ALTERNATE  MANAGEMENT  PRACTICES

Credit for each idea is given to those who are following the practice.   In some cases more than one "credit" is given for the obvious reason that we see it on more than one dairy.

Once per day milking

In conventional dairying, many large dairies will milk fresh heifers three or four times daily, as a way to stimulate greater appetite, moving out mammary swelling, and a higher production peak.  The conventional wisdom is, if you milk at least heifer and fresh cow pens three times daily, you will gain 15% on production yield-- as much as you might have gained from using rBST but without hassling with injections.    Implicit in this is, the more times you milk, the more feed you need to provide, or your cows will lose condition and eventually neutralize the initial 15% yield gains.

Graziers, on the other hand, especially those who calve in the spring season, and depending on the summer and fall weather may be rationing grass by fall, may go down to once per day milking in the peak summer heat, or after the first frost that stops grass from growing.    Their argument is that "Can you justify the labor and energy to milk a second time, to only gain 15% more milk?"   Unspoken in this is the recognition that, if you do not have the extra feed to make the milk and keep cows in healthy condition, or enough labor to cover a full milking schedule all season, once per day milking allows you to keep the situation stable.

DENNIS GRABILL at Grant, MI and HOWARD STRAUB at St Johns, MI both have tried once a day milking at the end of a seasonal group's lactation cycle.    Dennis (with purebred Holsteins) was pursuing fall season calving, which allowed the bulk of the herd to be dry at the time the summer slump in grass growth hits.  Howard (with Friesians and Friesian-Jersey crosses) pursues spring season calving, which meant the cows would be dried up after the fall stockpiled grass is used up in the early winter.    In  both cases, the idea was, most if not all cows are bred back, in a later lactation stage, and the grass volume is declining.    Once per day milking meant that cows' body condition could be maintained at a time when the udders would not be taxed by having to hold up to 24 hours' milk.    In Dennis' case, with fall calving, once a day milking fell when hay baling (second cutting) was at its peak, so milking was done only in the mornings and a "full" workday remained for the hay harvesting.   In Howard's case, with spring calving, as winter began (which makes chores take longer) the work load could lighten up by avoiding a milking that inevitably would have to occur in winter darkness (as temps decline).

MORE  COMMON  MISTAKES  NEW  GRAZIERS  MAKE

We have personally been through the drill of converting a conventional design dairy into a grass based, intensive rotation design dairy-- and some of the mistakes you are prone to make can be costly.    In order to prevent these mistakes in your farm, we offer these suggestions, some of which may be counter to local advice or your personal inclination-- but still necessary to learn.

Graziers do many things that are different from conventional practice, because they find them a better fit to compensate for the seasonal effects of grass management.    We are beginning a section called "Alternate Management Practices" in which you will find suggestions that will often confuse your more conventional neighbors.    Check it out and if you have such ideas of your own send them to us-- if we like them we might include them.

(1)   'GRASS' IS NOT A 'WEED'

This is the title of another article posted on the website.    The only point not made in the article that matters to you is this:  those trained to dairy in a "non grazing" way will not understand what you are doing and thus will not be good sources of advice on how to do it correctly.   Their preferences may often be to talk you out of being a grazier.    It is possible to be making a living inside agriculture and not be cognizant of what is developing in farming and animal husbandry practices that differ in philosophy from yours-- and this will start with the ignorance of the corn + soybeans + alfalfa farmers that there actually is such a thing as "grass genetics", or that "forage" corn is different from (maybe better for your cows) than "grain" corn.

(2)   PRODUCTION YIELDS ARE ADDITIVE

Most new dairymen, whether conventional or pasture-based, do not start out at the level of milk yields that dairymen with years of experience attain.     The cows you buy to start a herd will not be as "good" as the cows you breed, mostly because incoming cows were used to the environment they left, and have to relearn everything to adapt to you and their new environment.

Adaptation is a basic concept of Biology-- that living beings have to adjust their behavior and performance to the characteristic limitations and opportunities a new environment offers.    In conventional dairying, great effort is put into feeding the "same" feed every day, and in the "same" quantity.    Over time, a production oriented dairyman coaxes his cows to eat more feed, and to digest a feed mix that has an increasing energy density.    Thus the attained level of milk production per cow on that dairy grows as their feed growing, harvesting, storage and mixing skills increase.    But it will also reflect that new environment changing the genes of the animals to mimic what all those changes dictate for cows' functional capabilities.

You can buy cows from a conventional dairy that averages 104 pounds per day, turn them loose in unmanaged pasture, and see their production fall to 30 pounds per day.    This is the result of all the ways in which the environment changed for those cows.      So-- when buying cows-- do not assume that herd x's cows are better than herd y's because of a higher herd average (and thus justify a premium price paid)-- their production level is primarily the result of the management skill of that dairyman within his chosen production paradigm.

Of all the personal qualities of good dairymen, daily discipline in the flow of work has the most impact upon cow performance.    Regular milking times, regular removal of uneaten feed, daily rotation of grazing paddocks to provide a consistent volume of fresh feed, all of these support your level of production.    "The devil is in the details" is an apt description of dairying, and a conversion to grazing does not change your need to be a "manager" of what is a complex production process.   

(3)  SUCCESSFUL GRAZIERS ARE STILL BUSY DAIRYMEN

The worst reason to go into grazing is that you are "too lazy" or too disorganized to do a good job in conventional dairy farming, and tend to run out of feed, or harvest feed of lower nutrient density.    It is proven fact that a systematically rotated grass paddock will produce 40% more feed value than a continuously grazed pasture.     If you are not disciplined to do daily rotation you will also tend to run out of feed as a grazier, without the luxury of stored feed to cover for you, and damaging the production of those paddocks in future seasons.

Genetic Selection in Grazing PDF Print E-mail

How important is genetic selection to a grazier?

Dairymen who have transitioned from free stall confinement to rotation grazing, will tell you “grazing”  adds a year to the average cow’s productive life.    Likewise, the “hybrid vigor” for health and fertility traits from a first generation of crossbreeding will on average add a year to the cow’s productive life.

An extra year of production (which produces an extra calf from each cow, with successful breeding) generally means the grazier no longer worries about keeping his milking cow barn full.   So there is the mistaken belief, shared among many in grazing circles, that you can skip AI and just buy bulls anywhere and stay profitably in the dairy business.

But the physical vigor, structural mobility, and ruminant/abomasal capacity, combined with easy body conditioning, that optimizes a dairy cow’s productivity under grass-based dairying cannot be preserved from random mating or indiscriminate crossbreeding.    The productivity benefit in cross-breeding has a history of peaking with the third-breed cross,-- likewise the fertility benefit from crossbreeding has a history of plateauing quickly when in a two-breed rotation.    And in any generation, the “wrong” bull can give you undesirable traits in udder balance or texture, teat placement or shape, feet or leg structure, or pelvic calving capacity—that cost you extra labor, breeding, or veterinary expenses, or just put a “glass ceiling” on cow milk production.     So you will still be producing cull cows in every heifer crop.
