Öğe Comparison of immunogenicities of 3 different inactivated Newcastle vaccines (Manisa, Solvay ve Intervet) using in Turkey(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1999) Erganis, O; Ok, U; Coskun, B; Inal, F; Tifik, AMA total of 1134 laying hens (Hysex-Brown hibrid), 3 different groups bearing 378 laying hens at each group was used, in this study done to compare immunological effects of 3 different (Solvay, Intervet and Manisa) inactivated Newcastle vaccines with mineral oil adjuvant. Same vaccination program and rations were applied to chickens during the study. Inactivated Newcastle vaccines were used according to the prospectuse by subcutaneously at 17 th weeks before laying period. Blood samples were taken from 24 hens per group, by intracardiac punction, at 3 th weeks, 5 th weeks, 9 th weeks, 13 th weeks, 17 th weeks, 22 nd weeks, 27 th weeks, 32 nd weeks, 37 th weeks, 45 th weeks and 52 nd weeks after vaccination. All sera were tested by micro hemaglutinasyon-inhibition (mHI) test Antibody titers were recorded as log2 and statical analysis was calculated by varians analysis. No significant differences were found in antibody titers among the vaccines for first nine months period (until 32 nd weeks). In the last measurements (at 37 th and 45 th weeks), higher antibody titers were obtained in Manisa group. This vaccine (Manisa) found at international quality must to combine with other vaccines (such as IB, Gumboro, EDS 76, E. coli, Salmonella, ext.,) for widespread using at poultry flocks in Turkey.Öğe Determination of Protein Ruminal Degradabilities of Some Protein Sources(ECOLE NATIONALE VETERINAIRE TOULOUSE, 2003) Umucalilar, HD; Coskun, B; Gülşen, Nurettin; Polat, ES; İnal, FatmaIn this experiment, some of the protein sources such as meat-bone meal (MBM), fish meal (FM), soybean meal (SBM), cotton seed meal (CSM) and sun flower meal (SFM) samples were incubated in rumen for varying periods by using Nylon-bag technique and have been monitored for the Dry Matter Degradation (DMD), Crude Protein Degradation (CPD) and Effective Rumen Degradability of Protein (ERDP). The ERDP values of MBM was 50.26 %, FM 38.12 %, SBM 61.38 %, CSM 59.79 % and SFM 75.74 % in 5 % outflow rate/hour. There was a considerable variation in dry matter and protein degradation within and between feedstuffs.Öğe Effect of chromium and magnesium supplementation in broiler diets on body weight and some blood parameters(INDIAN COUNC AGRICULTURAL RES, 1999) Kalaycioglu, L; Coskun, B; Kurtoglu, F; Kurtoglu, VThe objective of the present study was to define: the effect of supplementation of 20 mg/kg chromium (Cr) and 600 mg/kg magnesium (Mg), including two protein levels on Peterson x Avian chicks used in a 2 x 2 x 2 factorial design. The experiment lasted 51 days. Three different diets were fed between the days of 1-22, 21-35, and 35-51. Live weights and feed intake values were determined weekly At the end of the experiment blood samples were drawn by cardiac puncture. Mg and albumin levels in serum were determined by using spectrophotometer and commercial test kits. In general, there were no statistically significant effects of Cr and/or Mg supplementation in broiler diets. But in low protein groups the supplementation of the minerals increased the growth performance parameters. High protein level diets unexpectedly reduced live weight gain and feed intake but feed conversion rates in high protein groups were better than the low protein. groups. High level of protein increased serum albumin but decreased Mg levels. Mg supplementation increased serum Mg levels but not serum albumin levels while Cr supplementation did not cause any effect on levels of both parameters.Öğe Effect of probiotic supplementation on laying hen diets on yield performance and serum and egg yolk cholesterol(TAYLOR & FRANCIS LTD, 2004) Kurtoglu, V; Kurtoglu, F; Seker, E; Coskun, B; Balevi, T; Polat, ESThe effects of dietary supplementation of a commercial probiotic (BioPlus 2B) on daily feed consumption, egg yield, egg weight, specific gravity, body weight, feed conversion ratio, serum and egg yolk cholesterol, and serum trigylceride in layer hens were investigated. In 12 replicates, 480 27-week-old Brown-Nick layers were fed with diets containing 0, 250, 500 or 750 mg kg(-1) probiotic for 90 days. When compared with the controls, supplementation of 250, 500 and 750 mg kg(-1) probiotic increased egg production, but decreased the damaged egg ratio (p<0.05), egg yolk cholesterol and serum cholesterol (p<0.001) levels. In addition, serum triglyceride levels were reduced by using 500 and 750 mg kg(-1) probiotic supplementation (p<0.001). Feed conversion ratios were positively affected by supplementation of 250 and 500 mg kg(-1) probiotic compared with controls (p<0.05). There was no statistically significant difference between the control and all treatment groups on feed consumption, egg weight, specific gravity, body weight, and egg yolk weight.