Effect of live-weight and live-weight change on the lambing performance of ewes
The Journal of Agricultural Science, 1962A flock of 320 Border-Leicester × Merino ewes was used to study the effects of pre-flushing and flushing treatments on subsequent lambing performances during the years 1958, 1959 and 1960. The flock was kept on non-irrigated perennial pastures in southern Victoria.In 1958 groups of ewes that lost a mean of 17, 5 and 0 lb. during the 4 weeks immediately

Weight maintenance and healthy living
1986The change to the maintenance programme should not be a sudden process, but should be gradually introduced as the target weight is reached. Unless this stage is successfully accomplished then the dieting process will have been a waste of time and the typical ‘yo-yo weight syndrome’ will occur. The important consideration is to establish not only a more

Prediction of carcass weight from live weight in beef animals
Proceedings of the British Society of Animal Science, 2005Beef production is the most important farm enterprise on Northern Ireland farms, accounting for 32.5% of Gross Agricultural Output. In beef production the end saleable product is carcass rather than live weight. When undertaking nutrition studies with beef cattle, it is essential to evaluate effects on carcass characteristics, as improvement in live ...

Live weight accounting for beef cow management
Livestock Science, 2022Calculation and use of annual live weight production of a group of beef cattle, ie, net harvest of live weight from their grazing area over a year, which is a primary beef cattle business measure directly indicating income, is limited in practice because it is not well understood and there is generally insufficient record keeping to achieve it.

Journal of Animal Science, 1993
The weight of the noncarcass external tissues, thoracic organs, and visceral organs was measured during live weight gain (LWG) and live weight loss (LWL) to evaluate the effect of different periods of normal and retarded growth on noncarcass organs. Thirty-five Merino wethers were allowed ad libitum access to an experimental diet of 80% alfalfa chaff ...

Inheritance of adult velvet antler weights and live weights in farmed red deer
Livestock Production Science, 1997Abstract Deer farmers maintaining stag herds for velvet antler production are interested in: selection of stags for superior lifetime performance; selection of sires and dams to produce improved sons; and management of the stag herd to increase returns from velvet antler.

Molecular weight distribution in living polymerization
Progress in Organic Coatings, 2006An easily obtained parameter for characterizing polymers is the molecular weight distribution (MWD). Polymers with different MWD have different properties. The MWD can be easily influenced with controlled polymerization technologies. Examples of how these methods influence the properties of block and gradient copolymers in wetting and dispersing ...

Live weight and future performance of pullets
Животноводство России, 2023Установлено, что при низкой живой массе в 18 недель куры достигают половой зрелости (50%-й интенсивности яйценоскости) позже, чем несушки с повышенной и оптимальной живой массой. При этом уменьшается яйценоскость и сохранность птицы, возрастают затраты корма на десять яиц.

Molecular Weight Distribution of Living Radical Polymers
Macromolecular Theory and Simulations, 2005AbstractSummary: A new Monte Carlo simulation method is proposed for the living radical polymerization on the basis of the random sampling technique. The stable free‐radical polymerization is used as a specific reaction mechanism. The illustrative calculations are conducted to investigate the effects of simultaneous use of two different types of ...
