Abstract:
This study was conducted in order to investigate the effect of different levels of a type of mineral ‎biochar obtained from Kohbanan mine in Kerman on the performance, digestibility, blood ‎parameters and ruminal fermentation of suckling Holstein calves in an industrial cattle farm. For this ‎purpose, 35 Holstein calves with an average weight of 48.88 ± 4.87 were used in a completely ‎random design in five treatments and seven replications.The experimental rations include: 1) milk ‎and ‎starter feed (basal ration), 2) basal diet with 10 g of mineral biochar mixed in the starter feed, 3) ‎‎basal diet with 10 g of mineral biochar dissolved in milk, 4) basal diet with 20 g of ‎mineral biochar ‎mixed in the initial feed, 5) basal diet with 20 g of mineral biochar ‎dissolved in milk. Consumption ‎of 20 grams of biochar in the initial feed increased the daily weight and improved the average feed ‎conversion coefficient . The highest amount of blood glucose and albumin concentrations ‎was related to calves fed with 20 g of biochar in ‎the initial feed. Calves consuming 10 and ‎‎20 g of biochar in the starter feed had the ‎highest apparent digestibility of nutrients. ‎Calves fed with 20 g of biochar in the initial ‎feed had higher rumen pH than the other calves. Therefore, the addition of 20 g mineral biochar to the starter diet of Holstein calves is ‎recommended because of its positive effects on performance, digestibility blood parameters and ‎rumen fermentation.‎
