When we started in the commercial sheep business over 15 years ago, we knew we wanted to use livestock guardian dogs (LGDs) to protect our sheep from predators. LGDs were not as common then in the foothills as they are today, so our choices were somewhat limited - and my knowledge of these dogs was even more limited. One LGD puppy looked much like another (white and fuzzy) - and while I knew enough to pick a pup from working stock, I didn't know the questions I should be asking - or even what I should be looking for in terms of behavior. While we were lucky enough to pick up an older dog who turned out to be a decent protector, our record of success in our early years was mixed at best.
As we gained more experience using LGDs, we started to look for specific traits in new dogs. And we started to realize the importance of appropriate bonding and early-life "training" (I use the word "training" here differently than I might use it with respect to a herding dog - training a LGD doesn't necessarily involve teach a dog specific commands). As I've gained more experience and insight, our record of success has improved.
Over the last six months, I've been collaborating with extension colleagues in California and elsewhere to increase our understanding about what makes a solid livestock guardian dog. Carolyn Whitesell, who is the new human-wildlife interactions advisor with UC Cooperative Extension in the Bay Area, has experience working with LGDs in Africa. Bill Costanzo, who comes from a California sheep background, is a LGD extension specialist with Texas A&M. We've worked to come up with a new fact sheet on selecting the right LGD puppy. You can download it here.
Over the coming months, we hope to produce a series of fact sheets on caring for your LGD, as well as on bonding techniques and problem-solving. Carolyn and I will also be surveying producers about their techniques for bonding LGDs with livestock. Stay tuned!

Note: This post was adapted from my Foothill Agrarian blog.
I've read a number of Twitter threads over the last six weeks that have been focused on supporting local farmers and ranchers during the COVID-19 crisis. I think this is great! Anything that refocuses our food buying habits on local producers is positive, in my opinion. But even at the local level, our food system is a complex network of relationships, business and otherwise. And producing meat, especially pork, lamb, and beef, is even more complicated - by regulations, as well as by basic biology. I thought it might be useful to walk through my own decision-making process when it comes to how we market our lambs.
Fundamentally, we are in the business of harvesting grass and other vegetation with sheep. Through the miracle of rumination, our sheep are able to turn this forage into muscle, fat, bone, fiber, and milk. When it comes right down to it, we're in the business of turning the products of photosynthesis into meat and wool.
As ranchers know, not all grass (or broadleaf forages) are created equal - nor are they of equal nutritional value all through the year. As grazers, we must be concerned with both quantity and quality when it comes to creating an annual forage budget. And we must think about matching our production cycle with our forage availability - in other words, we need to balance supply and demand.
From a quantitative perspective, we have an abundance of green, nutritious forage (in most years) from March through mid-May on our unirrigated rangelands, and from April through late June on our irrigated pasture. After the "summer slump" (when temperatures are too warm for our cool-season forages like orchard grass and clover), we get a second (although lesser) peak in forge production in the late summer and early fall. The most challenging time for us here in the Sierra foothills and Sacramento Valley is mid-autumn through mid-winter - in Auburn, our irrigation water ends on October 15, so we must conserve last year's dead grass until the autumn rains germinate the forage on our annual rangelands.
In terms of quality, we focus largely on protein. The rumen microbes that break down cellulose and provide our animals with energy need at least 7-8 percent protein in the forage the sheep are consuming. Green forage is much higher in protein (typically) than dry grass - the forages on our annual rangelands and irrigated pastures right now (late April) are 14-20 percent protein; the dry grass that our ewes graze in July and August are 4-6 percent protein.
On the demand side of the equation, our forage demand (both in terms of quality and quantity) peaks as our ewes give birth and nurse their lambs. Non-lactating ewes have much lower feed demands - that's why we can graze them on dry annual grass in mid-summer. Growing lambs, on the other hand, need the most nutritious forage we can provide - they need energy and protein to grow muscle, bone, fat, and wool. Since we wean our lambs in mid-June at 65-70 pounds, this means that any lambs we plan to keep and finish on grass (at 100-110 pounds) need the highest quality forage we can grow. And we have a second (albeit) lower peak in nutritional demand in September, when we bring our ewes back to irrigated pasture to get them ready for breeding season.
