To determine the effect of hen age and storage condition on egg quality, fresh eggs were sampled from two commercial
flocks of White Leghorn hens at 28 and 68 weeks of age. Half of sampled eggs from each flock were stored at 6°C and the
other half was stored at room temperature. Fifteen eggs were randomly sampled from each treatment following collection and
at 5-day intervals to 30 days of storage. Measurements were made of egg and egg component weight (W) and percentage (P),
yolk: albumen ratio, yolk and albumen dry matter albumen quality and height and yolk index. Egg, albumen and shell W,
yolk P and yolk: albumen ratio were significantly higher for 68 wk but albumen and shell P were higher than 28 wk. Increase
in temperature and storage time decreased egg and albumen W and albumen P, increased yolk and shell P and yolk: albumen
ratio significantly. Albumen DM was lower for 68 wk, lower temperature and shorter storage time. However hen age had no
effect on yolk DM, higher temperature and longer storage time decreased it. Albumen height and HU were significantly
lower for 68 wk, higher temperature and longer storage time. Hen age did not affected albumen pH but it was affected by
temperature and storage time. Yolk height and yolk index were higher for 28 wk age, lower temperature and lower for longer
storage time. Overall results showed that however longer storage time decreased egg quality, still it was acceptable.

In this study, the effects of different levels of garlic on performance and humoral immunity of broiler chicks were
investigated. Three hundred eighty four broiler chicks (Arian) from day one were divided into two groups of male and
female. Animals received four treatments diet including: 0.0% (control), 0.1% garlic Powder, 0.1% garlic tablet and 0.5%
garlic tablet from day 3 to 42 of age. A factorial design of 2 * 4 was applied for two sex and four treatment diets with four
replicates and 12 experimental units. Anti-SRBC titer for direct hem-agglutination assay and for the anti-Newcastle titer the
inhibitory hem-agglutination was used. At 42 days, chicks were slaughtered in order to weigh the bursa-fabricious (RF) and
spleen. The results of anti-SRBC titer, anti- Newcastle and weight of BF and spleen did not differ significantly when
compared to control group. However, feed intake, body weight and growth rate in 0.1 garlic powder in comparison with
garlic tablet showed an increasing trend. The results of immunity tests indicated that the levels of garlic used in this study had
insignificant effects on humeral immune parameters (p>0.05).

An experiment was conducted to investigate the effects of different levels of rapeseed meal and diet formulation based on
total and digestible amino acid (AA) using 192 day old Ross 308 male broiler chicks. Experiment was carried out using a
complete block design with 4*2 factorial arrangements. The factors included different levels of rapeseed meal (0, 10, 20 and
30%) and two method of AA formulation (based on total or digestible AA requirement). Four replicates of 6 chicks were fed
dietary treatments from 11 to 49 d of age during two period of grower (11-28 d of age) and finisher (28-49 d of age). Feed
intake and weight gain of each experimental unit was measured at 28 and 49 d of age and then feed conversion ratio was
calculated. At 28 and 49 d of age, blood sample were taken from wing vein of 2 birds per replicate and then T3 and T4
concentration of the sample were measured. Results show that different levels of rapeseed meal had no significant effect on
feed intake. Diets containing 20 or 30 % rapeseed meal had highest and lowest weight gain, respectively, during the grower
and finisher period. Method of formulation of AA requirements had significant effect on weight gain so that chicks fed diets
formulated on the basis of digestible AA had significantly higher weight gain. Feed conversion ratios were affected by both
different levels of rapeseed meal and method of diet formulation. Feed conversion ratios were increased by 30 % rapeseed
meal, whereas 20% rapeseed meal significantly lowered it. Formulation of diets on the basis of digestible AA also decreased
feed conversion ratios. Results obtained in our study suggest the inclusion of 20% rapeseed meal and diet formulation based
on digestible AA when rapeseed meal are used in the broilers diets.

