
Trong suốt quá trình học tập rèn luyện tại trường ĐH Nông Nghiệp Hà
Nội cũng như trong quá trình thực tập tốt nghiệp tôi đã nhận được sự giúp đỡ
của thầy cô, bạn bè và gia đình. Đặc biệt trong thời gian làm đề tài tốt nghiệp,
tôi đã được sự giúp đỡ của ban chủ nhiệm và các anh kỹ thuật trang trại Ông
Phạm Tuấn Anh, xã Ngũ Phúc, huyện Kiến Thụy, thành phố Hải Phòng.
Tôi xin bày tỏ lòng biết ơn sâu sắc đến các thầy cô giáo trong trường nói
chung, cũng như các thầy cô trong khoa Thú Y nói riêng đã chỉ bảo tận tình,
giúp đỡ tôi trong suốt 5 năm học vừa qua.
Đặc biệt tôi cũng xin bày tỏ lòng biết ơn tới TS.Lê Văn Phan, giảng viên
bộ môn Vi sinh vật – Truyền nhiễm, khoa Thú y - Trường Đại học Nông nghiệp
Hà Nội đã dành nhiều thời gian tận tình hướng dẫn tôi trong suốt quá trình học
tập và thực hiện đề tài.
Nhân dịp này tôi xin gửi lời cảm ơn chân thành tới gia đình, bạn bè và tất
cả mọi người đã luôn dành cho tôi sự quan tâm và giúp đỡ.
Cuối cùng, tôi xin kính chúc tập thể các Thầy Cô giáo trong khoa Thú Y
cùng gia đình và bạn bè luôn luôn mạnh khỏe và công tác tốt. Luôn là những
người lái đò cần mẫn đưa sinh viên đến những bến bờ tri thức.
Hà Nội , ngày 30 tháng 11 năm 2013
