Matching Milk Production and Cow Size to Resources

Matching Milk Production and Cow Size to Resources

Producers tend to pay attention to cow weight, but new research suggests that milk production by the cow is also worthy of attention.

Cow weight is probably easier to wrap your mind around than milk production, but research has shown that cows with the genetic propensity to milk heavily require more nutrients year round, not just when they are milking.

Using Live Animal Carcass Ultrasound in Beef Cattle

Using Live Animal Carcass Ultrasound in Beef Cattle

Carole H. Brannen

Extension Animal Scientist – Beef Cattle, University of Georgia

The beef industry has begun using a value-based marketing system, where cattlemen are rewarded for producing a high quality, consistent end-product that meets the demands of consumers. One tool that aids producers in the efficient and profitable production of beef cattle is live animal carcass ultrasound. The use of carcass ultrasound is an economical way cattlemen can make genetic improvements in carcass traits, which will, in turn, put profits in their pockets.

Lice Control In Cattle

Lice Control In Cattle

Lee Townsend, extension entomologist

Southern Livestock

Lice are small, flat-bodied insects with legs modified for grasping hairs. They cannot survive off of the animal for more than a few days. Sucking lice, with their narrow, pointed heads, are blood feeders. Biting lice feed by scraping material from the skin and base of the hairs. The eggs, or nits, of both types are glued singly to hairs and hatch in about two weeks. The nymphs, or immature stages, resemble the adults but are smaller. They mature in about three weeks. Adults live two to three weeks and females lay about one egg per day.

What is Winter Tetany?

Winter tetany is a metabolic condition caused by lower than average blood magnesium (Mg) levels. This condition occurs when cattle consume poor quality hay or straw, that contain low levels of magnesium, or good quality cereal greenfeed or silage with high levels of potassium (K).

Q&A: How does a person figure how much corn to buy to finish out a 600 lb steer? ADG will be 3.5 lbs. Is there a ratio or rule of thumb to follow when figuring out how corn to buy?

Q&A:   How does a person figure how much corn to buy to finish out a 600 lb steer? ADG will be 3.5 lbs. Is there a ratio or rule of thumb to follow when figuring out how corn to buy?

Dr. Galen Erickson, Associate Professor of Animal Science, Animal Science, University of Nebraska

A:   The old “rule of thumb” was 50 bushels per head for yearling cattle. As it turns out, that is not far off, but can be refined.

The main determinant will be feed conversion (which is fairly predictable within a range anyway) and what other components are fed.
