ISSUE FOCUS FEED & ADDITIVE MAGAZINE March 2022 25 phase have their own needs and challenges (Table 1). Phileo has developed a total nutritional program based on probiotics and postbiotics that looks at feed efficiency, rumen health, milk production, health and fertility. All with one goal: reaching the full genetic potential of the dairy herd and increasing the bottom line for dairy farmers. Phileo has therefore developed the Program Milk profit, which is built upon the proven benefits of 3 solutions: Actisaf® Sc47 yeast probiotic, Safmannan® yeast postbiotic, and the selenium enriched yeast Selsaf®, hereafter called the ‘yeast probotic’, ‘yeast postbiotic’ and ‘selenium enriched yeast’. Numerous trials have shown the benefits of supplementing dairy cows with these yeast solutions throughout the whole production period. TAKING CARE OF EACH LACTATION PHASE In the transition period, the Program Milk profit aims to improve energy balance and reduce the risks of subclinical ketosis to achieve better performance throughout lactation. Subclinical ketosis is responsible for a 20% reduction in dry matter intake (DMI), as well as a decline of 2kg of milk per day. Studies in which transition cows were supplemented with yeast probiotic showed an average increase of 2kg milk per cow per day in the first three months in lactation (Figure 1). With the current average milk price in Europe of 35.6 cents/kg and approximately 170 kg extra milk per cow in three months, this easily adds up to thousands of extra Euros for a mid size European farm. BETTER MILK AND IMPROVED PREGNANCY RATES At the peak and mid lactation period, the Program Milk profit prevents the risk of subclinical acidosis, boosting milk production, improving antioxidant status and milk quality. Supplementation with yeast probiotic and selenium enriched yeast from mid to late lactation helps limit progressive increase in SCC (Somatic Cell Count), generally observed in the weeks prior to drying off. Cows with low SCC in milk when drying off will be less prone to mastitis at the beginning of their next lactation. Animal health and feed efficiency is also key for reproductive function. No calf, no lactation. In a large-scale collaboration study between Phileo, and genetics company Gènes Diffusion, the yeast probiotic showed significant improvement. The supplemented cows had an overall AI success rate of 38% and Table 1 - Each lactation phase includes certain risks Lactation period Transition period (3 weeks prior calving - 3 weeks post calving) Peak and mid lactation (45 - 200 DIM) Mid to late lactation (200-305 DIM) Challenges - Reducing the negative energy balance (NEB) and the risk of ketosis - Keeping feed intake levels high - Ensuring optimal start of lactation - Prevention of subclinical acidosis - Optimising milk production levels and milk quality - Maintaining optimal FCR and body condition - Keeping Somatic Cell Count low - Ensuring optimal milk production and components - Improving FCR Figure 1 - Effect of yeast probiotic on milk production in the first 3 months of lactation.
