higher than that in line A. Moreover the growth rate in male birds during 17 to 54 day of age was higher

microsatellite markers associated with Inhibin gene in Sanjabi sheep. For this purpose, blood samples were taken
randomly from 100 Sanjabi sheep (78 females and 22 males) at Mehregan Breeding Station at Kermanshah.
Modified salting out method was employed for extracting DNA. Subsequently, Polymerase Chain Reaction
(PCR) was carried out with specific primers pairs for amplification of microsatellite marker sites. The PCR
products were electrophoreses on acryl-amid gel. For detecting genotypes within the population, silver staining
method was used. Genetic analyses on genotypic data were carried out using POPGEN 1.32 and Cervus 2.0
softwares. Results showed, three alleles (C: 0.42, B: 0.28, A: 0.29), and 2 genotypes respectively, (AB: 0.32,
