Effects of Increasing Zinc Supplementation in Drinking Water on Growth and Thyroid Gland Function and Histology in Broiler Chicks
(M H Schaper Gmbh Co Kg, 2002) Dönmez, HH; Karsli, MA; Meral, I; Dönmez, N; Simsek, N
The aim of the study was to examine the effects of increasing zinc supplementation on growth, feed efficiency and thyroid function and histology in broiler chicks. Sixty new born male broiler chicks were randomly allotted into one of four treatment groups and fed for 60 d. Zinc (Zn) was added into drinking water at the levels of 0, 125, 500, and 1000 mg Zn/L. Body weight gain were significantly higher and feed efficiency were significantly lower in chicks supplemented with 125 mg Zn/L compared with chicks supplemented with 500 or 1000 mg Zn/L at the end of the experiment. Serum Zn concentration linearly increased with the increasing level of Zn intake. Serum triiodothyronine and thyroxine levels and the diameters of follicles of thyroid gland were significantly reduced with high levels (500 and 1000 mg Zn/L) of Zn intake at the end of the experiment. It was concluded that chick receiving 1000 mg Zn/L as ZnSO4 . 7H(2)O in drinking water showed signs of Zn toxicity.

On Lacunary Invariant Sequence Spaces Defined by a Sequence of Modulus Functions
(Elsevier Science inc, 2004) Karakaya, V; Simsek, N
The purpose of the paper is to introduce and study some sequence spaces which are defined by combining the concepts of lacunary convergence, invariant mean and the sequence of modulus functions. We also examine some topological properties of these spaces. (C) 2003 Elsevier Inc. All rights reserved.
