This experiment was conducted to investigate the effects of treatment of wheat straw with aqueous ammonia on its digestibility and feed intake and weight gain of beef cattle fed two level of concentrate mixture. About five tones wheat straw stack treated with 40 g aqueous ammonia contains 25 % NH3 per kg straw for 30 days after covering the stack with plastic sheet. The digestibilities of untreated and treated straw was determined with four Merino rams. The digestibilities of dry matter, crude protein, crude fibre, organic matter were 47.74, 58.80, 58.83 and 49.22 % for untreated straw and 49.59, 73.42, 63.35, 52.92 % for treated straw, respectively. In the feeding experiment, 28 bulls were allocated to four groups each of 7 bulls. Two level of concentrate mixture and two straw (treated and untreated) were given with a 2x2 factorial arrangement. The ammonia treatment decreased straw intake. No differences in the live weights gain were found among the groups.

(Selçuk Üniversitesi, 1993) Coşkun, Behiç; İnal, Fatma; Şeker, Erdoğan; Gülşen, Nurettin; Arık, H. Derya
In this study, the effects of seaweed soluble powder (maxicrop), used as growth promoter in plants on egg production, feed intake, feed efficiency and egg yolk color in hens were investigated Total 108 hens aged 44 weeks were used and three groups were designed During 12 weeks, the animals fed control feed, the feed containing 0.1 % and 1 % seaweed powder. Later, all groups fed control ration during 5 weeks. In first period, average egg production in groups were 68.23, 74.45 and 62 05 %, respectively (p<0.05) Feed intake for 1 kg eggs was lower in the group fed % 0.1 seaweed powder. It was found, the seaweed powder affected positively to yolk color, but didn't to feed intake. As a result, to increase egg yield, seaweed powder may use in poultry diets but it is needed additional researches about this area.

This 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.

This study was carried out to investigate the effects of sunflower oil and tallow or their different com- binations on the growth performance and mortalite in broiler rations. A total of 560 chicks were divided into four groups each containing 140 animals. The ratios of the groups were added 4.5% sunflower oil, 0.45 % sunflower oil + 4.05% tallow. 0.9 % sunflower oil + 3.6 % tallow and 4.5[3] tallow. The trial was lasted in 42 days. At the end of the experiment, body weights were 1718.52 1828,50, 1771 15 and 1816.38 g (P < 0.05) Feed consumption of the groups were 69.93, 74.74. 73.43 and 76.01 g: feed conversion 1 75, 1.75, 1.78 and 1.80 kg, respectively. Mortalite were detected to be as 2. 14, 142. 2 14 and 2.85 %, respectively. In conclusion, the tallow can be replaced with sunflower oil in broiler ratios. To add sunflower oil to tallow in 10% quantity could effect performance in a positive manner while no negative effect on mortality by adding 10% sunflower oil was observed.

(Selçuk Üniversitesi, 1995 Nisan) Balevi, Tahir; Coşkun, Behiç; Aktümsek, Abdurrahman
Totaly, 184 broiler chicks were used in this investigation in which the availability of by-products of oil industry in broiler rations was investigated. The growth performance, weight of carcass and abdominal fat and amounts of fatty acids in abdominal fat of broilers fed diets consisting 5 % sunflower crude oil, sunflower soapstock, acidulated sunflower soapstock and volatile matters were determined. The trial was lasted in 49 days. The highest feed consumption and feed efficiency values were determined in broiler group fed acidulated soapstock. The lowest feed consumption and the highest average live weight values were found in the group fed the diet containing sunflower crude oil. It was concluded that the use of by-products of oil industry in broiler diets as energy source will use without any harmful effect on broiler performance and contain more omega-3 fatty acids which is very important for human health.

(Selçuk Üniversitesi, 1987 Ocak) Aştı, Reşat; Tuncer, Şakir Doğan; Coşkun, Behiç; Başpınar, Nuri; Çelik, İlhami; Kalaycıoğlu, Leyla
This 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.

