Nitrate can be a source of NPN for microbial growth at the same time that it reduces ruminal methane production. The objective of this study was to evaluate the effects of 2 encapsulated nitrate products used as urea replacers on blood and rumen constituents, methane emission, and growth performance of lambs. Eighteen Santa Inês male lambs (27 ± 4.9 kg)(More)
Brazilian red propolis was administered orally to Santa Inês ewes, and evaluation was made of general health and hematological, biochemical, and parasitic responses during and after flushing. Thirty mature, nonlactating, nonpregnant Santa Inês ewes (40 ± 2 kg and 2.5 years old) were grazing tropical pasture (Brachiaria decumbens and Pennisetum purpureum)(More)
Twenty Santa Inês ewes used to evaluate effects of oral administration of Brazilian red propolis extract on blood metabolites, milk production, and lamb performance were randomly grouped (n = 10 ewes/group) to control without propolis administration and propolis treated (3 g red propolis extract/ewe/day) 21 days before expected lambing date.
