Resumen

High yielder cows optimal feeding is always a major question in farm management. We attempted to find the optimal yield- and weight group in a Holstein_Freisian herd. Handled more than 2000 milk record samples and concluded that the optimal body weight is about 600-650 kg. Also step up from medium yielder to high yielder is more cost efficient than pushing the milk production over 30 kg milk daily. Our results show that fitness traits and body scores are major factors and every 50 kg of extra weight rises the forage cost in average of 0,11 €cents. The mid-weight cows produce 25 kg of milk dail

Resumen

AbstractA relatively large part of the Slovak territory consists of the “marginal regions”, which in terms of the economy of ruminants keeping can efficiently produce animal commodities only occasionally. The geographic, social and economic stability of these regions is strongly influenced by the rearing of ruminants and the associated market milk production. The aim of this study was to evaluate the prevalence and aetiological agents of mastitis in two herds of dairy cows situated in the marginal parts of Slovakia. In total, 530 of the Slovak spotted breed and Holstein cows were involved in t

Resumen

Abstract In rodents and primates, insulin resistance develops during pregnancy and fades after parturition. In contrast, dairy cows and other ruminants maintain insulin resistance in early lactation (EL). This adaptation favors mammary glucose uptake, an insulin-independent process, at a time when the glucose supply is scarce. Reduction in circulating levels of the insulin-sensitizing hormone adiponectin promotes insulin resistance in other species, but whether it contributes to insulin resistance in EL dairy cows is unknown. To address this question, plasma adiponectin was measured in high-yi

Abstract In dairy production, mastitis is a major problem affecting animal welfare, productivity, and economy. Hospital pens are typically not used for cows with mastitis, except for severe cases involving recumbency. This field trial included 47 cows from three Danish herds followed for 8 d, of which days 1–5 involved the experimental housing. After day 5, all cows were kept with the lactating group. We examined lying behavior in dairy cows with naturally occurring, mild-moderate mastitis in hospital pens [single or group (depending on conditions on the farm), all with deep straw bedding] vs.

Resumen

Multiple ovulations and so multiple pregnancies have increased recently in dairy cattle. The incidence of the double ovulation impact in high producers at insemination may be over 20%. Twin pregnancies are undesirable as they seriously compromise the welfare and productive lifespan of the cow and herd economy. Clinical problems extend from the time of pregnancy diagnosis to pregnancy loss, abortion or parturition. Early pregnancy loss or abortion of multiple pregnancies lead in most cases to culling. In cows reaching their term, mean productive lifespan is up to about 300 days shorter for cows

Resumen

In order to achieve good reproduction and production results in herds of dairy cows, apart from basic conditions concerning housing, care and nutrition, it is necessary to carry out regular clinical examinations of genital organs. Such examinations are not carried out regularly in practice therefore often many reproduction disorders are not diagnosed timely. As consequence we have bad fertility results, considerably lower milk production and high level of culled females from the herd.

While cows are predominantly monovular, over the past 30 years the incidence of multiple ovulations and thus twinning has increased considerably alongside milk production. Multiple pregnancies are not desirable as they negatively affect the health of cows and the herd economy. Although causal mechanisms associated with multiple ovulations have been extensively revised, the process of multiple ovulations is not well understood. Recent studies on the thermal biology of the reproductive system have shown how thermal mechanisms may prevent or favor multiple ovulations. This review focuses on this

Resumen

Background and Aim: Milk production is one of the main props for the national economy. One of the crucial problems in this industry is subclinical mastitis, which harms this industry that considered the backbone of the economy. It is an infectious and zoonotic disease; the infection can spread between dairy animals through milkers' hands, and milking machines, while the human infection occurs due to the consumption of apparently hygienic milk. Staphylococcus aureus is one of the main causative agents of clinical and subclinical mastitis. It is also considered one of the bacteria incriminated i

Resumen

Costs are an important economic category that have a decisive influence on the definition of pricing policies and the formation of financial performance of the enterprise, characterizing the level of organization of production and application of technologies. According to expediency of their spending, costs are divided into productive and unproductive. Unproductive costs arise in the event of a violation of technology, deficiencies in the organization of production, etc. Therefore, it is necessary to ensure that the economic evaluation of unproductive costs in breeding dairy cattle is carried

Resumen

With the rise of factory farming, milk is now almost an unnatural operation. The modern dairy farm can have hundreds, even thousands of cows. Today’s average dairy cow produces six to seven times as much milk as she did a century ago. Currently, the United States is the largest producer of milk in the world, followed by India and China. India being one of the largest milk producer around the world, has to import a part of Milk products and its exports are negligible in the World Export Share. This paper tries to examine the issues regarding ‘Export Performance of Dairy Industry of India’

Resumen

Sharemilking is an entry point for new dairy producers in the New Zealand industry, and, traditionally, most sharemilking arrangements have been a 50:50 arrangement. These structures are rigid in the share of milk income and apportionment of operating costs between the land owner and sharemilker. With milk-price volatility rising, these types of arrangements increase the financial and business risks, particularly for sharemilkers. These risks are further compounded because the value of the primary asset owned by sharemilkers, i.e. cows, declines to a much greater extent than does the value of
