At the Gaec du Coadic in Arzano (29), there has been a new ingredient in the cow’s ration since January 2022. Following a test proposed by Patrick Le Delliou (cattle nutrition technician), Jacques Valegant, breeder, adds Live Yeasts in his ration to produce the maximum amount of milk per place and improve his feed cost margin (MCA). He gained €0.7/DV/d of MCA with the use of Delta® Yeasts.
Personalized advice and follow-up
In this breeding at 35kg/cow, Patrick Le Delliou knows well that the objective of the breeding is to have a good regular production over the year while monitoring the margin on feed cost. He then advised the associates to give Delta® Yeasts a try. “I had noticed in specialized magazines that productive farms regularly contained them, so I agreed to try” explains Jacques Valegant, breeder. At the beginning of January 2022, before starting the distribution of Delta® Yeasts, Patrick Le Delliou accompanied by Nicolas Cherel, Phileo technician, recorded the data on rations, milk production and carried out adung sieving. After 6 weeks of use, these different data could be compared.
Tested and approved
The results were not long in coming, a milk gain was observed after 3 weeks of use. After 6 weeks, the data measured showed more than 2 kg of milk per cow, with an identical ration, while the stage of lactation had progressed by 19 days (from 164 to 183 days of lactation). The calculated feed efficiency was 1.66 kg of standard milk produced per kg of DM ingested. Patrick Le Delliou also noticed a 33% drop in residues in the dung sieves. During the distribution of the Delta® Yeasts, there was only 4% on the 5 mm grid and 13.5% on the 2 mm grid (optimum figures in terms of ration enhancement meaning good fiber digestibility).
With a few months of hindsight, Jacques underlines “there is better ingestion and regular milk production even during changes in ration or rises in temperature in the building”. Lactation persistence and primiparous starts are also better than in the past. The numbers from the trial showed an increased production of 3L for the top 50 LVs in the herd.
