Evaluation Of Antral Follicle Count And Ovarian Morphology In Crossbred Beef Cows: Investigation Of Influence Of Stage Of The Estrous Cycle, Age, And Birth Weight, R. A. Cushman, M. F. Allan, Larry A. Kuehn, W. M. Snelling, Andrea S. Cupp, H. C. Freetly Jan 2009

Evaluation Of Antral Follicle Count And Ovarian Morphology In Crossbred Beef Cows: Investigation Of Influence Of Stage Of The Estrous Cycle, Age, And Birth Weight, R. A. Cushman, M. F. Allan, Larry A. Kuehn, W. M. Snelling, Andrea S. Cupp, H. C. Freetly

Department of Animal Science: Faculty Publications

Depletion of the ovarian reserve is associated with reproductive senescence in mammalian females, and there is a positive relationship between the size of the ovarian reserve and the number of antral follicles on the surface of the ovary. Therefore, we conducted a series of experiments to investigate the influence of stage of the estrous cycle, age, and birth weight on antral follicle counts (AFC) in beef cows and heifers. Pairs of ovaries were collected from crossbred beef cows at slaughter (n = 72) or at necropsy (n = 333; 0 to 11 yr of age); all visible antral follicles were …

Fertility Of Semen Used In Commercial Production And The Impact Of Sperm Numbers And Bacterial Counts, D. L. Reicks, Donald G. Levis Nov 2008

Fertility Of Semen Used In Commercial Production And The Impact Of Sperm Numbers And Bacterial Counts, D. L. Reicks, Donald G. Levis

Department of Animal Science: Faculty Publications

The objective was to monitor sperm counts and bacterial presence on randomly pooled semen doses over 3 years and to determine effects on the farrowing rate and total born in two large farm systems, each serviced by its own boar stud. Sperm counts were divided into increments of 0.5 × 109 for data analysis. There was no effect of sperm count or the presence of bacteria on farrowing rate (n = 9502 observations). Furthermore, based on 7311 observations, there was no effect of the mere presence of bacteria on total born, but sperm count had a significant effect …


Utilization Of Soybeans Or Corn Milling By-Products In Beef Heifer Development Diets, H. L. Harris, Andrea S. Cupp, A. J. Roberts, Richard N. Funston Jan 2008

Utilization Of Soybeans Or Corn Milling By-Products In Beef Heifer Development Diets, H. L. Harris, Andrea S. Cupp, A. J. Roberts, Richard N. Funston

Department of Animal Science: Faculty Publications

Whole raw soybeans (SB), wet corn gluten feed (WCGF), and corn dried distillers grains (DDG) are sources of protein in heifer development rations. The objectives of this study were to compare puberty status before synchronization of estrus, response to synchronization, and AI and final pregnancy rates in heifers developed on diets containing SB, WCGF, or DDG that were formulated to be similar in energy and CP. These ingredients vary substantially in fat content, which may affect reproductive performance. Rate of gain during the feeding period and post-AI performance were also compared. In a preliminary experiment, 104 crossbred heifers were fed …


Reproductive Health Of The Florida Flock Of Introduced Whooping Cranes, Marilyn G. Spalding, Martin J. Folk, Stephen A. Nesbitt Jan 2008

Reproductive Health Of The Florida Flock Of Introduced Whooping Cranes, Marilyn G. Spalding, Martin J. Folk, Stephen A. Nesbitt

Proceedings of the North American Crane Workshop

We examined the reproductive parameters of the introduced non-migratory flock of whooping cranes in Florida. Of 289 cranes introduced, 67 males and 65 females survived at least 3 years. The first behavioral pairs appeared in 1995, and eggs were first laid in 1999. In total, eggs were laid in 47 nests, 17 chicks hatched, and 4 young fledged by 2005. Severe drought conditions through 2001 were thought to be the reason for low reproductive nest success. In 2003 nesting conditions improved and 71% of nests with eggs, hatched chicks. During the next 2 years, with continued wet conditions, the proportion …

