Choosing the synchronization protocol that best fits each individual situation is challenging because so many options are currently available.
Despite our best efforts at bull selection and heifer development, cows or heifers occasionally need assistance at calving time. Every baby calf has a certain degree of respiratory acidosis.
Calves born after a prolonged, difficult birth are at a high risk of failing to receive adequate colostrum by natural suckling because of greatly decreased colostrum intake.
As the spring calving season begins, beef cows will show typical signs that will indicate to the rancher that parturition is imminent.
Many spring calving herds will begin calving around the first of February, if not before, so an increased understanding of the “calving” or parturition process is helpful.
Cull beef cows represent 10% of the beef consumed in the U.S. and they represent 20% of the gross income of commercial ranches, making proper cull cow management important.
Christmas Eve day on our Platte Valley farm was cloudy and cool. Evening chores were to be completed earlier than usual so that the family could attend Christmas Eve services at the small Presbyterian church in town.
The easiest and most practical method of inhibiting nighttime calving at present is by feeding cows at night. Several studies have confirmed what one Canadian rancher observed in the 1970s.
Southern plains ranchers often use wheat pasture as much of the winter feed supply, but some may wonder about unsatisfactory breeding performance of heifers when grazing wheat pasture.
It is not too soon to begin to prepare for the spring calving season. Locating, obtaining, and storing several doses of colostrum or colostrum replacer will come in handy before the first heifers start to go into labor.
Preparing ahead for next spring’s calving season can help increase the chances of success and there are several key steps that would be good to conduct in November or December.
Estimating forage usage by cows is an important part of the task of calculating winter feed needs. Hay or standing forage intake must be estimated in order to make the calculations.
Body condition changes from the time the cow calves until she begins the breeding season and can play a significant role in the rebreeding success story.
Meeting the supplemental protein needs for the cows and replacement heifers consuming that forage must be done properly and economically.
Cull cows represent about 20% of the gross income in commercial cow calf operations. Understanding the major factors impacting cull cow prices is important to your bottom line.
