In the current research, it was aimed to determine the effect of the use of under sieve beans, which are not suitable for human consumption, in the diets of growing quails on performance, carcass, and serum parameters. For this purpose, a total of 240-day-old quail chicks were randomly distributed to 6 treatment groups with 40 quail chicks in each, with 4 replicates. In the study, quails were fed with 6 different treatment diets containing 0, 20, 40, 60, 80, or 100 g/kg of under sieve beans. The results of the study demonstrated that the feed intake, mortality, carcass yield, thigh+drumstick, breast, liver, heart weights and serum triglyceride, cholesterol, total protein, albumin, globulin, creatinine, and urea levels of quails were not affected by the use of under sieve beans in the diet. The body weight, body weight gain, and feed conversion ratio were considerably affected by the treatments and the best results in terms of these parameters were obtained in the group using under sieve beans at the level of 40 g/kg. Compared to the control group, pancreas weight increased in the 80 and 100 g/kg under sieve bean groups, while abdominal fat weight decreased in the 100 g/kg under sieve bean group. Serum glucose level increased significantly with the use of under sieve beans in the diet. The serum amylase level, on the other hand, was minimum with the use of 100 g/kg of under sieve beans in the diet. According to the results obtained, it can be said that raw under sieve beans could be used at the level of 40 g/kg without any adverse effects in growing quail diets.

This research was carried out to determine the effects of diets containing different levels of threonine on the performance, carcass characteristics, and serum biochemical parameters of growing Japanese quails. In the study, a total of 240 mixed sex quail chicks at the age of one day were randomly allocated to 6 treatment groups with 4 subgroups. Experimental diets were prepared to contain threonine at 0.84 (without L-threonine addition), 1.02 (control), 1.10, 1.20, 1.30 and 1.40% levels, and quails were fed with these treatment diets for six weeks. The threonine level of the diet did not statistically affect the performance and carcass parameters of quails, but the best feed efficiency was obtained at 1.10% threonine level. While serum cholesterol, total protein, albumin, creatinine, calcium and AST levels were not affected by dietary threonine level, serum glucose, triglyceride, globulin, urea, and phosphorus levels were statistically affected. With 1.30% threonine in the diet, serum glucose and triglyceride levels were minimum, while serum globulin level was maximum. Serum phosphorus level considerably increased at 1.40% threonine level compared to the control group. According to these results, it can be said that the addition of 1.10% threonine to diet would be proper for growing quails.

Bu çalışma büyüyen bıldırcın rasyonlarına farklı seviyelerde arı poleni ilavesinin performans, karkas ve serum biyokimyasal parametreleri üzerine etkilerini belirlemek amacıyla yürütülmüştür. Araştırmada günlük yaşta toplam 240 adet karışık cinsiyette bıldırcın civcivi her birinde 40 civcivin bulunduğu dört tekerrürlü altı muamele grubuna rastgele dağıtılmıştır. Muamele rasyonları bazal rasyona 0, 3, 6, 9, 12 ve 15 g/kg arı poleni ilave edilerek hazırlanmış olup, bıldırcınlar 42 gün süren deneme boyunca bu rasyonlarla yemlenmiştir. Deneme sonunda canlı ağırlık, canlı ağırlık artışı, yem tüketimi ve ölüm oranı gibi performans parametreleri muamelelerden etkilenmezken, rasyona 9 g/kg seviyesinde arı poleni ilavesi ile yemden yararlanma oranı önemli ölçüde iyileşmiştir. Karkas parametrelerinden ise relatif karkas, göğüs ve but+sırt ağırlıkları rasyona farklı seviyelerde arı poleni ilavesinden önemli ölçüde etkilenmiştir. Serum biyokimyasal parametrelerinden yalnızca albümin konsantrasyonu muamelelerden etkilenmiş; rasyona 3 ve 9 g/kg seviyesinde arı poleni ilave edilen gruplarda kontrol grubuna göre önemli ölçüde azalmıştır. Deneme sonuçlarına göre rasyona 9 g/kg arı poleni ilavesinin yemden yararlanma oranına olumlu etkilerinin olduğu söylenebilir.

The present study is designed to attract attention to macroscobic and microscobic findings, causes and economic losses of wooden breast which is a significant muscle problem leading to visual and sensory differences in poultry breast meat quality. Wooden Breast is a crucial problem in poultry industry. It has started to seriously affect poultry production in European and other countries, and especially in United States of America. Woody breast formation is a situation characterized with completely hardened breast fillet or with swelling easily understood when touched. Surface of the fillet contains exudate with petechial bleeding or non-bleeding viscous gelatine. Woody structure called “wooden” can occur not only in breast meat but also in legs. Growth rate, gender, energy level of the feed, amino acid level, and selenium supplement are the factors affecting wooden breast-woody breast meat formation. Shaded colour, surface leak and abnormally hard tissue are seen in macroscopic image of woody breast. In microscopic findings, muscle fibers are less and round. Lesions don’t contain pathogenic micro-organisms, they are aseptic. Colour of the meat of woody breast is brighter and whiter, and (L* value) This muscle problem affects muscles visually and sensorial; but it doesn’t have a negative effect on human health. The more white lines and woody structure in breast meat, the less they are accepted among European consumers.

This study was carried out to determine the influence of different levels of alfalfa meal and the addition of enzyme on performance, carcass and intestinal parameters in growing quails. Japanese quails (n=240), 1 days of age, were divided into 6 dietary treatment groups and the experiment lasted for 5 weeks. In each experiment group there were 4 replicates, and in each replicates there were 10 chicks. Six diets, arranged a factorial design with three alfalfa meal levels (0, 2.5 and 5.0 %) and two levels of added enzyme (0.0 and 1.0 g/kg) were used. The treatments did not effect on the body weight, feed intake and feed conversion ratio. However, relative liver, leg+back, intestine weights and crypt depth were significantly increased, and relative heart and breast weights and villus width decreased by dietary alfalfa meal levels. The addition of enzyme to diets containing alfalfa meal did not affect the performance and carcass parameters, but reduced the intestinal histomorphology parameters in quails. According to the results obtained from the experiment, it can be said that the use of alfalfa meal in growing quail diets did not affect the performance, but the use of alfalfa meal at the level of 2.5% in the diet promotes intestinal development.

Bu çalışmada 8. hafta canlı ağırlık tartımlarına göre sınıflandırılarak büyütülen kazların 16. hafta kesim yaşında performans özellikleri ile göğüs ve but etinde renk ve pH değerlerinin belirlenmesi amaçlanmıştır. Çalışmaya günlük 478 adet palaz ile (dişi-erkek karışık) başlanmıştır. 8. Haftada canlı ağırlığa göre sınıflandırma (hafif, orta ağır, ağır) yapıldıktan sonra 270 adet kaz (dişi-erkek karışık) ile çalışmaya devam edilmiştir. 10. ve 16. haftalarda, ağır grupta canlı ağırlığın daha yüksek olduğu ve hafif grupta ise canlı ağırlık artışının daha yüksek olduğu belirlenmiştir. Yemden yararlanma oranı da hafif ve orta ağır grupta daha düşük bulunmuştur. Ayak ve but ağırlığı ile göğüs pH değeri ağır grupta, abdominal yağ ağırlığı ve oranı orta ağır grupta, baş oranı hafif grupta daha yüksek tespit edilmiştir. Sonuç olarak, sınıflandırmalı büyütmenin hafif grupta canlı ağırlık artışı üzerine etkisi olumludur. Kaz yetiştiriciliğinde hedef kesim canlı ağırlıklarına üniform olarak ulaşmak için bu yöntemden faydalanılabilir.
