Positive Effect

The objective of our research was to evaluate the effect of some factors on the embryonic mortality of Holstein-Friesian dairy cows in a herd. Monitoring was conducted in the course of three years (2006–2009) at a level of (9330–8970) kg/dairy cow per lactation. We monitored the reproduction parameters of 209 dairy cows (1st to 8th lactation). Ultrasonography was used to diagnose gravidity, and/or embryonic mortality, in each cow 6 times, at regular 4-day intervals between days 22 and 42 after insemination. We analysed the effect of 3 factors on embryonic mortality: age, body condition score and season of the year at the time of insemination. Embryonic mortality relative to the age of the female was significantly the lowest (20.69 %) in cows aged 42 to 47 months (3.5–3.9 years); high embryonic mortality (45.46 %) was recorded in the youngest females of 24 to 29 months of age (2.0–2.4 years). The results indicated that the body condition score of the cow at the time of insemination had a statistically significant (P > 0.01) effect on embryonic mortality (EM). Embryonic mortality was the lowest when the body condition of the cow was “ideal”, i.e. 5 points of the BCS (at the most 9 points). The season of the year when insemination was carried out had a positive effect on embryonic mortality.

Effect Of Feeding

High levels of dietary concentrates are often used to support milk production and it is important to investigate ways to feed them efficiently. Fats have the greatest energy density of any feed ingredient and the inclusion of protected fats in the dairy cow ration enables a high energy but balanced ration to be fed. The aim of this trial was to investigate the effect of feeding different levels of Megalac (Volac International Ltd, Herts) to dairy cows and to compare milk yield, milk composition, fertility and body condition score (BCS).

Welfare Measures

Animal welfare is a hot topic among consumers, producers and researches nowadays. The major welfare problems of dairy cows are mastitis, lameness, and any conditions which lead to impaired reproduction, inability to express normal behaviour, emergency physiological responses or injury. This paper summarizes preliminary results of project taken in 27 Hungarian dairy farms evaluating general animal welfare. The most important areas for improving animals? wellbeing are related to facilities and comfort of resting. Findings include slippery floors, cows struggling laying and standing in cubicles. Other measures include hair loss, hocks, neck rail injuries and number of thin cows (Body Condition Score 1 and 2). Mouldy silage and low quality of other feedstuff was also found. In conclusion, preliminary results confirm strong demand for monitoring farms and discussions with managers and farmers about welfare measures needed to be taken on farms immediately.

Feeding Systems

The ability of high-yielding modern dairy cows to perform in the range of systems found on UK dairy farms, and to be profitable and sustainable, needs investigating. As part of a project to study the robustness of such animals, milk-progesterone profiling was used to investigate the reproductive performance of two genotypes of dairy cow on two production systems (Pollott and Coffey, 2006). In this paper differences in fertility between genotypes and systems was investigated using energy balance (EB) and body condition score (CS) as explanatory factors.

AbstractOver-conditioned dairy cows, classified by body condition score (BCS) and backfat thickness (BFT) are less able to metabolically adapt to the rapidly increasing milk yield after parturition. Based on serum metabolome and cluster analyses, high BCS cows (HBCS) could be classified into metabotypes that are more similar to normal (NBCS) cows, i.e., HBCS predicted normal (HBCS-PN) than the HBCS predicted high (HBCS-PH) cows—similar to the concept of obese but metabolically healthy humans. Our objective was to compare muscle metabolome and mRNA abundance of genes related to lipogenesis and lipolysis in adipose tissue between HBCS-PH (n = 13), HBCS-PN (n = 6), and NBCS-PN (n = 15). Tail-head subcutaneous fat was biopsied on d −49, 3, 21, and 84 relative to parturition. Potential differences in the oxidative capacity of skeletal muscle were assessed by targeted metabolomics in M. semitendinosus from d 21. Besides characteristic changes with time, differences in the mRNA abundance were limited to lipogenesis-related genes on d −49 (HBCS-PH > HBCS-PN). The HBCS-PH had more than two-fold higher muscle concentrations of short (C2, C4-OH, C6-OH) and long-chain acylcarnitines (C16, C18, and C18:1) than HBCS-PN, indicating a greater oxidative capacity for fatty acids (and utilization of ketones) in muscle of HBCS-PN than HBCS-PH cows.
