Quail egg production has experienced a steep rise in the last decade. Nutrition is the main factor affecting productive potential in the poultry industry, as appropriate nutritional management is necessary to ensure the maintenance of optimal physical conditions, growth and the production of high quality products. Meat and bone meal (MBM) has often been used in the poultry industry as an alternative and cost-effective source of protein in partial replacement of corn and soybean meal. However, there have been no studies to date that have investigated the effect of dietary MBM on the performance of quail or on the costs of production in the starter phase. This is particularly important considering that this phase is characterized by large investments by producers, without immediate economic return. In this study, we investigated whether partial replacement of soybean meal (SBM) by meat and bone meal (MBM) in the diet of Japanese quail during the starter phase is a viable alternative that would maintain or improve their productive and economic performance. Our results show that the inclusion of MBM in the diet of quail reduces feeding costs by up to 6% without impairing productive performance.

In a factorial experiment, crossbred pullets reared on a low plane of nutrition, based on a dietary regime of either all-mash or mash plus whole grain, were given laying diets, supplemented with ground limestone and cockle shell grit as alternative calcium supplements, and Australian soybean meal and meat and bone meal as alternative protein supplements, from 18 to 72 weeks of age. From 48 weeks of age the laying diets were fed with or without 600 p.p.m. EDTA. The effects of these treatments on shell quality, egg production, feed conversion and liveweight were examined. Pullets reared on the mash plus whole grain regime wereheavier at housing time, matured earlier, laid eggs with better shells and tended to perform more efficiently than the lighter pullets reared on an all-mash regime. Supplementation of the laying diet with cockle shell grit improved shell quality. This improvement was significant only for the first half of the laying cycle which occurred during the warmer part of the year. Calcium supplements had no effect on other traits studied. inclusion of Australian soybean meal in the laying diet resulted in better shell quality right through the laying year and rate of lay, egg weight and efficiency of feed conversion was significantly better than that of birds given diets based on meat and bone meal. The addition of 600 p.p.m. EDTA to the laying diet at 48 weeks of age had adverse effects on shell quality but egg production was not significantly affected.

Digestive enzymes activity influence feed utilization by fish, and its understanding is important to optimize diet formulation. This study reports the digestive enzyme activities of jundiá juveniles fed diets with protein sources. Fish were fed six experimental diets for 90 days: MBY (meat and bone meal + sugar cane yeast), SY (soybean meal + sugar cane yeast), S (soybean meal), MBS (meat and bone meal + soybean meal), FY (fish meal + sugar cane yeast) and FS (fish meal + soybean meal), and then sampled every 30 days and assayed in two intestine sections for digestive enzymes - trypsin, chymotrypsin and amylase - activities; gastric protease was assayed in the stomach. Digestive and hepatosomatic index, intestinal quotient, digestive tract length and weight gain were also measured. Trypsin and chymotrypsin activities were higher (p < 0.0001) in fish fed diets containing animal protein sources (MBY, MBS, FY and FS diets). Alkaline proteases were negatively affected by dietary soybean meal in the SY and S diets. Amylase activity had greater variation between diets and intestine sections. Fish fed MBY and MBS diets showed higher gastric protease activity (p < 0.0001). Weight gains were higher in fish fed the MBS and FS diets (p < 0.05). Highest values (p < 0.05) of digestive tract length were observed in fish fed MBS and FY diets, but no correlation with enzymes activities was found. Hepatosomatic index (HSI) was affected by diet composition. Dietary composition influenced digestive enzymes activities of jundiá.
