The ileal digestibility of amino acids and fatty acids in young chickens fed control diet or experimental diets supplemented with freeze-dried pasture herbage at 20 or 40 g/kg was studied. Control die...
The rodent disaster is one of the main biological disasters in grassland in northern Xinjiang. The eating and digging behaviors will cause the destruction of ground vegetation, which seriously affecte...
The effect of grazing on the productive performance and meat quality was evaluated for chickens (Ross 308, n = 192). Chickens were kept in two pens on wooden shavings (2 × 96) from one day of age. O...
Economical and ecological issues as well as consumer demand for sustainably produced agricultural food rise the trends to fatten beef cattle on pasture during the grazing season. However, particularly...
The aim of this modelling study was to investigate the effect of large herd size (and land areas) on walking distances and milking interval (MI), and their impact on milk yield and economic penalties ...
To maintain a predominantly pasture-based system, the large herd milked by automatic milking rotary would be required to walk significant distances. Walking distances of greater than 1-km are associat...
One of the challenges to increase milk production in a large pasture-based herd with an automatic milking system (AMS) is to grow forages within a 1-km radius, as increases in walking distance increas...
The present study evaluated the effect of controlled ryegrass-white clover herbage availability from day 128 until day 142 of pregnancy in comparison to unrestricted availability, on the performance o...
Studies of the migratory dynamics of cyathostomin infective larvae (L3) in different seasons and with two types of irrigation were carried out over 12 months (September 2006 to September 2007) in the ...
This study shows a application of remote sensing techniques for the evaluation of conversion from forest to pasture in the State of Rondonia, Brazil. The main objective of this study was to establish...
The objective was to evaluate the ingestive behavior of crossbred heifers finished on a Brachiaria brizantha cv. Marandu pasture receiving four levels of glycerin in their supplementation. Thirty-six ...
The objective of this work was to evaluate the nutritional parameters of young bulls supplemented with different ratios of protein: carbohydrate on tropical pastures from 4 until 18 months old. Fifty-...
The nutrient composition of pasture, voluntary intake and digestibility of diet ingested by goats grazing on an introduced Leymus chinensis pasture were measured across spring (May), summer (July), au...
Automatic milking systems (AMS) rely upon voluntary cow traffic (the voluntary movement of cattle around a farm) for milk harvesting and feed consumption. Previous research on conventional milking sys...
Pasture-based automatic milking systems (AMS) require cow traffic to enable cows to be milked. The interval between milkings can be manipulated by strategically allocating pasture. The current experim...
