Grass growth has started to slow, falling 21kg DM/ha/day to an average of 79kg DM/ha/day.
Declining growth rates will mean that it will be important to monitor grass supply closely to ensure potential shortfalls are identified as early as possible as the summer progresses.
We are fast approaching the summer solstice and daylight hours are still increasing leading to an increase in the potential grazing hours available.
Predicted grass DMI has risen by 1.8kg DM/day to 13.5kg DM.
This has underpinned an increase in the potential milk yield from grazing, from M+ 10.8 litres/day last week to M+ 14.9 litres/day this week. This is driven by grass availability and grazing hours in daylight as grass quality is lower than the seasons average with ME at only 11.4 MJ/kgDM.
The higher NDF content and NutriOpt Fibre Index will help support butterfat.
The average crude protein content of the grass samples sent into the Trouw Nutrition GB lab has fallen slightly from last week to 20.77%, which is close to the 6 year average of 20.94% for this time of year.

Grass Watch Update for Week Commencing 13th May 2016
The improved temperatures this week have increased average grass growth rate, which has accelerated to 81 kg DM/ha/day up 40 kg DM/ha/day from last week. The increased temperatures have also seen the temperature humidity index increase to 71, this is the upper limit for mild heat stress.
A combination of a reduction in the average Dry Matter from 21.3 % to 19.3 % and average Est ME from 12.01 MJ/Kg DM to 11.83 MJ/kg DM this week has seen the potential milk yield from grazing fall by 4.2 litres per day down to M+11.6 litres.
This highlights the influence that changes in grass dry matter has on bite dry matter weight, intake and ultimately potential milk yield from grazing. The falling ME also highlights that close attention should be given to silage crops and cutting date to strike a balance between both yield and quality.
This week’s Crude Protein level at 21.1% continues to remain lower in comparison to last year at 22.4% and the 6 year average of 23.5%. This may reflect alterations in normal fertiliser applications due to the challenging conditions experienced over the last few months.
Having the right applicator whether injecting, drenching or pouring on is critical to overall good treatment result. The risks using the wrong applicators are many and following a few small guidelines can improve your animal health practice.
One thing’s certain about 2016 worm threat: It’s unpredictable!
From most areas of the UK, feedback suggests that last year was one with low to moderate roundworm burdens, according to Zoetis vet Dave Armstrong. “Where this was identified using good diagnostics,” he says, “economies from using fewer wormer treatments were possible with manageable risk rather than a fingers crossed approach.
Lamb growth is at its most efficient in the first 10 weeks, so the quicker you are able to rear your lambs to target deadweight, the more efficient the enterprise and in turn you will be able to reap the benefits of selling on to an earlier market.
Colostrum is often described as ‘liquid gold’ as the fuel for life. One secret to rearing healthy lambs, and for future production, is to make sure each lamb receives enough colostrum. Ad-lib feeding can often see lambs perform and grow better than they would had they been left on their mothers.
Finishing beef cattle on high starch diets has many known benefits not least being increased growth rate. With the current price of cereal feeds, it is currently an economical approach which can also improve carcass conformation and hence give higher returns per kilo.
Regular vaccination of your ewes throughout the year is a very important part of flock management. Never is it more important than in the period prior to lambing, this is crucial for ewe’s producing colostrum to pass on immunity to newborn lambs.
Pre-season preparation is key to minimising problems, reducing losses and achieving a higher lamb yield per ewe, which eventually will lead to improved daily liveweight gain and increased margin. With lower lamb prices last season, there should be no shortcuts taken ahead of the current crop of lambs.
Lambing time is a crucial period for sheep farmers. Maximising the health and productivity of the future flock is vital to the success and sustainability of your farm. Preparation is key; therefore our sheep production team has produced this guide providing technical and product support for every stage of the lambing process.
Wynnstay aim to support the needs of the British sheep farmer and have produced this guide in the hope that we can increase the sustainability of your business. We have a small selection of lambing sundries available to purchase online as well as in your local store.
