Duration Of Fertility Of Turkeys Inseminated At Different Times After The Onset Of Photostimulation, M. R. Bakst

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

To investigate the relationship between photostimulation, ovary and oviduct weights, and oviducal sperm-storage tubule (SST) development and functional capacity, 33-week-old turkey hens were placed in four groups of 15 hens each. Each group was inseminated three times in 30 min with 50 × 10⁶ spermatozoa (a total of 150 × 10⁶ spermatozoa) on the day of photostimulation, or on Days 7, 14, or 21 after the onset of photostimulation (Groups A, B, C and D, respectively). From weeks 4 to 8 after photostimulation, 5 additional hens were inseminated each week and then killed 24 h later to determine …
