Öğe Broyler Rasyonlarına Deği?şi?k Mi?ktarlarda Katılan Bi?oti?ni?n Besi? Performansı ve Karaci?ger Yağlanmasına Etki?si?(Selçuk Üniversitesi, 1988 Ocak) Tuncer, Şakir Doğan; Aştı, Reşat; Coşkun, Behiç; Şeker, Erdoğan; Demirci, ÜlkerThis study was carried out to investigate the effect of different amounts of biotin (0, 50, 100 and 150 ug/kg) added to the broilers' ration on growth performance and fatty liver syndrome. In this study, 1000 day-old Hybro chicks were used. They were distributed into 4 groups, each group containing 250 chicks and the experiment was ended at the 49th day. Mean final weight values in the groups were 1841.13; 1871.78; 1822.88 and 1848.39 g respectively. There were no significant differences among the live weights of the groups (P > 0.05). But the highest final weight was found in the group fed 50 µg/kg biotin. Total feed consumption for all groups were 4.295; 4.326; 4.378 and 4.294 kg respectively. There was no large variation among the groups related to feed consumption. Feed convertion were found to be 2.340; 2.312; 2.405 and 2.324 kg, respectively, during the experiment. According to these results, experimental group I (50 µg/kg biotin) consumed less feed for 1 kg weight gain than the others. At the end of the experiment, in macroscopic investigation, livers of the groups given 0 and 50 ug/kg biotin were seen pale in colour and fatty. In microscopic investigation of the livers in the same groups, severe lipid infiltrations were seen in the cytoplasma of paranchymal cells. The livers of second (100 ug/kg biotin) and third (150 ug/kg biotin) groups were macroscopically normal. Any lipid infiltration in the paranchymal cells were not observed. 50 pg/kg biotin improves the growth performance but the same level was not effective in preventing fatty liver syndrome. As a result, the use of the amount of 100 µg/kg biotin would be recommended in preventing the formation of fatty liver syndrome in broiler feeding.Öğe Broylerlerde Yağlı Karaci?ğer Sendromu Üzeri?nde Hi?stoloji?k ve Bi?yoki?myasal Çalışmalar(Selçuk Üniversitesi, 1987 Ocak) Aştı, Reşat; Tuncer, Şakir Doğan; Coşkun, Behiç; Başpınar, Nuri; Çelik, İlhami; Kalaycıoğlu, LeylaThis study was carried out to investigate the correlation between the fatty liver syndrome and some blood values in broilers fed with rations containing corn, sunflower oil and animal fat. Totally 150 day-old Arbro - 7 female chicks were used in the experiment. There were three groups each containing 50 chicks. The experiment lasted in 56 days. At the end of the experiment, a severe case of fatty livers was observed in the group fed with corn based ration. The highest SGOT (P<0.05) and FFA values were found in this group. In the other two groups fed differently with ration containing sunflower oil and the animal fat, the lesser amount of lipid infiltrations were observed. The total serum cholesterol levels in the group fed with animal fat were higher than the other groups (P<0.01). As a result, it can be deduced that the determination of SGOT values as well as the histological investigation would be helpfull in the diagnosis of subclinical fatty liver syndrome.Öğe The effect of different energy sources on growth performance, abdominal fat deposition and fatty liv~r syndrome in broilers. I. The effect on growth performance and abdominal fat deposition.(Selçuk Üniversitesi, 1987) Tuncer, Şakir Doğan; Aştı, Reşat; Coşkun, Behiç; Tekeş, Mehmet Ali; Erer, HüdaverdiSummary : This study was carried out to investigate the effects of different energy sources used in broiler diets on the growth performance and the albdominal fat deposition. Four hundred male and 400 female day- old Arbro -7 chicks were randomly distributed by sex into sixteen pens, each pen containing 50 chicksÖğe The Estimation of Trypsin Inhibitor Activities in Soybean Meals Produced in Turkey(Selçuk Üniversitesi, 2020) Şeker, Renan; Tuncer, Şakir DoğanThis study was conducted in order to determine the nutrient contents and some