متن کاملQuantification and comparison of TLR2 activity in monocyte-derived macrophages of zebu and crossbred cattle
The present study was conducted to quantify and compare TLR2 (toll-like receptor 2) activity in monocyte-derived macrophages of zebu (Tharparkar) and crossbred (Holstein-Friesian × Jersey × Brown Swiss × Hariana) cattle. The cells were either induced with Pam3CSK4 or kept as control. The TLR2 activity was quantified in terms of IκB-α inhibitory subunit (NFKBIA) messenger RNA (mRNA) copies...
متن کاملPreweaning growth rate and weaning traits of Angus, zebu and zebu-cross cattle.
A 4-yr study was conducted on the preweaning growth rate and weaning traits of 620 calves from: (1) Angus (A), Brahman (B), Brangus (BR) and Africander-Angus (AF) dams sired by A and B bulls; (2) BR dams mated to BR sires and (3) AF dams mated to AF sires. Heifers were placed in the breeding pastures as 2-yr-olds and exposed to bulls for 75 d. Breed groups differed (P less than .01) in weaning ...
متن کاملProtein Requirements of Zebu Beef Cattle
Protein is one of the most important essential nutrients; it is involved in many vital functions in the body, such as growth and tissue repair, enzyme catalysis, transport and storage, coordinated movement, mechanical support, immunological protection, generation and transmission of nerve impulses, and control of metabolism, growth and cellular differentiation.