Probiotics are used to control or maintain a constant state of intestinal bacteria. When the bacterial populations are altered by
stress or antibiotic therapy, animal health and performance may decline. This experiment was designed to study the effects of
feeding a Probiotic (Saccharomyces cerevisiae CNCM I-1079) on growth and health of neonatal Holstein calves. Forty –five
neonatal Holstein calves were selected from one dairy farm of Mashhad suburb. After birth, calves were randomly assigned
to three groups. Calves in group I (control group) received no probiotic. Calves in group II (experiment I group) were given
probiotic at 1gr/day with colostrum and then with milk during the first 2 weeks of life. Calves in group III (experiment II
group) were given probiotic at 1gr/day with colostrum and then with milk during the first 3 weeks of life. At the third week,
milk was replaced with milk replacer. The body weight and skeletal growth (Heart girth, body length and weithers height)
were measured at birth and repeated every week until 5 weeks of age. Blood samples were collected via jugular vein puncture
at the time ok weighing and analyzed for hematological indices, plasma total protein concentration and fibrinogen
concentration. Fecal scores (fluidity) were monitored and evaluated. All calves were monitored for health status and probable
health problems daily. Data were analyzed by using ANOVA, Kruskal-Walis and Chi-square procedure with SPSS 13. There
was not significant differences between groups for hematological indices, plasma total protein concentration and plasma
fibrinogen concentration, skeletal growth averege daily gain, the incidence of neonatal diarrhea and the days of the treatment;
however, fecal scores at third weeks of age between groups I (1/8±0/26) and III (1/07 ±0/07) was significantly different.

Eighteen female, neonatal Brown Swiss calves (39.5±1.2Kg) were randomly divided into three treatment groups to
investigate the effect of physical processing of diet on weaning age and some blood metabolites. Treatments were included:
mash starter (M), pelleted starter (P) and heterogen of mixture moisturized, rolled barley and corn. (H). Diets were
formulated to be isonitrogenous. There were no significant differences in weight gain, total intake of starter and feed
efficiency. Weaning age and total intake of milk dry matter were higher in calves received treatment (M) than other
treatments. Crud protein and organic matter digestibility were lower in treatment (M) than others, but there was no significant
difference between treatment (P) and (H). Treatments had no effect on blood glucose content, but BUN concentrations was
higher in treatment (M) than other treatments. Result of this experiment showed that feed pelleting and grain processing can
reduce weaning age and milk intake in calves but, had no effect on feed intake and gain weight until end of weaning age.

Four ahomasal cathetered multiparous lactating Sannen goats with mean milk production of 1.6 ± 0.64 kg and 139 ± 4 days in
milk were allocated to 4 treatments in a latin square design. The goats were fed a basal diet containing 40% alfalfa hay and
60% concentrate. The basal diet was supplemented by infusion of 1) water, 2) cottonseed oil (48 g/d), 3) glucose (100 g/d)
and 4) mixture of cottonseed oil and glucose (24 and 50/d) as experimental treatments. The experiment had 2 periods
including adaptation (14 days) and Collection (7days) periods. Infusion of cottonseed oil or glucose had no significant effect
on intake or digestibilies of DM, OM, CP, NDF and ADF, of the basal diet. There were no significant differences between
total protein, casein, NPN and whey content of milk samples. Infusion of cottonseed oil or mixture of glucose and cottonseed
oil increased milk fat percentage. It was concluded that supplying more energy as oil or glucose in abomasums in mid
lactation had no effect on productive performance of dairy goats, although infusion of cottonseed oil increased milk fat
percentage. Plasml cholestral and triglyceride levels increased by infusion of cottonseed oil, but plasma glucose and BUN
remained constant.