anti-nutritional factors of of soybean and soybean meal produced in the Adana province of Turkey and imported from various countries. Totally 8 samples, consisting of 5 soybean meals, 1 full-fat soybean meal, 2 raw soybeans, were used in this study as research materials. The trypsin inhibitor activities (TIA) and urease activities (UA) were determined as anti-nutritional factors. Additionally, the degrees of changes in these factors were analyzed in the soybeans which were exposed to heat, humidity and pressure. Besides, the cresol red (CR) test was used to estimate the toasting degree of the samples and to compare with other analysis results. The average TIA, UA and CR values in soybean meal of the soya produced in Turkey used in the experiment, were found to be 2.59 mg/g, 0.05 mg N/g/minute and 4.39 mg/g, respectively. TIA, UA and CR values are determined for the imported soybean meal are 1.62 mg/g, 0.082 N/g/minute and 4.45 mg/g respectively. These values are in the same order for for full-fat soybean, 9.60 mg/g, 0.071 mg N/g/minute and 4.43 mg/g. TIA values of raw soybean (1) which were autoclaved for 35 minutes at 100°C, 110°C, 120°C and 130°C were found as 23.20, 10.27, 2.91, 0.53 and 0.20 mg/g respectively. UA values for same raw soybeans were detected as 8.40, 2.36, 0.23, 0.00 and 0.00 mg N/g/min and CR values were found as 2.42, 2.42, 4.22, 4.46 and 4.95 mg/g respectively. TIA values were 30.00, 27.12, 26.74, 26.29 and 22.74 mg/g in the raw Soybean sample that was subjected to dry heat (heated at 100°C, 110°C, 120°C, 130°C). In the raw soybean sample, where dry heat was applied, the UA values were started with no heat applied, respectively, 8.87, 8.87, 8.80, 8.75 and 4.62 mg N/g/min; CR values were found as 3.03, 3.07, 3.07, 3.22 and 3.28 mg/g in the same order.Öğe Farklı Enerji? Kaynaklarının Broylerlerde Besi? Performansı, Abdominal Yağ Birikimi ve Karaciğer Yağlanması Üzerine Etkisi II. Karaciğer Yağlanmasına Etkisi(Selçuk Üniversitesi, 1987 Ocak) Tuncer, Şakir Doğan; Aştı, Reşat; Coşkun, Behiç; Erer, Hüdaverdi; Tekeş, Mehmet AliThis study was carried out to investigate the effects of different energy sources used in broiler diets on occurence of fatty liver syndrome. Four hundred male and 400 femal dayold Arbro 7 were randomly distributed by sex into sixteen pens with each pen containing 50 chicks. In eight experimental rations, 1. Corn (M); 2. Sunflower oil (2.5%) (AY); 3. Sunflower oil (5%) (AY); 4. Fish oil (2.5%) (BY); 5. Fish oil (5 %) BY); 6. Animal fat (2.5%) (HY); 7. Animal fat (5%) (HY); 8. Wheat+Sunflower oil (3%) (BAY) were used as supplemental or based energy sources. Each ration was fed to one male and one female group. Thus, sixteen groups were set up and experiment was ended at the 56th day. At the 56th day of the experiment, the highest liver weights and liver fat percentages of the male chickens were found in BY, and BY, fed fish oil. On the other hand, the highest liver weight was found in BY, and the highest percentage of liver fat was observed in BY, in the females. At the end of the experiment, in macroscopic investigation of livers of the male and female chickens fed fish oil were yellowish pale, swollen and crispy. In microscobic investigation of the livers in the same groups, the excessive amounts of lipid infiltrations were seen in the cytoplasma of paranchymal cells. Simiral observation was found in the livers of female chickens fed corn. There were the excessive amounts of lipid infiltrations in M and BAY in males and in HY, and BAY females, but the lipid level was less than the above groups. By contrast, the lesser amounts of lipid infiltrations were observed in the liver paranchymal cells of the chickens fed the rations supplemented vegetable or animal fat. As a result, because of the best effect on the reduction of fat level obtained with supplementing various levels of sunflower oil, it is suggested that the vegetable oil be used in broiler rations as an energy substitute of some part of corn. On the contrary, fish oil used in broiler rations increased liver fat accumulation and caused fishy smell in meat.