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.
