Übersetzung für "Early lactation" in Deutsch

Every third dairy cow is affected by subclinical ketosis during early lactation!

The excretion of histamine in milk has not been studied in animals, but at maternotoxic doses in rats, offspring showed slight toxicity during early lactation (see section 5.3).

A reduction to 50 % for animals in dairy production for a maximum period of three months in early lactation shall be allowed;

High performance dairy cows run through a period of negative energy balance during early lactation which leads to an impairment of the immune system.

Here we are particularly interested in the metabolism but also in the immune system and therefore the phases of calving and early lactation that are especially stressful for animal health.

So far, the effect of numerous metabolites and hormones on the reduction of feed intake has been described in literature, however, until today there is only marginal knowledge on endogenous signals significantly promoting feed intake of ruminants during the early lactation period.

It occurs as subclinical hypocalcemia (calcium deficiency) around the time of calving and during early lactation.

If too many cows get an attention for total weight loss during early lactation, this indicates that the transition period is not optimal and that animals are in a too severe negative energy balance (NEB).

During the transition from late pregnancy to early lactation, high producing dairy cows usually experience a negative energy balance due to insufficient increase in feed intake and the enormous energy requirements for milk production.

The nutritional management of dairy cows has a direct influence on fertility performance, particularly in early lactation.

By pursuing these aims we expect to elucidate the physiological regulation of endocannabinoid-mediated signaling during the transition from late pregnancy to early lactation, and to depict ways of improving energy balance and health status of early lactating dairy cows.

Moreover, the role of deoiled lecithin in boosting feed conversion rates in weaners was examined and new results were obtained about the effects of fractionated feed fats on dairy cows at the early and mid lactation stages.

As a result, the aim is to reduce energy deficiency by achieving the highest possible dry matter intake during the transition and early lactation stages.

A proactive herd monitoring program is an important and valuable tool: routine screening of every cow after calving for premature detection of - herd problems as well as single animal problems during early lactation - and taking measures in-time and initiating improvements in herd management!

Whereas in recent years the trials conducted in North America focussed on the use of fractionated feed fats during mid and late lactation using corn based diets, B+S has now gained new insights into the optimum dosage of fractionated feed fat during early and mid lactation of grazing cows.Current research activity and outlook At present Berg + Schmidt is working with Cornell University, New York State, on trials to assess the bio-availability of rumen by-pass methionine.

As few as 10% of inseminations in “heat stressed” cattle result in pregnancies, and cows that are stressed in early lactation show poorer fertility 2-3 months later due to impaired follicular development.
