The effects of dry heat processing, autoclaving and enzyme supplementation on the nutritive value of wheat for growing Japanese quails

Abstract

Two experiments were conducted to study the effect of autoclaving and heat processing (HP) and enzyme supplementation on wheat nutritive value for quails. In the first experiment, 72 male quails (13 weeks) were used to determine apparent metobalisable energy corrected for nitrogen (AMEn) of wheat samples. In the second experiment, 720 seven-day-old as-hatched Japanese quail were randomly assigned to a 3 )3 factorial design. Factors include three processing methods (untreated, autoclaving and HP) and three levels of enzyme (0, 0.25 and 0.5 g/kg). Each treatment group consisted of 4 replicates of 20 birds. According to the results, the total and insoluble none starch polysaccharides (NSP) and insoluble to soluble NSP ratio increased by processing (PB0.01) and also total and insoluble b-glucan increased by processing (PB0.01). The amount of AME, AMEn, gross energy efficiency and dry matter digestibility of wheat has significantly increased by autoclaving (P B0.05). Quails performance was increased by wheat autoclaving (PB0.05). However, wheat dry heat processing had no significant effect on performance. Adding enzyme to diet significantly improved quails performance. By autoclaving wheat, carcass and breast weight significantly increased (PB0.05). Adding enzyme to diet significantly increased breast and thigh weight (P B0.05). In conclusion, we can use autoclaving, in spite of enzyme supplementation, to improve growth rate and feed conversion ratio of growing quail fed diets based on wheat.

“…Abdominal fat weights and percentages are listed in Table 4. Average abdominal fat weights range from 1.6 to 2.8 g, more significant than the study of Narinc et al (2014) of 1.19 g. The average percentage of abdominal fat ranges from 1.04 to 1.09%; this result follows the study of Kianfar et al (2013)), which ranges from 0.99-1.41%.…”

The effects of dietary bee pollen on lipid peroxidation and fatty acids composition of Japanese quails (Coturnix coturnix japonica) meat under different stocking densities

“…These results were considered to be due to the antioxidative capacity (Eraslan et al 2009) and suitable fatty acids profile of bee pollen (Chen et al 2012). Poultry may be need antioxidant effective dietary supplements or enzymes under stress while they only need to creals-soybean based diets under normal conditions (Tatli Seven et al 2008;Kianfar et al 2013;Makhdum et al 2013). Microclimate conditions around the birds deteriorate when the number of birds per unit of space increases.…”

The microbial pH-stable exogenous multienzyme improved growth performance and intestinal morphology of weaned pigs fed a corn–soybean-based diet

“…Exogenous enzymes have been successfully used in the pigs industry to minimize or eliminate the negative effect of antinutritional factors, to stimulate nutrient digestibility and improve nutritive values of high non-starch polysaccharides (NSP) containing feedstuff such as wheat, oats, barley, and rye (Willamil et al 2012;Kianfar et al 2013;Karimi & Zahedi 2015). However, it is thought that feedstuff like corn and SBM may not benefit from exogenous enzyme supplementation due to lower level of soluble NSP and lesser viscosity (Kim et al 2004;Willamil et al 2012).…”
