Application effects of Antibacterial Peptide in cow’s diet
2014.11.10
1. Experimental objection
This experiment was conducted to see the effects of Antibacterial Peptide on mastitis, milk production and somatic cell count milk production of cow.
2. Product introduction
Main component: Antibacterial Peptide of silkworm generated by gene-engineering bacteria-- bacillus subtilis.
Main function: Improve immunity, kill bacterium and antivirus.
3. Experimental design
Experimental date: 4th June- 5th August, 2014;
Experimental place: one cow pasture of Guangdong Wenshi Company;
Experimental design: Randomly divide 400 cows with same milking period into two treatment: Control Group and Experimental Group (adding 10 g/cow.day Antibacterial Peptide).

4. Feeding management
The management (production management, immune protection, drink and feed process) of cow pasture were same as before.

6. Experimental analysis and discussion
(1) Average milk production increased 1kg/cow.
(2) The incidence rate of mastitis were 6% (Control Group) and 4% (Experimental Group) respectively, it means that Antibacterial Peptide reduced the mastitis incidence by 4%.
7. Conclusion
Addition of Antibacterial Peptide in cow’s feed will significantly increase the milk production, and effectively decrease the incidence rate of mastitis.
