Two experimental factors (dietary treatment with or without pelleted-concentrate supplement (PCS) and sex) were investigated in crossbreed post-weaning calves to monitor their effects on performance, hematological profile, and plasma mineral concentration. Twenty-four post-weaning calves were classified according to sexually (either male or female) and randomly distributed into two dietary trea...

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...

The concept of a 'good life' recognises the distinction that an animal's quality of life is beyond that of a 'life worth living', representing a standard of welfare substantially higher than the legal minimum (FAWC, 2009). We propose that the opportunities required for a 'good life' could be used to structure resource tiers that lead to positive welfare and are compatible with higher welfare fa...

Background & Aims: The prevalence, incidence, and complications of heart disease increase with age. Green tea is an antioxidant which can prevent cellular senescence and cardiovascular diseases. Telomerase enzyme decreases with aging. Acute exhaustive exercise results in disturbances in the oxidative system and production of active oxygen species in the heart tissue. Thus, the present study aim...

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...

background: exercise has positive and negative effects on immune system. herein, we would like to investigate the effects of incremental aerobic training and fish oil supplementation on the plasma levels of crp, cpk and il-17 in trained mice. one of the major roles of immune system is to produce soluble or cellular components that provide the immunity against inflammatory agent. the purpose of ...

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...

If household income is pooled and then allocated to maximize welfare then income under the control of mothers and fathers should have the same impact on demand. With survey data on family health and nutrition in Brazil, the equality of parental income effects is rejected. Unearned income in the hands of a mother has a bigger effect on her family's health than income under the control of a fathe...
