Öğe Farklı Di?kalsi?yumfosfat Kaynaklarının Yumurta Tavuklarında Veri?m ve Kabuk Kali?tesi? Üzeri?ne Etki?si?(Selçuk Üniversitesi, 1994) Coşkun, Behiç; Azman, M. AliThis study was conducted to investigate four different Dicalciumphosphate's (DCP) produced in Turkey and two different imported DCP's and their effects on egg production and egg shell quality of two different strain laying hens. In order to investigate the effects of P sources on egg productivity and the quality of egg shell, 480 white and 480 brown laying hence were used. The experiment took 180 days to finish and feed consumption, egg yield, egg weight, feed conversion, shell thickness, shell weight, proportion of egg shell, and abnormal eggs were determined and evaluated Daily feed consumption was found 130.4 g as the highest level in (-) control group showing the significant differences from other groups (P < 0.05) and the dif ferences between the groups with additional P were found as non significant (P > 0.05) Related to egg yield and egg weight, the groups did not show significant differences (P > 0.05) . The lowest and the highest feed conversion value were found as 3.38 and 2.88 the (-) control and imported DCP II, respectively. Specific gravity (SG), which is used to determine the quality of egg shell, have not been affected by rations (P> 0.05). The best SG value was obtained as 1.086 in the (-) control group. The values of SG for the other ration groups were found 1.084 in the imported DCP's and 1.082, 1.084, 1.084 and 1.084 in the domestic DCP. The ratio of shell weight / egg weight is an other criteria to determine the quality of egg shell. These proportions were calculated 9.11 and 9.14 for the imported DCP's, 8.87. 9.04, 9.07 and 9.05 for the domestic DCP's, respectively The differences between the rations were not significant (P>0.05). As a result, the effects of different P sources on egg yield and egg shell quality were not significantÖğe Live Performance and Carcass Yields of Broilers in Different Intermittent Lighting Schedules(1996) Işcan, K. M.; Inal, Ş.; Dere, S.; Azman, M. Ali; Ünsaldi, T.The purpose of the present study was to measure performance and carcass yield from broilers maintained on different photoschedules and to compare electricity savings. Day-old 430 broiler chicks from an Avian × Peterson strain cross were used as research materials. There were four lighting treatment (LT) groups. All groups were kept under 231:1D from to 7 days. Four pens were randomly assigned to each of four light treatment groups: 1) 1L:1D, 2) 1L:2D, 3) 1L:3D, and 4) 23L:1D from 8 to 48 days. It was found that there were statistically significant differences for body weights (BW) between different lighting treatment groups at 42 days (P<.05), but that there were no differences with respect to BW between LT groups at 49 days. Feed efficiency values of groups 1, 2, 3, and 4 were estimated at 2.003, 1.987, 1.972, and 2.080, respectively. There were no statistically significant differences among treatments for mortality rates at 49 days of age. But mortality rates of the third and fourth groups were numerically bigger than those of the first and second groups. Mortality rates of the third and fourth groups were estimated greater than standard mortality rate values. The incidence of leg problems was influenced by lighting treatments. There were significant differences with respect to the weights of different parts of the carcasses (P<.01) and no differences for the percentages of carcass parts except in breast percentage between LT groups (P<.05). The carcass weights of first and second groups were found to be heavier than those of the other groups (P<.05). The amounts of electricity used by research groups 1, 2, 3, and 4 during the 49-day rearing period were determined to be 16.3, 12.2, 10.2, and 27.5 kW/h respectively. It has been conluded that continuous lighting treatment in broiler rearing has had no benefit in broiler performance.