Proceedings of the Twenty-Ninth Vertebrate Pest Conference (2020)
A non-toxic liquid fertility control bait for rats has recently become commercially available (ContraPest® from SenesTech, Inc.). This product contains two chemicals, both of which impair spermatogenesis in male and reduce ovulations in female rats. We tested the efficacy of this bait in wild-caught adult black rats from the island of Hawai’i in a short-term laboratory trial. A control group (n = 25) was offered placebo bait and the treatment group (n = 25) was offered fertility control bait, both ad libitum, during a 15-day introduction period and during the first of four breeding rounds, for a total of 58 …

A subpopulation of cows in the Physiology herd has been identified as subfertile due to sporadic or chronic anovulation. This decrease in fertility could be lost profits for farmers and raises questions about ovulation disorders in women. Granulosa cells, a type of cell that is essential to ovarian follicle development, was investigated to determine if high concentrations of a hormone, androstenedione, could impact the follicular environment enough to cause anovulation disorders. Previous studies suggested that excess androgen may decrease the number of functioning granulosa cells by preventing them from proliferating within the follicle. Fewer granulosa cells mean fewer cells that …

Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This publication is a revision of North Central Regional Publication 120, published by the Nebraska Agricultural Experiment Station (Research Bulletin 196) in July, 1961. It summarizes the more important results from this project during its first 19 years of operation. It is by no means complete and includes only what is considered to be the "highlights" of findings at this time. A bibliography of all publications that provided the basis for this summary statement is included. This publication is in the nature of a progress report on many aspects of beef cattle breeding research. Although it is based on considerably …
