American Wool Assurance Program

American Sheep Industry
(American Wool Assurance (AWA) homepage)

The American Wool Assurance website launched today at AmericanWoolAssurance.org, allowing American sheep producers to take a crucial step in certifying their wool through this voluntary, American industry-driven certification process.

The American Sheep Industry Association worked with Colorado State University the past two years to develop the voluntary program and standards that will allow manufacturers to purchase American wool with confidence that the animals producing that wool have been raised with a high level of care. Industry input from producers, shearers, buyers, extension, animal welfare experts and processors was critical in development of program standards.

Neonatal Lamb Management: Intraperitoneal Injection of Dextrose (Glucose)

Most lamb deaths that occur shortly after birth are due to starvation and/or hypothermia (low body temperature). These losses are most often preventable, and lambs can be saved if problems are identified and treated quickly.

Why is timing important?

  • Newborn lambs rely on reserves of brown fat as an energy source until they ingest colostrum. Ideally, lambs will nurse and receive colostrum within two hours of birth. If feeding is delayed, even by a few hours, fat stores will be depleted. Unless the lamb nurses, or receives another source of energy, it will become unconscious and die.
  • Long-term survival also depends on receiving colostrum soon after birth, as the ability to absorb antibodies in colostrum quickly decreases. Milk or milk replacer will prevent starvation but will not protect against infections.
  • The sooner an ‘at risk’ lamb is identified, the easier the treatment and the greater the chance of saving the lamb.

Multi-Species Grazing as an Alternative to Pasture Spraying

Broadacre spraying of pastures is intended to reduce undesirable plants and increase grasses for livestock. This practice often results in unintended consequences including damage and reduction of native forbs and reduced profitability. One approach to managing perceived “weedy” plants that can offset those negative outcomes is incorporating different species of livestock into a grazing operation.

All species of livestock have different dietary preferences, and producers can harness this to help manage their plant communities in an ecologically and economically sustainable manner. Small ruminants, in particular sheep and goats, are the most common livestock species that are added alongside a cattle enterprise.

All species of livestock have different preferences when it comes to selecting the species of plants they consume, as demonstrated in the image above.

Spider Syndrome in the Sheep Flock

Spider Syndrome is a genetic problem, common in the Suffolk breed and becoming more common in the Hampshire breed. Spider syndrome has been compared to dwarfism in beef cattle. It has been prevalent since the 1950s. Spider syndrome has also been diagnosed in commercial flocks that keep brockle-faced lambs back as replacement ewes. Those ewes are coming from Suffolk or Hampshire rams that carry the syndrome. Researchers feel certain that spider syndrome is caused by a simple, autosomal, recessive gene. If a producer has a flock of carrier ewes and breeds them to a carrier ram, one-fourth of his or her lamb crop could have spider syndrome!!!

Diagnosis
Spider lambs are affected in one of two ways: 1) lambs are abnormal at birth and will probably never be able to stand, or 2) lambs appear normal at birth, but develop into a spider lamb at two weeks to six weeks of age.

3 Constituents Beyond Protein and RFV

Often, I consult with livestock producers testing forage for their animals. Inevitably there are two numbers on the report they are most concerned with, protein and relative feed value (RFV). Protein is an important value to understand if the forage meets animal requirements, and RFV is a useful index to quickly compare or rank forages.

However, examination of directly measured constituents can help producers understand the characteristics of that forage as it pertains to feeding livestock. So, here are three other constituents to consider when evaluating a forage for livestock feed.

1. Acid detergent fiber (ADF)
This is the least digestible portion of the feed, made up of Continue reading →
