In this research, 30 Gurcu goats, which are kept in the Kafkas University Veterinary Faculty farm, were used. During the grass and pasture feeding, the animals were fed by grazing in the natural meadows and pasture. And also before and after the grass and pasture, they were fed with grasses that were dried by mowing from these area. Crucial metabolic values were measured by taking blood samples from goats before grass and pasture feeding, during grass and pasture feeding, and post grass and pasture feeding. When the results from collected samples during these different feeding intervals are analyzed, significant differences in NEFA, BHBA, total cholesterol, and urea were observed (P 0.05). With this research, it has been concluded that depending on the nutritional conditions, changes may occur in the metabolic profile of the Gurcu goat depending on t...

The experiment was conducted with four groups in total, including one control and three experimental groups. All the groups were divided into four subgroups , each consisting of 12 chicks, and the total number of chicks in each group was determined to be 48. No additives were added to the feeds of the control group throughout the research. 0.3 g/kg (Bet-0.3), 0.5 g/kg (Bet-0.5) and 0.8 g/kg (Bet-0.8) betaine (Betamar®) were added to the rations of the experimental groups, respectively. Rations were prepared as isocaloric and isonitrogenic. The animals were given feed and water ad-libitum. In the study, The rations containing crude protein (CP) of 23% and3000 kcal/kg metabolic energy (ME)until the day 1-21 and CP of 20% and3224 kcal/kg ME until the day 22-42 days were given in the treatment groups. At the end of the study, statistically significant differences were observed in the experimental groups in terms of body weight (BW) and body weight gain (BWG) when compared with the control group. The highest BW and the highest BWG were observed in the Bet-0.8 experimental group. No statistically significant difference was found in terms of feed consumption, feed conversion ratio, carcass characteristics, weights of some internal organs, and serum blood parameters (P>0.05). It was concluded that adding 0.8 g/kg betaine to broiler rations increase fattening performance and can be used safely.

One hundred ninety-two 7-day-old chickens were randomly distributed into four groups having four replicates with 12 birds in each replicate. Basal diets were prepared for starter (days 8 to 21) and finisher (days 22 to 42). Basal diets were offered to the control group only, whereas other treatments received basal diets fortified with 0.5, 1, and 2% blueberry extract (BB0.5, BB1, and BB2 groups, respectively). The duration of experiment was 35 days (days 8 to 42). During finisher and overall growth phases, broilers in the BB2 group had greater body weight gain than those in the BB0.5 and control groups, whereas the BB1 group had higher body weight gain than the control group (P < 0.001). Body weight gain remained unaffected during the starter phase. Feed intake was greater in the BB2 group than in the control group at days 8 to 21, 22 to 42, and 8 to 42 (P = 0.002, P = 0.035, and P = 0.001, respectively). The control group had poor FCR than the BB2 group in the starter phase (P = 0.034). At days 22 to 42, feeding blueberry extract (BB0.5, BB1, and BB2) improved the FCR of broilers compared with the control group, whereas the BB2 group had better FCR than the BB0.5 group (P < 0.001). At 8 to 42 days, broilers in the control group had poor FCR compared with the BB1 and BB2 groups, whereas the BB0.5 group had poor FCR than the BB2 group (P < 0.001). Slaughter weight was lower in the control group than in the blueberry extract groups, whereas the BB2 group had greater slaughter weight than the BB0.5 group (P < 0.001). Dressing percentage of broilers in the control and BB0.5 groups was lower than that in other groups (P < 0.001). Gizzard yield was higher in the BB0.5 and BB2 groups than in the control group (P = 0.021). In addition, feeding 2% blueberry extract increased the concentration of different fatty acids in breast and thigh meat of broiler chickens. Findings suggest that feeding 2% blueberry extract may improve growth performance, carcass characteristics, and fatty acid composition of breast and thigh muscles of broilers.