tannin on its digestibility and gas production, four experiments were carried out. In the first experiment, nutrient composition,
phenolic and tannin components of the Ohadi, Kaleghuchi and White varieties of pistachio by-product from dehulling
process were measured. Pistachio epicarp (hull) was the main part of this by-product. The Ohadi cultivar contained 9, 14, 8.7,
25.5 and 20.4% of ash, CP, EE, NDF and ADF, and 8.6 and 4.1% phenolic components and tannin, respectively. The
Kaleghuchi had lower CP than Ohadi and White varieties. The White variety had the lowest tannin level among them. In the
second experiment the ruminal disappearance of pistachio by-product constituents including hull, peduncle, leaf, mesocarp
and kernel until 24 h incubation were 0.77, 0.60, 0.66, 0.22 and 0.92 g/g, respectively; also the amount of soluble fraction of
these constituents were determined 0.52, 0.37, 0.36, 0.05 and 0.77 g/g, respectively. The third trial was consisted of

In a 3×3 Latin square design, 9 ok and multipaous lactating Holstein cows averaging 76 ± 12 days in milk and 580±48 kg of
body weight were assigned to three dietary treatments in 3 periods of 21 days. Dietary treatments were 1) the control diet
(without dried or ensiled tomato pulp), 2) diet with 8% dried tomato pulp (DM basis) and 3) diet with 8% ensiled tomato pulp
silage (DM basis). Tomato pulp either dried or ensiled was substituted with whole barley silage and cotton seed meal. Dry
matter intake, milk composition, blood metabolites and nutrient digestibility were not affected significantly by the treatments.
Milk production was increased significantly in response to tomato pomace substitution and reached to 41.36 and 41.16 kg/d
for the diets containing dried and ensiled tomato pulp respectively in comparison with the control diet (treatment). Total
chewing and rumination times did not differ between the treatments. Ruminal pH of cows fed diet containing ensiled tomato
pulp was significantly (P≤0.05) lower than the control diet. No seed was germinated in germination test possibly due to the
application of high temperature during paste production process. It was concluded that inclusion of 8-10% tomato pulp in dry
or ensiled forms in the dairy diets could reduced the cost of feed without any adverse effect on the cow's performances

The aim of current study was to determine the effects of vitamin C on bone mineral density (in terms of osteoporosis),
eggshell quality and investigation of correlation between these factors in laying hens reared under normal condition. One
hundred and ninety two 24 - weeks - old laying hens diet was supplemented with 4 levels of vitamin C (0, 250, 500 and 750
mg/kg diet). The experimental design was completely randomized (CRD). Egg production, metatarsus bone mineral density
(BMD) index and correlation coefficient between BMD index and some eggshell characteristics were determined. Egg
weight, egg mass, hen-day egg production and eggshell quality (shell thickness, shell weight and shell percentage) were not
influenced by vitamin C (p>0.05). The BMD index of metatarsus also did not change by vitamin C utilization at 38-weeksold
(p>0.05). No significant correlation was found between BMD index and shell characteristics (p>0.05). However, positive
correlation was observed between BMD index and egg weight also between BMD index and hen-day egg production

This study was done on 4 and 5 years old Great sturgeon cultured in brackish water ponds in Bafgh salt water fisheries
research station during one year. We examined somatic growth indices and effects of different diets on blood parameters and
total length and weight. Diet with constant protein (%40) and different energy levels (400,425,450,475 cal/100g) were fed to
74 pieces of Great sturgeons in 8 circle cement ponds. Biometry, as well as blood analysis were done every season. The assay
were done for glucose was measured with Auto analyzer, calcium and magnesium with spectrophotometer and sodium and
potassium with film photometer, Hormone levels (cortisol, testosterone, progesterone and esteradiol) were measured by
Radio Immunoassay (RIA) in Yazd central laboratory. Total length and weight were not affected by sex, but they were
affected significantly with season (p>0.05). The length and weight indices were also affected significantly by diet. Along
with increasing energy content, these indices were improved. Among analyzed blood parameters, just magnesium had
significant reverse correlation with total length and weight. Also, testosterone had direct correlation with total weight and
progesterone had reverse correlation with total length significantly. Growth indices had overlapped in both sexes (a little
more in male). On the other hand, Growth rate was similar in both sexes, but somatic growth indices were slightly improved
along with increasing age in males.
