Key Decisions: this week

  • We had some lovely rain this week to help freshen up pastures and increase soil moisture content as soils were starting to get a bit dry. The cows have been leaving good residuals in paddock, though the Std. FB & LI FB have been a bit tight in some. The gap between demand and supply will continue to be filled with inshed feeding to the Kale and baleage to the FB farmlets.
  • Continuing with final round of N fertiliser across all farmlets following behind the cows– Std farmlets at 25 kg N/ha as Ammo31; LI farmlets at 15 kg N/ha as a special ammo brew to match sulphate inputs across the systems. Targeting 7 kg sulphate/ha
  • The R1s at the runoff were brought in to be drenched and weighed. The average weight was 163kg, with a range of 119kg to 190kg. The calves at the grazier were weighed 1.5 weeks ago at an average of 164kg so it is great to see that the additional feeding of PKE to the smaller mob at home is helping catch them up to their bigger compatriots that were sent out to grazing.
  • All crops have now received their side dressing of N fertiliser. We have noticed some variation in kale crop height between pdks and wondering if there will be a yield variation when we do crop yields in 2 weeks. Some kale paddocks also have significant white butterfly damage around the edges of the crop and we are consulting with our agronomist about this.
  • We have settled on our winter mob sizes and once complete our first crop yields in 2 weeks we can do a forward prediction for winter feed supply and amount and location of baleage. Once our final load of baleage arrives next week we will do quality and dry matter tests.
  • With increased soil moisture, conditions are starting to improve for soil aeration. We will schedule over the next few weeks which paddocks will be appropriate for aeration, being very conscious of the correct soil conditions before going ahead and not doing all the paddocks at once to avoid a potential pasture deficit as growth will be impacted post aeration.
  • In the next few weeks we will be identifying next year’s winter paddocks so that we can use them for springer paddocks. Once these springer paddocks are identified we will strategically graze them so that they go into winter at the appropriate cover to meet the spring feed budget requirements.
  • Our growth rates continue to track above last season with a clear difference in growth rates between Std. and LI farmlets. Our APC has been tracked against target autumn APC to predict our autumn feed budget. As you can see below we are tracking above our target, though these target values are conservative. Daylight hours, temperatures and growth rates have been dropping so we expect APC to fall however we still have some autumn fertiliser to be applied to boost growth and can remove culls to decrease demand.

General Notes:

  • We had booked in x40 culls cows for early March but due to space we sent away x25 instead. The first round of culls are the lowest producing empties and discretionary culls from each herd. More culls went from the FB herds to reduce the demand for baleage until the fodder beet is ready for grazing.
  • Milk production has dropped off from the end of last week for majority of the farmlets with a larger gap forming between LI FB farmlet. The Std. Kale has crept up a bit, and the Std. FB are showing the impact of a few tight feds.

  • The difference in season to date production between kale and fodder beet herds continues to widen (Figure 3).

Animal Health

  • Last week we mentioned that x6 cows (x2 Std Kale, x2 LI Kale, x2 LI FB) were identified as potential Johnes from milk tests and were to be blood tested to confirm status. Results came back with x5 being high positive or positive and one being suspicious. It was recommended to cull the positives, and if short on cull cows, ear tag the suspicious one and not keep her calf or feed her colostrum/milk to calves to minimise spread. Given our low not in calf rate we have decided to cull the one coming back as ‘suspicious’. You can read more about Johnes management here: Johne’s Disease Management – DairyNZ
  • A cow we had health issues with and dried off a few weeks ago was not improving so the decision was made to euthanise and autopsy her. She had a number of secondary infections including pneumonia.

People Management and Visitors

  • We had a great field day this week at SDH talking through our results around N leaching, the wintering behaviour trial, and cropping techniques. We also had some great farmer speakers talking through their wintering practices. Thanks to all that spoke and attended, with over 100 people sharing knowledge! We will have the handout up online in the next few days or contact Louise Cook or Nicole Cochrane to have it emailed.

Research on-farm

  • The research tech team have been busy with pasture N intake week and monthly crop yield commences later in March. Looking into April they will be busy with BCS training and animal sampling.
  • The summer botanical composition analysis on all paddocks has been completed with the LI paddocks continuing to have a higher proportion of clover and lower proportion of ryegrass than the Std paddocks (Figures 5 and 6). There has been a steady increase in clover content in the Std FB paddocks
  • Interesting the paddock with the highest clover content of 58.5% was a Std FB paddock established in new grass last year. 70% of these paddocks below to the LI farmlets.
  • Almost 30% of paddocks had more than 20% clover and 20% had less than 5%
  • Because of subtle differences in post grazing height between paddocks and farmlets the samples for dissection were cut to ground level hence the higher dead content than what we normally see in pasture dissections.

General Farm Systems Information

The project farm systems comparison has been designed to better understand crop-based wintering in relation to consequences for environmental impact and profit

  • The four herds are split evenly on age, BW / PW, calving date and breed to ensure the herds are as even as possible.
  • Each herd allocated a farmlet corresponding to their herd tag colour Green, Blue, Yellow and Pink.
  • Farmlets have paddocks allocated so each herd has equal walking distance from the shed and the same proportion of each soil type and equal proportions of pastures in the FVI trial (forage value trial – refer web site section on research).

Research Proposals

The SDH welcome research proposals for any sampling or research on the SDH, these are assessed by the Research Advisory Committee (RAC). Just send your request or ask for information via louise.cook@southerndairyhub.co.nz