The study material was composed one control (0% WV) and three experimental groups consisting of 0.5%, 1% and 2% WV, respectively. Each group was made with four replicates. WV was applied to the grass prepared from the natural meadow of Kafkas University and prepared in the laboratory scale conditions by spray method at given rates (0.5%, 1% and 2%). The samples were ensiled in 1.0 L anaerobic jars. pH, dry matter, crude protein, crude fat, crude ash, acid detergent fiber and neutral detergent fiber analyses were performed on the samples opened on the 60 th day of fermentation. Also, microbiological analyses were performed for lactic acid bacteria, yeast, and mold by the plate count method. As a result of silage trials carried out under laboratory-scale conditions, WV did not affect nutritional values (P>0.05). The highest pH among the treatment groups was observed in the 2% WV added group (P<0.05). While the number of lactic acid bacteria in the WV groups (0.5 and 1%) did not change when compared to the control group (P>0.05), the highest (2%) concentration of WV showed significant antimicrobial activity on lactic acid bacteria (P<0.05). Also, it has been determined that WV may reduce yeast and mold growth compared to the control group (P<0.05).

The experiment was conducted with four groups in total, including one control and three experimental groups. All the groups were divided into four subgroups , each consisting of 12 chicks, and the total number of chicks in each group was determined to be 48. No additives were added to the feeds of the control group throughout the research. 0.3 g/kg (Bet-0.3), 0.5 g/kg (Bet-0.5) and 0.8 g/kg (Bet-0.8) betaine (Betamar®) were added to the rations of the experimental groups, respectively. Rations were prepared as isocaloric and isonitrogenic. The animals were given feed and water ad-libitum. In the study, The rations containing crude protein (CP) of 23% and3000 kcal/kg metabolic energy (ME)until the day 1-21 and CP of 20% and3224 kcal/kg ME until the day 22-42 days were given in the treatment groups. At the end of the study, statistically significant differences were observed in the experimental groups in terms of body weight (BW) and body weight gain (BWG) when compared with the control group. The highest BW and the highest BWG were observed in the Bet-0.8 experimental group. No statistically significant difference was found in terms of feed consumption, feed conversion ratio, carcass characteristics, weights of some internal organs, and serum blood parameters (P>0.05). It was concluded that adding 0.8 g/kg betaine to broiler rations increase fattening performance and can be used safely.
The effect of gradually increasing supplemental levels of blueberry extract on growth performance... more The effect of gradually increasing supplemental levels of blueberry extract on growth performance, carcass characteristics, and fatty acid composition of breast and thigh muscles of broiler chickens was investigated. One hundred ninety-two 7-day-old chickens were randomly distributed into four groups having four replicates with 12 birds in each replicate. Basal diets were prepared for starter (days 8 to 21) and finisher (days 22 to 42). Basal diets were offered to the control group only, whereas other treatments received basal diets fortified with 0.5, 1, and 2% blueberry extract (BB0.5, BB1, and BB2 groups, respectively). The duration of experiment was 35 days (days 8 to 42). During finisher and overall growth phases, broilers in the BB2 group had greater body weight gain than those in the BB0.5 and control groups, whereas the BB1 group had higher body weight gain than the control group (P < 0.001). Body weight gain remained unaffected during the starter phase. Feed intake was greater in the BB2 group than in the control group at days 8 to 21, 22 to 42, and 8 to 42 (P = 0.002, P = 0.035, and P = 0.001, respectively). The control group had poor FCR than the BB2 group in the starter phase (P = 0.034). At days 22 to 42, feeding blueberry extract (BB0.5, BB1, and BB2) improved the FCR of broilers compared with the control group, whereas the BB2 group had better FCR than the BB0.5 group (P < 0.001). At 8 to 42 days, broilers in the control group had poor FCR compared with the BB1 and BB2 groups, whereas the BB0.5 group had poor FCR than the BB2 group (P < 0.001). Slaughter weight was lower in the control group than in the blueberry extract groups, whereas the BB2 group had greater slaughter weight than the BB0.5 group (P < 0.001). Dressing percentage of broilers in the control and BB0.5 groups was lower than that in other groups (P < 0.001). Gizzard yield was higher in the BB0.5 and BB2 groups than in the control group (P = 0.021). In addition, feeding 2% blueberry extract increased the concentration of different fatty acids in breast and thigh meat of broiler chickens. Findings suggest that feeding 2% blueberry extract may improve growth performance, carcass characteristics, and fatty acid composition of breast and thigh muscles of broilers.

