Below are a few tips to consider stretching limited hay supplies. For additional information contact your local Extension agent. It is recommended to consult with your feed nutritionist or County ANR Agent before making drastic changes in your feeding program.
- Inventory hay – know how much hay you have available; weigh a few bales to get an average weight or estimate the weights based on available information from Extension publications.
- Minimize storage losses – keep hay off the ground on a surface that will allow water to drain away; keep bales covered or stored inside a barn; if bale grazing limit the number of bales placed in the field to provide 2-4 weeks of feeding to reduce weathering losses.
- Reduce feeding loss – consider minimizing feeding losses; using hay rings with skirts / metal on the bottom, tapered ring designs, chains to suspend bales, or cone inserts to keep hay inside the feeder has been proven to reduce hay feeding losses compared to hay rings with openings at the bottom; using an electrified temporary poly-wire placed down the center of unrolled hay will reduce losses from cows laying on the hay, trampling it into the mud, and defecating on the hay; feeding processed hay into a bunk or large industrial tire reduces waste compared to feeding processed hay on the ground.
- Cull – consider selling less productive females, open cows, and cows with structural/functional issues to reduce the number you must over winter; consider selling the bull as the market may provide the opportunity to sell a mature bull and replace him with a younger bull next spring.
- Limit time access to hay – research has shown dry cows in mid-gestation can be maintained on good quality hay when they have restricted access time to only 6-8 hours a day; the hay savings comes from less waste as feeding behavior is altered; all cows must be able to access hay at any given time; this is not recommended young or thin cows, lactating cows or growing animals.
- Substitute hay with grain – calories and protein can be provided from supplements; grain/commodity mixes can be used to replace hay; cows can be maintained on a low hay diet by using grain supplementation that balances the nutrient supply and animal requirements; consult a nutritionist before making extreme feeding changes.
- Deworm young animals – animals with an internal parasite burden will have reduced efficiency.
- Feed an ionophore – if grain supplementation will be used, consider adding an ionophore to increase the energy efficiency of the feed consumed. Consult your nutritionist to discuss inclusion rates and developing a supplement program. Previous work has shown that feeding 200 mg of monensin allowed cows to maintain body condition on 10-15% less hay.
The optimal time for making a first cutting of forages is fast approaching. But what is the optimal timing to take the first cutting (or any cutting for that matter)? Many will answer by saying it is when you have time and there is a good weather window to get the forage cut and put up! Yes indeed, that is a valid answer. Both of those factors are important and can’t be ignored. However, we know that forage quality declines as the crop moves into flowering stages. The first cutting is usually the highest yielding cutting, so we should try to aim for good quality for as much of it as possible!

Potato leafhopper (PLH) adults arrived in Ohio during the last week of June and first week of July. Since then, the eggs have hatched and we are now seeing late stage nymphs and adults infesting alfalfa fields. A few fields are showing the typical “hopperburn”, which is a triangular yellowing from the center of the leaf to the leaf margin. The more mature the crop of alfalfa is since the last cutting, the more the hopperburn symptoms will be showing. Hopperburn will also become more pronounced in areas of the state that are short on rain or are predicted to become drier because the alfalfa will not be able to outgrow the feeding activity of PLH. Scouting now and making appropriate management decisions based on the scouting can help avoid serious damage to the crop. 
The rainy weather in many regions of Ohio and surrounding states is making it difficult to harvest hay crops. We usually wait for a clear forecast before cutting hay, and with good reason because hay does not dry in the rain! Cutting hay is certainly a gamble but waiting for the perfect stretch of weather can end up costing us through large reductions in forage quality as the crop matures.
Hay and haylage crops are grown on just over 1 million acres in Ohio (NASS, 2019) and are grown on more Ohio farms (44% of all farms) than any other crop (Becot et al., 2020). In addition, there are over 1.3 million acres of pastureland on nearly 39,000 farms (50% of all farms) in the state of Ohio (NASS, 2017). Fertilizer costs represent 40 to 60% of the variable input costs of forage hay production (Ward et al., 2016, 2018), and so managing these costs is key to an Ohio forage producers’ ability to stay competitive. Furthermore, water quality issues in the state underscore the need for Ohio farmers to manage on-farm nutrients as efficiently as possible. A farmer’s ability to find this optimal balance between meeting crop nutrient requirements without over-application is highly reliant on the best available information.