Öğe Effects of dietary copper on production and egg cholesterol content in laying hens(TAYLOR & FRANCIS LTD, 2004) Balevi, T; Coskun, B1. This experiment was carried out to determine the effects of diets supplemented with different amounts of copper on egg production, food intake, food conversion ratio, egg weight, damaged egg ratio, specific gravity, mortality and cholesterol concentration in yolk. The experiment lasted 90 d and 400 Hisex-Brown hens, aged 27 weeks at the start of the study, were used. 2. There were no statistically significant effects of supplementary copper on egg production, food intake or food conversion efficiency. 3. There were no statistically significant differences between the groups in terms of damaged eggs, egg weight, specific gravity and live weight. 4. At the end of the experiment, the lowest yolk cholesterol concentrations were obtained in the 150 kg/kg copper group and the greatest concentrations were in the control group. 5. Consequently, the use of supplementary copper to provide 150 kg/kg in poultry diets was concluded to decrease yolk cholesterol concentrations without any effect on production performance.Öğe The effects of withdrawal of vitamin and trace mineral supplements from layer diets on egg yield and trace mineral composition(CARFAX PUBLISHING, 2001) Inal, F; Coskun, B; Gulsen, N; Kurtoglu, V1. This study was conducted as three trials. 2. In the first trial, zinc, manganese, copper and iron concentrations were determined in dietary raw materials collected from various regions of Turkey. 3. In the second trial, 200 Hisex Brown laying hens, 30 weeks of age, were divided into two groups. The first group served as controls and were fed on a standard commercial layer diet. The second group were fed on a commercial layer diet that was not supplemented with trace minerals and vitamins. Egg production, egg weight, specific gravity, food consumption and food efficiency of the birds in each group were determined. In the unsupplemented group, egg production (0.75 vs 0.83) and food intake (114 vs 122 g) were lower than the those of the control group (P<0.05). Food efficiency was 2.42 (kg food/ kg gain) in the group consuming the unsupplemented diet and 2.36 in the controls. 4. In the third trial, as in Trial 2, Hisex Brown laying hens, 62 weeks of age were used. In the unsupplemented group, the mean egg weight was significantly lower than that of controls (68.0 vs 69.6 g) (P<0.01). 5. At the end of the second and third trials, egg samples collected from experimental groups were hard boiled in water. The levels of zinc, manganese, copper and iron in the egg yolk were determined. The zinc level of the egg yolk from the control group of second trial was higher (23.5 mg/kg) than those of the unsupplemented group (13.6 mg/kg).Öğe The nutritive value of Prangos ferulacea(WILEY, 2004) Coskun, B; Gulsen, N; Umucalilar, HDThis study was conducted to determine the chemical composition and nutritive value of Prangos ferulacea, a plant found in the Mediterranean and Middle-east regions, where it is used as animal fodder. Samples of mature plants were collected from S.E. Turkey. Metabolizable energy (ME) values were estimated from in vitro gas production measurements and from chemical composition. ME concentrations of the whole plant, leaves and stems were estimated to be 12.2, 11.9 and 12.7 MJ kg(-1) dry matter (DM) respectively, which compares favourably with high-quality forages commonly used in ruminant feeding. The DM degradability of the whole plant, leaves and stems increased up until 48 h of in situ incubation, 866, 915 and 784 g kg(-1) DM respectively, but changed little between 48 and 72 h. In vitro DM and organic matter digestibility of the whole plant, leaves and stems were 0.769 and 0.806, 0.773 and 0.790, and 0.740 and 0.840 respectively. The results show that P. ferulacea may be regarded as a high-energy forage, but further research is needed on its intake characteristics and the levels of animal performance that can be achieved from its inclusion in the diet.Öğe Prediction of nutritive value of a native forage, Prangos uechritzii, using of in situ and in vitro measurements(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2004) Gulsen, N; Coskun, B; Umucalilar, HD; Dural, HThis study was carried out to determine the chemical composition, in situ dry matter (DM) degradability, in vitro digestibilities and metabolizable energy (ME) contents of Prangos uechtritzii at different stages of maturity (prebud, mid-flower and late flower) naturally grown in some and regions of Turkey. The proportion of leaf at mid- and late-flower decreased compared to prebud stage. Stage of maturity affected DM and crude protein contents of the P. uechtritzii and fractions. In the whole-plant, NDF and ADF concentrations increased with plant maturity as a result of increased stem ratio. The effective degradability of dry matter, in vitro dry matter digestibility, in vitro organic matter digestibility, and ME did not change greatly by stage of maturity. Compared to ordinary forages used in ruminant feeding, the forage nutritive value of P. uechtritzii was equal to or better. (C) 2003 Elsevier Science Ltd. All rights reserved.
