Drought
conditions have made their mark on US forage production, shifting the
distribution of forage towards greater production of corn and sorghum silage as
harsh drought conditions in 2012 led to a decrease in the production of alfalfa
and alfalfa mixtures, according to the USDA Crop Production 2012 Summary
Report.
In light of the overall forage shortage in much of the country, farmers need to be shrewd and economical about rationing their forage inventories. Nutritionist Steve Massie of Progressive Dairyman suggests three basic strategies to prolong your forage supply while ensuring your cows receive adequate fiber: “harvest it, buy it, or stretch it.”
If you harvest
non-traditional forages to add to your supply, there are generally two ways to
use them. If they are of good quality, you can add them in as feed; otherwise,
they can replace traditional bedding, mainly straw, so that the bedding can be
used as feed (Massie notes that he has fed up to six pounds of straw in
lactation diets without hurting peak milk). Get creative about what you can
harvest! There are a number of small-grain crops you can harvest in early
spring to supplement your forage inventory (triticale, rye, oats, barley wheat,
spelt).
If you
decide to purchase forage to add to your inventory, unfortunately, a national
shortage of forage means that prices won’t be cheap. The key is to buy the
best-quality product for the price, keeping in mind that hay should be
purchased on high RFQ (Relative Feed Quality). To stretch your forage supply, opt
for a high-NDF grass or mixed hay with a friendlier price tag than alfalfa.
One more
option available to you is to stretch what you have by replacing more of your
forage with byproducts. The trick is to balance high-NDF feeds that contribute
to the rumen fiber mat (such as whole fuzzy cottonseed, citrus pulp, almond
hulls, beet hulls, cottonseed hulls, and cottonseed burrs) with high-NDF feeds that do not contribute to
the rumen mat but DO replace more fermentable carbohydrates in the diet. Balancing
low-forage diets requires a relatively sophisticated ration balancing program
as great care must be taken to avoid jeopardizing your herd’s health and
butterfat content.
In harsh
growing conditions for traditional forage, the good news is that by harvesting
additional forages, purchasing supplemental forage, or by judiciously
stretching what you already have, you do have options to get more mileage out
of your forage supply!
