PSV-18 - Effects of oats fodder and quantitative feed restriction on egg and meat quality of native Bangladeshi geese

Abstract: The present study was designed to assess the efficacy of Oats (Avena sativa) fodder as a supplementation along with concentrate feed for determining egg quality, meat color and texture, pH, drip loss, cooking loss, and water holding capacity (WHC) of Bangladeshi White and Gray geese varieties. A total of 60 adult geese from White and Grey varieties were reared in a semi-intensive production system in Bangladesh Livestock Research Institute, Savar. After 3 months of rearing, we collected freshly laid eggs for 4 weeks and 20 eggs /bird and 480 eggs for egg quality analysis. After that, those birds were slaughtered for meat quality analysis at 38 weeks of age. They were randomly divided into 4 groups with 3 replicates having 5 geese in each replication. Maize soya-based diet was considered as Basal diet and marked as T₀- 200g concentrated feed, T₁= 180 g Basal diet+ 138 g oats fodder, T₂= 160 g Basal diet+ 276 g oats fodder, T₃= 140 g Basal diet + 415 gm oats fodder daily. Egg quality was determined through the egg tester analyzer ultimate machine. A calibrated waterproof pH meter equipped with a spear tip probe was used to measure the pH values of the breast and thigh meat 24 hours of slaughter. Meat color was determined in triplicate using a Chromo meter CR-8, (3nh, China) and texture were determined using a texture analyzer (Tx-700, France). The data were statistically analyzed using SPSS software (23 version). Treatment had a remarkable effect on Albumen index, yolk CP % and breast meat cohesiveness value (p < .05). For egg quality parameter result showed that those traits were not significantly varied but tended to be higher in T₂ group. Yolk and albumen CP% for T₂ group was higher than other groups, but Breast meat cohesiveness tended to be lower in that group. However T₂ group showed lower drip loss and cooking loss, higher WHC and also higher a* (redness) value but these parameters were not significantly affected by treatments. Supplementation of native Bangladeshi adult geese with 160 g concentrate feed+ 276 g oats fodder daily was found to be beneficial for improving egg and meat quality.
