Hematological evaluation and reproductive rejuvination of culled quail (Coturnix japonica)

The study aimed to investigate the effects of forced molting techniques, specifically fasting and low-protein diets, on the hematological parameters and reproductive performance of culled Japanese quail (Coturnix japonica). Five different treatments were tested: fasting, cracked corn, cracked rice, rice bran, and commercial feed. The study focused on assessing feed consumption, body weight changes, egg quality, and hematological parameters before, during, and after the molting process. Results showed significant differences in feed consumption, with quail fed commercial feed consuming the most during both pre- and post-molting stages. In terms of egg weight, quail fed cracked rice and rice bran produced the heaviest eggs, while those subjected to fasting had the lightest eggs. Egg shell thickness did not significantly differ between the treatments, and there was no significant impact on yolk color. The laying percentage post-molt was highest in the fasting group. The proximate analysis revealed differences in the crude protein, fiber, and moisture content of eggs based on the feed type. Despite these differences, all treatments resulted in negative net income due to the low market prices for quail eggs during the study period. The findings suggest that forced molting techniques can affect reproductive performance and egg quality in quail, but cost-effectiveness remains a challenge.
