During the past few winters several nomadic areas in the Tibet Autonomous Region (TAR) of the People's Republic of China have been greatly affected by unusually heavy snowfall. Losses in Nacqu Prefecture alone were estimated ar 1.03 million animals or about 15 % of the Prefecture's totallivestock population (MILLER, 1998). Thus far there have only been theories about the true causes of these ca...

The suggestion that modern pasture cultivars persist less well than their predecessors is not supported by facts. However in some regions there is a crisis in farmer experience of persistence of ryegrass pastures, and ryegrass breeding can contribute to a resolution. This paper considers the turnover of tillers in a pasture, the population structure of a grass sward and the involvement of endop...

The daily BW gain of stocker steers grazing tall fescue [Lolium arundinaceum (Schreb.) S.J. Darbysh. = Schedonorus arundinaceus (Schreb.) Dumort.]-based pastures typically declines during summer. To avoid these declines, in part to mitigate the effects of tall fescue toxicosis, it is commonly advised to move cattle to warm-season forage during this period. A 3-yr (2006, 2007, and 2008) grazing ...

Introduction Biologists lack a great deal of information about wildlife in the Nebraska Sandhills, especially on private rangelands. For example, there is little knowledge about the small mammals of the area and their role in the ecosystem in which they live. Because only three percent of Nebraska is public land (Schneider et. al 2005), private land management is, by default, critical to the bi...

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...

the copper level in the serum of 1280 and liver of 200 goats raised in the mountain areas of khuzestanprovince, iran were determined. copper, molybdenum and iron content of soil and pastures as well as sulfurcontent of the pastures were seasonally estimated. mean serum copper levels of goats in behbahan,ramhormoz, eizeh and masjed-soleyman districts were 8.14 ± 0.21, 1.98 ± 0.12, 7.74 ± 0.11 an...

We evaluated short- (among months within-years) and long-term (between 1999-2000 2016-2017) temporal patterns of taxonomic functional β- diversity (and its components substitution gain/loss) dung beetle assemblages in forest fragments pastures the Los Tuxtlas Biosphere Reserve (LTBR). Habitat type affected dissimilarity richness difference component, with average values being respectively 1.42 ...
