The use of non-hormonal growth enhances with different nutritional levels for growing Friesian calves until slaughter
Abstract: Twenty-four growing Friesian calves of about 217.5 kg L.B.W. were divided equally into 6 experimental groups according to their live body weight, the experimental treatments were schemed as follows:
Treatment(1): 40% roughage: 60% concentrate (control)..
Treatment(2): 20% roughage: 80% concentrate (control).
Treatment(3): 40% roughage: 60% concentrate plus 10gm yeast/head/day.
Treatment(4): 20% roughage: 80% concentrate plus 10gm yeast/head/day.
Treatment(5): 40% roughage: 60% concentrate plus 10grn lactosacc/head/day.
Treatment(6): 20% roughage: 80% concentrate plus 10gm lactosacc/head/day.
Average daily gain, feed conversion, some rumen and blood parameters and economical efficiency for fattening trials were determined.
Results of using treatments revealed, no effects were detected of using yeast with the level of "10" gram/head/day.
But significant effects were detected of using lacto-sacc with the level of "10" gram/head/day.
Key Words: Yeast, Lacto-sacc, Growing and Friesian calves performances.
