Noxious Weed Control in Pasture and Range

Noxious weed control in pastures is becoming more of a challenge. Most ground commercial spray businesses are no longer spraying pastures.

Water Importance in Lactating Dairy Cows

When considering the importance of water in lactating cow diets, we need to remember that milk is 87 percent water, and its consumption is directly correlated with milk production and feed intake. Water also makes up anywhere from 55 percent to 70 percent of the body weight of a lactating dairy cow, depending upon the phase of the lactation cycle.

Spot Treatment Options for State Noxious Plants

When controlling grassland weeds, the mindset of row crop weed control may be put into practice too often. In most cases, broadcast control of weeds in grasslands is rarely necessary. Most often, spot treatment can be used more effectively to manage the noxious and invading weeds.

Planning for a Muddy Breeding Season

Early calving spring cow herds have wrapped up calving and are preparing for breeding season. If you are having flashbacks to breeding in the mud of 2018, try approaching this year with an open mind and review breeding season protocols with a “mud” backup plan.