Sex Differences In The Onset Of Seasonal Reproductive Quiescence In Hamsters, Annaliese K. Beery, Justin J. Trumbull, Jyeming M. Tsao, Ruth M. Costantini, Irving Zucker

Neuroscience: Faculty Publications

Day length is the primary cue used by many mammals to restrict reproduction to favourable spring and summer months, but it is unknown for any mammal whether the seasonal loss of fertility begins at the same time and occurs at the same rate in females and males; nor it established whether the termination of mating behaviour in males and females coincides with the loss of fertility. We speculated that females, owing to their greater energetic investment in reproduction, are the limiting sex in terminating offspring production in short days (SDs). Oestrous cycles and production of young were monitored in Syrian …


Effect Of Fenbendazole On Turkey Semen Quality, M. R. Bakst, M. Kramer, J. Long Jan 2006

Effect Of Fenbendazole On Turkey Semen Quality, M. R. Bakst, M. Kramer, J. Long

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

Fenbendazole (FBZ) is an anthelmintic recently approved to treat and control nematode infections in growing turkeys. When administered to growing turkeys there are no detrimental side effects. However, when we used FBZ to treat nematodes in mature breeder toms, we observed a decrease in semen quality and a subsequent precipitous decline in fertility to less than 20% within 6 wk of administration. An experiment was designed to determine the impact of FBZ administration on aspects of spermatogenesis and semen quality. We discovered that although sperm viability and concentration was not significantly affected by FBZ, this drug significantly reduced sperm mobility. …

G05-1582 How To Reduce Heat Stress In Dairy Cattle, Jeffrey F. Keown, Paul J. Kononoff, Richard J. Grant Jan 2005

G05-1582 How To Reduce Heat Stress In Dairy Cattle, Jeffrey F. Keown, Paul J. Kononoff, Richard J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

Four ways to reduce heat stress and maintain production and fertility in dairy cattle.

Heat stress is one of the leading causes of decreased production and fertility in Nebrasks dairy cattle during summer months. These losses are apparent in the decreased amount of milk shipped, increased days open and decreased breedings per conception. Some heat stress is unavoidable, but effects can be minimized if certain management practices are followed.

Phenotypic Traits As Reliable Indicators Of Fertility In Male Broiler Breeders, S. Mcgary, I. Estevez, M. R. Bakst, D. L. Pollock Jan 2002

Phenotypic Traits As Reliable Indicators Of Fertility In Male Broiler Breeders, S. Mcgary, I. Estevez, M. R. Bakst, D. L. Pollock

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

Genetic selection procedures applied to improve broiler performance may negatively impact the subsequent reproductive efficiency of breeders, particularly in males. Identification of traits that reliably indicate individual male fertility would facilitate selection for reproduction. We hypothesized that physical traits, such as comb area, relative testicular weight, and testicular weight asymmetry, may correlate with fertility in two male-selected primary broiler breeder strains (A and B). Thirty males per strain, individually housed with an average of 10 females, were evaluated at five age periods within the 30-to-50-wk breeding cycle. Flock fertility by candling eggs at Day 19 of incubation and sample fertility …


Reproduction And Food Habits Of The Lined Seahorse, Hippocampus Erectus (Teleostei: Syngnathidae) Of Chesapeake Bay, Virginia., R. L. Teixeira, John A. Musick Feb 2001

Reproduction And Food Habits Of The Lined Seahorse, Hippocampus Erectus (Teleostei: Syngnathidae) Of Chesapeake Bay, Virginia., R. L. Teixeira, John A. Musick

VIMS Articles

The reproductive and feeding biology of the lined seahorse, Hippocampus erectus, was studied inChesapeake Bay. Seahorses are monogamous, and males incubate the eggs received from femalesin a closed brood pouch (= marsupium). Females do not play any parental care after mating. Totalsex ratio and the operational sex ratio was strongly skewed toward females. Males and females hadsimilar number of eggs/embryos and hydrated oocytes, respectively. The number of eggs/embryosfound in the male brood pouch varied from 97 to 1,552 (fish from 80 to 126 mm TL), whereas thenumber of hydrated oocytes in female varied from 90 to 1,313 (fish from 60 …

