Efficiency of application of synbiotic "Rumistart" for calfs

The purpose of the research was to determine efficiency of a synbiotic "Rumistart" for calves of the dairy period. The research was conducted under the production conditions by the JSC "Orlovskoye" on the breeding work of the Orel district, Orel region. To carry out the research, clinically healthy calves of the Holstein breed at the age of 1 month were selected by the principle of analogs of couples (on date of birth, body weight). The differences between groups of animals were the following: the control group received only the main diet, skilled groups received synbiotic "Rumistart" within 30 days together with the main diet: the 2nd group - in a dosage of 15 g per head a day, the 3rd group - 20 g per head a day, the 4th group - 25 g per head a day. As a result of the research it was established that application of "Rumistart" has a positive impact on the appetite of the calves during the post-dairy period and on indicators of growth and development of calves. During the experience the average live mass of calves of 1, 2 and 3 skilled groups surpassed control at 3.4%, 4.0% and 5.5% (P function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
