The Economics of AI Breeding vs. Natural Breeding in Beef Heifers

Suggested Guidelines for Beef Heifer Selection

**Moderate frame & milk - 425 lbs at Weaning, 600 lbs at Yearling, 700 lbs at breeding, Frame Score of 4
**Large frame & milk - 500 lbs at Weaning, 750 lbs at Yearling, 875 lbs at breeding, Frame Score of 5

"The University of Minnesota maintained records and summarized the net profit or loss for heifers sold during a developmental period during a three-year period. Heifers culled on the basis of pelvic area, average daily gain, reproductive tract scores, disposition, or structural soundness at the time of the prebreeding exams and finished in a feedlot had a 3-year average net profit of $9, whereas heifers diagnosed as nonpregnant shortly after the breeding season were sold for a net loss of $86. The loss for pregnant heifers that were then diagnosed nonpregnant after wintering on native pasture and sold at a sale barn was $133."


"These figures indicate the importance of identifying heifers that will not breed during the breeding season and culling those heifers before they become an economic liability. Heifers that were diagnosed pregnant during the breeding season were allocated to three groups: first-service AI, second-service AI, or natural mating. Average profits were $163 for first-service AI heifers, $139 for second-service heifers, and $83 for heifers naturally mated. These figures take into account all synchronization costs."

"Therefore, the advantage of AI over natural mating is certainly evident from these analyses, but without sound data these results could not have been noticed. In fact, many people would (and still do) shy away from AI because of the initial costs associated with synchronization, management, and an AI technician. Nonetheless, these results would encourage a producer to seriously consider AI, realizing that the profit potential is far greater than just using natural mating.

Tom Sawyer Bull Calf born to Wanda Mae

A wonderul British White cow is my Wanda Mae. She was one of my original heifers and she was nicknamed for a childhood friend who wasn't the most popular or the most beautiful girl in my neighborhood - she was more importantly the most trusted. Wanda Mae gladly took in my Midge doll for safe keeping forever and always when a very bad lady was going to throw her away. I will always remember her fondly for taking care of my Midge.

My cow, Wanda Mae, is as equally unforgettable as my childhood friend. Wanda Mae is a fertile myrtle, a feed efficient femme fatale, a carcass queen, and the most gentle British White cow I've ever encountered in any herd in the USA or the United Kingdom. Why am I talking about Wanda Mae this evening? Well she gave me a surprise Sunday morning. A bouncing bull calf was mewling and hobbling around and announcing his brave entry into his new world.

I had noticed Wanda Mae looked like she was putting milk on, but she keeps a nice udder in between calves, and she stays fat, and with her deep well sprung rib area she always is mistaken for being pregnant by visitors when she's not! But I poked her udder and squeezed the nipples about a week before, wondering just what was going on. Nonetheless, I was surprised.


Fortunately, I make a habit of recording when any bull jumps a fence, plows through a fence, or seems to magically fly over a fence. In this case, it was Tom Sawyer who was the culprit, and sure enough Wanda Mae is one of three cows jotted down as possibly cycling when he made his pasture break to the girls.

Follow this link for a very short video of this handsome Tom Sawyer sired bull calf. He measured 27.5 inches, which puts him weighing about 67 pounds at birth. The video is from this afternoon, and he is now three days old. Most three day old calves in other breeds will absolutely not let you fool with them. This little guy is above and beyond friendly. I couldn't take a single stretch of video that didn't find him walking straight to me and my camera.

In this clip at the very end his Dam, Wanda Mae, puts her nose right in my camera as well. That's gentle. Make no mistake that the British White breed is truly gentle; from the day they hit the ground they have a God-given curious and friendly nature, or not.

BeefTalk: There Is No Profit From Calves That Cost $2.80 Per Pound?

I found this article of great interest. There is NO mention of the breed of bull chosen to cover these 26 heifers. However, great care was given to selection in terms of documented EPD's, and this bull's numbers fell in the sought after top percentile for key EPD's.

Despite this, the Dickinson Center had a miserable ~30% dead or difficult calving percentage. That costs money, not just the $2.80 a pound ceasarian births, but the assists, and the deaths, as well. Such calving results are virtually unheard of in any British White herd of cattle. And we certainly don't have to worry about 'ornery' heifers that want to hurt us -- another potentially costly event.

In today's economic environment cattle producers should start thinking more about the costs of these 2000 pound plus high pedigree, drowning in EPD's bulls. The cost of their potentially big calves born, or not born, successfully to heifers, is not a cost any small producer can bear.

The British White breed is small in numbers, we do not have sophisticated EPD's for use in choosing sires and dams -- but do we really need them to add value to our breed? I don't think so. The British White breed naturally puts low birth weight calves on the ground that grow off with vigor, fatten well on grain or grass, and grade 80% plus choice and better under traditional feedlot production.

EXCERPTS OF THIS ARTICLE:

"The Dickinson Research Extension Center started calving with mixed results. The weather has not been horrendous and the first-calf heifers are up close. the first calf born, however, was dead. The feeling of seeing the desire and efforts of a cow that wants to be a mother and is licking and nudging her dead calf is not good.

The second heifer was calving and having difficulty, so life moves on. The birth was assisted, but she ended up with a 96-pound calf. However, the heifer was belligerent and ornery. Her intent on inflicting damage to us or the calf was obvious, so out of the pen she went. She will spend her remaining days with us in the feedlot, but with us out of her reach.

Fortunately, heifer 7037 was still looking for a calf and adopted the calf with no questions asked. Sometimes things actually do work out.

The center has tried to keep birth weights low and calving ease high when selecting bulls for heifers. This year's sire of the calves was listed in the top 15 percent of the breed for calving ease and the top 45 percent of the breed for birth weight (the smaller birth weight expected progeny differences (EPD), the better).

The bull was a high-growth bull that is in the upper 15 percent of the breed for weaning weight, upper 10 percent for yearling weight and has very good carcass EPD values. The bull is a good bull, but is he a heifer bull?

In this case, the four calves that had difficult pulls or cesarean sections have averaged 84.5 pounds. Out of 26 heifers, we have lost three calves and assisted five births (one light assist). of the dead calves, two were born dead and the third was a cesarean section. Of the four difficult assisted births (other than the cesarean section), they are doing fine, but had big calves.

The four calves that needed assistance averaged 98 pounds and ranged from 92

to118 pounds. Of the 21 heifers that had no birthing problems, their calves averaged 82 pounds at birth and are doing fine.

Although hard to document, when a set of calving heifers are slow to recoup after calving and the calves are cumbersome at best, you should know you are pushing the envelope. We pushed the limits and created a manageable, but difficult situation.

Is the return for the added performance of the calves worthwhile? We will wait and see, but I can tell you it costs $2.80 a pound to produce a calf through cesarean section. There is no profit from calves that cost $2.80 per pound and have no heartbeat."
