Effect of different energy and protein levels on the egg production of rural poultry
2003
Rehman, A. | Bhatti, B.M. (Poultry Research Inst., Rawalpindi (Pakistan))
A study was conducted to determine the effect of different nutrients i.e. metabolizable energy (ME) and crude protein (CP) content of ration on the egg production and egg weight of rural layers. For the purpose six different experimental rations containing 2700, 2900 kcal/kg ME and 14, 16, 18 percent CP were offered to the birds. The results indicated that egg number increased with proportional adversely affected as the CP of the ration was increased weight of the layers was proportionally increased with ration at constant ME level, while increase in ME level egg weight. increase in ME, while it was at constant ME level. The egg increase in CP content of the did not significantly affect the egg weight.

2009
Sreedhar, S. | Suresh Babu, D.
The study found out the chemical and microbial quality of various milk samples collected from different sources of milk procured from rural areas of Tirupati. Thefat, SNF and protein percentages of milk samples collected from Dairy Experimental Station were higher than the other milk samples collected from commercial dairies of Sangam, Balaji and Heritage and local vendors. The milk samples collected from local vendors showed lower fat, SNF and protein percentages. No significant difference was observed in the milk samples collected from commercial dairies of Sangam, Balaji and Heritage with regard to fat, SNF and protein percentages. None of the milk samples collected from Dairy Experimental Station were found to be adulterated with water, whereas higher percentage of water was observed in the milk samples of local vendors. The Standard Plate Count of milk from local vendors is higher followed by Dairy Experimental Station. Presence of E.coli organisms in the milk samples collected from local vendors and Dairy Experimental Station indicated the extraneous contamination and unhygienic conditions of milking barn.