Öğe Mikrobiyel Inokulant ile Hazırlanan Yonca Silajının Merinos Kuzularda Canlı Ağırlık Değişimi ve Bazı Besin Maddelerinin Sindirilebilirliği Üzerine Etkileri(2001) Kurtoğlu, Varol; Şeker, Erdoğan; Çoşkun, Behiç; Gürkan, Mehmet; Azman, M. Ali; Balevi, TahirBu araştırma; mikrobiyel inokulant ile hazırlanan yonca silajmın (2. biçim) Merinos kuzularda canlı ağırlık değişimi, kuru madde tüketimi ve bazı besin maddelerinin sind'rilebilirliği üzerine etkilerinin incelenmesi amacıyla yapılmıştır. Araştırmada biri katkısız (kontrol), diğeri inokulant katkılı olmak üzere iki farklı siloda yaklaşık 25'er ton yonca silajı hazırlanmıştır. Katkılı silaja IxlO5 colony forming units (cfu)/g/yem düzeyinde Lactobacillus plantarum ve Streptococcus faecium 'dan oluşan bakteri kültürü (Pioneer 1174) ilave edilmiştir. Silajlar 4 ay kapalı tutulmuştur. Araştırmada 16 adet erkek ve dişi Merinos kuzu iki gruba ayrılarak denemeye alınmıştır. Kontrol grubundaki hayvanlara kontrol silajı (katkısız silaj); deneme grubundaki hayvanlara ise inokulant ilave edilmiş silaj verilmiştir. Araştırma 42 gün sürdürülmüştür. İnokulant ilavesi canlı ağırlık değişimi üzerine etkili olmamıştır (P0.05). Silaj kuru maddesi tüketimi araştırmanın 1-7 günlük döneminde inokulantlı ; grupta daha düşük (P0.05) bulunurken, diğer dönemlerde gruplar arasında bir farklılık gözlenmemiştir, inokulant ilavesi HY sindirilebilirliğini artırmış (P0.05), KM, OM, HP ve N-suz ÖM'nin sindirilebilirliğini önemli düzeyde etkilememiştir (P0.05).Öğe Süt I?nekleri?nde Veri?m Performansı, Rumen Parametreleri? ve Si?ndi?ri?lebi?li?rli?k Üzeri?ne Zeoli?ti?n Etki?si?(Selçuk Üniversitesi, 1999) Umucalılar, H. Derya; Azman, M. Ali; Arat, Emin; Akın, A. İhsanThis study was carried out to determine the effects of zeolite (Cki - n * ut / 1000) in dairy cattle ration and 16 lactating Brown Swiss cattle were used. Six percent of zeolite was added to the concentrate diet in test group. In the research was determined dry matter intake, milk production performance, rumen pH, total volatile fatty acids (TVFA). ammonia nitrogen (N*H_{3} - N) crude protein and crude fiber digestibility. In the experiment, dry matter intake, milk production were found in control and test groups 14.97 and 14,17 kg/day, 15.66 and 16.37kg / d * ay respectively and there was no significant difference between groups (P > 0.05) In control and test groups, average milk dry matter fat, protein were determined 12.26 and 12.14%, 3.94 and 3.76%, 3.34 and 3.29% (P > 0.05) At the end of the research, the addition of zeolite did not influence mean ruminal pH, ammonia nitrogen and total VFA concentration which were de- tected 6.88 and 6.88, 183.6 and 217.2 mmol/l, 139.2 and 129.2 mmol/l, respectively (P > 0.05) Estimates of crude protein and fiber digestibilities in test group (67.63%, 69.95%) were lower than control (72.70%, 77 39%) and crude fiber digestibility was found significant difference between groups (P < 0.05).Öğe Tri?ti?kale'ni?n (Triticale) Etli?k Pi?li?ç Rasyonlarında Kullanılabi?li?rli?ği?(Selçuk Üniversitesi, 1999) Coşkun, Behiç; Azman, M. Ali; Tekik, Havva; Arat, EminThis study was conducted to determine the effects of added 15-30% triticale in broiler chick diets and 20- 40% triticale in broiler diets on the growth performance of broiler. A total number of 390, day old (Avian) commercial hybrid broiler chicks were used in the study. Material was divided into 3 groups, each consisting of 5 replicates. The rations of control groups contained maize (0 triticale), triticale was used at rate of 15% and 20% (Group II) and 30% and 40% (Group III) in broiler chick diets and in broiler diets respectively. The study lasted for 42 days. Live weights averaged were found as 1814.5 (control), 1865.5 and 1866.3 g respectively. The differences were not significant (P > 0.05) Feed conversion rate were found as 1.96, 1.92 and 2.01 kg feed/ kg weight gains respectively (P> overline 0 * 0.05 ) . In conclusion, the finding of the study indicate that, the addition of 40% triticale in broiler diets does not have any ne- gative effects on the growth performance.
