Negative Impacts Of The Beef Industry: Lab-Grown Meat, Stephanie Grass

WRIT: Journal of First-Year Writing

The beef industry is harmful to the environment and human health and alternative solutions must be implemented in order to mitigate the effects of climate change. Water and grain are used in agriculture in abundance despite the negative environmental effects it causes. Cattle are the biggest contributors to greenhouse gas emissions in the sector, also contributing to climate change. Antibiotics are used in large quantities without regard to potential future consequences. One potential solution for this problem is lab-grown beef, which demands very little from the consumer and would take pressure off the environmental issues the beef industry creates. Lab-grown …

Cost-Benefit Analysis Of A Genetic Marker On Cow-Calf Operations Differentiated By Pasture And Breed, Josh C. Crystal, Michael P. Popp, Nathan P. Kemper, Charles F. Rosenkrans Jr.

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Genetic sequencing in beef cattle (Bos taurus L.) is expected to aid producers with selecting breeding stock. Using data from experimental trials conducted with Angus, Brahman, and their reciprocal cross, the single nucleotide polymorphism (SNP) P450 C994G marker expression was investigated for use in selecting genetics suited to grazing endophyte-infected tall fescue (Festuca arundinacea Schreb. L.) compared to bermudagrass (Cynodon dactylon L.) pasture. The study is unique in the sense that actual cow-calf breeding failure rates (open cows were not culled) were tracked from 1991 to 1997 on herds that were bred to calf in spring and were either exposed …

Risk Assessment And Decision-Making For Genetically Modified Foods, Aynsley Kellow

RISK: Health, Safety & Environment (1990-2002)

The author examines concerns about genetically modified foods and how those concerns have developed into policy responses markedly different in Europe than in the United States.

Improving Feed Grains, Bruce P. Mullan

Journal of the Department of Agriculture, Western Australia, Series 4

Clearly, to encourage grain growers to focus their production systems towards feed grains, it is important to first identify the reasons for variation in the nutritional value of grains and then to develop rapid, cheap, and accurate methods of measuring these factors. The analytical methods should ideally be suitable for application either at the site of grain delivery from the farm or within the place of stockfeed manufacture. This will mean the nutritional value of the grain can be known before it is used. The rational marketing of feed grains could then be achieved, with the benefits from more efficient …

Other On-Station Activities For Wool Pastoralists, Mark Stevens

Journal of the Department of Agriculture, Western Australia, Series 4

The impact of low wool prices has been most severe on specialist wool growers who have little scope for diversification, particularly those in the pastoral area.

Although there are limited opportunities for new enterprises on all pastoral stations, individual pastoralists are examining other on-station activities to determine which ones might be suitable. In doing so, they are evaluating:

• location (proximity to a major highway or population centre);

• natural attractions (coast, gorges, river, wildflowers);

• natural resources (native fauna and flora); and

• water supply (quantity and reliability of good quality water).

Tough Times Call For A Review Of Farm Business Performance, Martin Van Bueren, John Young

Journal of the Department of Agriculture, Western Australia, Series 4

Most Australian farm businesses specialising in wool production are operating at a loss at current wool prices. After both short term operating and long term costs of capital depreciation are accounted for, only a small number of wool growers are able to make a profit with the wool market indicator below 500c/kg.

Poor prices have stimulated wool growers to review their operations and look to ways of improving cash flow in the short term, such as diversifying into cropping. The downturn should also prompt growers to address the longer term trends of declining terms of trade and historically poor productivity …

Prospects For Leucaena On The Ord, D Pratchett, Tim Triglone

Journal of the Department of Agriculture, Western Australia, Series 4

For the past few years, the Department of Agriculture has been fattening cattle on the forage shrub leucaena which is grown under irrigation with pangola grass. About 400ha of leucaena is under commercial production in the Kimberley.

Cattle grazing leucaena show promising growth rates but other problems need to be overcome before its use is more widely adopted. Leucaena establishes slowly. It is also costly to transport fattened cattle to southern abbatoirs.

Producing 20-Month Old Beef Steers Off Annual Pasture, K D. Greathead, D. J. Barker, W. J. Ryan

Journal of the Department of Agriculture, Western Australia, Series 4

A recent Mt Barker experiment compared two systems of fodder conservation with continuous grazing, using two types of steers, at three stocking rates. Year-round performance, carcass composition, and resulting costs and returns per hectare were assessed.

Production per hectare was greatest from crossbred steers at the intermediate stocking rate with either type of fodder conservation.

Ryegrass Disease Could Spread, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The disease annual ryegrass toxicity kills sheep and cattle grazing pastures which contain infected annual ryegrass. In Western Australia the first confirmed outbreak was in 1968 in the Gnowangerup area.

The disease has noe spread over a range of 450 kilometres and with a total area of perhaps 100 000 hectares. because annual ryegrass is the major sown pasture grass in W.A. the disease could spread throughout the South-West.

There are some precautions that can be taken.

Cotton Fireweed : Potential Poison : Research Roundup, J Dickson, R. Hill

Journal of the Department of Agriculture, Western Australia, Series 4

Although long known as a potential toxic species because of its content, and although it is widely distribuited in all Australian States, cotton fireweed has not generally been consdidered toxic because it is unpalatable and not usually eaten by stock.

In 1973 cattle deaths occured near Ravensthorpe which led to research into Senecio quadridentatus (cotton fireweed).

The plant must be seen as a potential toxic species in situations where the lack of other feed forces cattle to eat the normally unpalatable cotton fireweed.

Lupinosis, M R. Gardiner

Journal of the Department of Agriculture, Western Australia, Series 4

In spite of many years of intensive investigation lupinosis remains a remarkably complex and baffling problem. Current research is throwing new light on the disease and it is now much better understood— although far from beaten.

Lupinosis research is co-ordinated by the Department of Agriculture's Lupinosis Committee, on which are represented all groups working on the disease. These include veterinary surgeons and pathologists, chemists, plant pathologists and animal husbandry specialists.

Chairman of the Committee is Dr M. R. Gardiner, Chief of the Department's Animal Division and a veteran of lupinosis research.

In this article Dr Gardiner summarises the current state …