The Effects Of Semen Collection On Fertility In Captive, Naturally Fertile, Sandhill Cranes, Guojun Chen, George F. Gee, Jane M. Nicolich, Joanna A. Taylor

Proceedings of the North American Crane Workshop

We tested to see if semen collection interferes with fertility in naturally fertile pairs of cranes. We used 12 naturally fertile, Florida sandhill crane (Grus canadensis pratensis) pairs for this study, 6 control and 6 experimental. All pairs had previously produced fertile eggs. Semen was collected on Tuesday mornings and Friday afternoons from 26 February 1993 to 4 June 1993. We used standard artificial insemination methods to collect and to evaluate the semen and spermatozoa. Semen collection had minimal effect on semen quality and semen quantity. Semen volume, sperm density, sperm motility, sperm morphology, sperm viability, sperm number …

Paternity Efficiency In Turkeys Differes Extensively After Hererospermic Insemination, Ann M. Donoghue, Murray R. Bakst, Paul Drummond, Shakura Haqque, Edward J. Smith, Daniel J. Donoghue Jan 1999

Paternity Efficiency In Turkeys Differes Extensively After Hererospermic Insemination, Ann M. Donoghue, Murray R. Bakst, Paul Drummond, Shakura Haqque, Edward J. Smith, Daniel J. Donoghue

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

All commercial turkey hens in the U.S. are bred by artificial insemination (AI). Since semen samples are pooled from 10 or more males (heterospermic inseminations), paternity of the progeny is rarely known. Whereas it is known that sperm competition exists, the degree to which any male's sperm fertilizes ova relative to other male's remains unknown. In this work, we determined individual male fecundity relative to that of other males in the study and attempted to establish a relationship between male fecundity and semen characteristics in turkeys. Fingerprinting of genomic DNA from parents and offspring was used to determine parentage efficiency. …

Ec98-151 Amaranth: Production Manual For The Central United States, Jane Sooby, David D. Baltensperger, Robert Myers, David Brenner, Richard Wilson, Charles Block

University of Nebraska-Lincoln Extension: Historical Materials

Amaranth is a small-seeded grain crop with a dramatic history. Once a staple in the diet of the Aztec Indians, today it is grown throughout the world. In the United States much of the production is small-scale and organic, grown mainly for the natural and health food markets. There also has been steady use of the crop for breakfast cereals, snack foods, and mass-produced multigrain bread products. Amaranth is a broadleaf plant well-adapted to a range of arid and humid environments. As a crop it fits into many dryland rotations, performing well following wheat, proso millet, or other grain crops. …

Effects On White Leghorn Hens Of Constant Exposure To Ultraviolet Light From Insect Traps, Jerome Hogsette, Henry Wilson, Susan Semple-Rowland

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

Constant exposure of Hy-Line® W-36 White Leghorn hens to ultraviolet light from insect traps resulted in no significant differences in egg production, fertility, hatchability of fertile eggs, or total hatchability. Also, there were no apparent effects on the eyes of the birds. Results were the same when either blacklight or blacklight blue tubes were used. The need for additional testing of light traps for nuisance fly control in commercial caged layer houses is discussed.

Department of Animal Science: Faculty Publications

Effects of environmental factors such as ewe age, season of exposure, and time from lambing to exposure on fertility were evaluated using records on 1,084 Dorset ewes in the STAR accelerated lambing system. The STAR program consisted of five 30-d concurrent breeding and lambing periods per year beginning on January 1, March 15, May 27, August 8, and October 20. Fertility in the flock changed in a cyclic and predictable fashion during the year. Changes in prolificacy were less consistent but also tended to show cyclic variation. Matings that occurred within the typical breeding season (August, October, and January) were …
