Three series of trials were conducted to evaluate the effect of monensin on the growth performance of cattle. Twenty-four trials were conducted to evaluate the addition of monensin at 200 mg/d to limited quantities of supplemental concentrate for growing cattle grazing pastures. The pastures ranged from dormant end-of-the-season grasses and crop residues to lush green pastures, and were located...

Management strategies to reduce heat stress are needed, especially when there is no or little shade in pasture-based dairy systems. We investigated management practices used load summer: milking later it cooler, feeding later, and only the morning. Fifteen groups (n = 4 pregnant Friesian-cross cows/group) were managed on pasture milked at 0700 h followed by a new allocation including silage one...

this study develops a long run optimal pattern for nomadic ranchers of fars province under climate uncertainty by simulating dynamic process of livestock and forage productivity as well as employing dynamic stochastic programming. results indicate that the nomadic representatives do not perform, optimally. despite their attachments to livestock as an asset, and their life dependency on livestoc...

Ergot alkaloids have been associated with endophyte-infected grasses (e.g., the Epichloë, Bacon et al., 1977 and Balansia, Porter et al., 1979 spp.) with examples including tall fescue and fescue toxico-sis in the United States (Yates et al., 1985) as...

Twenty-four yearling male local Washera lambs with an average initial body weight of 18.14 ± 1.07 kg were used to assess the nutritional value of Millettia ferruginea. Experimental animals were grouped into six blocks of four animals, and each animal was randomly assigned to one of the four dietary treatment feeds. The treatments used were; Sole natural pasture grass hay (T1), and 150, 300, 450...
