an experiment was carried out to evaluate how interactions between forage to concentrate ratio and dietary crude protein level may alter nitrogen efficiency and ut-b expression in growing baluchi male lambs. four baluchi male lambs [30 ± 2 kg bw] were used in a 4 × 4 latin square design with 28-d periods and a 2 × 2 factorial arrangement of dietary treatments. the treatments fed forage: concent...

There is limited information regarding both nitrogen (N) and energy partitioning of dairy cows grazing well–managed tropical pastures. The objective this study was to investigate the N mid–lactation on rotationally grazed elephant grass using two pre–grazing targets: 95 % or maximum canopy light interception (LI95% LIMax) during regrowth. used 26 Holstein × Jersey arranged in a randomized compl...
