	abstract = {<p>The objective of this study was to use the Large Ruminant Nutrition System simulation (LRNS) model to evaluate inclusion of different proportions of fodder beet (FB) with several feed supplements to determine if these dietary combinations meet the nutrient requirements of dry cows and growing one-year-old (R1) heifers over winter. The LRNS simulations demonstrated deficiencies in Ca and P when diets contained 60 and 80\% of FB, especially for dry cows up to 21 days before calving and in R1 heifers. When FB comprised 60-80\% of the diet of R1 heifers, there was insufficient metabolisable protein to support maximum average daily gain and insufficient physically effective neutral detergent fibre (peNDF) in diets containing over 60\% FB. Diets containing more than 40\% FB had a negative rumen degraded protein balance (RDPB) and an excess non-fibre carbohydrate (NFC) concentration. Recommendations based on this modelling are for a maximum of 60\% FB in diets and forage supplements must provide sufficient crude protein (CP) as well as supplementation of Ca for R1 heifers and dry cows up to 21 days before calving and P for both dry cows and R1 heifers.</p>

	abstract = {High yields, consistent quality and emerging environmental benefits make fodder beet (FB) an important feed in South Island dairy
systems. However, these benefits may be negated by animal-health issues associated with some FB-feeding regimes. To quantify
the range and prevalence of feeding regimes, a telephone survey focussing on practices in 2018 was conducted in Canterbury,
Otago and Southland. Of the farmers surveyed, 69\% fed FB, 24\% had never fed FB and 8\% of farmers had stopped feeding FB.
The most frequently cited reasons for having stopped feeding FB were animal-health issues, cost and management challenges.
Most (82\%) respondents feeding FB determined allocation by yield and break area. Almost all farmers (98\%) transitioned cattle
on to FB, over an average of three weeks. Of those that fed FB to non-lactating cows in winter, the mean allocation was 10.3 kg
DM/cow/day (66\% of the diet), and 12\% fed FB ad libitum. A greater proportion of herds fed FB (41\% of herds) reported metabolic
issues (>5\% of the herd affected) compared with herds not fed FB (23\%). This survey is valuable to inform future research and
reinforces the need to continue investigating animal-health issues associated with FB-feeding, with an emphasis on metabolic issues.
