The objective of this study was to investigate relationships between animal personality (i.e., consistency in behavioral responses, also called temperament) and milk production in dairy cows. There has recently been a growing research interest in animal personality, which in production animals can have an important impact on welfare and production potential. Despite this, the relationship betwe...

Precision Dairy Farming is the use of technologies to measure physiological, behavioral, and production indicators on individual animals to improve management strategies and farm performance. Many Precision Dairy Farming technologies, including daily milk yield recording, milk component monitoring, pedometers, automatic temperature recording devices, milk conductivity indicators, automatic estr...

Dairy Farming is a class of agricultural, or more properly, an animal husbandry enterprise, raising female cattle, goats, or certain other lactating livestock for long term production of Milk, which may be either processed on site or transported to a dairy for processing and eventual retail sale. Most dairy farms sell the male calves borne by their cows/buffaloes usually for real production, ra...

hemorrhagic bowel syndrome is a highly fatal intestinal disease of adult dairy cattle with uncertain cause. in a dairy herd in khorasanrazavi province, northeast of iran, two cows showed depression, anorexia, decrease in milk production, ruminal hypomotility, bruxism and dehydration. at necropsy, massive hemorrhage and clot formation was observed within the jejunum and bacterial culture of the ...

the objective of this study was to evaluate the effect of different milking frequencies in the first 6 weeks of lactation on milk production and milk constituents, blood metabolic profiles and reproductive performance of fresh dairy cows. the milking frequencies imposed were three times daily milking for 42 days (3x), six times daily milking for the first 21 days of lactation and three times da...

Genetic improvement programs have done a great job selecting animals with superior genetics for milk production. Selection with emphasis on milk production is generally recognized as the single most important objective of breeding programs in dairy cattle worldwide. As a result of this improvement, the dairy cow has changed significantly over the past 7 decades with a remarkable increase in mil...

High yielding dairy cows are at an increased risk for many metabolic diseases, especially during early lactation when milk production increases, but with a lagging of feed intake. Namely, this combination leads to a negative energy balance (NEB). The animal attempts to supply the energy needs for milk production by increased lipolysis of adipose tissue. Nonesterifed fatty acids (NEFA) that are ...

An important branch of the modern global economy is food production. Our focus is milk production on dairy farms, the period in which cows produce milk (lactation) and the quantity of milk produced. Special attention will be given to the time-dependent function that describes the quantity of the milk produced over a lactation period. The respective graph is known as the lactation curve and is o...
