Case Study

BioStart Ruminant™ Beef Cattle Programme

Ruminanthelps optimise rumen function to improve feed utilisation & nutrient conversion.

Ruminant Beef Stock Programme


At weaning Calves experience separation stress and environmental stress caused by the move from set stocking to strip grazing field crops. Calves are also drenched at weaning which adversely effects the rumen’s microbial populations and therefore rumen fermentation. Ruminant helps reduce the rumen microbe stress caused by these events and helps restore rumen microbial populations.



For fattening When introducing yearlings to a supplementary crop the make-up of the rumen microbe populations are required to change rapidly so stock can digest this new feed. Dose with Ruminant to help boost rumen microbial growth and thereby allow the rum en microbial populations to adapt rapidly and maintain feed utilisation to achieve weight targets.


All stock

At feed change The rumen microbe populations are required to change rapidly so stock can digest a new feed/supplementary crop and maintain feed utilisation and animal performance. This process of changing the microbe populations can take between 4 – 9 days under normal conditions. Introduce the supplementary crop over a few days (seek advice by crop e.g. NZ Dairy recommend transitioning stock to fodder beet over 14- 21 days) and dose with Ruminant to help boost rumen microbial growth and thereby allow the rumen microbial populations to adapt rapidly.

After animal health problems, antibiotic use and wormers Conditions like acidosis and grass staggers depress the stock’s appetite and production. High acid levels in the rumen, and the use of antibiotics and dewormers can also adversely affect the rumen microbial populations and therefore rumen fermentation. Follow your vet’s treatment plan for the health problem and dose with Ruminant to help restore rumen microbial populations and digestive efficiency.

Prior to transportation e.g. to sale yards, for export Transportation is extremely stressful for animals. Prior to transport, moderately restrict feed intake, feed hay or silage as the low water content will help reduce the liquid content of effluent, and supplement with magnesium (with vet’s advice). Dose with Ruminant prior to transport to reduce transport stress and help with feed change pre and post transport.

Pre or post cold or hot weather events When stock suffer from heat or cold stress more energy is partitioned towards maintaining body temperature and there is less energy for meat and wool production. Under heat stress the cattle’s rate of gut and rumen motility, appetite and feed intake is reduced. Ensure plenty of water and shade is available and dose with RuminantTM to improve digestive efficiency. Under cold stress stock increase dry matter intake and rumination. Provide sufficient feed and dose with Ruminant to help stimulate rumen function and digestive efficiency.
