BOA Injection Site Recommendation Changes
In the early 1990’s, the cattle industry began to move to Beef Quality Assurance (BQA) protocols that are now in wide spread use. Injection site lesions were one of the main problems addressed. The effort was very successful with beef quality audits showing a reduction of injection lesions in the top butt, round and loin. The preferred injection site introduced in the early 90’s is shown in the larger triangle in the figure below.
The food
industry has introduced new cuts utilizing 
the
chuck and switched to a modified
atmosphere (MA) packaging process for case-ready meats. The MA
packaging contains 80% oxygen and 20% carbon dioxide mixture, which can
cause a green discoloration of meat close to the injection site. To
remedy this marketing problem, the BQA program is promoting the
smaller injection area triangle shown in white.

Web Survey Collects Farm Opinions on Biosecurity
Do
agricultural producers think a bioterrorist attack might strike water,
livestock, crops or the U.S. food supply? How can they prepare for or
respond to such incidents? The Extension Disaster Education Network (EDEN)
will provide homeland security education for farm and non-farm
industries and individuals to answer these types of questions.
A web-based survey will ask producers across the
country for their opinions on such biosecurity and agroterrorism topics.
The producer survey results will guide what types of educational
programs should be offered on agricultural biosecurity. The EDEN
project will help measure agricultural producers’ perceptions
about biosecurity issues on the farm.
To take the survey, producers may visit the EDEN web site at http://www.agctr.lsu.edu/eden and click on “Homeland Security Surveys,” then click on “Survey of Ag and Horticulture Producers". The survey is anonymous, takes less than ten minutes, and needs to be completed by the end of November. For producers without web access, stop by your local Extension office.

Reducing
Stress on Calves at Weaning
Physical, environmental, nutritional and social stresses commonly impact calves at weaning. Traditional weaning systems typically stack two or more of the stressors together and cause problems with reduced calf health and performance.
When designing weaning programs to reduce the number of stressors occurring at once, consider the following:
Physical stress factors (castration, dehorning, vaccinations) should be completed prior to weaning.

Pasture Weaning to Reduce Stress on Calves
Pasture weaning offers a low-stress alternative to conventional drylot weaning programs. In a pasture weaning program, it is important to have high quality pasture available at weaning. For fall weaned calves, hay field re-growth or stockpiled fescue provide excellent choices for pasture weaning.
The idea that
weaning fences need to be five feet high and “chicken tight”
applies to traditional drylot weaning programs where calves are looking
for a way to escape multiple stressors. 
With pasture weaning, three-strand electrified hi-tensile fences have been used very successfully. For cattle with limited exposure to electric fence, a pasture with either woven wire perimeter or at least five electrified wires will probably be required for weaning. Adding an offset hot wire to an existing 4 or 5 strand barbed-wire fence may also serve to keep calves in place.
‘Across-fence weaning' reduces social stress by allowing the dam and calf visual and scent contact.

To optimize pig performance, monitor the following feed quality issues:
 |
Particle size should be kept between 700 and 800 microns. When they first begin to monitor particle size, many producers find they are feeding a diet with a particle size of 1000 microns or more. A larger particle size reduces feed efficiency. Grinder management is the key to reducing particle size. |
|
|
Diet formulation needs to be evaluated to ensure unnecessary ingredients are removed and specific nutrients are not being ‘over fed’. Adjust diets to account for ‘new crop’ corn problems. Watch for mycotoxins – they may be more prevalent this year. |
|
|
Adjusting feeders properly reduces feed wastage by requiring pigs to work the agitators to get adequate feed flow. Feeder troughs that are ¼ to ½ full, waste feed! |

As the hog market and feed prices fluctuate producers need to determine their optimal market weight. The table below indicates at low hog prices and high feed costs, economic efficiencies may be obtained by marketing at lower weights. Remember – these tables only account for feed costs – other costs are not included.
Historically shackle space has become limited in November and December. Schedule shackle well in advance!

Taxation Tidbit: Annual Gift Exclusion
Increased for 2002
The annual gift exclusion has been limited to $10,000 for a number of years. Starting in 2002, each person (donor) can give up to $11,000 of assets each calendar year to as many people as they are financially able and willing - without incurring any federal gift tax liability. The annual gift exclusion provides a means of transferring a substantial amount of wealth out of an estate over a relatively short period of time.
Gifts to be eligible for the annual exclusion must be gifts of a “present interest”. In contrast, the transfer of an asset while retaining the right to the income from that property for the remainder of your life is a gift of a future interest and would not qualify for the annual gift exclusion.
