THE UTILISATION OF PROBIOTICS BIOPLUS; Saccharomyces Cerevisiae And Candida Utilis TO IMPROVE DAIRY CATTLE PRODUCTIVITY

Abstract

Lack of good quality feed during the year resulting in low milk production and
long calving interval in dairy cattle. Technology to improve the utilisation of low
quality feed by the animals is required. The technology should be cheap and easy to be adopted by the fanners. Probiotic Bioplus combined with Saccharomyces cerevisiae and Candidauutilis had been proven increased feed efficiency of low quality feed and high concentrate diet (> 50 % of total dry matter) then improve beef cattle’s productivity. Thus a study to improve dairy cattle productivity by using the combination of the three probiotics was undertaken. The study was conducted at dairy cattle farm in Jakarta Timur by using 30 dairy cattle in similar production status. They were divided into two groups of treatment, namely Control Group fed by basal diet consisted of field grass, concentrate and “tofu waste” and Treatment group fed basal diet plus the three probiotics. The measurements were undertaken on feed intake, milk production, milk fat content, feed conversion ratio and calving interval. The results showed that milk production was increased by 9 % from 8.5 L/day in Control Group to 9.3 L/day in Treatment group (P<0.05). Milk fat content increased from 4.02 % in Control group to 4.19 % in Treatment group (P>0.05). Feed conversion ratio reduced from 1.4 to 1.0 kg DM/L milk produced (P<0.05). Control group has longer calving interval (495 days) compared to 382 days in Treatment group (P<0.05). The conclusion of the study is that the introduction of the three probiotics to dairy cattle increased milk production, milk fat content, feed conversion ratio and reduced calving interval period.
