Mustard contains toxic substances e.g. glucosinolate, erucic acid, sinapine and tannin. The substances induce unpalatability, growth retardation, low feed efficiency, thyroid gland enlargement and reproductive problems, particularly when the seed is incorporated in the diet at high levels (19, 26). The FeSO4 treatment of mustard meal is an effective method of detoxification of the meal for using in poultry diets. It can reduce the oxazolidinethione content of the meal by about 88% and the isothiocyanate content by 74% (8). As mustard seeds are available at a lower price than canola seed, in some regions of Iran, this study was conducted to investigate the effects of different dietary levels of wild black mustard seeds treated with FeSO4 on growth performance, blood metabolites, carcass characteristics and meat quality of Japanese quails. Materials and methods: Two-hundred Japanese quails of age seven-day old were randomly assigned to 4 treatment groups with 15 birds in each one of them. The experiment consists of 4 replicates in a completely randomized design. Mustard seeds were treated with FeS04-7H2O according to Daghir and Nawazish (8) procedure. Experimental treatments consisted of control diet (without mustard seed) and diets contained treated mustard seed at 5, 10 and 15% levels. The experimental period lasted up to the age of 35 days. The rearing and management conditions were the same for all groups. Experimental diets were formulated to meet the nutrients requirements of the Japanese quails (20). Chicks had free access to feed and water during the experimental period. Live body weight and feed intake were recorded weekly. On days 35 of the experimental period, blood samples of one male bird per cage (four birds per treatment) were collected to determine the blood metabolites. After slaughtering, breast muscle was separated and kept frozen at -18°C for 30 days. Breast muscle lipid peroxidation was assessed as thiobarbituric acid-reactive substance concentrations in samples by the method of Tarladgis et al. (27). The breast muscles samples were also used for pH (16), water holding capacity, drip loss (7) and cooking loss (4) tests. Results and discussion: Percentage of crude protein, ether extract, ash, moisture, and AMEn (Kcal/Kg) of the experimental mustard seed were 28.6, 40.3, 5, 7, 14.8 and 4630, respectively. Using different levels of processed mustard seed had no significant effects on growth performance compared to the control. Using untreated mustard seed (10) and mustard meal (6, 21) at more than 10 percent had detrimental effects on performance. However, it seems that using 15% treated mustard had no adverse effect on growth performance. Relative weights of the carcass traits (thigh, breast, heart, testis, gizzard, cecum and small intestine) were not significantly affected by the treatments. However, the weight of pancreas tended to be heavier in the birds fed mustard seed (P}, keywords = {Blood parameters,Growth performance,Japanese quail,Processed mustard seed}, title_fa = {مطالعه تاثیر سطوح مختلف دانه خردل فرآوری شده با سولفات آهن بر عملکرد و برخی فرآسنجه‌های خونی در بلدرچین ژاپنی}, abstract_fa = {این مطالعه به منظور بررسی ارزش تغذیه‌ای دانه خردل سیاه فرآوری شده با یک درصد سولفات آهن در سطوح صفر، 5، 10 و 15 درصد بر پارامترهای عملکرد رشد، برخی فراسنجه‌های خونی، کیفیت گوشت و هزینه خوراک به ازای هر کیلو گرم وزن زنده در بلدرچین‌های ژاپنی انجام شد. به این منظور از 240 قطعه جوجه بلدرچین ژاپنی یک روزه در قالب طرح کاملا تصادفی با 4 تیمار و 4 تکرار، از سن 35-7 روزگی استفاده شد. پروتئین خام، عصاره اتری، خاکستر، رطوبت و الیاف خام در ماده خشک دانه خردل به ترتیب، 6/28، 3/40، 5، 7 و 8/14 درصد و ارزش انرژی قابل سوخت و ساز ظاهری تصحیح شده برای نیتروژن آن بر اساس ماده خشک 4630 کیلوکالری بر کیلوگرم بود. مصرف سطوح مختلف دانه خردل فرآوری شده، اثر معنی‌داری بر مصرف خوراک، افزایش وزن روزانه و ضریب تبدیل نداشت. وزن نسبی قلب، کبد، دستگاه گوارش و وزن قطعات لاشه به طور معنی‌داری تحت تاثیر تغذیه سطوح مختلف خردل فرآوری قرار نگرفت، اما وزن نسبی پانکراس افزایش نشان داد. تیمارهای غذایی تاثیر معنی‌داری بر میزان مالون‌دی‌آلدهاید، پی‌اچ و سایر پارامترهای کیفیت گوشت (افت خونابه، افت در نتیجه پخت و ظرفیت نگهداری آب) نداشتند. از نظر اقتصادی هزینه خوراک برای تولید یک کیلو وزن زنده با استفاده از دانه خردل فرآوری شده در سطح 10 درصد کمترین هزینه را داشت. لذا استفاده از دانه خردل فراوری شده تا سطح 10 درصد، اقتصادی‌تر به نظر می‌رسد.}, keywords_fa = {بلدرچین ژاپنی,پارامترهای خونی,دانه خردل فراوری شده,عملکرد رشد}, url = {https://ijasr.um.ac.ir/article_34607.html}, eprint = {https://ijasr.um.ac.ir/article_34607_8ddee7fa00d1ecc1cba9dc4642461637.pdf} }
