The objective of this study was to evaluate the nutritional and productive characteristics of primiparous lactating cows grazing on tropical pasture, using different levels of crude glycerin in the supplement. The experiment was conducted at Rancho Santana farm, located in Jequié city, Bahia, Brazil, in the period from December 21, 2010 to March 16, 2011. Ten ¾ Holstein × ¼ Dairy Gyr lactating primiparous cows, with 109±24 days of lactation and a mean age of 30±6 months and mean body […]

Two experiments were carried out to determine the nutritional value and to evaluate performance of piglets fed two types of crude glycerine (CG), which were made from vegetable oil (CGS) and a mix of animal fat + % soybean oil (CGA). In experiment I, a digestibility assay was conducted using 32 crossbred piglets (19.20±1.52 kg). The experimental unit consisted of one pig, with a total of four experimental units per diet. The glycerine levels used in the digestibility assay were […]
