Resting time is inversely correlated with milk production and directly correlated with gestation length. Based on readings of thousands of cows fitted with pedometers in multiple farms, Afimilk has measured 500 to 700 minutes per day as the normal resting time for lactating dairy cows.
Under prevailing practices milk delivered to dairy plants is graded upon reception, according to acceptable standards of hygienic quality. In most countries, these standards include upper limits on transportation temperature, bacterial counts, antibiotic residues, and SCC (McLaughlin, 2006; USFDA, 2007).
Intramammary infection (IMI), comprises a group of costly diseases affecting dairy animals worldwide. Many dairy parlours are equipped with on-line computerised data acquisition systems designed to detect IMI. However, the data collected is related to the cow level, therefore the contribution of infected glands to the recorded parameters may be over estimated
Feeding for efficient milk production leads in modern dairy practice. Efforts to maintain production and fertility at optimal levels under given market, husbandry and feeding conditions, often fail. Yet, financial
losses for an “open day” are estimated in various studies to be 2.5 to 5.0 US$.
Control of production Diseases often involves various disciplines and therefore calls for a “multivariate approach”. Such an approach, centered on the herb, had led to the adaptation of integrated programs of the herd health,
Disease in fresh cows is probably the factor with the most devastating effects on milk production and reproductive performance. The objective of this study was to evaluate parameters that can be easily measured on a farm to determine their ability to detect subclinical disease in fresh cows
Early detection and intervention are obviously critical for preventing major losses, but the vast majority of ketosis cases are subclinical, meaning there are no overt signs of disease.
Cows with concentration of ketones in blood ≥1.2 mmol/L in early lactation had a higher risk of PVD and lower 6-week PR. Cow and herd-level prevalence of SCK varied widely in early lactation.
Mastitis is the most costly disease affecting daily cattle. Losses occur from decreased milk production, treatment and labor costs, non deliverable milk, veterinary fees, reduced milk quality, reduced milk price, increased risk of subsequent mastitis, culling and death of the cow.
The amount of swelling, severity of pain and the overall appearance of the cow will indicate the severity of infection and serve as a guide for the course of treatment
