Influence of Dietary Energy and Protein Intake on Yield and Composition of Milk in Crossbred Dairy Cows
The study was carried out on 120 crossbred Holstein × Shahiwal dairy cows for a period of 150 days to quantify the influence of dietary energy and protein intake on yield and composition of milk. Total 12 dairy farms having similar housing systems and holding at least 20 dairy cows in between mid to late lactation were selected for study purposes. The farms were located in the peri-urban and ur...
متن کاملThe Effect of Different Levels of Sesame Wastes on Performance, Milk Composition and Blood Metabolites in Holstein Lactating Dairy Cows
The objective of this study was to determine the effect of different levels of sesame wastes (SW) on performance, milk composition and blood metabolites in lactating dairy cows. In this order, eight multiparous Holstein dairy cows were used in a replicated 4×4 Latin square design in four periods of 21 days. Treatments were control (no Sesame meal supplementat...

متن کاملReproductive Challenges of High Producing Dairy Cows
Within a dairy herd, total milk production is determined by the proportion of cows producing milk at any given time and the level of milk production of the individual cows within the herd. Improving reproductive efficiency helps to maintain the maximal number of cows producing milk at optimal levels. Reproductive efficiency in dairy cattle currently is suboptimal primarily due to four factors: ...
متن کاملFurosemide Induced Electrocardiographic Alterations in High Producing Holstein Dairy Cows
Diuretics have several therapeutic advantages in dairy cows but there are different side effects such as acid-base and electrolyte imbalances which may affect the electrocardiographic parameters. Fifteen multiparous, clinically healthy, non-pregnant and high producing 4-year-old Holstein dairy cows at their early lactation period were randomly divided into 3 equal experimental groups. Furosemid...
