Experiments were conducted to determine the nutritional value of cochineal waste produced by San-Ei Gen F.F.I. Inc., Okayama Factory, Maniwa City, Okayama Prefecture as a replacement for fish meal. In the first trial, the nutritional contents of cochineal waste and cochineal waste feed produced by substituting fish meal with cochineal waste were measured. In the second trial, the cochineal waste feed was given to female quail chicks aged 6 weeks, and its effects on the subsequent growth and production performance were evaluated. The nutritional value of cochineal waste was 66.4% crude protein, 10.5% crude fat, and 3.9% crude ash. The crude protein content of cochineal waste was slightly higher than that of fish meal. However, the crude ash content was very low, and the Ca, P, K, Na, and Mg contents were markedly low in cochineal waste. The Ca and P contents of the cochineal waste feed were lower than those of the fish meal feed, whereas the amino acid contents in cochineal waste feed were comparable with those of fish meal. The egg weight, feed consumption, and body weight of the chicks fed cochineal waste (100% replacement of fish meal) were inferior to those of the control (fish meal content) from 6 to 29 weeks of age. However, no significant differences in egg production, egg weight (except at 28 weeks of age), feed consumption, feed conversion, and body weight were observed between the control and chicks fed cochineal waste (50% replacement of fish meal). The results revealed that the half of the fish meal can be replaced by cochineal waste during the laying period in Japanese quail.
