Sperm numbers inseminated in dairy cattle and nonreturn rates revisited.
Robert H. Foote,M. Kaproth +1 more
TLDR
The results indicate that, under good conditions, total sperm numbers per straw can be reduced to 10 x 10(6) total sperm with a reduction of nonreturn rates at 59 d, for most bulls, of about 1 percentage unit from the maximum when professional inseminators are use.About:

Sperm transport in the female reproductive tract
Susan S. Suarez,Allan A. Pacey +1 more
TL;DR: Knowledge of the biology of sperm transport can inspire improvements in artificial insemination, IVF, the diagnosis of infertility and the development of contraceptives.

Motility and fertility of bull sperm in whole milk extender containing antioxidants.
TL;DR: Antioxidants generally were not beneficial, except the percentage of motile sperm was improved by 6-11% units when sperm were stored unfrozen or after freezing when 0.5mM of GSH with or without SOD was added, which may have more useful applications in organizations using an egg yolk-based semen extender.

Apparatus, methods and processes for sorting particles and for providing sex-sorted animal sperm
Gary Durack,Jeffrey D. Wallace,Gary P. Vandre,Lon A. Westfall,Jeremy T. Hatcher,Niraj V. Nayak +5 more
TL;DR: In this article, a multi-channel system for classifying particles in a mixture of particles according to one or more characteristics including a common source of electromagnetic radiation for producing a beam of radiation and a beam splitter for producing multiple beams of radiation for each interrogation location associated with each flow channel of the system.
Journal ArticleDOI
Formation of a Reservoir of Sperm in the Oviduct
TL;DR: A bovine seminal plasma protein has been identified that associates with sperm and confers on them the capacity to bind to the carbohydrate moiety in the initial segment of the oviduct.

The effect of optimal and suboptimal concentrations of sperm on the fertility of fresh and frozen bovine semen and a theoretical model to explain the fertility differences
P. Shannon,R. Vishwanath +1 more
TL;DR: There is a suggestion that freezing had no effect on survival time of sperm in the female reproductive tract, but either reduced the probability of fertilisation by a single spermatozoon or altered the pattern of sperm survival in thefemale reproductive tract.

Fertility of Bull Spermatozoa Frozen in Whole Milk Extender with Trehalose, Taurine, or Blood Serum
TL;DR: These additives, useful as cryopreservatives or membrane protectors in other systems, did not enhance the fertility of sperm frozen in whole milk.

Influence of Extender, Extension Rate, and Glycerolating Technique on Fertility of Frozen Bull Semen
TL;DR: In this paper, the fertility was not significantly affected by the addition of glycerol to Tris-fructose-glycerol-yolk extender or when it was added slowly after cooling to 5C.
