The Effects of Dietary Phosphorus on the Growth Performance and Phosphorus Excretion of Dairy Heifers
Heifers Growth Performance Phosphorus Phosphorus Excretion
2016/7/27
The objective of this study was to investigate the effects of reducing dietary phosphorus (P) on the frame size, udder traits, blood parameters and nutrient digestibility coefficient in 8- to 10-month...
Ovarian Follicular Dynamics, Ovarian Follicular Growth, Oocyte Yield, In vitro Embryo Production and Repeated Oocyte Pick Up in Thai Native Heifers Undergoing Superstimulation
FSH Follicle OPU COCs IVP Cattle
2016/5/11
The objective of this study was to compare the effectiveness of the protocols for superstimulation of follicular growth in Thai native heifers. Heifers (n = 20) were randomly divided into four groups ...