Öğe Kuzu Rasyonlarına Degi?şi?k Düzeylerde Katılan Sodyum Bi?karbonatın Besi? Performansına Etki?si?(Selçuk Üniversitesi, 1988 Ocak) Coşkun, Behiç; Tuncer, Şakir Doğan; Tekeş, Mehmet Ali; Akmaz, Ali; İnal, ŞerefThis study was carried out to investigate the effects of different levels of sodium bicarbonate that was added into concentrate mixtures in 0.5 and 1% on growth performance. In the experiment, 42 Akkaraman male lambs with 5.5-6 months old were used. The research works were conducted as 3 groups for the period of 56 days. The ration of the control group did not contain any sodium bicarbonate. The average of final weights of lambs in the groups were 48.08; 46.75 and 47.38 kg respectively (P<0.05). Average daily weight gain was found to be 233 g in the control group; 193 and 207 g in the other groups respectively (P<0.05). The concentrates and wheat straw fed to the lambs ad libitum. Total feed consumption for all groups were 1750; 1773 and 1817 g respectively. Total feed intake per kg weight gain were found to be 7.51; 9.19 and 8.78 kg, respectively.Öğe Sütten Kesi?lmi?ş Akkaraman Kuzularında Sodyum Lasalosi?d'i?n Besi? Performansı Üzeri?ne ve Muhtemel Bi?r Koksi?di?yozi?se Karşı Etki?si?(Selçuk Üniversitesi, 1986 Ocak) Tuncer, Şakir Doğan; Coşkun, Behiç; Cantoray, Rıfat; Tekeş, Mehmet AliThis experiment was carried out to investigate the effects of Na-lasalocid that was added into concentrate mixtures in 25, 50 and 75 g per ton on growth performance and against the possible coccidia infection of lambs. In the experiment, 40 Akkaraman male lambs with 3.5-4 months old were used. The research works were conducted as 4 groups for the period of 84 days. The ration of the control group did not contain any Na-lasalocid. The average of final weights of lambs in the groups were 47.41; 48.91; 49.98 and 49.96 kg respectively, (P>0.05). Average daily weight gain was found to be 260 g in the control group; 262, 281 and 280 g in the other groups, respectively, (P>0.05). The concentrates and wheat straw fed to the lambs ad libitum. Total feed consumption for all groups were 1646, 1648, 1650 and 1709 g respectively. The concentrate intake per kg weight gain were found to be 5.896, 5.744, 5.402 and 5.571 kg, respectively. According to these results, it would asserted that the groups feed with lasalocid improved the feed conversion rate more than the control group at the level of 2.58%, 8.38%, and 5.51%, respectively. The numbers of coccidia oocysts were found to be 6133, 5100, 6000 and 7833 in 1 g of feces sample at the beginning of the experiment. However, the counts of oocysts were sharply reduced after the treatment with Na-lasalocid at all levels. These values were found to be 4033, 38, 30 and 0, respectively, at the end of the experiment. Although 25 g g/ton Na-lasalocid did not improve the growth per- formance, the same level was highly effective in reducing the cocysts counts. On the other hand, spesifically 50 g/ton Na - lasalocid had both possitive effect on growth performance and reducing oocysts numbers. As a result, the use of this level would be strongly recommended in intensive lamb feeding.Öğe Türki?ye'de Üreti?len Pamuk Tohumu Küspeleri?nde Gosipol Düzeyleri?ni?n Tesbi?t Edi?lmesi? Üzeri?nde Bi?r Araştırma(Selçuk Üniversitesi, 1986 Ocak) Tuncer, Şakir Doğan; Yalçın, SakineThis experiment was carried out to determine free and total gossypol contents of cottonseed meals obtained from the different parts of Turkey. Cottonseed meal plays an important role in supplying the protein needs of animals. However gossypol content, especially free gossypol content, is a restricted factor for the usage of this meal. At the end of the experiment, free and total gossypol amounts of extraction cottonseed meal were found as 0.0573 and 0.418%; the amounts of expeller cottonseed meal were also found as 0.0694 and 0.565%, respectively.