(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2016) Alataş, Mustafa Selçuk; Kara, Kanber; İnal, Fatma; Kahraman, Oğuzhan; Özbilgin, Abdullah; Coşkun, Behiç
In this study, our aim was to compare estimated metabolizable energy (ME) and net energy lactation (NEL) contents in dried alfalfa samples in their different growth stages, using models such as NRC-2001, Hohenheim(Menke) and University of California at Davis (UC Davis). A total of 73 alfalfa hay samples obtained during three different growth stages (Vegetative, Bud and Bloom) were used. Chemical analyses were performed for each sample. Energy values of the alfalfa hay samples were calculated with NRC-2001 equations from chemical analysis results, and with HohenheimMenke and UC Davis equations from in vitro gas production volumes. Gas production in alfalfa samples in vegetative period (S1) was higher than other periods (P<0.001). Again, ME values calculated with all three methods in the alfalfa hay samples of this period were significantly higher than the samples in bud and bloom periods (P<0.001). In addition, energy values obtained with HohenheimMenke equation in all periods were found to be higher than the averages obtained with NRC-2001 and UC Davis equations. It is concluded that, for the alfalfas in vegetative period, a correlation of 85.6% between energy values obtained with NRC-2001 and HohenheimMenke equations, a correlation of 81.8% between energy values obtained with UC Davis and NRC-2001 equations, and over 99% correlation between energy values obtained with HohenheimMenke and UC Davis equations were determined (P<0.000).

(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2015) İnal, Fatma; Gürbüz, Emel; Coşkun, Behiç; Alataş, Mustafa Selçuk
The objective of this study was to develop a reliable and cheap method to determine of milk urea nitrogen and compare some other instrumental methods. Two trials were conducted. In first trial, a milk urea nitrogen testing method was designed by modifying some methods developed for ammonia nitrogen testing method. Several studies were performed for the validation of method. By using standard solutions some applications such as determinability, recovery, repeatability, test of various analyzers and devices, limit of quantification were performed. Recovery of added urea averaged 99.38 %. In second trial, 105 individual milk samples from a dairy farm was analyzed for milk urea nitrogen by modified indophenol, infrared, and MiniFoodLab methods. The means of milk urea nitrogen obtained from three different methods were 23.87, 21.59, and 23.92 mg/dl, respectively. There was a positive correlation between modified indophenol and infrared methods.
Conservation characteristics and protein fractions of cereal silages ensiled with additives at the booting and dough stages of maturity
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2014) Keleş, Gürhan; Coşkun, Behiç; İnal, Fatma; Alataş, Mustafa Selçuk; Ateş, Serkan
The experiment was conducted to investigate the effects of organic acid and bacterial inoculant on conservation characteristics and protein fractions as defined by the Cornell Net Carbohydrate and Protein System of barley, wheat, rye, triticale, and oat silages ensiled at their booting or dough stage of maturity. The cereal crops were not treated or were treated with bacteria (L. buchneri, L. plantarum, E. faecium) or organic acid (formic acid, propionic acid, sodium formate) and ensiled in 1.0-L anaerobic jars for 45 days. Bacterial inoculant improved the fermentation profile for all cereal silages and increased the dry matter (DM) recovery at both maturity stages. The benefit of bacteria inclusion in the silage was more pronounced when applied at dough stages. Organic acid also improved the fermentation profile for all cereal silages, but it was less effective than the bacteria at both booting and dough stages of maturity. The reduction (P < 0.001) in in vitro DM digestibility was not as sharp as the decrease in crude protein (CP). Protein A fraction and digestible CP were higher (P < 0.001) at the booting stage, while all B fractions and C fraction were higher (P < 0.001) in cereal silages ensiled at the dough stage. It was concluded that additives, in particular bacterial inoculant, can improve fermentation and protein quality at both stages examined.

(TAYLOR & FRANCIS LTD, 2018) İnal, Fatma; Tamkoç, Ahmet; Alataş, Mustafa Selçuk; Kahraman, Oğuzhan; Özbilgin, Abdullah; Coşkun, Behiç
This study was conducted to determine the effect of different vegetative periods on protein fractions of alfalfa hay and to compare two different methods for estimation of its protein degradability. In this study, 44 alfalfa hay samples cut in late vegetative, late bud, early bloom and late bloom were used. Crude protein decreased with advancing maturity (p<.05), but neutral detergent insoluble nitrogen and acid detergent insoluble nitrogen were similar. Protein degradability of the samples was estimated using Streptomyces griseus protease or borate-phosphate buffer, kinetic model, as described in Cornell Net Carbohydrate Protein System (CNCPS). Alfalfa hay samples were subjected to proteolysis for 30h with 0.115 U/mL or 0.230 U/mL of the protease at pH 6.8. There was a moderate correlation (0.66, 0.72) between enzymatic and buffer method estimates with protein degradation. As vegetation progresses, rapidly degradable fraction (A) decreased (p < .05) and undegradable fraction (C) increased (p < .05), while potentially degradable fraction (B) was unchanged. Rumen degradable protein content decreased (p < .05) with advancing maturity. The enzyme/duration limits should be standardised and investigated whether the protease enzyme alone is sufficient for all forages.

