Growth and Laying Performance of Japanese Quail Fed Graded Levels of Hazelnut Kernel Oil Meal Incorporated into Diets
G. Erener, A. Ozer, N. Ocak
Two experiments were conducted to evaluate the effect of substituting different levels of hazelnut kernel oil meal (HKOM) for dehulled soyabean meal (DSBM) in diets for Japanese quail. Five diets in which HKOM was replaced with 0, 25, 50, 75 and 100% of DSBM protein in a growing diet for a 5 week period using 450 Japanese quails of initial age of 1 week and in a layer diet for a 112 days period using 180 Japanese laying quails of initial age of 7 week were examined in experiments 1 and 2, respectively. Hence, treatment groups were: control (0 HKOM), 0.25 HKOM, 0.50 HKOM, 0.75 HKOM and 1HKOM. In the experiment 1, 1 HKOM decreased BWG compared with the 0 HKOM and 0.25 HKOM, while it increased FCR compared with the 0HKOM at day 21 (p<0.05). Compared with the other groups, 0.75 HKOM and 1 HKOM decreased BWG (p<0.01) at day 28. While the FCR of 1 HKOM was higher (p<0.01) than that of 0 HKOM, 0.25 HKOM and 0.50 HKOM, respectively, that of 0.75 HKOM was higher than that of 0 HKOM and 0.25 HKOM diets at day 28. However, at day 42 of age, BWG, FCR and the feed intake (FI) were not affected (p>0.05) by inclusion of HKOM. Mortality rate, carcase yield and liver, heart and gizzard weight (% of body weight) were not affected (p>0.05) by inclusion of HKOM to the diet. In the experiment 2, egg production was decreased (p<0.05) by the 1 HKOM diet compared with the 0.50 HKOM diet. While FCR increased by the 1 HKOM diet compared with the 0.25 HKOM and 0.50 HKOM diets (p<0.05). Feed intake for quails fed with the 0 HKOM diet was higher (p<0.05) than for quails fed with 0.50 HKOM diet. The egg yolk weight for 0 HKOM diet group was lower (p<0.05) than for quails in 1 HKOM diet group. In conclusion, the results indicate that DSBM can be replaced by HKOM in diets for growing and laying Japanese quails. However 50% HKOM has higher laying performance than 100% HKOM in the laying period.
