this study was conducted to determine the nutritive value of fresh and ensiled whole and partly stoned olive cake (oc) with or without molasses i.e., 0 and 50 gkg-1 on fresh basis. dry matter (dm), organic matter (om), crude protein (cp), neutral detergent fiber (ndf), acid detergent fiber (adf), lignin (sa), ether extract (ee), water soluble carbohydrates (wsc), and total phenols (tph) of all ...

A study was conducted to evaluate the effects of chitosan on enteric methane (CH4) and total tract nutrient digestibility of beef heifers consuming either a high-concentrate (HC; 85% concentrate) or a low-concentrate (LC; 36% concentrate) diet. Heifers were provided their respective diets ad libitum along with one of three dietary inclusion rates of chitosan: 1) CTRL=0.0% of chitosan in the die...

The objective of this study was to evaluate the effects of replacing dry ground corn with crude glycerol on intake, apparent digestibility, performance, and carcass characteristics of finishing beef bulls. A completely randomized block design experiment with 25 d for adaptation and 100 d for data collection was conducted, in which 3,640 Nellore bulls (367 ± 36.8 kg; 18 ± 3 mo) were blocked by b...

metabolizable protein (mp) supply and amino acid balance were manipulated through selection of highly digestible rumen-undegradable protein (rup) sources. effects on production efficiency and n utilization of early post-partum dairy cows were determined. forty-two multiparous and 16 primiparous holstein cows were assigned to the diets in a randomized complete block design immediately after part...

The present study was conducted to evaluate the effects of using raw or microwave irradiated safflower seed on dry matter intake, milk production and composition, milk fatty acid profile, blood parameters, and nutrient apparent digestibility in early lactation cows. Nine multiparous Holstein cows at early lactation were randomly assigned to one of three treatments based on 3 × 3 balanced latin ...

This study evaluated the effects of gradual replacement barley with oats on enteric CH4 emissions, rumen fermentation, diet digestibility, milk production, and energy utilization in dairy cows fed a grass silage-based diet. Sixteen lactating Nordic Red received total mixed ration [58:42 forage:concentrate dry matter (DM) basis]. Grass silage (Phleum pratense) was sole forage canola meal (10% DM...

introduction this study was conducted to evaluate the effect of essential oils of oregano, sweet orange and cumin on chemical composition, parameters of gas production capacity, aerobic stability and degradability of dry matter corn silage carried. secondary metabolites such as essential oils have antimicrobial properties that by adjusting ruminal fermentation in ruminants to improve the use of...

A study was performed to: 1) compare total tract digestibility of nutrients for three annual summer forages: Mulato II (hybrid Brachiaria); “Tifleaf 3” Pearl Millet (Pennisetum glaucum); and “Hay Day” Sorghum sudan (Sorghum bicolor) and 2) determine the efficacy of two digestibility markers: titanium dioxide (TiO2) and chromic oxide (Cr2O3) used with a fecal sample collection protocol of either...
