The two experimental treatments were: 1) chicks that reared under normal temperature (NT) and 2) chicks that reared under cold temperature (CT). The experiment was terminated at 42 day of chicken age. Feed intake was reduced significantly by ascites during the starter period. Weight gain of NT birds was higher than CT birds during the starter, grower, finisher and the whole period (P<0.05). Feed conversion ratio was greater for CT birds during the grower, finisher and the whole period (P<0.05). Total mortality was greater in CT birds than NT ones during the whole period (P<0.05). Cold-induced ascites increased the right ventricular, total ventricular and ventricular septum weights and right ventricular (RV)/total ...

One hundred and sixty day old chicks (Ross 308) in four treatment and 4 replicate each based on a completely randomized design were used. Immune organs relative weight such as spleen and bursa fabriciuse not affected by using of thyme extract at 21 and 42 days of experimental period but higher bronchitis antibody titer for the birds consumed 0.2 and 0.6% of thymuse vulgarise showed (P<0.05) as compared with those consumed the 0.4% thymuse vulgarise extract and control birds at 21 days of age. Moreover, consumption of thymuse vulgarise extract in water increased the bronchitis antibody titer as compared to the control birds in orthogonal comparsions. But there were no significant differences between the treatments for bronchitis antibody titer at 42 days of age and Newcastle antibody titer at 21...

One hundred and sixty mixed one-day-old broiler chicks (Ross 308) in four groups and 10 birds for each based on a completely randomized design were used. All the chickens were fed the similar starter (day 1-21 of age) and grower (day 22-42 of age) diets in pellet form, but received 0.0 (ZM), 0.2 (LM), 0.4 (MM) and 0.6% (HM) alcoholic extract of Mentha piperita in drinking water during the experimental period. At 21 and 42 days of age, two birds per pen were selected, weighed and killed by decapitation to obtain the immune organs relative weight such as spleen and bursa fabricius. Consequently blood samples were collected and blood serum was separated to measure of Newcastle and Bronchitis disease viruses antibody titers by using the elaisa reader. All experim...
The effect of dietary varying levels of crude protein on carcass traits and fleece characteristic... more The effect of dietary varying levels of crude protein on carcass traits and fleece characteristic of Markhoz (Iranian Angora) kid goats was studied. Fifty four male kids were used in a completely randomized design with 3×3 factorial experiment and given different diets for 98 d. The results showed that, the effects of dietary different levels of CP were statistically significant (P<0.05). The higher supply of dietary protein resulted in heavier (P < 0.05) slaughter BW, empty BW, hot carcass weight and higher (P < 0.03) dressing percentage than lower dietary nutrient concentrations. Increasing dietary protein increased (P<0.05) fiber length and fiber diameter but had little effect on greasy fiber weight, fiber strength and fiber efficiency. In conclusion, it could be said that dietary nutrients concentration has a main role in increasing mohair fiber and particularly meat production by Markhoz kid goats.

All the chickens were fed the similar starter (day 1–21 of age) and grower (day 22–42 of age) diets in pellet form, but received 0.0 (ZM), 0.2 (LM), 0.4 (MM) and 0.6% (HM) alcoholic extract of Mentha piperita in drinking water during the experimental period (day 1 to day 42 of age). Performance (feed intake, body weight gain and feed conversion ratio), hot carcass and proportional weights of thigh, wing and abdominal fat were not affected by mentha consumption. But breast proportional weight increased linearly as the mentha extract level increased. Positive and negative quadratic regression models were observed between mentha extract level with the liver colour index and liver proportional weight respectively. Mentha extract supplementation decreased plasma total cholesterol, triglyceride, LDL- C and VLDL- C quadrically. It was concluded that mentha extract consumption in drinking water can have beneficial effects on plasma lipoproteins and breast proportional weight. Moreover it decreased the synthesis of lipids in liver and consequently decreased the liver proportional weight and increased the liver colour index.

Up-to-date data about population status and induced threat on the Great Bustard is necessary to design a reaction plan and conservation measure. Therefore, this study was conducted to investigate the status of Great Bustard population in Mokryan region, NW Iran in January to December 2011. Based on the final reports, the Great Bustard habitats were destroyed in some parts of country except for Mokryan, in south of West Azerbaijan province. The sites around Boukan are the main refuge in Mokryan that Great Bustard breeds in its dry land and survive the wintering time there. The results of this study indicated that optimal habitats in NW (Mokryan) approached to desolation and their Great Bustard population linearly has decreased in comparison to past years; howe...

Twenty four Markhoz male goat kids (BW = 18.6 ± 0.7 kg) were assigned randomly to 1 of 4 treatments and were fed with different levels of DTP (10, 20 and 30% DTP) for 94 days. The first group was fed a basal diet without DTP and considered as control, while the other three groups fed the basal diet after substituting part of the diet with DTP at 10, 20 and 30%, respectively. There was no significant (P<0.05) difference between experimental groups in live body weight, weight gains and feed intake. Differences between digestibility of DM, OM and NDF were not significant, while there was significant difference (P<0.05) in the CP digestibility between experimental diets and the diet contained 20% DTP had the highest values compared to other treatments. The inclusion of DTP in Markhoz goats' diet was associated...

OBJECTIVE Examining the level of this cytokine along with other related factors can help to better understand the pathogenesis of this disease METHODS In this cross-sectional study, 48 patients with COVID-19 whose disease was confirmed by swap testing were evaluated. The demographic information of the individuals, the symptoms of the disease, and the ward in which they were admitted were recorded. Blood samples were taken from patients to test for interleukin-6 levels by ELC testing. Due to the lack of specific treatment protocols for patients and the use of supportive treatments based on meeting the nutritional needs for all patients, blood albumin levels and nutrition...

A total of 160 day-old broiler chicks (Ross 308) were assigned to 4 treatment groups with 4 replicate and 10 bird per each. All the chickens were fed a similar basal diet, but received different levels of 0.0% (ZT), 0.2% (LT), 0.4% (MT) and 0.6% (HT) alcoholic extract of Thyme vulgaris during a 42 period. LT recived birds had the highest FI between the treatments during the grower period and whole the experimental period. BWG of LT birds was higher as comperd to MT birds during whole the experimental period (P≤0.05). During the grower period, both the LT and HT birds had lower FCR as compared to ZT birds (P≤0.05). In orthognal contrasts, thyme extract supplementation in drinking water increased FI during starter period (P≤0.05) whereas decreased FCR during the starter, grower and whole the experimental periods (P≤0.05) compared to ZT b...

Fifty four male kids were used in a completely randomized design with 3×3 factorial experiment and given different diets for 98 d. The results showed that, the effects of dietary ME and CP level on body weight changes, average daily gain (ADG), dry matter intake (DMI) and feed conversion ratio (FCR) were statistically significant (P<0.05). The higher supply of dietary energy and protein resulted in heavier (P < 0.05) slaughter BW, empty BW, hot carcass weight and higher (P < 0.03) dressing percentage than lower dietary nutrient concentrations. Increasing dietary energy and protein increased (P<0.05) fiber length and fiber diameter but had little effect on greasy fiber weight, fiber strength and fiber efficiency.
