Öğe Akkaraman, I?vesi ve Bunların Alman Siyah Başlı ve Hampshire Down ile Melezlerinin (F_1_B_1) Yapağı Özellikleri(1998) Tekin, M. Emin; Gürken, Mehmet; Kadak, RamazanBu araştırma, Akkaraman, İvesi ve bunların Alman Siyah Başlı ve Hampshire Down etçi ırkları ile F_1 ve B_1 melezlerinin yapağı verim ve özelliklerini incelemek amacı ile yapılmıştır. Araştırmada, 1995-1996 yıllarında elde edilen toplam 622 kırkım kaydı kullanılmıştır. Yapağı verim ve özelliklerine, genotip, yaş, kırkım yılı, cinsiyet ve kırkım sonu vücut ağırlığının ve bunların etkileşimlerinin etkileri Genel Doğrusal Model (General Linear Model, GLM) ile analiz edilmiştir. Kirli gömlek ağırlığına incelenen tüm faktörlerin; lüle uzunluğuna cinsiyet dışındaki faktörlerin; elyaf çapına genotip, cinsiyet ve kırkım yılının; ondulasyon sayısınaa ise sadece genotipin, kemp ve medulla oranına kırkım yılı ve genotipin etkisi önemli bulunmuştur. Kirli gömlek ağırlığı, lüle uzunluğu, elyaf çapı, ondulasyon sayısı ve kempli-medullalı elyaf oranı, sırası ile, Akkaramanlarda 2.31 kg, 12.16 cm, 29.19 \mu , 5.44 adet ve %1.30; İvesi'lerde 3.02 kg, 14.99 cm, 32.36 \mu , 3.53 adet ve %2.37; Akkaraman melezlerinde (iki etçi ırkın F_1 ve G_1 leri) 2.90-3.15 kg, 10.11-12.90 cm, 27.23-28.64 \mu , 6.05-6.77 adet ve %0.43-0.87 arasında; İvesi melezlerinde 2.60-3.46 kg, 8.37-14.46 cm, 27.56-30.05 u, 5.50-7.67 adet ve %0.36-1.38 ve bütün özelliklerde genotipler arası fark önemli bulunmuştur. Kırkım sonu canlı ağırlığının kirli gömlek ağırlığı ile 0.43 (P0.001), lüle uzunluğu ile 0.09 (P0.05); kirli gömlek ağırlığının lüle uzunluğu ile 0.29 (P0.001); lüle uzunluğunun elyaf çapı, ondulasyon sayısı ve kemp oranı ile 0.28, -0.42 ve 0.25 (P0.001); elyaf çapının ondulasyon sayısı ve kemp oranı ile -0.27 ve 0.35 (P0.001); ondulasyon sayısının kemp oranı ile -0.22'lik (P0.001) korrelasyonları önemli, diğer korrelasyonlar önemsiz bulunmuştur. Sonuç olarak, İvesi F1 melezlerinin yapağı verim ve kalitesinin İvesi'den yüksek olduğu, Akkaraman melezlerinin ise, yapağı verimi dışında Akkaraman'lardan farklı olmadığı, Alman Siyah Baş ve Hampshire Down melezlerinin birbirine benzer olduğu, F_1 ve G_1 generasyonlarının Akkaraman melezlerinde benzer, İvesi melezlerinde farklı ( F_1 ler G_1 lerden yüksek) olduğu kanaatına varılmıştırÖğe Alman Siyah Başlı X Akkaraman ve Hampshire Down X Akkaraman Melezi (F1 ve G1) Erkek Kuzuların Besi Performansı ve Karkas Özellikleri(2000) Akmaz, Ali; Tekin, M.

