Low Incidence

Norway has adopted a multi-trait selection programme within its Norwegian Red (NR) dairy cow population for over thirty years, in contrast to breeding programmes with the Holstein-Friesian (HF) breed, which have, until recently, focused primarily on milk production. As a result, evidence from Norway suggests a dairy cow population with high levels of fertility and a relatively low incidence of mastitis. Consequently, there is considerable international interest in the NR breed as a means of overcoming some of the fertility, health and longevity problems that currently exist within the HF breed. To examine the potential of the NR breed, an experiment was established on 19 commercial dairy farms to compare the production, fertility and longevity of animals of the NR and HF breed across a range of production systems.

Earlier work showed that red clover silage has considerable potential for milk production (e.g. Thomas et al., 1985), though low digestibility and difficulties ensiling clovers were seen as problems that needed to be addressed. Advances in legume breeding and conservation technology as well as a renewed emphasis on extensive organic production systems within Agenda 2000 meant that it was timely to reconsider the potential of legume silages for milk production.

Breeding Programmes

Breeding goals differ for different breeds of dairy cattle. For example the breeding programmes for Holstein-Friesian (HF) animals have been based primarily on improved milk production with little emphasis on functional traits such as fertility. In contrast, Norwegian (NC) dairy cattle have been bred using a multi-trait selection procedure for 25 years. These differences in selection procedures for the two breeds may have major effects on overall herd output and profitability with the forage-based systems of milk production employed in Northern Ireland. The objective of the present paper is to present the effects of two levels of nutrient input on food intake and utilisation, and animal performance of the two breeds, with diets based on grass silage during the first and second lactation.

The Impact

SUMMARYThere is little empirical evidence to indicate that dairy cow live weight affects the extent of soil damage at the hoof-soil interface during grazing on poorly drained permanent grassland. In the present study the impact of Holstein-Friesian (HF) dairy cows with a mean (±standard deviation) live weight of 570 (±61) kg were compared with Jersey × Holstein-Friesian (JX) with a mean live weight of 499 (±52) kg each at two stocking densities: mean 2·42 ± (0·062) and 2·66 (±0·079) cows/ha. Soil physical properties (bulk density, macroporosity, gravimetric water content, air-filled porosity, penetration resistance and shear strength), poaching damage (post-grazing soil surface deformation and hoof-print depth), herbage yield and milk production were measured throughout 2011 and 2012. Soil physical properties, post-grazing soil surface deformation and herbage production were not affected by dairy cow breed or by interactions between breed and stocking density. Hoof-print depth was higher in the HF treatments (39 v. 37 mm, s.e. 0·5 mm). Loading pressure imposed at the soil surface was the same for both breeds due to a direct correlation between live weight and hoof size. Poaching damage was greater at higher stocking density. Using the lighter JX cow offered little advantage in terms of lowering the negative impact of treading on soil physical properties or reducing poaching damage and no advantage in terms of herbage or milk production compared with the heavier HF cow.

In temperate regions of Europe where grass grows for most of the year, grazed pasture is the lowest cost feed for milk production. Grazed pasture can make a contribution to dairy cow feeding systems in other parts of Europe, but is less important. While there are many challenges to maintaining or increasing the proportion of grazed grass in dairy cow diets, there are also opportunities to increase its contribution. Grass use and quality can be challenging for several reasons, including the cow and sward interaction, and factors influencing dry matter intake. Adapting grazing management strategies can provide opportunities for incorporating grazing and perhaps increase grazing in dairy cow milk production systems. Pasture management tools and techniques offer the opportunity to increase herbage use at grazing. While there are many benefits of grazing including economic, environmental, animal welfare and social, there are also the challenges to maintaining grazed pasture in dairy cow diets. The objective of this paper is to present an overview of the challenges and opportunities for grazing in dairy milk production systems.

Current Systems

The UK dairy industry has entered a period of rapid increase in cow genetic merit. Feeding and management during the rearing period will influence the extent to which the genetic merit of these animals is realised. Current systems for rearing dairy herd replacements are based on research undertaken in the 1960's and 1970's with animals of lower genetic merit. High genetic merit Holstein Friesian animals have an increased live weight and frame size at maturity compared with their medium merit contemporaries, which may have implications for the optimum weight at first calving. The aim of this study was to determine the effect of rearing regime, in terms of diet offered and target calving weight, on first lactation performance of high genetic merit heifers over a range of milk production systems.

In Northern Ireland, grazed grass is the main diet offered to dairy cattle throughout the summer months. Whilst the Holstein-Friesian (HF) dairy cow is extremely efficient at converting grass into milk, there is evidence that the incidence of infertility in this breed is increasing (Mayne et al. 2001). This may reflect the fact that the breeding goals for the HF breed have been based primarily on selection for milk production with little emphasis for other traits such as fertility or health. In contrast, Norwegian dairy cattle (NC) have been selected using a multi trait index, with less emphasis on milk production and inclusion of other fertility and health traits. The overall objective of the present study was to evaluate the effect of varying stocking rate at pasture on performance of these two contrasting breeds.

Degradable Protein

Ruminants may absorb large quantities of ammonia resulting from microbial fermentation and incomplete capture of rumen degradable protein (Huntington, 1984, 1987). Detoxification of this ammonia by ureagenesis in the liver involves the use of aspartate, and although this can be derived from ammonia via glutamate, it may be drawn from the general body amino acid pool. If the latter occurs, the availability of amino acids for milk production may be reduced, leading to a reduction in the quantity and/or quality of milk produced. This experiment was designed to investigate the effect of infusing ammonia into the duodenum of dairy cows on the quantity and quality of milk produced.Four multiparous Holstein-Friesian dairy cows fitted with duodenal cannulae were given one of two experimental treatments based on duodenal infusions in a changeover design with three periods (the last period of a four period design was not completed). Duodenal infusions were chosen to avoid direct effects on rumen parameters.
