Article Synopsis
- * Three drying techniques (sun drying, oven drying, and freeze drying) were tested, showing that dried E. cottonii significantly decreased methane production while improving dry matter (DM) and organic matter (OM) degradability.
- * All three drying methods had similar effects on methane reduction, but freeze drying proved to be the most effective method without negatively affecting rumen bacterial activities or total volatile fatty acid (VFA) production.
Article Synopsis
- The study investigates the potential of using rice straw, along with protein extracted from leaves, as livestock feed to improve nutrition and digestibility.
- Distilled water was found to be more effective than chemical solvents like 0.1 N NaOH for extracting protein from leaves, yielding higher protein and amino acid content.
- Incorporating this distilled water-extracted protein into low-quality rice straw diets resulted in better fermentation and digestibility, suggesting a viable method to enhance livestock nutrition.
Objective: The aim of this study was to predict the body weight (BW) of a Belgian Blue X Friesian Holstein (BB X FH) crossbred in Indonesia based on morphometrics using random forest.
Materials And Methods: A total of 26 BB X FH crossbreds were observed for BW, chest weight (CW), body length (BL), hip height (HH), wither height (WH), and chest girth (CG) from 0, 30, 60, 90, 120, 150, 180, 210, 240, 270, and 300 days of age. Stepwise regression and random forest were performed using R 3.
Objective: Different sources and levels of starch in the total mixed ration might result in different rumen fermentation profiles, rumen microbial composition, and enteric methane production. The current study aimed to evaluate the effect of dietary starch intake on enteric methane production through a meta-analytical approach by integrating related published studies.
Materials And Methods: Papers that provided study results on enteric methane production from cattle fed different sources and levels of starch were selected.
