Since 1990, the number of livestock in Mongolia has more than doubled. In large areas Mongolia, grassland degradation is now a problem national concern. A survey was done 10 herders two Soums (Altanbulag and Khashaat; heavily moderately degraded, respectively) to measure animals (sheep, goats, cattle horse numbers, sex weights) grasslands (species biomass) every 3 months from April 2017 Decembe...
Context An accession of the annual legume Trigonella balansae Boiss. & Reuter. has been selected for commercial release in Australia. Aims As part a duty-of-care assessment, we tested hypothesis that sheep grazing trigonella will have liveweight, condition scores and wool production similar to those two widely adopted legumes, subterranean clover (subclover, Trifolium subterraneum L. cv. Da...
The aim of this study was to establish relationships between chemical and physical parameters of wheat with performance and digestibilities of feed components in broiler chickens fed on wheat-based diets. Ninety-four wheat samples were selected for inclusion in four bird trials. Birds were housed in individual wire metabolism cages from 7 to 28 d and offered water and feed ad libitum. Dry matte...
Litter management is important when rearing meat chickens because litter conditions can affect production as well chicken health and wellbeing. An industry survey was conducted to gather information from Australian growers integrators about their practices, providing an opportunity share knowledge, experiences perceptions re-use turning. This essential for researchers investigating practices it...
An experiment investigated whether the inclusion of chicory (Cichorium intybus) in swards grazed by beef steers altered their performance, carcass characteristics or parasitism when compared to steers grazing perennial ryegrass (Lolium perenne). Triplicate 2-ha plots were established with a chicory/ryegrass mix or ryegrass control. Forty-eight Belgian Blue-cross steers were used in the first gr...
Four experimental diets were formulated to contain 700 g/kg cereal with decreasing levels of wheat:barley inclusion. Diet 1 contained 700 g/kg wheat, diet 2 contained 600 g/kg wheat and 100 g/kg barley, diet 3 contained 500 g/kg wheat and 200 g/kg barley and diet 4 contained 400 g/kg wheat and 300 g/kg barley. The diets were offered to pigs on three trials to investigate effects on the performa...
Reducing greenhouse gas emissions associated with ruminant livestock production is important for climate change mitigation. Regenerative Agriculture (RA) practices are increasingly promoted to improve forage and performance in temperate systems. These include i) rotational grazing (RG) of around multiple subunits pasture achieve ungrazed periods ‘rest’, ii) herbal leys (HL), where perennial for...
