Cow and Heifer Slaughter Still Strong but Declining

By Derrell S. Peel

Heifer slaughter remained strong in the first half of 2023 but does show signs of declining going forward.  For the first half of the year, total heifer slaughter was down 0.5 percent year over year with a decrease of over four percent in the month of June. The July Cattle report will be released by USDA on July 21 and the industry is looking to see if there are any indications that herd liquidation has ended, and herd rebuilding might begin.  The report is expected to show that herd liquidation continued in the first six months of the year but may slow in the remainder of the year.  There is no data currently to support the idea that heifer retention is underway but it may have started with recent improvements in range and pasture conditions.  The beef replacement heifer number in the upcoming report will be of keen interest and is likely to show a still smaller number compared to last year but could show a slight increase year over year if heifer retention has begun.

The cattle inventory report will show that the beef cow herd continued to decline in the first half of the year.  While beef cow slaughter is down thus far…down 12.0 percent year over year in the first six months of the year…the current pace suggests a herd culling rate over 12 percent for the year.  Beef herd expansion requires a herd culling rate below ten percent and likely below nine percent for a year or more.  Beef cow slaughter is likely to decrease more significantly in the second half of the year but is unlikely to drop enough to come close to stabilizing the beef cow herd this year. Total cow plus heifer slaughter through June averaged 51.8 percent of total cattle slaughter.  This percentage indicates continuing herd liquidation.  Total female slaughter will drop below 45 percent of total slaughter during active herd expansion.  This is unlikely to happen before 2024 at least.

The July Cattle report is expected to show that herd liquidation continued in the first half of the year.  The report is unlikely to show definitive signs of strong heifer retention but could indicate the beginning of retention if the beef heifer inventory is down just slightly or possibly even up slightly.   The monthly Cattle on Feed report released the same day will also include a quarterly breakdown of steers and heifers in feedlots.  The number of heifers on feed decreased modestly compared to last year in the January and April data but a sharper decline in the number of heifers in feedlots in this July report would be the first significant data indication of heifer retention.  In short, the upcoming reports are unlikely to show that herd liquidation has stopped but might provide indications that the situation will begin to stabilize in the remainder of the year.

Challenging Times for Growth Promoting Implant Use

Paul Beck, Oklahoma State University, Extension Beef Cattle Nutrition Specialist

The U. S. Beef industry has used anabolic implants since the mid 50’s when Synovex-S was approved for use in growing cattle. The artificial equivalent to testosterone, trenbolone acetate (TBA), combined with estrogen like compounds has been in use since the late 80’s. The U. S. Food and Drug Administration (FDA) approved implants in use today as efficacious and safe for beef cattle production. There has never been a substantiated adverse event for humans since approval in 1956. All implants are approved for no withdrawal before slaughter, emphasizing their safety.

Label changes, effective July 1, 2023, make reimplanting within a production phase off-label use of implants unless the label specifically states it is approved for reimplanting.

What are the stages of production?

There are currently 3:

1. “Beef calves 2 months of age and older” – defined by FDA as “Beef calves considered ruminating and nursing their dams from 2 months of age to weaning.” The FDA states: “While there are cattle ear implants approved for use in this production phase, no implants are approved for use in a reimplantation program in this production phase of cattle.”

2. “Growing Beef Steers and Heifers on Pasture (stocker, feeder, and slaughter)” – FDA defines as “Weaned growing beef steers and heifers … intended only for slaughter (i.e., not for reproductive purposes) maintained on pasture and receiving the majority of their diet from grazing." The FDA also states: “While there are cattle ear implants approved for use in this production phase, no implants are currently approved for use in a reimplantation program in this production phase of cattle. Cattle in this production phase may only receive one implant during this production phase regardless of whether they are considered part of the subclasses “stocker”, “feeder”, or “slaughter”.”

3. “Growing Beef Steers and Heifers Fed in Confinement for Slaughter”– further defined as “Weaned growing and finishing beef steers and heifers (beef and dairy breeds) intended only for slaughter (i.e., not for reproductive purposes) and confined in group pens and fed a progressively high-energy diet ad libitum as their sole ration until slaughter... Includes growing beef steers and heifers in a grow yard.“
