Background: The rainbow trout fish is susceptible to spoilage due to its high content of unsaturated fatty acids. It should be kept at low temperature to reduce microbial, enzymatic, and oxidation reactions. The purpose of this study was to design a packaging that contains a pH indicator for monitoring freshness of the rainbow trout fish during storage at refrigerator. Methods: The indicator co...

Early warning indicators for process failures were investigated to develop a reliable method to increase the production efficiency of biogas plants. Organic overloads by the excessive addition of rapeseed oil were used to provoke the decrease in the gas production rate. Besides typical monitoring parameters, as pH, methane and hydrogen contents, biogas production rate and concentrations of fatt...

Objectives: The objective of this research was to investigate the chemical composition and antibacterial activities of the fatty acids and essential oil from various parts of Ligularia persica Boiss (L. persica) growing wild in north of Iran. Materials and Methods: Essential oils were extracted by using Clevenger-type apparatus. Antibacterial activity was tested on two Gram-positive and two Gra...

the aim of the current study was the screening the activity of 23 medicinal plants for decreasing the in vitro ruminal methane production, as well to and assess sheep ruminal in vitro fermentation parameters. 57.3 mg of each medicinal plants along with 142.7 mg control diet were weighted in 120 ml wheatons in 4 replicates. the samples were incubated using ruminal fluid obtained from 3 castrated...

The transition from normal forage to a highly fermentable diet to achieve rapid weight gain in the cattle industry can induce ruminal acidosis. The molecular host mechanisms that occur in acidosis are largely unknown. Therefore, the histology and transcriptome profiling of rumen epithelium was investigated in normal and acidosis animals to understand the molecular mechanisms involved in the dis...

The objective of this study was to investigate the effects of increasing maturity of whole-plant corn at harvest on CH4 emissions by dairy cows consuming corn silage (CS) based diets. Whole-plant corn was harvested at a very early [25% dry matter (DM); CS25], early (28% DM; CS28), medium (32% DM; CS32), and late (40% DM; CS40) stage of maturity. In a randomized block design, 28 lactating Holste...

The present study identified volatile flavor components of Hanwoo longissimus muscle and other Korean foods (Doenjang, Chungukjang, sesame oil) and their traits were compared in relation with flavor precursors that include fatty acids and protein degradation products. Hanwoo longissimus muscle was purchased from a commercial abattoir while the other foods were sampled from three separate househ...

The aim of this study was to determine the most optimal heating time in protection of protein rich feedstuff on digestibility and in vitro ruminal fermentation profile. Proteinous feedstuffs used in this study is soybean meal (Glycine max). This study is designed using one way ANOVA, with five treatments of heating time (T0 (control)= unheated, T1= 10 min, T2= 20 min, T3= 30 m...
