Any more, I just say 'bred' or 'open'. From about 45 days to 3-4 months I feel reasonably comfortable giving an estimated time... but beyond that, it's a guess (at least for me), that I'm not inclined to make. Couple of years back, I was checking cows for our kids... I called one 5-6 months...

Yeah, well, we had to have C-sections for all four, so it's probably best that we went, or I'd have been a widower, like in days of old.

My wife(she's a vet, too) and I had been out to pull a calf when she was 9 months pregnant. Got home, and she was showering off... hollered to me... "The water broke!"... I though something had broken in the bathroom... "No. MY water broke!" So... off to the hospital for our firstborn delivery.

I always kept at least 10 lbs of white, granulated sugar on the practice truck for use on those uterine prolapses.

Saw plenty of stillborn calves with full urinary bladders. I wouldn't attach any significance to 'peeing' as a sign of having nursed.

That 6 months is a 'best-case' scenario. If you're in a heavy-pressure Lepto area, you might even need to booster every 3-4 months.

Here in western KY, with that presentation, Neospora would be Candidate #1, 2, and maybe #3. Lots of coyotes and roaming dogs. Over 25 years in the diagnostic lab here, I could count on one hand the number of confirmed Lepto abortions I saw. But... feral hogs are not (yet) a significant issue...

We generally consider that cows & heifers can 'clear' the infection within 3-6 months, but most infected bulls are infected 'for life' due to the Tritrichomonas organism colonizing epithelial crypts in the prepuce... though it appears that some young bulls may be able to 'clear' on their own...

The proposed connection between phytoestrogens from legumes and multiple births in cattle is shaky, at best. Most of that work was done with sheep, and it doesn't necessarily carry over to cattle. Plant breeders have reduced phytoestrogen precursors in most Trifolium clover varieties on the...

That smaller calf is pretty nasty behind...makes me wonder if her debilitated state, associated with her respiratory disease didn't also set the stage for some significant GI tract damage due to coccidia.

Here's my take: Four (commercial?) crossbred heifers. If the bull has no KNOWN genetic defects, based on his pedigree, the likelihood of him siring defective calves out of his own daughters is infintesimally small. If you like him and what he brings to the table, you'll just be concentrating...

Jeanne touched on the 'extra' white you might get with a WF Simmental over WF cows... and she's right, but in my experience, you can't count on the white face in Simmentals to transmit as reliably as the Hereford white face. Last few Simmental AI sires we used were black whiteface or...

As I stated earlier, most abortion diagnostic workups fail to determine a definitive cause of abortion - but they do 'rule out' many of the things that you, as a producer, can influence - vaccination, mineral supplementation, testing forages for excessive nitrates, etc. If I was only allowed...

A full diagnostic workup on that aborted fetus & placenta - with accompanying acute & convalescent (3 wks later) serum samples from the dam would come closer to giving a diagnosis and whether it's a potential 'herd problem'. That said, over 30 years of doing diagnostic veterinary pathology, I'd...

I've done it - and would do it again. In a commercial herd, I'm of the opinion that, if you like the bull and what he brings to the table, why not extend his useful life by using him for more than 2-3 years, AND concentrate those desirable traits in his offspring. Nobody buying a...

Subfertile...I think 1 in 10 is high. Sterile... much lower. I can count on 2 fingers the number of cows we raised in 40 years that I would classify as having been 'sterile'.

Calf survivability in adverse conditions.... look at dam's level of nutrition, particularly in the last trimester. Inadequate dietary protein intake will result in calves that have difficulty generating body heat, getting on their feet, and nursing. Add to that, colostrum quality may be...

One particular Angus sire we used, years ago... his calves were a threat to get up and haul @ss if you startled them... one crossed four fencelines and a paved road. After dealing with those wild-@ss little b@st@rds, we decided... unless they were still wet and hadn't yet gotten to their...

Simme, I was trained to to BSEs while in vet school and did quite a few while I was in practice. My last 28 years were spent in a veterinary diagnostic lab setting, and we did semen evaluations - though only one local practice was close enough to bring fresh-collected samples for examination...

Only two ways this can work: 1) Cow is not yellow. She is essentially a black cow with color dilution or/and color inhibition gene altering expression of the black gene. That, or 2) the sire is not the Hereford bull, but, rather, a black-hided 'visitor'. Had a couple like her.. half Angus, out...
