Bu çalışma,
yüksek diyetli nitrat alımı ve inorganik kükürt ilavesinin Ankara keçilerindeki
tiroid hormonlarına etkisini belirlemek amacıyla yapıldı. Çalışmada, yaklaşık
14 aylık yaştaki 18 erkek Ankara keçisi 3 gruba bölündü: kontrol grup bazal
diyetle beslendi, nitrat grubu 1500 ppm nitrat 
ilave edilen bazal diyetle beslendi ve nitrat+kükürt grubu 1500 ppm
nitrat ve %1.8 sodyum sülfat ilave edilen bazal diyetle beslendi. Çalışmanın
45., 90., 135. ve 180. günlerinde serum örneklerinde tiroid uyarıcı hormon
(TSH), total ve serbest triiyodotironin (TT₃ veFT₃)
ve tetraiyodotironin (TT₄ ve FT₄) düzeyleri ölçüldü. 180.
günde, TT₄ hariç, serum TSH, total ve serbest T₃ ve serbest T₄
konsantrasyonları nitrat+kükürt grubunda 
kontrol ve nitrat grubundan daha yüksekti (P<0.01). Bu çalışma, Ankara
keçilerinin tiroid hormonları dikkate alındığında 1500 ppm nitrat içeren bir
beslemeyi tolere edebileceğini ve inorganik kükürdün doza bağlı olarak tiroid
hormonları üzerine yüksek nitratlı diyetin olumsuz etkilerini hafifletmek
için  doğal bir kaynak görevi
görebileceğini önermektedir.

Effects of Sulfur Supplementation on Thyroid Hormones in Angora Goats Fed With a High-Nitrate Diet

Öz

This
study was to aimed for determination the effect of high dietary nitrate intake and inorganic
sulphur supplementation on thyroids hormones in Angora goats. In this study, eighteen male Angora
goats aged 14 months were  divided into
three groups (n = 6):   control group fed with a basal diet, nitrate
group fed with a basal diet supplemented with 1500 ppm nitrate, and nitrate +
sulfur group fed with a basal diet supplemented with 1500 ppm nitrate and 1.8%
sodium sulfate. On days 45, 90, 135, and 180 of the study, the concentrations
of the thyroid-stimulating hormone (TSH), total and free triiodothyronine (TT₃
and FT₃),
and tetraiodothyronine (TT₄ and FT₄) were measured in the serum samples.
On day 180, except for TT₄, the serum TSH and total and free T₃
and free T₄ concentrations were higher (P<0.05) in the nitrate +
sulfur group than in the control and nitrate groups. This study suggested that Angora
goats could tolerate a feed containing 1500 ppm nitrate with respect to the
thyroid hormones, and inorganic sulfur might serve as a natural source for
alleviating the negative effects of the high-nitrate diet on the thyroid gland
in a dose-dependent manner.
