Bharti, Sanjay Kumar | Tanwar, V. K. | Anita, | Palod, J.
The effect of vacuum packaging on microbiological quality of roasted chicken. Roasted chicken were subjected to two different type of packaging treatment i.e. aerobic packaging with low density polyethylene bags (con) and vacuum packaging using barrier bags (VP.). Microbiological analyses were done on 0th, 5th, 10th, 15th and 20th day at refrigeration temperature (4±1oC). Studies revealed that microbial counts in terms of total plate count, proteolytic count and yeast and mold count increased significantly (P0.05) with the advancement of storage period and were significantly higher (P0.05) for aerobically packaged product throughout the observation period however, yeast and mould count observed only on 10th, 15th and 20th day of observation period. Lactic acid bacterial counts of vacuum packaged product were significantly higher as compared to aerobically packaged sample.

Afficher plus [+] Moins [-]Influence of thawing temperature on sperm survivability and fertility in buffaloes with frozen semen of Murrah bulls.
2011
Malik, R.K. | Tuli, R.K. | Dipanker, | Singh, Pardeep
The effect of two thawing temperatures (37°Cfor30 sec. and 60°Cfor 7 sec.)on sperm survivability and conception rate in buffaloes with frozen semen of Murrah bulls was compared. Thawing at 60°C resulted in statistically significant increase (P0.05) in sperm survivability (motility,live spermatozoa and intact acrosomes) compared with thawing at 37°c. In all, 161 buffaloes were inseminated with frozen semen thawed at 37°Cand 159buffaloeswith semen thawed at 60°Cbetween 2006-07 and 2009-10. Conception rate of 64.15% and 50.31% was obtained with semen thawed at 60°C and 37°C, respectively, and the difference was significant (P0.05). Artificial insemination of buffaloes with frozen semen thawed at 60°C for 7 sec. could be safely used to improve both sperm survivability and conception rate in buffaloes.
Afficher plus [+] Moins [-]Effect of Strain and Age on Physical Egg Quality and Presence of off-flavour in Duck Eggs.
2009
Mahapatra, C.M. | Beura, C.K. | Sahoo, S.K.
Effect of strain (Khaki Campbell, Indigenous) and age (224 and 280 days) of ducks on the physical egg quality and presence of off-flavour in eggs was studied. The average of egg weight, yolk index and percent yolk weight for the two ages under study were significantly (P0.05) higher in Indigenous duck eggs whereas the same average value for albumen index, Haugh Unit score and percent albumen were higher in Khaki Campbell eggs. However, shape index, yolk colour score, shell thickness and percent shell weight of eggs were comparable for the two strains. Age of ducks had an insignificant influence on shape index, albumen height, shell thickness and yolk index as evident from the least difference between average values of two strains under study. But, the average values of the two strains under study were significantly affected by age for A.I., H.U. score, % albumen weight, % shell weight and % yolk weight. Presence of off-flavour was more pronounced in Khaki Campbell eggs than that of indigenous eggs.
