PELLEGRIN, Ana Carolina Ribeiro Sanquetta de et al. Crude glycerin in supplement to suckling lambs on ryegrass pasture. Cienc. Rural [online]. 2012, vol.42, n.8, pp.1477-1482.  Epub July 10, 2012. ISSN 0103-8478.

The aim of this study was to evaluate the effect of levels of crude glycerin in the supplement intake and performance of suckling lambs on ryegrass pasture, beyond the qualitative and quantitative characteristics of ryegrass pastures. It was used 32 suckling lambs distributed between the treatments: 0, 10, 20 and 30% of crude glycerin, replacing corn, in the isoproteic supplement (18% CP) offered daily in an amount equivalent to 2% of body weight. There was no effect (P>0.05) of the levels of crude glycerin on the qualitative and quantitative characteristics of pastures, composition of crude protein and neutral detergent fiber, stocking rate supported by ryegrass pasture, neither on supplement intake, average weight gain and number of days to slaughter the lambs. Levels up to 30% of crude glycerin, replacing corn, provided in the supplement to suckling lambs grazing ryegrass didn't compromise the supplement intake, performance and termination period of the animals.
