%Moisture & %Dry Matter Labs determine the %moisture content of submitted samples by drying the sample, and calculate the %dry matter; (DM% = 100 %moisture). Most lab analysis reports list test values on both the basis of %Dry Matter, and “As Fed”, “As Is” or “As Received.” Forage nutritive values should be evaluated, and rations balanced on a dry matter basis. Once the forage needs have been d...

In the dynamic modeling of dairy cow performance over a full lactation, the difference between net energy intake and net energy used for maintenance, growth, and output in milk accumulates in body reserves. A simple dynamic model of net energy balance was constructed to select, out of some common dry matter intake (DMI) prediction equations, the one that resulted in a minimum cumulative bias in...

Biochar amendments to soil have potential as a climate change mitigation strategy. However, their effect on carbon exchange in different ecosystems has not been well evaluated. Understanding how biochar affects carbon exchange from agricultural soil is essential for clarifying the contribution of biochar management to the carbon budget. We performed a laboratory and a two-year field experiment ...

concentration of co2 in the atmosphere is likely to increase up to 550 µmol mol-1 by the middle of 21st century. such an increase in the atmospheric co2 would affect plant growth, and as well the productivity of crop plants. a field experiment was conducted with two potato cultivars namely kufri surya and kufri chipsona-3 grown inside open top chambers (otcs) at ambient (385±30 µmol mol-1) vs. ...

Aims: To evaluate the effect of aflatoxin B1 (AFB1) on in vitro dry matter disappearance (IVDMD), gas production and ammonia-N formation of an alfalfa hay based diet using batch culture system. Place and Duration of Study: Department of Animal Science, between July 2011 and August 2012. Methodology: In an anaerobic batch culture system, 50 ml of buffered rumen fluid was dispensed into a 125-ml ...

the aim of the experiment was to determine the effect of different dry matter content and addition of silage inoculant on the ruminal protein degradability. alfalfa herbage was collected from two cuts and the fresh matter was sampled two times during each cut (with different dry matter content). during the preparation of experimental micro-silages, the chopped forage was treated with a microbia...

Sixteen steers (650 Ib) were used to determine the effects of corn moisture, protein concentration and monensin (Rumensin) on ration digestibility and nitrogen retention. The steers were placed in metabolism stalls and fed rations of high moisture corn (HMC) or dry rolled corn at two protein levels (9.3 and 12.3 percent) with two monensin levels (0 and 30 g per ton of feed). Monensin addition d...

breeding based on selection indices is an effective method for improving complex traits such as yield. to assess the efficiency of different selection methods, 50 genotypes of tall fescue (festuca arundinace) were evaluated under two moisture conditions including full irrigation (normal environment) and deficit irrigation (stress environment). the experiment was conducted according to a randomi...

thirty multiparous holstein dairy cows with average body weights of 687±15 kg and body condition scores of 3.25±0.15 were allocated to 1 out of each 3 groups, immediately after parturition (dim=11) and in a completely randomized design. the first group was fed diet low in rumen undegradable protein (rup; 5.1% of dry matter), the second group fed with medium rup (7.2% of dry matter) while the th...
