Struggling behavior in shackled male and female broiler chickens.
Anecdotal evidence suggests that the struggling behavior of shackled broiler chickens may be positively related to compression of the shank and the probable associated discomfort: birds with large shanks tend to struggle more violently than do those with smaller shanks. Males are generally heavier and have thicker shanks than females. Therefore, we tested the hypothesis that, because the leg ga...
متن کاملActivity Analysis in Broiler Chickens with Different Gait Scores
Monitoring the activity of broilers is a potential way for determining gait score level at commercial farms. In this study, a fully-automatic monitoring technique was developed to measure the activity of broiler chickens with different gait score levels. We carried out experiments in order to assess the relationship between gait scores obtained by human experts and activity levels quantified by...
متن کاملOchratoxicosis in Broiler Chickens:
This experiment was conducted to evaluate the effects of ochratoxin A (OTA) on the function and histology of the liver, kidney and bursa of broiler chickens fed OTA contaminated rations. Two hundred forty one-day-old male Ross broiler chicks were used, they were randomly divided into 3 dietary experimental groups of 80 birds and given rations containing 0 (control), 400 or 800 μg OTA/Kg feed. T...
متن کاملThreonine needs of broiler chickens with different growth rates.
The Thr needs in 3 commercial broiler strains (A, multipurpose; B, high yield; C, high yield) known to differ in terms of feed intake, growth rate, and breast yield were evaluated. Birds were randomized across 96 floor pens (12 birds/pen), received a common diet from d 1 to 20, and were fed graduations of Thr (0.52 to 0.87% total Thr in 0.07% increments) from d 21 to 42. Treatments (3 x 6 facto...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
