1) Know and track Income Over Feed Cost (IOFC) and Income Over Purchased Feed Cost (IOPurFC) Income over feed cost (milk revenue minus feed cost) is more correlated with overall farm profitability than any other single metric and can be refined further to look specifically at Income Over Purchased Feed Cost. In analyses of feeding programs conducted as part of PRO-DAIRY discussion groups, income over total feed cost varied as much as $3.00 per cow per day, even across well-managed herds.
In our last analysis, herds with higher IOFC had:
- Higher fat and protein yield per cow (generally over 6.0 lbs/day of fat and protein shipped)
- Higher feed efficiency (over 1.65 lbs of ECM1 per lb of DMI) across the lactating cows
- Higher feed cost per cow per day (cows were making more milk and so had higher DMI)
- Slightly higher cost per lb of TMR dry matter — $0.137 vs $0.132 per lb
- Optimized use of forages (0.9 to 1.0% of cow body weight as forage NDF intake) Income over total and purchased feed cost as well as feed efficiency can be calculated and tracked using spreadsheets or calculated using the Dairy Profit Monitor online program developed by PRO-DAIRY.
1 Energy-corrected milk = (0.327 × lb of milk) + (12.95 × lb of fat) + (7.65 × lb of true protein)
2) Make sure you are optimizing use of homegrown forages and feeds
3) Fine-tune your feeding management
Losses due to poor bunk and feeding management can be subtle but meaningful. Are you taking at least 6 inches (preferably 12 inches) of silage off of the face of bunk silos every day and ensuring that bunk faces are tight and leftover feed kept to a minimum? Have mixer wagons and other equipment used in feeding (e.g., tub grinders) been maintained so that they deliver consistent performance? Is feeding accuracy being monitored and shrink of ingredients being tracked? Is fresh feed available for cows upon return from the parlor and is it being pushed up regularly (i.e., every 2 to 3 hours). We recommend targeting 5% refusal rates for close-up cows (close-up refusal can be re-fed to far-off cows) and fresh cows, and targeting 2 to 3% refusal rates for high cow groups (refusal from fresh and high groups can be re-fed to late lactation cows).
4) Strategically review rations with your nutritionist
Now is a good time to review rations and ration strategy with your nutritionist and make strategic decisions about where to try to save cost without compromising herd performance. In addition to making sure that you are optimizing use of homegrown forages and feeds (see above), there may be opportunities to decrease amounts of rumen-degradable protein sources (e.g., canola meal, soybean meal) in the diet. Furthermore, laboratory assays are now commercially available that allow for feed suppliers to evaluate protein digestibility and undigestibility of protein ingredients. Overall, proteins based upon soy or canola look to have good overall digestibility and little variation among sources; however, distillers grains and animal proteins (e.g., blood meal) can vary greatly in their digestibility – some are excellent and some are poor.
We are hearing that some financial consultants are advising farms to remove all additives and higher value/higher cost nutrients from rations in order to save cost. Although we recognize the need to make sure that there is return on the feed investment, we think that these across-the-board types of sweeping recommendations are poor and likely stand more chance of hurting cash flow rather than helping cash flow.
Our recommended approach is to review rations and prioritize maintaining ration ingredients and feed additives that directly affect daily cash flow/income over feed cost by contributing to component yield/feed efficiency or are fed during very focused periods of the lactation cycle (i.e., close-up and fresh cows) with research-based evidence that they contribute to improved productivity and health. The long-term implications on production, health, and reproduction for not meeting the needs of the transition cow are large. For more discussion on these decisions and other management decisions, see the Making Decisions about New Technologies on the Dairy paper that was presented at the 2017 Cornell Nutrition Conference.
Finally, we suggest that calf nutrition should not be a place where farms seek to cut feeding rates or quality of milk replacer. Such apparent savings can be easily erased (and then some) by increased drug costs for treatment and calf morbidity/mortality with long-term impacts.
5) Carefully review cow and heifer inventories and needs
Are the right cows being milked? How many heifers do you need? This topic is covered in part in another recent PRO-DAIRY paper Ten Key Herd Management Opportunities on Dairy Farms During Low Margin Times (see Mar. 19 DairyBusiness Digital at DairyBusiness.com.) Overstocking of cows generally contributes to lower feed efficiency through negative effects on milk components and poorer rumen efficiency as a result of more aggressive feeding behavior and altered time budgets.
Are you compromising performance of the whole by continuing to milk cows that are not covering their feed and variable costs? Many farms have improved their reproductive performance significantly over the past few years, such that we have seen overall heifer numbers grow as a proportion of the lactating herd. Feed costs are a major portion of the cost of rearing heifers – are the goals of the farm such that every heifer needs to be raised? Should you give up more quickly on heifers (or cows) that are not getting pregnant and save that feed cost?
There are a number of excellent business management resources focused on the cost of replacement heifer programs and spreadsheets that allow evaluation of various aspects of the heifer enterprise that were developed by Jason Karzes and available at the PRO-DAIRY web site.
