Abstract:

Staphylococcus sp. is a pathogenic bacteria that causes subclinical mastitis. These bacteria are divided into coagulase-negative Staphylococci (CoNS) and coagulase-positive Staphylococci (CoPS). CoNS bacteria are a group of normal flora on human and animal skin. However, several studies have proven that CoNS bacteria are the most commonly isolated microorganisms from the milk of dairy cows with subclinical mastitis. The ability to form biofilms is an important virulence factor for CoNS bacteria. Detection of biofilm formation was carried out on 54 samples of CoNS bacteria in the form of Stored

The milk samples to be used in this study were 32 with a ratio of 10 normal cow's milk samples as a control. The milk sample was examined using a lactoscan. The data obtained were analyzed using the Independent T-Test test. The results of the repeat breeding cow's milk samples for specific gravity, fat content, and Total Solids (TS) showed a s

Abstract:

We previously produced a cloned calf by nuclear transfer (NT) using cumulus cells removed from cumulus–oocyte complexes (COCs) after IVM. If both cumulus cells and oocytes are obtained identically and individually, and can be used simultaneously for NT, the production of cloned cows will be more expedient. And the cloned offspring produced from them will not exhibit the heteroplasmic mixed mtDNAs of donor cells and recipient oocytes. In this study, we examined the developmental potential of NT embryos using cumulus–oocyte complexes (COCs) collected from cows individually by ovum pickup (OPU).

Abstract:

AbstractIn a system in which cows are grouped and given differential access to feeding bins with different rations, and where these groups change over time, it is important to find out how a change in the ration (and hence feeding bin) affects the cow's feeding behaviour. Monitoring the locomotion of cows can be used to predict oestrus and improve health (lameness diagnosis), but activity monitors can also be used to estimate both activity and numbers of feeding visits by cows. Ice tag activity monitors were attached to the right hind legs of ten cows. Walking, standing, lying data and health

Abstract:

Performance characteristics of high genetic merit cows on different feeding systems are not only important to establish the biological and economic consequences of current genetic selection practices, but can be used also to establish ‘standards’ which will be helpful to people who want to develop breeding, management or feeding strategies for high genetic merit cows. Whereas the performance of high and average genetic merit cows on two different feeding systems has been presented before (Veerkamp et al. 1995), the aim of this study is to define if some of the advantages of high genetic merit

Three sources of sensory data: cow's individual rumination duration, activity and milk yield were evaluated as possible indicators for clinical diagnosis, focusing on post-calving health problems such as ketosis and metritis. Data were collected from a computerised dairy-management system on a commercial dairy farm with Israeli Holstein cows. In the analysis, 300 healthy and 403 sick multiparous cows were studied during the first 3 weeks after calving. A mixed model with repeated measurements was used to compare healthy cows with sick cows. In the period from 5 d before diagnosis and treatment

AbstractThe aim of this Research Communication was to apply the data mining technique to classify which environmental factors have the potential to motivate dairy cows to access natural shade. We defined two different areas at the silvopastoral system: shaded and sunny. Environmental factors and the frequency that dairy cows used each area were measured during four days, for 8 h each day. The shaded areas were the most used by dairy cows and presented the lowest mean values of all environmental factors.

In addition, cultures were performed for Campylobacter sp., Ureaplasma sp., Mycoplasma sp., Tritrichomonas foetus, and fungi. All 106 samples contained mixed aerobic bacterial cultures.

It was shown that a 12-hour interval between two milkings was good for high-yielding cows, with a steady increase in milk production during the first half of lactation.

Abstract:

Original Objectives. The overall goal is to develop methods to increase pregnancy rate in lactating dairy cows exposed to heat stress through methods that minimize damage to the oocyte and embryo caused by heat stress. Objectives were as follows: (1) examine the protective effects of melatonin on developmental competence of oocytes exposed to elevated temperature in vitro; (2) test whether melatonin feeding can improve developmental competence of oocytes in vivo and, if so, whether effects are limited to the summer or also occur in the absence of heat stress; and (3) evaluate the effectiveness

Abstract:

The overall goal was to identify survival factors that can improve pregnancy success following insemination or embryo transfer in lactating dairy cows exposed to heat stress. First, we demonstrated that oocytes are actually damaged by elevated temperature in the summer. Then we tested two thermoprotective molecules for their effect on oocyte damage caused by heat shock. One molecule, ceramide was not thermoprptective. Another, insulin-like growth factor-1 (IGF) reduced the effects of heat shock on oocyte apoptosis and oocyte cleavage when added during maturation. We also used lactating cows ex

Abstract:

The objectives were: 1) to develop a practical method for improving conception rates of dairy cows by administering progesterone during the critical period of the luteal phase prior to first insemination, 2) to determine which cows respond best to such a progesterone treatment, and 3) to determine physiological changes that are associated with this treatment. Experiment 1, conducted in the US and Israel, tested three treatment protocols. Holstein cows: 1) served as controls, 2) received two injections of prostaglanding F2a (PGF) 14 days apart, or 3) received two PGF injections and were inserte
