What it takes for a persistent alfalfa stand (new insights)

     Alfalfa has been getting a lot of attention from forage research lately, given concerns that the big seed marketing brands  (generally owned by chemical companies today)  have been selling off or dropping their premium alfalfa lines.     Industry observers site three reasons:  (1) these companies make more money producing corn and soybean seed than alfalfa:  (2)  over the last twenty years, alfalfa growing farms have plateaued yields around 4 tons per acre  (bringing all the genetic selection efforts  into question):   (3)  RoundUp Ready alfalfa never got further than the irrigated fields of Idaho, costing 50% more than conventional seed without promising any increased yields.     Conventional seed sales volume plateaued for several years now.

A new technique for extending alfalfa stand life  

We already knew that the ideal soil pH for alfalfa to grow and persist is 6.5.      Less thought has been put into the ideal soil nutrient ratio for alfalfa, which is 20 parts Carbon to 1 part Nitrogen. Soil microbial populations that feed nutrients to the alfalfa roots are maintained at these levels.

During the harvesting season, each cutting removes carbon.    Alfalfa leaves are not that great at drawing in carbon dioxide (grass species are much superior to legumes in this process).    Thus a “pure” alfalfa stand will begin to die off just from periodic harvesting.     Mixed stands of alfalfa and improved grasses do much better (the alfalfa draws in nitrogen to root zones, and the grass draws in carbon to the root zones);  thus yields from mixed alfalfa-grass stands will be greater over the life of the stand.    But if you planted “pure” alfalfa, just overseed forage oats into the alfalfa stand after last cutting, and they will restore carbon to the soil.   The oats die off during winter, and you will see a more vigorous alfalfa regrowth in the spring!!

Spring  calving  coming  soon:    Ordering  semen  for  spring  breeding  

How efficient is your semen tank?

Semen tanks are not all alike.    We have now used cryogenic (liquid nitrogen) semen storage for sixty years in the cattle breeding industry.    Some 30/ 40/ 50 year old equipment is still in use.    This is amazing, given the more reputable tank builders still only warranty new tanks for five years…    

Considerations in choice of tanks
The first question is,  “does my tank retain a nitrogen charge a practical length of time, so that it fits into available service routes?”     For most people this will mean a tank capable of a 12-week hold, so it has a safety margin on our eight-week service schedule (we could get snowed out of your neighborhood for a week in a bad winter storm, or have a truck breakdown that takes us a week to get fixed).

The second question is, “am I going to be storing any embryos?”    The embryo is so much more complex than the sperm cell, making it more fragile, it is best it remain as much as possible in liquid nitrogen immersion.    Thus with eight week service routes, tank that has a safety margin after sixteen weeks (such as the newest 20-week hold time models) would insure your embryo is not forced to rise to vapor temperature (-140 F) and plunge back down to liquid temperature (-320 F) on a recurring basis.

The third question is, “how much semen am I going to be stocking?”    We all seem to have the tendency to let semen inventory “breed” (multiply) in our tanks.    Once canisters are filled with canes, it is harder to locate the bull you intend to breed with, maybe harder to extract a straw with the canes all gripping each other.    Newer model tanks of standard size have slightly larger canisters than the earlier models, thus IF you can discipline your buying, you can avoid making the straw extraction from the canister for each breeding slower, putting your stored semen at risk of damage from temperatures rising above -140 F vapor temperature.

The fourth question is, “am I a breeder collecting herdsires, thus needing more tank capacity?”   Keep in mind that larger capacity tanks, especially with bigger neck tube openings to handle wider canisters, cannot retain nitrogen as long as standard size tanks.    You might consider an option to store semen beyond your seasonal use at a storage facility rather than have it all on your ranch.    Otherwise, to spread risk, you could have multiple tanks on site and not keep all of your rare herdsire in a single tank  (eventually, every tank ever made is going to fail—we just have to be prepared for a possibility we do not catch it before it goes “warm” and spoils all the semen content in it.

Mark measures every tank we fill, before he puts nitrogen in it.    Those measurements get written at the bottom of your delivery invoice.    Thus we try to help you monitor each tank.

