Thirty two multiparous Holstein cows were used in a randomized block design to investigate the effects of feeding diets included two different source of nonfiber carbohydrate during the transition period on dry matter intake (DMI), lactational performance, blood metabolites and parturitional characteristics. Cows received total mixed rations containing either macaroni wastes(MW) or steam-flaked...

Behavioral, physiological, and blood biochemistry of Friesian Holstein dairy cattle at different altitudes in West Java, Indonesia. Biodiversitas 23: 533-539. For cows, the study physiological aspects those related to it is very important based on altitude. The data this are main considerations determine ability ho...

In a previous study from 2014 it was found that US Holstein cows that gave birth to heifer calves produced more milk than cows having bull calves. We wanted to assess whether this is also true for Danish cattle. Data from 578 Danish Holstein herds were analysed with a mixed effect model and contrary to the findings in the US, we found that cows produced higher volumes of milk if they had a bull...

The association between blood calcium levels and electrocardiographic variables was compared in 137 normal parturient and 36 peripartum recumbent Holstein cows to determine whether hypocalcemia in peripartum dairy cows can be rapidly diagnosed using electrocardiograph. Inverse of STc (ST peak interval/SS interval(0.5)) and blood ionized calcium or serum calcium concentrations were strongly corr...

OBJECTIVE This trial was performed to examine the effects of ruminally degradable starch (RDS) levels in total mixed ration (TMR) with low corn-based starch on the milk production, whole-tract nutrient digestibility and nitrogen balance in dairy cows. METHODS Eight multiparous Holstein cows (body weight [BW]: 717±63 kg; days in milk [DIM]: 169±29) were assigned to a crossover design with two ...

the study was conducted to know the effect of flushed feeding on estrus synchronization and conception rate of holstein ílocal crossbred cow’s after using the gnrh (fertagyl) and pgf2α hormone. as a representative sample 20 holstein ílocal crossbred cows were chosen from chittagong cantonment military dairy farm in bangladesh and the experimental work was carried out for 60 days. ten cows were ...

Gender of the calf whose birth initiates lactation could influence whole lactation milk yield of the dam due to hormonal influences on mammary gland development, or through calf gender effects on gestation length. Fetal gender could influence late lactation yields because cows become pregnant at peak lactation. The effects of calf gender sequences in parities 1-3 were assessed by separately fit...

Introduction Investigating and comparing the two systems Comparing some technical efficiency ratios and profit Points to note about the comparison Conclusions References Abstract. In this study, budgets of herd dynamics, feed and energy supply, production and profit of alternative dairy farm systems were used to examine the effects of changing a 230 cow Holstein-Friesian (HF) dairy system to a ...