Regardless of the forage type (green or dry rangeland forage or irrigated forage), we boil the considerations I've outlined into an estimate of sheep days per acre. This is sheepherder talk for estimating how many sheep one acre of forage will support for one day (cattle producers can do the same kind of estimate - one cow day's worth of forage will feed 5-6 sheep!).
Last summer, we grew (and harvested with sheep) just over 18,000 sheep days of irrigated pasture forage. If we divide this number by the days in our irrigation season (180 days, to keep the math simple), we see that we can graze 100 head of sheep on our pasture for the duration of the irrigation season. Let's break this down a bit further:
- From April 15 to June 15, we grazed 80 lactating ewes, 10 replacement ewes, and 110 lambs on our irrigated pasture. Based on how much each of these classes of animals consume, we estimate that we harvested about 9,000 sheep days in that two-month period.
- Once we weaned the lambs, we sold all but 35 of them (the sheep we kept included 20 replacement ewe lambs and 15 feeder lambs that we wanted to finish on grass). These sheep remained on irrigated pasture from June 15 through August 31 (for our purposes, let's say 75 days). These sheep consumed 2,625 sheep days worth of forage.
- From September 1 through the end of irrigation season on October 15, we had all of our sheep (ewes, replacement ewe lambs, and feeder lambs) on irrigated pasture - a total of 120 head. During this period, we harvested another 5,400 sheep days of forage.
- After the end of irrigation season, we had approximately 975 sheep days of forage left - with 120 head of sheep in our flock, this meant we had just over 8 days of grazing left on our irrigated pasture after the water turned off.
So how did a blog post about selling meat end up looking at grazing math?! Let's say that we wanted to direct market more lamb as individual cuts of meat (that is, finished and processed lamb). For example, what if we wanted to finish and direct market 75 lambs - could we do it with our current forage resources? From June 15 through the end of irrigation season, these 75 lambs would require 9,000 sheep days of our best forage. Since we'd already used 9,000 sheep days up to June 15, these lambs would require every blade of grass we could grow after weaning. We would have no grass for growing ewe lambs, nor would we have any grass for our breeding ewes. Our alternatives would be to purchase hay, lease additional irrigated pasture, or reduce the size of our breeding flock. We couldn't simply wake up on June 15 (weaning day) and decide to keep 60 extra lambs because we wanted to sell meat next November instead of feeder lambs next week.
The last issue for me is the added time and cost involved in marketing meat. In a good year, I know I can sell our feeder lambs in late June for $130-150 per head. If I decide to finish them and sell them as meat, I will incur additional costs beyond the cost of feeding these lambs for another 4-5 months. Once they're finished, it will cost me about $150 per lamb to have them harvested and packaged in a form that I can legally sell. I'll have multiple trips to the processor (which take me away from doing work on the ranch). I'll have the time involved in marketing and selling meat (which can be significant). I'll have the cost involved in storing meat. At our scale, I've found that selling meat results in higher gross income, but selling feeder lambs in June results in higher net income. In other words, we're more profitable selling a live feeder lamb in June that we would be selling meat in November.

Given California's ongoing shelter at home order, in response to the COVID-19 crisis, most of the ranchers I know are no longer gathering at a local coffee shop to catch up on how the neighbor's calf crop looks! Thanks to the wonders of modern technology, however, I held my first-ever Virtual Coffee Hour for ranchers this morning! We had a great discussion about drought, wildfire preparation, the impacts of COVID-19, and our individual coffee preferences.
Our conversation confirmed that this has been an exceptionally unusual year in terms of forage growth. Some noted that there seemed to be more foxtail and filaree than usual; others said the forage growth was patchy. Everyone felt like the forage on our annual grasslands would mature earlier than usual - possibly signaling an early onset of fire season.
