Closing remarks

Introduction

(Explanation of current problems and economic impact)

Frank van Eerdenburg, Utrecht, The Netherlands

Oestrous behaviour in heifers and lactating dairy cows under a pasture-based production system

(A description of the behavioural expression before ovulation and the importance of the individual behavioural components in relation to their predictive value for the moment of ovulation will be presented)

Daniel Cavestany, Montevideo, Uruguay

Heatwatch oestrus detection system

(This is an automated, radio-telemetric, mounting detection system. The system can be used to detect cows in oestrus. Furthermore, the exact time of the first mount is recorded.)

Michael Diskin, Teagask, Ireland

Coffee break

Pedometers

(Pedometers record the activity of a cow automatically. The systems currently in use have difficulties with sensitivity and accuracy. However, new pedometer systems give better results and allow better timing for insemination)

Frank van Eerdenburg, Utrecht, The Netherlands

Right moment for insemination

(The right moment to inseminate the cow after detection and the chances of getting the cow pregnant are presented.)

Judith Roelofs, Wageningen, The Netherlands

Possible causes for the diminished expression of oestrous behaviour

(New and older data will be presented that might trigger the discussion about why cows do not show their oestrous behaviour like they used to do.)

Frank van Eerdenburg, Utrecht, The Netherlands

Occurrence and diagnosis of abomasal displacements in dairy cows

Klaus Doll, Clinic for Ruminants and Swine, University of Giessen, Germany

Introduction in the laparoscopic procedure for treatment of left and right sided abomasal displacements

Torsten Seeger, Clinic for Ruminants and Swine, University of Giessen, Germany

Treatment of cows with abomasal displacement to the right / abomasal volvulus

Klaus Doll and Torsten Seeger

Influence of energy balance on gene expression in the liver and reproductive tract of lactating cows and consequent effects on fertility

Epidemiological approach of nutritional factors influencing dairy cow fertility during the dry and post-partum periods

Manipulating the dry period and regimes to minimize NEB; consequences on milk production and reproductive activity

R. Grummer, R. Watters, M. Wiltbank, N. Silva Del Rio, P. Fricke

Short communications and summary
Relationships between BCS/Metabolic aspects and reproductive activity from both beef and dairy cows in subtropical areas and or under “More difficult environmental conditions”

Basis of ultrasound

Ovary: the CL (CL with cavity and compact CL); the follicular dynamic (use of ultrasound for improving the CR in synchronization programmes); ovarian cyst degeneration

Uterus: uterus in different stage of the cycle; metritis, endometritis, pyometra, mucometra
