Alfalfa Guide Harvest

Memo

Alfalfa is superior to other forage crops and understanding how alfalfa grows and its relationship to forage yield & quality is critical to high quality production.

ALFALFA HAY GUIDELINES

Memo

The quality of alfalfa hay used as feed, can be determined from the ADF, NDF, Relative Feed Value, TDN and crude protein levels.

Alfalfa Mangement Guide

Memo

The final step to profitable alfalfa production is to set goals for forage quality and use the appropriate harvest techniques.

Analysis and Supplements for Beef Cows

Memo

Determining if a supplement is needed for beef cows is based on forage quality and can be guided by a forage analysis which measures several components.

Analysis of Total Starch – Summary

Memo

Starch analysis involves two basis steps. The first is the enzymatic hydrolysis of starch in glucose. The second is the measurement of glucose levels.

Animal Feed Fee Schedule

Composition of Fiber in Feeds

Memo

Fiber can be broken out into three different fractions, Crude, Neutral Detergent and Acid Detergent. Each of these fiber fractions are made up of different components.

f

Feed Nitrate Testing

Memo

Nitrate in plants are usually converted to proteins, amino acids and other compounds. However some stresses to the plant can cause toxic levels of nitrates.

Field Guide for Hay and Silage

Memo

Silage and hay are the most common forms of storage for forages. Silages are usually preferred by livestock to hay.

g

Glycerin As Feed

Memo

Glycerin is odorless, colorless, water soluble, and has a sweet taste. And the feed value in terms of energy could be equal to corn.

l

Listeria Monocytogenes

Brochure

First described as a pathogen in the late 1920's, it was not until the early 1980's that Listeria monocytogenes emerged as a food-borne pathogen. These hardy, nonspore-forming bacteria are capable of growing over a temperature range of 1-45o C (34-113o F), growing best at 30-37o ...

Nitrate Toxicity

Memo

Forage diets high in nitrates could cause nitrate toxicity when the conversion of nitrite to ammonia becomes the limiting factor.

p

Particles Size Analysis for Swine Feeds

Memo

A general guideline for particle size interpretation shows an average particle size of 700-800 microns is considered acceptable for all classes of swine.

Peroxide Value

Memo

Evidence of rancidity in fats and oils can be evaluated by the detection of peroxide. The Peroxide value analysis is the most widely used.

Prussic Acid Poisoning and Nitrate Toxicity – Sudangrass Grazing

Memo

Taking precautions when grazing sorghums and sudangrass will provide safety against hydrocyanic acid or prussic acid poisoning or nitrate toxicity.

Rapid Visco Analyzer Results

Memo

Following is a brief introduction to the Interpretation of pastling curves for starch-based samples testing using your RVA 4500. A heat-hold-cool cooking cycle is assumed. A good textbook covering polymer hydrocolloids should provide further information on these processes and on starch chemistry, modification and uses.

Relative Feed Value (RFV) of Forages

Memo

Relative Feed Value (RFV) can be calculated on any set of feed analysis data that includes ADF and NDF, however the equations were developed specifically for alfalfa hay fed to Dairy cows.

Residual Antibiotic Analyses

Memo

The existing science and instrumentation for residual antibiotic analyses is leaning toward the LC/MS or LC/MS/MS methods because of the versatility.

s
