this experiment was carried out to investigate the effect of adaptation period to oak leave's tannin on rumen ph and ammonia, rumen microbial population, gas production and dry matter true digestibility (ivtdmd) in alamout goat’s rumen (with no previous history of oak leaf consumption) compared with markhoz goat (with previous history of oak leaf consumption). the goats were fed either oak...

Material and methods Seventy-two growing mink where allocated into six groups with 6 males and 6 females. The control group was fed a conventional diet (30% of metabolisable energy (ME) from protein) whereas the 5 remaining groups were fed a LP diet (20% of ME from protein) and supplemented with crystalline amino acids (0.8% alanine, 0.5% taurine, 0.5% arginine, 0.5% methionine) or 2.5% dextros...

to estimate the grazing capacity in each region it is necessary to determine animal requirement based on forage quality and animal unit weight of dominant sheep breed. in present study animal unit weight of farahani sheep breed was investigated. two herds were selected. thirty animals including 15 three and four years' old ewes, 5 nine months old lambs, 5 six months old lambs, 5 three and four ...

Food energy values used for nutrition labelling and other purposes are traditionally based on the metabolisable energy (ME) standard, which has recent support from. By reference to current practices and published data, the present review critically examines the ME standard and support for it. Theoretical and experimental evidence on the validity of ME and alternatives are considered. ME and alt...

Cattle fed grass silage diets have been reported to have high carcass fat:protein ratios. The effect of grass silage and dried grass diets, fed at different levels of intake to ensure a range of equivalent metabolisable energy intakes (MEI) from 1 .1 x metabolisable energy requirement for maintenance to ad libitum, on fat and protein metabolism in twenty-four Hereford x Friesian steers was inve...

The use of sensors for monitoring livestock has opened up new possibilities the management in extensive grazing systems. work presented this paper aimed to develop a model predicting metabolisable energy intake (MEI) sheep by using temperature, pitch angle, roll distance, speed, and time data obtained directly from wearable on sheep. A Deep Belief Network (DBN) algorithm was used predict MEI, w...
