Butterhead Lettuce Variety Performance Trial In A Hydroponic Nft System, Leah Worth, Mary Rogers, Amanda Reardon

Midwest Vegetable Trial Reports

Lettuce (Lactuca sativa L.) is a cool-season crop grown exclusively for fresh consumption. The intensive consumer demand of pre-packaged and living butterheads in the market today has been supported by the shift of soil production methods to soilless hydroponic systems. Hydroponic varietal and fertility recommendations for living butterhead optimization are limited to small-scale growers, however. To increase understanding of butterhead lettuce fertility preference, we examined two different water reservoir fertility concentrations across 12 replicated nutrient film technique (NFT) systems planted with six butterhead lettuce varieties. No differences were found between varieties grown in either recommended or high fertility concentrations, …

Does Biochar Improve All Soil Ecosystem Services?, Humberto Blanco-Canqui

Department of Agronomy and Horticulture: Faculty Publications

Biochar is considered to sequester C and deliver other soil ecosystem services, but an overview that synthesizes the current knowledge of biochar implications on all essential soil ecosystem services is difficult to find in the ample biochar literature. Most previous research and review articles on this topic focused on a single ecosystem service and did not integrate all essential soil ecosystem services. This overview paper (1) synthesizes the impacts of biochar on water and wind erosion, C sequestration, soil water, nutrient leaching, soil fertility, crop yields, and other soil ecosystem services based on published literature and (2) highlights remaining research …

Heifer Calving Date Positively Influences Calf Weaning Weights Through Six Parturitions, R. A. Cushman, L. K. Kill, Richard N. Funston, E. M. Mousel, G.A. Perry

West Central Research and Extension Center, North Platte

Longevity and lifetime productivity are important factors influencing profitability for the cowcalf producer. Heifers that conceive earlier in the breeding season will calve earlier in the calving season and have a longer interval to rebreeding. Calves born earlier in the calving season will also be older and heavier at weaning. Longevity data were collected on 2,195 heifers from producers in South Dakota Integrated Resource Management groups. Longevity and weaning weight data were collected on 16,549 individual heifers at the U.S. Meat Animal Research Center (USMARC). Data were limited to heifers that conceived during their first breeding season. Heifers were grouped …

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. …

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 …

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. …

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.

Future Developments In Artificial Insemination Technology, Murray R. Bakst

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

The development of artificial insemination (AI) technology over the past decade has resulted in some significant advances in poultry breeding. However, because there are few poultry scientists performing fundamental research to advance AI technology, alternative approaches must be examined in an effort to expand AI technology. This paper suggests that the technology available for cell and tissue culture propagation should be evaluated and the applicability of this technology to poultry AI technology assessed. Instrumentation and clinical testing procedures used for the evaluation of somatic cells in culture could provide objective data before and after semen storage on large numbers of …

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 …
