Early Lactation

Previous articles have emphasised the importance of good feeding and management during the transition period around calving, so early lactation management should build on a good transition foundation.  Early lactation is a stressful time for dairy cows, as they recover from calving, rapidly increase milk production while losing body condition, and prepare for the next [...]

Benefits of Good Transition

The risks of disease and metabolic issues are greatest during the transition period (3-4 weeks either side of calving), which is dominated by a series of adaptations as cows move from pregnancy to lactation.  As much as 80% of all health issues related to this period. Establishing successful lactations requires an integrated transition management and [...]

Rearing More Productive Heifers

It has been demonstrated that better grown calves and heifers have higher first lactation and lifetime production than less well grown ones.  What is less certain is the extent to which the benefits of early rumen development remain through to and after calving, with heifers reared off farm. This was tested in an on farm [...]

Rearing More Productive Heifers – Trial Review

Rearing calves well has long been recognised as important in the development of productive heifer replacements.  This concept has been extended more recently to studying the benefits of early rumen development on subsequent growth and milk production. Agrifeeds/Agritrade have promoted an early rumen development feeding programme using an extruded pre-starter feed RumenX®, and have conducted [...]

Managing Cows During the Dry Period

Last month’s article focussed on feeding cows to achieve calving body condition targets prior to drying off.  This month’s article covers feeding and management during the dry period prior to the transition to calving. Most dry cows are wintered on pasture or crops off the milking platform, with the aim to maintain or gain condition [...]

Maintaining Pregnancy

Local trials have demonstrated early embryonic loss is the major cause of empty cows, being a financial drain on farming businesses, through higher replacement costs and lost production.  The forecast intense El Niño may lead to higher than usual empty rates this year, if farmers do not ensure they provide sufficient high quality feed during [...]

Colostrum Quantity & Quantity on Replacement Performance

Recent research has demonstrated how plane of nutrition and diet during pregnancy can affect colostrum production, milk yield and calf health.  Feeding cows to match energy, protein, mineral and vitamin requirements during pregnancy, supports production of colostrum and milk components, essential for the health and development of newborn and growing calves. Research in both cattle [...]

Importance of Good Transition

It is important to include fixed (land, interest) and variable (seed, fertiliser, sprays) costs in growing and harvesting pasture or crops to properly evaluate cost benefits of using inoculants when preserving forages. Effective lactic acid producing inoculants have been demonstrated, in controlled trials, to reduce dry matter losses by 5->10%, under good ensiling conditions.  Inoculant [...]

Benefits of Good Transition

Some of the biggest opportunities to increase production efficiency and reproductive health come from supporting dairy cows as they “transition” from late pregnancy to early lactation.  Whilst many traditional systems have taken a “hands off” approach to the transition period it is now generally considered to be the most critical time of the year, with [...]
