    Effects of Boron Supplementation on Performance and Some Serum Biochemical Parameters in Laying Hens
    (Ecole Nationale Veterinaire Toulouse, 2002) Kurtoğlu, Vural; Kurtoğlu, Firuze; Coşkun, Behiç; Şeker, Esra; Balevi, Tahir; Çetinoğlu, I. S.
    In this study, the effects of dietary boron (0,50, 100, 150, 200 and 250 parts per million; ppm) on performance such as feed consumption, feed conversion ratio, egg production, body weight, egg weight, specific gravity, damaged egg ratio, and some biochemical characters (Ca, P and Mg) in 40 week old laying hens for 120 days were investigated. Boron provided significant improvements on serum Ca levels and damaged egg ratio. There was no significant difference between the controls and the boron supplemented groups in the feed consumption, feed conversion ratio, egg production, body weight, egg weight and specific gravity.

    Effects of Processed White Lupin Seed (Lupinus Albus L.) on Growth Performance of Japanese Quail
    (Ecole Nationale Veterinaire Toulouse, 2002) Arslan, Cavit; Şeker, Esra
    This study was carried out to determine the effects of differently processed white lupin seeds on growth performance in Japanese quail. Three hundred and sixty quail chicks were randomly distributed among four treatments using fifteen birds per pen and six pen replicates per treatment. Lupin seeds were processed to the Turkish Traditional Method (TTM) and extrusion (E) to eliminate alkaloids. Ours results indicate that TTM was more effective in elimination of lupin alkaloids than E. The diet of control (C) group did not include lupin. The other groups were fed with diets containing 15 % raw (R), TTM processed and E lupin. The study lasted for 6 weeks, first 3 weeks as starter period, last 3 weeks as growing period. At the end of the experimental period in the C, R, TTM and E white lupin groups live weight were found to be 166.79, 160.99, 166.53 and 161.58 g, average daily gain; 3.81, 3.67, 3.85 and 3.68 g, average feed intake; 14.87, 15.17, 15.17 and 14.04 g/day, average feed efficiency 3.87, 4.00, 3.92 and 3.71 respectively. It is concluded that R, TTM-processed and E lupins fed up to the 15 % level in quail ration had no negative effect on the growth performance of the animals.
