ABSTRACT
A study was conducted to evaluate the effects of dietary inclusion of synbiotics (mannan-oligosaccharides-MOS & probiotics- Bacillus subtilis and Bacillus amyloliquefaciens) at different energy and protein level on performance of egg-type chicks during hot-dry summer (April-May, Temperature - 28.0 ± 0.120C to 35.25 ± 0.370C, RH, %: 68.95±0.90 to 79.15±0.61). After feeding a standard diet from 0-21 days of age, the chicks were randomly distributed into four dietary treatment groups viz., T1 with high energy 2800 kcal ME/kg and high protein 18% (HEHP), T2 with HEHP diet with synbiotics (MOS @ 0.2% + probiotics premix Protimix @ 0.025 %), T3 with low energy 2700 kcal ME/kg low protein 17.34% (LELP) and T4 with LELP diet with synbiotics (MOS @0.2% + probiotics premix Protimix @0.025 %). Each treatment was fed to fifty birds divided in five replicates of ten each from 22-63 days of age. Feed intake and body weight changes were recorded at weekly interval. The yield of immune organs, blood biochemical profile and intestinal histomorphometry were measured at 42nd and 63rd day post-hatch. Feed intake and feed conversion ratio (feed; gain FCR) improved (P<0.05) in HEHP+ synbiotics group. H:L ratio reduced (P<0.05) in synbiotics fed group. The relative yields of immune organs like thymus, spleen & bursa were significantly (P<0.05) higher in synbiotics supplemented groups. Total protein (P<0.001), SGOT (P<0.001), SGPT (P<0.001), creatinine were significantly (P<0.05) improved, while cholesterol, uric acid & ALP values were significantly (P<0.001) reduced in birds fed synbiotics supplemented diets. Villus height & crypt depth improved significantly (P<0.001) in synbiotics supplemented group. Thus it was concluded that high energy (2800 kcal ME/kg) and high protein (18% CP) diet along with inclusion of synbiotics was beneficial for egg type starting chicks during dry summer.
