Performance of Japanese Quails (Coturnix coturnix japonica Temminck & Schlegel, 1849) Fed Hatchery Waste Meal

Abstract

This study aimed to evaluate the effect of hatchery waste meal in ration on performance of quails. The experiment used 500 quails (Coturnix coturnix japonica Temminck & Schlegel, 1849) aged 30 d with an average initial body weight of 94.75 g ± 4.17 g. The quails were randomly allocated to five dietary treatments in a completely randomized design with five replicates containing twenty quails. The dietary treatments were: P0 = basal ration; P1 = 96 % basal ration + 4 % whole hatchery waste meal; P2 = 92 % basal ration + 8 % whole hatchery waste meal, P3 = 96 % basal ration + 4 % shells hatchery waste meal, P4 = 92 % basal ration + 8 % shells hatchery waste meal. The dietary treatments were given for 28 d. Performance data were analyzed by using analysis of variance, and when the treatment indicated significant effects, it was continued with orthogonal contrast test. Feeding hatchery waste meal improved the performance of quails (P < 0.05). Shells hatchery waste meal improved egg production, feed conversion, and protein efficiency ratio than whole hatchery waste meal (P < 0.05). Feeding 8 % whole hatchery waste meal improved egg production than 4 % whole hatchery waste meal (P < 0.05), while feeding 8 % shells hatchery waste meal tended to improve egg production than 4 % shells hatchery waste meal (P = 0.09). It can be concluded that hatchery waste meal improved the performance of quails, particularly 8 % shells hatchery waste meal, which showed the best response.

Response of Laying Quail to a Diet Enriched with Cocoa Pods Fermented by Pleurotus ostreatus.

“…The decrease in hen-day egg production and egg mass in treatment E was caused by feed consumption, which also decreased in treatment E. Low feed consumption showed that less food was digested and absorbed for production. Indreswari (2016) states that egg production is determined by feed consumption. High crude fiber content in treatment E also results in decreased henday egg production.…”

“…Another advantage of fermentation with Pleorotus ostreatus is the presence of lovastatin compounds that can inhibit the formation of cholesterol. The mechanism of action of lovastatin can inhibit the action of the HMG-CoA reductase enzyme which acts to synthesize mevalonate (mevalonate is needed for cholesterol synthesis) such that cholesterol production is reduced (Haslinger-Loffler, 2008).…”

Metagenomic analysis of non-pathogenic and pathogenic cecal bacteria profiles in quail supplemented with betaine

“…Feed manipulation is the cheapest and most efficient strategy to lower heat stress negatively affecting poultry [16]. Feed supplementation is a feed manipulation method widely used in poultry and can provide significant results on production performances [17][18][19][20][21]. According to Metzler-Zebeli et al [3], betaine is vital in reducing heat stress negatively effect.…”
