comparison of gompertz and artificial neutral network models of broiler growth received artichoke extract in their drinking water
نویسندگان
چکیده
an experiment was carried out to estimate growth parameters of broiler chickens received artichoke extract in their drinking water using gompertz non-linear model and to compare gompertz non-linear regression equation and artificial neural network modeling in terms of their ability to predict body weight of broiler chicks at day 42 of age. a total number of 250 one- day- old ross 308 broiler chicks were used. the chicks received artichoke extract in their drinking water at the doses of 0, 100, 200, 300 and 500 mg per liter. the birds were weighed at days 1, 2, 7, 14, 21, 24, 27, 30, 33, 35 and 42 of experimental period after 3 hours of fasting. estimated mature body weight was significantly higher in birds received 200 mg/liter artichoke extract in drinking water than the other birds (p

Comparison of Gompertz and neural network models of broiler growth.
Neural networks offer an alternative to regression analysis for biological growth modeling. Very little research has been conducted to model animal growth using artificial neural networks. Twenty-five male chicks (Ross x Ross 308) were raised in an environmental chamber. Body weights were determined daily and feed and water were provided ad libitum. The birds were fed a starter diet (23% CP and...

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Comparison of the Accuracy of Nonlinear Models and Artificial Neural Network in the Performance Prediction of Ross 308 Broiler Chickens
This study aimed to investigate and compare nonlinear growth models (NLMs) with the predicted performance of broilers using an artificial neural network (ANN). Six hundred forty broiler chicks were sexed and randomly reared in 32 separate pens as a factorial experiment with 4 treatments and 4 replicates including 20 birds per pen in a 42-day period. Treatments consisted of 2 metabolic energy le...
