Evaluation of Supplemented Various Levels of Oil, Seeds and Fruits of Local Bitter Melon ( Citrullus Colocynthis) in Diet of Japanese Quail(Coturnix japonica):1-Productive Performance and some of carcass characteristics

Abstract

The experiment were conducted to investigate the effect of dietary supplementation with different levels of seed, fruits meal, oil and their combination of Bitter melon (Citrullus colocynthis) on productive performance and some of carcass characteristics of Japanese quail .The experiment was carried out at the Quail Farm, College of Agriculture, University of Basra from 1/11/2015 to 26/12/2015. A total of 288 unsexed one day old quail chicks were used in this study from private hatchery which located on the Omara City. The rate of weight was 8 g/chick. At 14 days were randomly distributed on 24 cages (12 chick/cage), with three replicate for each treatment in a Complete Randomized Design (CRD). Chicks fed during the incubation period in a free commercial diet containing 22.71% crude protein and 3026 Kcal/Kg metabolic energy. And at two weeks of age were fed eight experimental diets, the first treatment was control (basal diets) contented 21.99 % crude protein and 3042 Kcal/Kg metabolic energy. Basel diets supplemented with 1.5 and 3 % bitter melon seed powder in treatment T2 , T3 and with %1.5 and 3 % bitter melon seed oil in treatment T4, T5 and with bitter melon fruit powder in same levels at treatment T6, T7 respectively, while in T8 basal diet supplemented with mixture of seeds, fruit and oil at level of %1 each. The results showed significant differences (P≤0.05) between the experimental treatments in average final body weight (8wks), weight gains at 3-8weeks and in feed intake in all periods except sixth wks. in Japanese quail. No significant differences were revealed in feed conversion ratio during the period 5-6 weeks of age, whereas there were significant differences (P≤0.05) at the other remaining experimental periods. Significant increase (p≤0.05) were appeared in carcass weight, dressing percentage, relative weight of thigh in T4 and T5 which recorded the highest percent as compared to control, while there was significant decrease in relative weight of liver in T4, T5, T6, T7 and T8 and in amount of abominate fat in all supplemented diet as compared to control. No significant differences on relative weight and length of ileum ,relative weight of duodenum and jejunum, while there was significant differences(p≤0.05) on relative weight and length of duodenum, jejunum and in the gastrointestinal tract. There was no any case of mortality recorded between the experimental treatment at all time of study. The results showed a significant increase (p≤0.05) in proactive, economic index and in protein efficiency ratio in all supplemented treatment as compared with control.
