Production Period Of Different Browse Species Suitable For Grazing Small Ruminants, Bidur Paneru, Uma Karki, Shailes Bhattrai, Nevershi Ellis

Professional Agricultural Workers Journal

Abstract

Browse (shrubs, trees, and vines) species are important sources of feed for small ruminants in Alabama and many other states of the U.S. Information on the production period of these species is important to prepare a year-round grazing plan to utilize them well. The objective of the study was to determine the leaf-shedding time of common browse species suitable for small ruminants. This study was conducted at the Atkins Agroforestry and Browse Research and Demonstration Site of Tuskegee University, Alabama. Ten samples of each browse species were tagged, and leaf-yellowing and leaf-fall data collected using photoplots every 14 days …

Swagriculture: A Qualitative Examination Of Women’S Participation In Samoa’S Agriculture Industry As Farmers And Growers, Charlotte Crandall

Independent Study Project (ISP) Collection

This study is an examination of how women participate in agriculture in Samoa as farmers and growers, what hardships women encounter and how they overcome these, and the organizations that influence people’s experiences. Censuses have historically undercounted the number of women in agriculture in developing countries, largely due to rigid international definitions of what counts as labor, which overlook cultural nuances, and this study aims to fill this gap in research. Data was collected through nine Talanoa-inspired interviews with women involved with farming or growing in Samoa, and overarching themes were analyzed. The themes have been grouped by the specific …

Food and Machinery

The volatile flavor compounds in donkey, pig, cattle and sheep leg meat were qualitatively and quantitatively detected by gas electronic nose and gas chromatography-mass spectrometry, and the fatty acid composition was also determined by gas chromatography analyzer. The results of gas-phase electronic nose showed that the flavor difference between the leg meat from donkey and pig was not obvious. However, the significant difference between that from donkey and beef was observed, with 76 volatile substances detected by GC-MS, mainly aldehydes. Aldehydes accounted for 70.71%, 75.36%, 48.76%, 55.94% in donkey, pig, beef and sheep, respectively. The content of n-hexanal with faint …

Remote Sensing Of Ploidy Level In Quaking Aspen (Populus Tremuloides Michx.), Benjamin Blonder, Bente J. Graae, Burke Greer, Marja Haagsma, Kenny Helsen, Rozália E. Kapás, Henry Pai, Jolanta Rieksta, Dillon Sapena, Christopher J. Still, Richard Strimbeck

Aspen Bibliography

1. Ploidy level in plants may influence ecological functioning, demography and response to climate change. However, measuring ploidy level typically requires intensive cell or molecular methods.
2. We map ploidy level variation in quaking aspen, a dominant North American tree species that can be diploid or triploid and that grows in spatially extensive clones. We identify the predictors and spatial scale of ploidy level variation using a combination of genetic and ground‐based and airborne remote sensing methods.
3. We show that ground‐based leaf spectra and airborne canopy spectra can both classify aspen by ploidy level with a precision‐recall harmonic mean of 0.75–0.95 and …

Genetic Variation Of The Dgat1 Gene In Dual-Purpose Dairy Cows And Its Influence On Economically Important Breeding Traits, Mark E. Armitage, Emma Swan, Denise O'Meara

SURE Journal: Science Undergraduate Research Experience Journal

Background
Over the last 10 years, the discovery of individual, or candidate, genes that influence economically important traits has revolutionised how the dairy industry selects cows for breeding programmes. One such gene, the diacylglycerol O-acyltransferase 1 (DGAT1) gene is significant in dairy production as it is associated with the synthesis of fat in milk, and polymorphisms within the gene can be used for selection purposes. In this study, the variants (genotypes) of the K232A polymorphism of the DGAT1 gene, within a dual-purpose dairy herd, bred for both dairy and beef production, were determined, and compared to the Economic …

Biosecurity Council Of Western Australia Annual Report 2018/2019, Biosecurity Council Of Western Australia

Biosecurity published reports

There were four key areas in which the Council focused during the year:

• the attributes required by a biosecurity 'combat' agency to effectively sustain a biosecurity response
• funding for biosecurity research and development in WA
• border biosecurity; and
• WA's preparedness for myrtle rust

Developing constructive advice to Government requires a comprehensive understanding of the needs and challenges of industry, Government and the community. It also requires an understanding of how changes to the biosecurity system might impact these groups and affect WA's biosecurity status.

Memories Of Life On The Farm: Through The Lens Of Pioneer Photographer J. C. Allen, Frederick Whitford, Neal Harmeyer

Purdue University Press Book Previews

John Calvin Allen, professionally known as J. C., worked as a photographer for Purdue University from 1909-1952, and operated his own photography business until his death in 1976. The J. C. Allen photographs represent an historical account of the transition from pioneer practices to scientific methodologies in agriculture and rural communities. During this major transitional period for agriculture, tractors replaced horses, hybrid corn supplanted open-pollinated corn, and soybeans changed from a novelty crop to regular rotation on most farms. During this time, purebred animals with better genetic pedigrees replaced run-of-the-mill livestock, and systematic disease prevention in cattle, swine, and poultry …

Food and Machinery

Forty male C57BL/6 mice aged 4 weeks were selected and randomly divided into 4 groups. Mice in control groups drank normal water, while those in the experimental groups were treated 1.0% α-ketoglutarate acid (group Ⅰ), or 1.8% leucine (group Ⅱ), or 1.8% leucine and 1.0% α-ketoglutarate acid (group Ⅲ) via drinking water. The experimental lasted 35 days. The results showed as follows: ① The growth performance of group Ⅲ was 8.7%, 10.1%, and 10.4% lower than that of the groups control,ⅠandⅡ, respectively； ② Serum albumin in group Ⅲ was significantly higher than that of the groups control,ⅠandⅡ(P<0.05)； ③ The cardiac index of group Ⅲ increased by 19.3%, 13.6%, and 15.2%, respectively, compared with groups control,ⅠandⅡ； ④ The abdominal fat index of group Ⅲ was 24.1%, 10.0%, and 6.7% lower than that of groups control,ⅠandⅡ, the cross-sectional area of the gastrocnemius muscle of group Ⅲ was 46.9%, 20.2%, 27.9% higher than that of groups control,ⅠandⅡ, respectively. In summary, the combination of leucine and α-ketoglutaric acid can reduce the body weight of mice, strengthen the use of fat by organs, and increase the cross-sectional area of gastrocnemius muscle fibers.

Incidence And Prevalence Of Francisella Noatunensis Subsp. Orientalis (Fno) Pathogenic Infections In Feral Hawaiian Tilapia, Daquille Peppers

Biology Theses

Aquaculture has become a major food source for many countries and continues to grow each year. However, many of the fishes that are farmed are susceptible to pathogenic infections such as Francisellosis, a bacterial infection that contributes to disease and high mortality rate in many populations of farmed and wild fish around the world. In 1994, feral and farmed populations of tilapia (e.g. Oreochromis mossambicus) on Oahu, Hawaii were found to be infected with a novel Francisellosis strain, Francisella noatunensis subsp. orientalis (Fno). To prevent the spread of this pathogen, the Hawaii Department of Aquaculture (HDOA) initiated …