Materyal ve Metot: Araştırmada, günlük yaşta 192 adet karışık cinsiyette civciv kullanılmıştır. Denemede 48'er civcivden oluşan 1 kontrol ve 3 adet deneme grubu olmak üzere toplam 4 grup oluşturulmuştur. Her grup 12'şerli 4 alt gruba ayrılmıştır. Çalışma toplam 42 gün sürdürülmüştür. Kontrol grubuna bazal rasyon verilirken, diğer üç deneme gruplarına sırasıyla kekik yağı ve keçiboynuzu tozu karışımı içeren rasyonlar verilmiştir (0.5, 1 ve 2 g/kg). Hayvanlara yem ve su ad-libitum sağlanmıştır. Gruplara 1-14. gün yapısında % 23 ham protein (HP) 3000 kcal/kg metabolik enerji (ME), 15-28. Gün %21 HP 3100 kcal/kg ME ve 29-42.gün % 20 HP 3200 kcal/kg ME içeren rasyonlar verilmiştir. Bulgular: Deneme sonunda, kontrol grubuna oranla deneme gruplarında canlı ağırlık (CA), canlı ağırlık artışı (CAA), yem tüketimi (YT), yemden yararlanma oranı (YYO), karkas ve iç organ ağırlıkları bakımından istatistiksel olarak farklılık bulunmamıştır (P >0.05). Sonuç: Bu çalışmada, kekik yağı ve keçiboynuzu tozu karışımının broyler karma yemlerinde 1 g/kg düzeyinde güvenli bir şekilde ilave edilebileceği kanaatine varılmıştır.

The study material was composed one control (0% WV) and three experimental groups consisting of 0.5%, 1% and 2% WV, respectively. Each group was made with four replicates. WV was applied to the grass prepared from the natural meadow of Kafkas University and prepared in the laboratory scale conditions by spray method at given rates (0.5%, 1% and 2%). The samples were ensiled in 1.0 L anaerobic jars. pH, dry matter, crude protein, crude fat, crude ash, acid detergent fiber and neutral detergent fiber analyses were performed on the samples opened on the 60 th day of fermentation. Also, microbiological analyses were performed for lactic acid bacteria, yeast, and mold by the plate count method. As a result of silage trials carried out under laboratory-scale conditions, WV did not affect nutritional values (P>0.05). The highest pH among the treatment groups was observed in the 2% WV added group (P<0.05). While the number of lactic acid bacteria in the WV groups (0.5 and 1%) did not change when compared to the control group (P>0.05), the highest (2%) concentration of WV showed significant antimicrobial activity on lactic acid bacteria (P<0.05). Also, it has been determined that WV may reduce yeast and mold growth compared to the control group (P<0.05).

A total of 200 quails were distributed at equal body weights into four experimental groups, each consisting of five replicate pens having ten birds/replicate pen: 1-basal diet without Res (Control), 2-basal diet + 100 mg/kg Res, 3-basal diet + 200 mg/kg Res, and 4-basal diet + 400 mg/kg Res. There were no significant effects of the supplementation of resveratrol on body weight gain and carcass traits (P>0.05). Inclusion of Res in quail rations improved feed consumption (P<0.05) and feed conversion ratio during the period from 3 to 5 weeks and the throughout (0-5 wks) of the treatment (P<0.05). Malondialdehyde decreased as compared with the control group (P<0.05), but glutathione and nitric oxide did not change by the effect of Res (P>0.05). Glucose, triglyceride, total protein was not influenced by the supplementation of Res (P>0.05). As a result, the findings of this study suggest that Res can be used safely as a growth promoter up to 400 mg/kg in quail rations.
