Effect Of Egg Weight On Chick Weight And On Subsequent Performance Of Japanese Quails - 1989
The present project was planned to study the effect of egg weight on chick weight at day old and its subsequent performance in Japanese quails.
Three hundred and sixty quail eggs were purchased from a local breeding farm and divided into 3 equal groups i.e., A, B and C according to their weights i.e. , small (8.5-9.5 gm), medium (9.6-10.5 gm) and large (10.6-11.5 gm) respectively. The eggs were incubated and hatched.
Sixty chicks from each group were randomly divided into 3 replicates of 20 chicks each and were reared under the identical management and environmental conditions. A commercial quail's ration was provided ad libtium. Fresh and clean water was given all the times.
The experimental chicks were weighed individually at one day-old and on weekly basis upto the age of 6 weeks. Weekly feed consumption was also recorded for each group. At 6 weeks of age two birds from each replicate were picked up randomly and slaughtered to observe the dressing percentage of visceral organs and biochemical values of blood. The average weight gain observed per quail upto 6 weeks of age on the basis of egg weight in groups A, B and C was 119.70, 130.70 and 147.30 gms and the average feed consumption per quail was 472.83, 481.89 and 463.88 gms respectively. The feed efficiency values were 3.95, 3.68 and 3.14 respectively. The mortality percentage was 5.00, 3.33 and 0 percent.
The average dressing percentage was 60.64, 67.88 and 64.23 respectively. The average weight of liver was apparently more in quails hatched from group B as compared to quails hatched from group A and C. The quails hatched from group B exhibited apparently maximum weight of heart as compared to quails hatched from group A and C. However, the average weight of gizzard was maximum in quails hatched from group C as compared to quails hatched from group A and B.
Statistical analysis of the data revealed non-significant effect of egg weight on feed consumption, dressing percentage, giblet weight (liver, heart and gizzard), protein, lipids and cholesterol of serum, packed cell volume, total leucocytic count, erythrocyte sedimentation rate, hemoglobin and erythrocytes. However, the effect of egg size was highly significant at (P 0.1) in case of body weight gain, feed efficiency and blood sugar level of experimental quails. The monetary return per quail was Rs. 2.00.