Best wishes to you and your family for a blessed holiday season

We appreciate the opportunity to be of service in your genetics and reproduction program.

New  “Cattle Vision”  sire catalogs should be printed right after the coming Denver stock show  (the industry’s meet and greet event).

The Byron Seeds “early Order Guide” is available if you want to get any spring seed needs reserved.

We are happy to announce that nitrogen service prices should be stable for next year.   We will have confirmed prices for 2026 from our supplier usually in January.

Confirming pregnancies on weaned-off cows and first-time heifers

We continue to stock the EmLabs “P Test” which is a urine test for pregnancy hormones.     Very accurate once a pregnancy is past 60 days.     If you did early confirmations with ultra-sounding it is still a prudent idea  (especially if you are close on winter feed supplies)  to recheck animals who are past the 90-100 day mark, when the gravid uterus has sunk into the body and becomes difficult to reach with ultrasound equipment.   Lots of animals under the stress of a heavy nurse-calf can lose early-day pregnancies, as full “fetal attachment” does not occur until six+ weeks.

Keeping calves warm and dry when born in damp winter

  We introduced “calf jackets” and “calf earmuffs” at last year’s Michigan Cattleman’s Association Beef Expo.    We intend to have a “meet and greet” booth at the MCA event again this year with displays of our product lines.    The latest in calf jackets will be on display then, but if you expect to have special calves born this winter, we have them in stock.

The importance of good pelvic structure for lifetime cow function

 

As we study skeletal structure in dairy cows, we should grasp how “three dimensional” pelvic capacity needs to be, for a cow to succeed in all these functional expectations:

The pelvis houses the mammary system
The dimensions of a productive and long-lasting UDDER depend on the cooperation of pelvic bones and the capacity they create.    All the supporting “girdle” to the udder (both center and multiple lateral ligaments) are suspended from the pelvic bones.    A level pelvis with a larger interior spread will help to keep the udder floor level for her entire productive life.

The pelvis contains the calving channel and aids in timely reproduction
Broad hips, wide thurls and “open” pins reduces the chances of a calf getting “stuck” during the delivery process.   Calving Ease really starts with a fully three dimensional pelvic bone structure.
The involution of the uterus after calving is enhanced when the pelvis has proper interior slope from hips to pins, and has allowed minimal trauma to all the interior muscles during parturition.

 
The pelvis is the anchoring point for the hind legs
Hind legs begin with their “thurl socket”, enclosing the swivel ball in the base of the pelvic bone formation.    When the thurls are “wide” it sets the legs out to the side from the body, minimize squeezing of the rear udder between legs that can abraid the udder ligments during movement.
The closer to “central” that thurl position is within the length of the pelvis, the better will be the weight bearing on the foot (minimizing uneven growth requring frequent hoof trimming).

The pelvis can aid in ease of rebreeding cows for their next calving
When thurls are too far back, the pins rise and hind legs kick out behind the cow.    This shifts rear end weight onto the loin, which is not designed to carry that added stress;  flattening the spine, leading to abraded or pinched nerves passing across the back to run rear end functions.
Cows with level pelvis, central thurl, straight spines, get through calving easier, recover faster for rebreeding, and when you have your arm inside to breed her you find the cervix where it needs to be for easier insemination.    

How does the “aAa” process aid you to consistently produce desired pelvic shape?

aAa #1 “DAIRY”  can make hips broader, setting up the forward pelvic dimensions.
aAa #2  “TALL”    helps to raise hips above pins, so you have the proper interior slope.
aAa #3  “OPEN”  helps to make the pelvis wider between thurls and pins for easier calving.

Mating selection can simultaneously increase milk check income potential and also extend the functional lifetime potential   IF you choose bulls in this way.

Inside you will find a discussion on shifting component selection in favor of more Protein while maintaining butterfat  (what traits to consider first).

You will also find a discussion on the importance of pelvic structures for all those functions we expect from a cow   (the most direct guides to make desired change)

It is in the nature of any commodity production, that the model that produces a commodity at the “least cost” generates profits, whereas trying to maximize yield generates increased costs;  incremental yield gains can cost more than they give us in profit.    We can apply genetic selection better to lower costs first, improve yields only as they can provide increased income at a below average cost.
