Buying direct from farmers - Consumer Training Modules - Talking about Grassfed

Over the last few years of dealing directly with clients, I realized how much the majority of consumers have been disconnected from where their food comes from.  Discussions about cuts and other meat buying terms are met with blank stares.  So I have decided to write a series of training modules that eventually will be used for a consumer training seminar that I will be giving in Ottawa later this summer. The seminar will be "How to buy meat directly from farmers" and cover topics such as sourcing from farmers, defining confusing terminology, cut charts, ordering and pricing, what questions to ask and how to make the transaction "win win" for everyone. The time and date will be announced later this spring.

I have decided to start with a term that is often bandied about and equally often misinterpreted not only by the consumer but also by the farming newbies. That term is grassfed.  

Most think of grassfed in the literal translation, that is fed on grass ...which is true.  However raising grassfed livestock is both an art and a science that goes WELL beyond throwing livestock out on pasture and expecting to have marketable meat of any quality at the end.

First lets start with a discussion of cattle and sheep.  Consider their wild origins and how the original animals would have fed.  Wild species would travel in groups, constantly moving and eating a range of plants from grasses, legumes, broad leafed plants and tree and bush browse.  They would rarely stay in the same place for long nor return to the same place in a year.  The area they would cover would be huge and the relative animal density would be low.

Now consider contemporary pasture management especially in eastern North Amerca.  Western rangeland is a bit different.  The relative animal density is high, the plant variety in their diet is quite limited and the grazing area is relatively small.  Unless well managed, animals could be subject to dietary imbalances, parasites overload and poor gains.  So dear consumer recognize that the term grassfed is not a guarantee of a healthy, well-raised animal.

 At its best meat from grassfed animals is rich, tender and flavourful.  At its worst, meat from grassfed animals is dry, coarse and tastes metallic.  One of the major differences to quality is finish, the balance of fat to muscle which blended leads to moist, tastely meat.  

Yes, I know that many of you want lean but I am here to tell you that you need fat for a number of reasons most of which is flavour.  When push comes to shove, the flavour is in the fat.  We have had clients demand lean ground.  We complied and then got complaints about how dry it was, how it fell apart and how bland it was.  Now I nod and give people what I know they will like.  If you are worried about calories, just cut down the amount you eat.

The other reason you need fat is to protect the meat and keep it moist.  A complete layer of fat is needed to protect the meat during the aging process.  If that fat is not present, the meat oxidizes, goes black and takes on a metallic flavour.    

You also need some marbling, the fat that is delicately threaded through the muscle to keep it moist during cooking and enhance the flavour.  The reason why KobĂ© beef is so prized is the level of marbling through the meat. Meat without any internal fat is dry and flavourless.

Now what has this got to do with grassfed?  It is extremely difficult to finish meat on grass alone at a young age.  Most cattle do not start to naturally develop marbling until they are over 2 years of age.  Most beef is processed before that time.  

The other issue is it is very difficult to finish meat on both spring and fall pastures.  It has to do with dry matter intake and other technical topics which are a whole lot more information that the average consumer needs  or is interested in.  Think of it this way.  If you had a diet of exclusively iceberg lettuce, how balanced would your diet be?  You could not eat enough iceberg lettuce to meet your nutritional needs because of the water content.  That is the same problem with high water level spring and fall pastures.OK this is a bit too simplified but you get the picture.

The final note about grassfed that strangely Canadian consumers forget about is winter.  No the animals will not be on pasture year round.  They do need to be fed during the winter.  Yes they can be fed grass during the winter in either hay or haylage.  They are still grass fed.

While our animals are predominately grass fed, we do supplement with grains during the periods of fast growth and heavy demand on the ewes and the lambs to avoid energy inbalance. We are working towards exclusively grassfed but not before we can manage our pastures in a way to meet all the nutrional needs of our animals without compromising their health.  

Now quickly I will touch on grassfed or pastured chickens.  First and foremost chickens are not exclusively herbivores.  They are omnivores.  They do need a balance of greens, grains, and critters to balance their diet.  Chickens out on pasture should still be predominately grain fed with pasture supplement.  So do not think that chickens get all their nutrition from pasture.  They do not.  And I would steer away from producers that claim their chickens are raised exclusively on pasture.  The resulting product will probably be thin and dry.  Talk to a butcher that has had to slaughter exclusively pastured chickens.  Our laying hens range free during the days from spring to fall.  I feed them nearly as much grain during that time as I do in the winter. Do their eggs taste different between winter and summer?  Absolutely.  The dietary additions during the ranging period change the flavour and quality of the eggs but it is not sufficient to maintain all the nutritional needs of the chickens.

Are their health reasons for buying grassfed meats?  Yes, there is data that shows the omega 3 fatty acid levels are higher in meats from animals raised on grass than those that are exclusively grain fed.  

I hope that this series will help the consumer that wants to buy direct from farmers.  An informed consumer will inprove the transaction for both parties.  

Let me know if there are topics you would like me to cover.  My next topic will be "that confusing cut chart".

TTFN,

Why we don't go against nature at Hawk Hill

I read with interest the article in the Ontario Sheep News on fish meal supplementation to supply omega 3 fatty acids in ewe ration and its impact on the subsequent lamb's ability to withstand a bacteria toxin challenge (endotoxin).  While it was scientifically interesting, this is not the direction that our farm wants to go.

The first reason is that sheep are herbivores, not omnivores, and feeding animal-based proteins to herbivores is what got the sheep industry into problems in the first place with conditions like scrapie.  No, I am not saying that fish meal can transmit scrapie, but I am questioning a nutritional supplement that is so totally foreign to the natural diet of sheep.

The second reason is the effect of the fish supplement on the quality of the meat.  As a teenager, we lived in Sweden.  At that time, the Swedish pork industry was using a fish based feed supplement.  It was, beyond the doubt, the worst pork I had ever eaten with a distinctly fishy flavour to the meat.  We do not want to use any feed supplement that can create off flavours in the meat and reduce the quality of our product.

Man's manipulation of domestic animals is but a moment of time in the evolutionary scale.  That is especially true with respect to recent manipulations for the more intensively raised livestock.

Sheep have evolved to breed at a time so that the lambs were born when vegetation is young, supporting the increased nutritional demands for a lactating ewe as well as for a rapidly growing lamb.  In our climate's case (and the British and European breeds that have evolved for our climate) that means a birth in April or May.   Not surprisingly, omega-3 fatty acids in forage peak at the same time as lambing.  Forage sugars and proteins also peak at that time.

All this begs the economic and in some cases physiological costs of trying to paddle against nature's current.  In my opinion the way to minimize health problems and economic costs in your flock is to quit trying to breed out of season. 


The demand for Easter lamb actually originated in the Mediteranean  where the climate naturally produces lamb in that season.  So is it reasonable to expect production systems in a northern climate using breeds developed in northern climates to try to mimic a Mediteranean production system using Mediteranean breeds?  My opinion is no.


 Does that mean only seasonal availability of lamb?  Sure, but it is a long season from spring lamb in May, June to heavy lambs from September to January or even later.  Off season, there is hogget and mutton, two very good meats that need to be promoted again. 


Each shepherd must make their own decision as to the production system they want but they must recognize going against our climatic realities comes at an economic and management cost. At Hawk Hill, we acknowledge the realities of our climate, our breeds and our forage production season and manage our breeding and marketing to reflect that reality.