Most importantly, we learned that 60 percent of those on the call prefer black coffee, while 30 percent add cream and sugar. And an astounding 10 percent didn't drink coffee at all!
Our next Ranchers Virtual Coffee Hour will be on Tuesday, May 5 at 6:30 a.m. - register here to get a link:

If you're like me, you were probably surprised to look at the calendar this morning and realize that irrigation season begins in here in the Sierra foothills this week. With all that has been happening in our world (sheltering at home, socially distancing, washing my hands constantly), April 15 sneaked up on me this year. Nevertheless, the Nevada Irrigation District will begin delivering summer water in two days - I guess I'd better get ready for it!
I'm sure many of you are well ahead of me in terms of your preparations. You've probably cleaned out ditches, flushed mainlines, and checked sprinklers (depending on how you irrigate your pastures). We use a K-Line pod system for our small pasture near Auburn, so I'll spend Wednesday morning flushing lines and replacing broken sprinklers. I'll also lay out stakes with flags at the end of each set; our K-Line system is designed to run on 24-hour sets and a 12-day rotation. I'll start just about every day for the next six months dragging K-Line pods across our pasture.
If you plan to fertilize your pasture, now is the time to apply nitrogen. For a more comprehensive look at pasture fertilization, read "To Fertilize or Not to Fertilize" in my April 2020 newsletter. Here are the key points when it comes to applying nitrogen:
- Take species composition, water availability, and irrigation uniformity into account. Don't apply fertilizer if the pasture does not have adequate soil moisture at the time of fertilizer application nor if irrigation or rainfall are not possible in the near future.
- Consider collecting a nitrate soil test in the spring and fall. It's easy to collect, costs less than $20 per sample, and is a good way to see if fertilizer is needed shortly before application. It also allows you to develop a history of soil nitrate in your pastures, which will allow you to see trends. In the future, you may want to sample below the root zone to see if N is accumulating below the root zone and alter your irrigation management accordingly.
- Most irrigated perennial cool-season grass pastures will benefit from the application of 80-100 lbs. of nitrogen per acre applied in the springtime. It's not worth putting out less than 50 lbs. per acre – the application costs will be the same, but the boost in production will be lower.
- Don't apply N when establishing a new pasture – you'll only boost weed growth. Seedling grasses need more frequent irrigation then established grass. They can benefit from nitrogen after the seedling growth stage but only if weeds are not a problem or weeds are controlled with herbicides. Wait until the planted species have germinated and started growing before applying nitrogen.
Finally, don't neglect grazing management. Proper grazing management can greatly enhance forage production. Allowing forage to re-grow after it's been grazed (and before it's grazed again) will stimulate root growth and increase overall production. Avoid irrigating underneath your livestock - this will reduce the potential for soil compaction and will help protect water quality. Remember the 5 principles of managed grazing:
- Adjust your pasture rest periods to the growth rate of the plants. Our cool-season forage species will grow rapidly in the spring and fall; they'll go through a summer slump in hottest months. We can get by with shorter rest periods during times of rapid growth; we'll need to provide longer rest in July and August.
- Use the shortest graze period possible while maintaining adequate rest. We can make more efficient use of forage by using shorter graze periods - livestock will graze more if they're frequently going onto fresh feed.
- Use the higest stock density possible. Stock density will improve uniformity of grazing.
- Use the largest herd size possible consistent with sound animal husbandry principles. Fewer herds or groups of animals can simplify management considerations. Larger herd size also allows us to optimize beneficial impacts from hoof action and manure/urine deposition.
- Adjust stocking rate to seasonal changes in carrying capacity. During the spring flush and fall rebound, forage production can be substantially higher than during the hottest part of the summer. Some producers adjust to this seasonal fluctuation by harvesting hay. In our sheep operation, we use the spring flush to feed lactating ewes and growing lambs. As productivity decreases with warmer temperatures, we reduce our stocking rate by only grazing our replacement ewe lambs on our irrigated pasture. Come fall, when we're putting the ewes on a higher plane of nutrition in anticipation of breeding, we increase our stocking rate as forage productivity increases.
