Effects of Synchronizing the Rate of Dietary Energy and Nitrogen Release on Ruminal Fermentation, Microbial Protein Synthesis, Blood Urea Nitrogen and Nutrient Digestibility in Beef Cattle
The results of this research indicate that synchronizing the rate of degradation of dietary energy and nitrogen release improves ruminal fermentation, microbial protein synthesis and feed utilization.
The effect of dietary coconut kernels, whole cottonseeds and sunflower seeds on the intake, digestibility and enteric methane emissions of Zebu beef cattle fed rice straw based diets
The two cattle breeds were not different in their dry matter intake per body weight (or metabolic body weight) and digestibility, but the corresponding values for the oil plant dietary treatments were less when corrected for drymatter intake, organic matter intake, metabolic size or gross energy intake.
In Sacco Degradation Characteristics of Protein Feed Sources in Brahman-Thai Native Crossbred Steers
The nutritive value of six protein feed sources were determined using the nylon bag technique in rumen fistulated Brahman-Thai native crossbred steers. The steers were fed 0.5% BW of concentrate and
Effects of feeding level on methane emissions and energy utilization of Brahman cattle in the tropics
It is found that increasing feeding level increased average daily gain of Brahman cattle and the observed increased energetic efficiency was attributed to reduced energy output in urine, methane and heat production.
In Vivo Nutritive Value of Pangola Grass (Digitaria eriantha) Hay by a Novel Indirect Calorimeter with a Ventilated Hood in Thailand
A new animal calorimeter using a ventilated hood was constructed in Thailand and the recovery rates of the head cage were 96.5%, 97.0%, 95.7%, and 101.8%, which are reliable compared with Japanese whole-body chambers.
Enteric Methane Emission, Energetic Efficiency and Energy Requirements for the Maintenance of Beef Cattle in the Tropics
This study was conducted to determine the energy balance of beef cattle by indirect animal calorimetry utilizing a ventilated head box respiration system. Fifteen native Thai bulls were randomly
Environmental impacts of extensive and intensive beef production systems in Thailand evaluated by life cycle assessment
Abstract Beef production is rapidly increasing and is accordingly becoming intensified in Southeast Asia, and the changes in beef production systems could contribute to large changes in the
Feed intake, digestibility and energy partitioning in beef cattle fed diets with cassava pulp instead of rice straw
It is demonstrated that increasing the proportion of cassava pulp up to 500 g/kg of dry matter as a base in a fermented total mixed ration is an effective strategy for improving productivity in zebu cattle.
