This research was conducted to estimate the amount of microbial protein synthesis in Iranian buffaloes' rumen. Four male swamp buffaloes with average live body weight of 140±10 kg were used in this study. Four diets of 0 (control diet, 100% forage), 15, 30 and 45% concentrate in a 4 × 4 Latin Square were tested. The results indicated that by increasing the concentrate level in the diet of swamp...

The aim of this study was to use meta-analysis to identify the enteric methane (CH4) mitigation strategy that reduced CH4 emission without lowering production. To this end, a database initially developed was updated, compiling data from 61 publications (233 experiments) for various observations in dairy cattle on effects of hydrogen sink (H-sink), ionophore, lipid and conc...

Profitability of different grouping criteria was simulated in a dairy farm with 153 lactating cows that were divided into three groups of high (79), medium (40) and low (34) cows based on the milk records. Animals were reassigned to the new groups based on the following criteria using a decision support tool and the same three groups scenario: fat corrected milk 4%, days in milk (DIM), dairy me...

In this research work, the zinc extraction was investigated, using bioleaching process from a low grade zinc concentrate which was produced from the accumulated flotation tailings. Zinc content was initially upgraded to 11.97% by flotation process. Bioleaching experiments were designed and carried out by a mixed culture of Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans, Leptospir...

date syrup, date concentrate and date liquid sugar are among the products which are produced from low quality dates in date processing plants. the aim of this research was to investigate chemical characteristics and sensory properties of date syrup, date concentrate and date liquid sugar in comparison with sugar (sucrose) solutions and evaluate possible substitution of sucrose with these date b...

Recently, consumers have become more concerned with foods contain natural ingredients in terms of health and economic. Hence, in this study the effect of concentrate of smoked and sun dried raisin at 3 levels (1, 3 and 5%) as a natural humectant to improve the quality and shelf life of flat bread were investigated. Results showed that addition of smoked and sun dried raisin improved quality and...

Metals used in everyday life are produced from ores occurring in the Earth’s crust. Geological processes are known to concentrate minerals to form ores of economic value. Mineral processing engineers concentrate these ores by mechanical and physico-chemical methods while the extractive metallurgist extracts the metals by chemical means.