This study was conducted to determine body characteristics and speeds of Rahvan horses racing at Pace Horse Races in Turkey. A total of 1258 Rahvan horses racing at 20 pace races between 1 999 and 2000 years in Turkey were inspected. The speeds of 125 winner horses and body measurements of 120 Rahvan horses were determined. The speeds of winner horses racing at different native categories were calculated as 21.66-34.20 km h(-1) for Tozkoparan, 25.11-37.04 km h(-1) for Deste, 28.97-39.07 km h(-1) for Kucuk orta, 30.20-36.63 km h(-1) for Buyuk orta, 27.05-43.06 km h(-1) for Bas alti, 32.26-40.52 km h(-1) for Has, respectively. The averages of head length, neck length, height at withers, body length, height at rump, heart girth circumference, chest depth, chest width and cannon bone circumference as body measurements were found as 56.49, 69.80, 139.21, 141.60, 138.28, 155.30, 58.38, 34.24 and 17.69 cm, respectively. There is no significantly difference for inspected body measurements among age or sex groups, except for cannon bone circumference. The averages of cannon bone circumference of 3 years old horses and mares were found as lower than the others (p<0.05). And the ratio of height at rump to height at withers in mares was higher than stallions (p<0.05). The Pacing speed of Turkish Rahvan Horses was found as lower than the other breeds that can pace in. the World. It was concluded that Turkish Rahvan Horses should be improved with respect to increase height at withers and to lengthen and to thin neck.

(Scientific Technical Research Council Turkey, 2000) İmik, Halit; Aytaç, Melik; Coşkun, Behiç; Fidancı, Hatice
The aim of this study was to determine the effects of administration of vitamin E and C on the live weight gain, antibody levels against Brucella melitensis (Rev. I) vaccine and liveability of Angora goat kids separated from their mothers at the age of 21 days, and then exposed to stress. Forty kids were used in this study. They were divided into four groups having ten kids per group. This study was conducted with the control group (+) in which the kids were not separated from their mothers until the weaning period, a group(-) which was exposed to stress and being with their mothers only 15 minutes a day from average 21 days age to weaning, and a groups of vitamin E and vitamin C. Live weights in the groups were 14.9, 11.0, 11.3 and 12.3 kg respectively, at the end of this study. As regards to live weights, there were statistically significant differences among the control (+), control (-) and vitamin E groups (p<0.05); where as there were no statistically significant differences between these groups and vitamin C. Daily live weight gains of the groups were found to be 80.7, 39.3, 49.8 and 53.6 grams respectively. There were statistically significant differences between the control (+) group and the others (p<0.05). The control group (+) vaccinated with Rev 1 had statistically significant positive antibody levels (<+/40) compared with the other groups (p<0.05). Because of the effect of increasing stress factors, the kids were infected with coccidioses after weaning. In the groups, 0, 6, 4 and 2 animals died because of the coccidioses respectively. There were no statistically significant differences among the groups in terms of mohair quality.

(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2010) İnal, Fatma; Gürbüz, Emel; Coşkun, Behiç; Alataş, Mustafa Selçuk; Çitil, Özcan Barış; Polat, Esad Sami; Şeker, Erdoğan
This study was carried out in two experiments. Experiment 1 was conducted with six ruminally-cannulated one-year old Kangal Akkaraman male lambs, using a crossover design with 2 periods to determine the effects of live yeast culture supplementation on rumen fermentation. Yearlings were either supplemented with 4 g/d of Saccharomyces cerevisiae (BeneSacc, 4x10(9) CFU/g) or not supplemented (control). Animals were penned individually, and were fed a diet composed of 25% forage and 75% concentrate for sixteen days. Rumen fluid was sampled on day 16, 0 h (before feeding), 3 h and 6 h after feeding. Rumen pH, the numbers of protozoa, ammonia-N and volatile fatty acids (VFA) were determined in samples. Molar proportions of acetate were decreased, and propionate was increased with supplementation of live yeast culture. No differences were observed for ruminal pH, protozoa population, total VFA and ammonia-N concentrations, between treatments. In Experiment 2, in situ nutrient degradability of barley grain, corn dried distillers grains with solubles (DDGS) and wheat straw were determined. Live yeast culture supplementation did not affect dry matter (DM) degradability of barley, DDGS or straw, crude protein (CP) degradability of DDGS, nor neutral detergent fiber (NDF) degradability of straw. But, it reduced the potential degradability of DDGS in rumen..