Etki?leri?(Selçuk Üniversitesi, 1995 Nisan) Keçeci, Tufan; Kocabatmaz, Mehmet; Kadak, RamazanThis study was conducted to investigate the effect of ruminal infusion of acetic acid on the ruminal pH, volatile fatty acids (VFA) and protozoa in the sheep. Two fistulated sheep were infused through rumen fistula with 500 ml water (control) or acetic acid (0.62 gr/kg body weight) before feeding for 4 consecutive days. Samples of rumen contents were collected from each sheep before and 1 h after, infusion through the ruminal fistula. Acetic acid infusion has caused a significant drop in the ruminal pH. Furthermore, there was a reducing effect of acetic acid on number of ruminal protozoa. Especially, the Holotrich protozoa were the most susceptible, Whereas Entodinia were the least sensitive to the reducing effect of acetic acid. While the proportions of Holotrich species decreased, the proportions of Entodinium species were generally found to be increase after acetic acid supplementation into the rumen of sheep. Compared with the values of same parameters in the sheep given water, acetic acid proportions and total VFA levels were determined to be higher, but the proportions of propionic and butyric acids were found lower levels in the sheep given acetic acid.Öğe Electrocardiographic Studies in Brown Swiss Cows(Selçuk Üniversitesi, 1992 Ocak) Başoğlu, Abdullah; Turgut, Kürşat; Ok, Mahmut; Kadak, RamazanYaşları dört ile sekiz arasında değişen toplam 43 adet sağlıklı İsviçre Esmer ırkı sığırda elektrokardiyografik parametreler ölçüldü, hesaplandı ve analizleri yapıldı.

Emin; Aral, Faruk; Kadak, Ramazan; Çolak, Mehmet; Akın, A. İhsanBu araştırma, Konya şartlarında açıkta, seyyar kulübelerde buzağı büyütme imkanlarının araştırılması amacı ile yapılmıştır. Araştırma materyalini, Konya Hayvancılık Araştırma Enstitüsü'nde 1996 ve 1997 yıllarında yetiştirilen 35 baş erkek ve 38 baş dişi olmak üzere toplam 73 baş Esmer ırk buzağı oluşturmuştur (37 baş Deneme, 36 baş Kontrol). Veriler 18 ay süre ile alınmıştır. İstatistik analizlerde, araştırma grupları, mevsim ve cinsiyet faktörlerini içeren Genel Doğrusal Model (GLM) kullanılmıştır. Araştırmada deneme ve kontrol gruplarında sırasıyla, doğum ağırlığı 40.8 ve 38.1 kg (P0.01), sütten kesim (3. ay) ağırlığı 97.5 ve 102.6 kg, 6. ay ağırlığı 155.8 ve 159.3 kg, 0-6 ay arası günlük canlı ağırlık artışı 647.6 ve 667.3 g bulunmuştur. Aynı sıra ile, cidago yüksekliği, vücut uzunluğu, göğüs çevresi ve incik çevresi ölçüleri sırasıyla; doğumda 73.1 ve 71.9 cm, 68.1 ve 69.8 cm, 78.8 ve 77.4 cm, 11.7 ve 11.7 cm; 3. ayda 83.1 ve 82.3 cm, 79.7 ve 80.0 cm, 103.6 ve 102.5 cm, 13.2 ve 13.2 cm; 6. ayda 95.5 ve 94.3 cm, 95.4 ve 95.4 cm, 138.9 ve 134.6 cm, 14.8 ve 14.8 cm bulunmuştur. Yaşama gücü, aynı sıra ile, %100 ve %94.4 olmuş, araştırma boyunca deneme grubunda 30, kontrol grubunda ise 67 hastalık vakası görülmüştür. Günlük canlı ağırlık artışında cinsiyetin etkisi önemsiz iken, mevsimin etkisi önemli (P0.05) bulunmuş, bu değer en düşük (596.1 g) sonbahar, en yüksek (700.7 g) kış doğumlularda bulunmuştur. Vücut ölçülerinde cinsiyetin etkisi doğumda önemsiz iken, 2. ve 6. aylarda önemli bulunmuştur. Mevsimin etkisi de her üç ölçüm döneminde de bazı ölçülerde önemli, bazılarında önemsiz bulunmuştur. Sonuç olarak, gerek canlı ağırlık artışı, gerekse vücut ölçüleri yönünden araştırma ve deneme grubu arasında önemli bir fark bulunmadığı, buna karşılık deneme grubunda yaşama gücünün nispeten daha yüksek olduğu ve daha az hastalık vakası görüldüğü, literatüre göre de seyyar kulübelerin yatırım masraflarının daha ucuz olduğu da düşünüldüğünde, Konya şartlarında açıkta, seyyar kulübelerde buzağı büyütmenin mümkün ve daha avantajlı olduğu söylenebilir.