| dc.description.abstract | ABSTRACT : An experiment was conducted to study the effect of including graded levels of distillers dried grains with solubles (DDGS) with or without spent brewer’s yeast (SBY) supplementation in the diets of Japanese quails on performance, nutrient digestibility, carcass characteristics, serum parameters and cost economics. The chemical analysis of DDGS and SBY revealed DM, CP, EE, CF, TA, AIA and NFE of 90.49, 30.92, 9.80, 8.52, 6.58, 4.03 and 44.18%; 91.53, 38.80, 1.32, 3.63, 5.61, 0.49 and 50.64%, respectively. The percent Ca and P contents were 0.07, 0.76 in DDGS and 0.10 and 1.46 in SBY, respectively. An experiment was carried out on Japanese quail chicks (675) from day old to 35 days of age under cage system. The Japanese quail chicks were randomly distributed to nine treatments with three replicates, each containing twenty five birds. Iso-caloric and iso-nitrogenous diets were prepared with inclusion of DDGS at graded levels with or without spent brewer’s yeast (SBY) supplementation for grower (0 to 3 weeks) and finisher (3 to 5 weeks) Japanese quail chicks (ICAR, 2013). The experimental diets T2, T4, T6 and T8 contained DDGS at 10, 15, 20 and 25% level, respectively and T3, T5, T7 and T9 diets contained 1% of SBY along with respective levels of DDGS and T1 as control diet. The body weight gain (g) during grower phase was significantly (P<0.01) highest in quails fed diets containing 20% DDGS with SBY (T7) and 20% DDGS without SBY (T6) while it was lowest (P<0.01) in quails fed control (T1) and 10% DDGS without SBY (T2) diets. The body weight gain (g) for entire growth period was significantly (P<0.01) highest in quails maintained on diets containing 20% DDGS with SBY (T7) and lowest body weight gain was seen in quails fed control diet (T1), diet with 10% DDGS without SBY (T2) and 10% DDGS with SBY (T3). The feed intake (g) during grower phase was significantly (P<0.01) highest in quails fed diets containing 20% DDGS without SBY (T6), 20% DDGS with SBY (T7) and 25% DDGS without SBY (T8), while lowest (P<0.01) was recorded in control (T1) diet. The feed intake did not differ significantly among the treatment groups (T1 to T9) during finisher phase. The FCR and mortality of quails showed non-significant differences among the dietary treatments during different growth phases. The digestibility of DM, CP, EE and NFE was not influenced but CF digestibility decreased (P<0.01) during grower and finisher phases. The carcass characteristics, proximate composition of meat and physical properties of meat in terms of meat pH, percent cooking yield, water holding capacity, free fatty acids did not affected significantly with the inclusion of DDGS at graded levels with or without SBY supplementation among the dietary treatments. The serum total protein (g/dl), albumin (g/dl) and globulin (g/dl) levels did not differ significantly, but serum cholesterol (mg/dl) levels decreased significantly (P<0.01) in quails fed experimental diets T1 to T9. The intestinal morphometry i.e. villus height (μm), crypt depth (μm) and villus height/crypt depth ratio in duodenum and ileum showed non-significant differences among the dietary treatment groups. Whereas villus height (μm) and crypt depth (μm) in jejunum was significantly (P<0.01) improved in quails fed diets containing graded levels of DDGS up to 20% with or without SBY supplementation. The cost of feed per bird was significantly (P<0.01) lowest in birds fed diets containing 25% DDGS without SBY (T8) and highest (P<0.01) in quails fed diets containing 20% DDGS with SBY (T7). Based on the results, it is concluded that, dietary incorporation of DDGS up to 25% can be safely included in the quail diets. There is no additional benefit observed with SBY supplementation at 1% level in present study. | en_US |
