Abstract

An experiment was conducted to study the effect of feeding ammoniated wheat straw treated with and without HCl on meat quality and various sensory attributes of growing male buffalo (Bubalus bubalis) calves. Due to urea-ammoniation, the CP content of wheat straw increased from 2.90 to 6.96%. The addition of HCl along with urea during urea-ammoniation further increased the CP content to 10.09%. The proximate composition (% fresh basis) of psoas major, longissimus dorsi and semitendinosus were comparable among the groups. However, comparatively higher cumulative muscle mean protein and ash percentage and lower moisture percentage in groups II and III in comparison to group I indicated the desirable effect of feeding AWS and HCl-AWS. The cumulative muscle mean pH in group III (5.54) was comparatively lower than group I (5.65) and II (5.62). The cumulative group mean pH and water holding capacity (% water retained) in semitendinosus was comparatively lower than psoas major and longissimus dorsi. The cumulative muscle mean SSP (g%) was significantly (p<0.05) lower in group III (41.78) than group I (42.45). The cumulative group mean cooking loss (%) was significantly (p<0.01) lower in psoas major (31.61) and longissimus dorsi (29.78) than semitendinosos (35.10). The cumulative group mean SFV (kg/cm 2 ) of psoas major, longissimus dorsi and semitendinosus were 6.38, 6.32 and 6.56, respectively, being lowest in psoas major and highest in semitendinosus. However, the cumulative muscle mean SFV (kg/cm 2 ) in group I, II and III were 6.53, 6.56 and 6.17, respectively, being lowest in group III and highest in group II. The scores of the cooked (2% common salt) buffen for various sensory attributes viz. appearance, flavour, juiciness, texture, mouth coating and overall palatability were comparable among the groups. Results suggested that feeding of ammoniated wheat straw treated with and without HCl to growing male buffalo calves for 180 days had no adverse effect on the meat quality and various sensory attributes.

Highlights

The livestock population in India is the largest (470.86 million) in the world and is estimated to be around 204.58 million cattle, 84.21 million buffaloes, 50.78 million sheep, 115.28 million goats and 12.79 million pigs. (AnnualReport, Govt. of India, 1999-2000)
Results suggested that feeding of ammoniated wheat straw treated with and without HCl to growing male buffalo calves for 180 days had no adverse effect on the meat quality and various sensory attributes
With the present trend of growth, live stock population is estimated to grow at 0.5% in cattle and 1.9% in buffaloes. (Annual Report, Govt. of India 1999-2000), which indicates that the present trend is towards more buffalo production