Öğe Süt Sığırlarında Plazma Vi?tami?n A ve ß-Karotin Düzeyleri?ni?n Araştırılması(Selçuk Üniversitesi, 1989 Ocak) Nizamlıoğlu, Mehmet; Acet, Ahmet; Tiftik, Ali Muhtar; Traş, Bünyamin; Kadak, RamazanThe aim of this present study was to investigate the coversion of ß-carotene to vitamin A by measuring plasma vitamin A and ß-carotene in dairy cows. In this study, a total of 14 Brown-Swiss Cows, in 4-6 years old, supplied by Konya Animal Research Centre, were, used as materials. Animals were diveded into two equal groups. Group1; control group. Group 2; supplemented with ß-carotene (1 gr/day/each cow). Blood was sampled weekly from the animals during the experimental period of 5 weeks. ß-carotene and vitamin A levels in the blood samples were assayed by using HPLC. In group 2, plasma vitamin A and ß-carotene levels were increased statistically significant (P <0.01, P < 0.05). As a conclusion, it will be useful to supplement ß-carotene in dairy cows when the plasma ß-carotene and vitamin A are low.Öğe The wool characteristics of Turkish Merino, German Blackheaded Mutton Sheep, Hampshire Down, Lincoln Longwool, Corriedale and their F-1 and B-1 crossbreed sheeps(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1999) Tekin, Mehmet Emin; Kadak, Ramazan; Akmaz, Ali; Ergin, AliThis study was conducted to investigate the wool characteristics of Turkish Merino, German Blackheaded Mutton Sheep, Hampshire Down, Lincoln Longwool, Corriedale and their F-1 and B-1 crossbreed sheeps. A total of 2669 shearing records obtained from 1993 to 1996 were used in this study. The effects of genotype, age, shearing year, sex and post shearing body weight on greasy fleece weight and wool characteristics were examined wit least Squares method. The effects of all the examined factors on greasy fleece weight and staple length were significant, except sex on staple length. The effects of genotype and shearing year on fibre diamater were significant, and the effects of genotype, sex and shearing year on fibre twine were significant. The population averages of greasy fleece weight, staple length, fibre twine and fibre diamater were 3.29 kg, 9.81 cm, 8.38 units and 24.55 mu, respectively, for Merino and crossbreds. The least squares means of same characteristics for Turkish Merino were 3.29 kg, 7.90 cm, 10.24 units and 21.32 mu; and for all of crossbreed types 2.77-3.77 kg, 8.55-11.23 cm, 7.29-9.08 units and 23.90-25.72 mu respectively; and the difference between genotypes were statistically significant. The correlation between post shearing body weight and greasy fleece weight, staple length, fibre twine and fibre diamater were 0.31, 0.14, 0.12 and -0.10, respectively, in Turkish Merino crossbreeds; between greasy fleece weight and staple length, 0.31; between staple length and fibre twine -0.37; and between fibre diameter and staple length and fibre twine were 0.29 and -0.29, respectively. All these correlations were significant.

These animals were divided into there groups. Twelve mg of Zeranol were implanted subcutaneously to ear of the first and second groups lambs. Fourty days later, the same dose of Zeranol was reimplanted to the second group lambs. The remaining 15 lambs were served as nonimplanted controls. Five lambs belonging to each group were slaughtered at 80, 120 and 160 days after implantation. Before slaughtering the lambs body weight were measured. Then testes, epididymides, vesicular glands and bulbourethral glands were weighted. The testes weights and their ratio to the body weights in the Zeranol implanted groups slaughtered at the 80 th days were significantly lower than the control group. No differences were found in testicular of lambs slaughtered at the 120 th and 160 th days. On the other hand, any significant differences were not observed in the bulbourethral glands, vesicular glands and epididymal weights between the three groups.
