BioPro Rumen and Herd Health

The ingredients in BioPro have been formulated to be very effective in stimulating more efficient digestion of feed and maintaining herd health. Long term users consistently report improved herd health, increased feed efficiencies and consistent production on the BioPro program.


There is now strong anecdotal evidence from long term use and professional autopsies that are also showing strong physical rumen health being maintained, even in very high grain fed diets.


During an autopsy on a Dorrigo cow from a herd that had been fed BioPro probiotics for some years, the attending vet commented on the visibly impressive state of the rumen.

Following this, four further autopsies were commissioned on cull animals to investigate & confirm this observation, two in Tasmania and two in Queensland.



"Her extensive Rumen Papillae condition is worth noting, considering she was a very high grain fed cow."

1st Autopsy Tasmania


Lindsay Thompson

Bracknell Tasmania

Report prepared and autopsy performed by,

Dr David Nolan (BVSc.)

Meander Valley Veterinary Service

In May 2016 a post mortem was performed on a cow at Lindsay Thompson's farm in Bracknell, Tasmania to inspect the rumen health and GI tract condition.

Lindsay had been on the full BioPro program for approximately 3 years, he removed the sodium bicarb and antibiotic based buffers on starting on the the full BioPro Probiotics program he has ben extremely happy with all parameters, the springers, ease of calving, production, herd health, cell count, feed conversion and fertility, in Lindsays own words; "I would not feed dairy cattle without this product because of the level of herd health and consistent production we have seen since starting on this program".

Dr Nolan quoted in his autopsy report; "On gross examination at post mortem, this cow's rumen appeared extremely healthy with an extensive population of well developed, long ruminal papillae as well as a thick internal rumen wall. Anecdotal reports and the post mortem results suggest that these probiotic products are having a beneficial effect on cow health, nutrition and performance. Increased case investigations and scientific data would add weight to these ideas; however these local results and findings are quite promising" Dr David Nolan (BVSc.)

"The development and renewal of rumen papillae depends on adequate nutrient intake.  Furthermore the intake of protein and energy-rich feed promotes the growth of rumen tissue, increases the number and size of rumen papillae and enhances the absorption of short chained fatty acids from the rumen of cows" (Shen et al 2003)"

After the autopsy on Lindsay Thompsons farm, another was performed by Dr Nolan twelve months later on Jamie Berne’s Farm, comments are added below.

2nd Autopsy Tasmania


Jamie Berne Autopsy

Report prepared and autopsy performed by,

Dr Dave Nolan (BVSc.) 

Meander Valley Veterinary Service

This autopsy was performed on an older cow that had been bail fed, on average, nine kilos of concentrate daily since first lactation. During her first year on the BioPro program she produced over 14,810 L of milk, up from 12,595 L the previous year.

After losing a quarter earlier in the current lactation, this cow was due to be culled. The BioPro team purchased the cow to cull for scientific purposes. At the time of autopsy and only 6 weeks prior to herd dry off, she was still producing 36L of milk from only three quarters.


Her extensive Ruminal papillae condition is worth noting, considering she was a pasture based, high grain, bail fed cow, with only the BioPro lactating herd product formulated into her grain for the last two years, with no sodium bicarb or chemical based Rumen enhancers added. This herd has shown no signs of the usual high grain feeding issues suffered in bail fed, pasture based herds. Since converting over to the full BioPro Program Jamie has commented on the improved feed conversion efficiency he is seeing.

"On gross examination at post mortem, this cow's rumen appeared extremely healthy with an extensive population of well-developed, long ruminal papillae as well as a thick internal rumen wall".

Direct quote from Dr Nolan (BVSc.) autopsy report.

This farm showed year on year consistency in both production and herd health following the introduction of the BioPro program. Jamie is extremely impressed with all parameters including the springers, ease of calving, production, herd health, cell count, feed conversion and fertility. 

Other farms from around Australia are reporting similar results, particularly through the second year.

Local SE Qld vet Dr Robyn Plunkett (BVSc.) has also performed two autopsies in Qld to back up Dr Nolan’s findings from the two Tasmanian autopsies.


After dairying with her husband for close to thirty years and realising the need to reduce antibiotic usage on farms, she was impressed to see the results of the autopsies, especially when considering the amount of grain fed and the BioPro Probiotic DFM included as the only rumen control agent.


This is a quality probiotic blend that has high levels of active ingredients. Ongoing research has shown quality probiotics not only improve feed conversion efficiency, but also promote herd health.  We now have strong physical evidence of a very healthy rumen wall being maintained even in high grain fed cows, as evidenced by the 5 autopsies performed on cull animals from long term users on the BioPro program,” Dr Robyn said.

A strong rumen wall, pappilae health and lower gi tract health is paramount for not only herd health but efficent absorption of nutrients.

Preventative medicine is an exciting and developing field in the intensive animal industries. With products like BioPro probiotics providing a viable, natural alternative for dairy farmers, not only is money being shown to be saved on vet bills, but money can be saved if you take into account time, lost production and treatment costs saved when herd health parameters are maintained
