An experiment on Lohmann male broilers was conducted to evaluate the effect of different energy and protein levels on broiler performance and plasma concentrations of growth hormone (GH), thyroxine (T4), and triiodothyronine (T3). 600 day-old broilers were fed on either 2800(low-energy) or 3200(high-energy) Kcal ME/Kg diets with different protein levels during three periods of starter, grower a...

In this research, White spot syndrome virus (WSSV) with 105.4LD50.mL-1 inactivated with gamma irradiation at a dose rate of 14-15 kGy.sec-1 was used as a vaccine. Three hundred and sixty shrimp of Litopenaeus vannamei, medium body weight (MBW) 1.0±0.17g), were prepared and experimentally exposed. They were distributed among four groups, inclusing vaccinated-virus exposed (T1), vaccinated-nonvir...

The present study was designed to investigate the effects of VêO® premium and vitamin C (Vit. C) supplementation on lipid profile before during pregnancy in local Iraqi ewes heat stress. conducted a private field Fallujah city, west Iraq, period from 6/8/2019 8/2/2020. Twenty were divided randomly into four equal groups (5 for each group) first group (T1) given (4 g/ ewe/ day), second (T2) (2 t...

Broiler chickens were reared in batteries and fed diets designed to determine the effects of either ascorbic acid, aspirin (acetylsalicylic acid), lysine, or thiouracil on thyroid weight and serum thyroid hormone concentrations. Thyroxine (T4) and 3,5,5'-triiodothyronine (T3) concentrations in serum were determined by radioimmunoassay. Neither ascorbic acid nor lysine affected T3 or T4 concentr...

While 3, 3', 5'-triiodothyronine (reverse T3, rT3) has been detected both in human serum and in thyroglobulin, no quantitative assessment of its metabolic clearance rate (MCR), production rate (PR), or secretion by the thyroid is yet available. This study examines this information in euthyroid subjects and evaluates it in light of similar information about two other iodothyronines in the thyroi...

samples was significantly higher than the level (41±2 ng per 100 ml) in 27 normal adult sera; the corresponding mean serum T4 of 12.7±0.8 ug per 100 ml in cord blood also was significantly higher than that (8.6±41.9 big per 100 ml) in 108 normal adults. By contrast, the mean serum T3 concentration in 15 cord blood samples, 24±3 ng per 100 ml, was significantly, lower than the value of 126±43.2 ...
