      abstract = {The breeding of replacements is fundamental in any  production system, since the heifers are the one that will  replace in a certain time the cows that gradually leave the  exploitation. Probiotics can form part of the composition  of different types of products, including foods (functional  foods), medicines and dietary supplements. The objective of  this study was to evaluate the feeding cost of Holstein  heifers fed with whole milk added with Bacillus subtilis  PB6. 60 new-born animals were used, randomly included in 1  of 3 treatments. The treatments were as follows: T1 =  control, T2 = 10 g heifer day. The First Take within 20 min  after birth, T3 = 10 g heifer day. The first takes between  12 and 24 h after birth. In All treatments 432 L of  pasteurized whole milk was supplied divided into two  outlets day 07:00 and 15:00 respectively, for 60 days, the  addition of Bacillus subtilis PB6 was carried out in the  milk tub at the time of feeding them. The first intake of  colostrum (2 L•intake) per animal, was supplied within 2 h  after birth, then provided a second 6 h after the first.  The variables to evaluate the cost of feeding were  considered milk consumption and concentrate during the  first 60 days of life. It Was concluded that in the  evaluated variables no statistical difference was observed  P<0.05. In relation to the cost of feeding and the cost  integrated by kilograms, it is observed lower cost for the  T2, corresponding to the heading of the feeding of heifers  with whole milk added with Bacillus subtilis PB6, improved  the relation benefit-cost.},
