Nf00-429 Controlling Pond Algae With Barley Straw, John C. Holz

University of Nebraska-Lincoln Extension: Historical Materials

Algae are microscopic, free-floating plants which comprise a critical component of a lake's food web. They are fed upon by tiny animals called zooplankton which are an important food source for fish. Algae color the water green or brown, and uncontrolled growth can lead to nuisance surface scums, poor water clarity, noxious odors and an overall reduction in the lake's recreational value. Excessive levels or "blooms" of algae occur when nutrients, especially phosphorus, are abundant. After taking steps to reduce the amount of phosphorus entering a lake, it may be desirable to control the algae growth directly. Typically this is …

This NebGuide provides poultry producers with information on how to market poultry directly to customers. It includes information on pricing, regulations, processing and relationship marketing.

The decision to market meat poultry requires a basic change in the way growers think about production. The question is no longer how many birds I can raise but how many I can sell at a reasonable profit.

Pricing

Several factors must be considered in pricing. First, determine the average amount of profit you need from each bird. Second, know your average cost to produce each bird. Finally, discover prices charged by others who are …

G00-1411 Biosecurity Basics For Cattle Operations And Good Management Practices (Gmp) For Controlling Infectious Diseases, Marilyn Buhman, Grant Dewell, Dicky D. Griffin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide introduces cattle producers to the concept of biosecurity and provides practical management recommendations for preventing and/or containing infectious disease.

Biosecurity

The goal of biosecurity is to stop transmission of disease-causing agents by preventing, minimizing or controlling cross-contamination of body fluids (feces, urine, saliva, etc.) between animals, animals to feed and animals to equipment that may directly or indirectly contact animals. Biosecurity management practices are designed to prevent the spread of disease by minimizing the movement of biologic organisms and their vectors (viruses, bacteria, rodents, flies, etc.) onto and within your operation. Biosecurity can be very difficult to maintain …

Comparison Of Photosynthetic Water Use Efficiency Of Sweet Sorghum At Canopy And Leaf Scales, Mustafa Ünlü, Pasquale Steduto

Turkish Journal of Agriculture and Forestry

Little is known about the response of sweet sorghum to water stress. Therefore, the aim of this study was to characterize sweet sorghum physiological water use efficiency (WUE) under progressing water stress conditions, with emphasis on the canopy scale as compared with the leaf scale. Sweet sorghum ( Sorghum bicolor(L.) Moench) was subjected to two water stress cycles. Energy, water vapor, and CO 2 fluxes were estimated at the canopy scale by means of the Bowen ratio/energy balance/CO 2 gradient method (BREB+), and at the leaf scale with a portable photosynthesis system. Predawn (yb) and noon-time leaf water potential (yn) …

Effect Of Zinc Microelement On Quality Of Some Wheat Cultivars Grown In Central Anatolia, Gülcan Kinaci

Turkish Journal of Agriculture and Forestry

Almost half of the cultivated areas of Turkey have been found to be zinc deficient. This deficiency is even more serious in Central Anatolia, the large cereal-producing region. Zinc is an essential element for nourishing plants, and also for normal development and functioning of humans and animals. Meeting the daily zinc requirement from diet is very difficult for people whose daily energy intake is based on cereals. However, wheat bread by itself contributes 40-70 % of daily energy intake for Turkish people. One way to overcome this problem is by increasing the zinc content of wheat by applying zinc to …

Western Australia - A Johne's Disease Free Zone, Peter Morcombe

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

The control of Johne's disease (JD) in Australia is coordinated nationally by Animal Health Australia in conjunction with the livestock industries and the Commonwealth and State "Governments. Zones were established for Australia in July 1999 to control the spread of JD. These zones ensured that surveillance established the prevalence of JD, and that movement restrictions on livestock appropriate to the zone status were implemented. Following many years of surveillance and restrictions on the introduction of livestock, Western Australia has now been declared a Johne's Disease Free Zone - the first in Australia. Johne's Disease State Coordinator Peter Morcombe looks at …

Crop Quality And Utilization: A Twelve-Hour In Vitro Procedure For Sorghum Grain Feed Quality Assessment, Jeffrey F. Pedersen, Todd Milton, R. A. Mass

Department of Agronomy and Horticulture: Faculty Publications

Improvedmethods for assessing cereal crop feed value are a prerequisite for the genetic improvement of sorghum [Sorghum bicolor (L.) Moench] feed value. Rate of starch digestion is now commonly believed to be the limiting factor in sorghum utilization by cattle (Bos taurus). However, techniques to assess this trait are not useful to sorghum breeders because of high labor inputs, lab error associated with starch measurement, and need for high numbers of replications. The objective of this study was to develop a simple technique capable of identifying differences in digestion between sorghum and corn (Zea mays L.) …
