With the milk to feed ratio at 2.36 in February, 2008, dairy managers must carefully reviewing feed inputs relative to milk yield. A milk to feed ratio under 3 is a signal to reduce feed inputs. Feed efficiency (also referred to as milk performance efficiency and dairy efficiency) can be defined as pounds of 3.5%FCM (fat corrected milk) produced per pound of dry matter (DM) consumed. Monitoring...

Many Trichoderma species are able to produce 6-pentyl-α-pyrone (6-PP), a lactone with coconut-like aroma. In the present work, several culture parameters were studied to enhance the production of 6-PP by Trichoderma harzianum 4040 in solid-state fermentation. Green coir powder added to a nutrient solution was used as support material for fermentation. A Plackett-Burman screening technique was a...

This paper addresses whether the ecosystem service of animal production from grasslands depends upon plant functional identity, plant functional diversity or if the resilience of production is a function of this diversity. Using the results of nine grazing experiments the paper shows that productivity is highly dependent on one leaf trait, leaf dry matter content, as well as rainfall. Animal (s...

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...

Introduction The production of ethanol from corn grain has become an effective strategy to produce high quality and clean liquid transportation fuels. In fact, the growth of the U.S ethanol industry has provided an economic stimulus for U.S.-based agriculture. The feed industry plays an integral role in the ethanol production industry. For example, the primary product of the dry milling product...

sphere represents less change in CO2 concentrations at the RuBisCO binding sites for C4, resulting in a smaller Atmospheric CO2 and temperature may significantly modify plant response for the C4 compared with the C3 plant. High production. Grasslands occupy in excess of 25% of the Earth’s land area, but grassland species have received limited attention from retemperature also generally increase...

the percentage of fat in liver wet and dry matter, liver moist and dry matter and their relationship were investigated based on species, sex and age of 384 slaughtered animals including 114 cows, 100 buffaloes, 147 sheep and 23 goats from 2008 to 2010 in urmia, iran. mean percentage of fat in liver wet and dry matter, and liver dry matter in cows were 3.6%, 1.1%, 29.7%, buffaloes were 5.3%, 1.5...

To investigate a model to simulate wheat dry matter accumulation, three wheat cultivars with different tillering abilities were grown at three densities each in a field experiment. Five simulation models with high correlation coefficients for relative dry matter accumulation were established by the method of normalized. Among these models, the Richards equation was the best in fitting and forec...
