Weekly Farm Summary 5th May 2022

Farm-system impacts of: Kalve vs Fodder beet for winter AND reducing N loss to water by 30%. 

Cows & Milk Analysis

Business Area Current Status
Feed As soil temperatures hold around 13 deg C, pasture growth is at or above the feed budget target. Baleage will be removed from all herds except the LI FB herd. FB allocation will be reduced to ensure we have enough beet till the end of lactation.
Milk Production Production continues to hold around 1.2 kgMS for all herds. 91 cows were dried off this week. Interestingly SCC has mirrored rainfall events in the FB herds that are grazing beet following milking each day. The LI FB herd hit 1000 kgMS/ha this week, taking the farm average to 1116 kgMS/ha.
People Planning is underway for an end of season event before Christian moves on.
Animals Total of 104 cows are now dried off, with a range of treatments used. Planning has been completed for feeding any of the 40 culls still on farm post 1 June. Increase in lameness incidents over the past week, with occurrences across all farmlets.
Environment Effluent applications are being reviewed weekly in alignment with soil temperature and moisture levels. Target pond level at dry off is 25% to 30%.
Wintering Winter plans have been finalised by Louise and Billy. Baleage will not be pre-laid out in the transition areas of the paddocks, instead it will be done on the day to ensure wastage does not occur and bales can be placed out for easy cow access in the smaller transition breaks.
Research We have just completed the last round of N intake estimates and pasture quality sampling for the season. Unfortunately, an oven malfunction has impacted the calculation of yield in some of the recently sampled paddocks.

Feed

Principles of Pasture Management this week

Feed Quality & Quantity As strong pasture growth post the dry period continues, supplementary feed for all herds is reducing to ensure we optimise pasture quality heading into winter. Growth rates and increasing APC suggests there is enough feed available to significantly reduce supplementary feed inputs. Dry matter % is currently 16.6-19.5%, crude protein 19-23% and ME 11-11.3 MJ/kg DM.

Lucerne baleage has been removed from the diet as the quality of the last load was poor and was potentially impacting milk production.
Growth rate Management The LI Kale herd has a slight pasture surplus this week due to having the most cows dried off. If required paddocks at the top of the wedge will be stepped over this week to allow them to reach the required pre-graze target for 3 days per paddock. The recently dried off cows will follow herds through paddocks where residual has not been met to clean up left over feed. They will spend no more than 2 days per paddock & will be supplemented with baleage and straw.
Nitrogen Strategy Effluent applications are being reviewed weekly, however at current soil temperatures and moisture levels we will continue with applications until conditions change.

Milk Production

Principles of Milk production management this week

Milk Production Milk production continues to fluctuate between 1.2 and 1.3 kg MS/cow/day across all herds.

SCC in the fodder beet herds has fluctuated this week coinciding with rainfall events. We attribute this fluctuation to the grazing of beet in the crop paddock immediately after milking.

All herds are behind last seasons production with the Std FB herd being the furthest below.
Key influences on milk production It will be interesting to see how the herds respond to the decrease in supplementary feed, particularly the removal of baleage for most and reduction in inshed feeding. Pasture quality appears to have improved with more green leaf and fewer paddocks with significant dead material in the base.
Cow Management 91 cows dried off this week and the remainder booked for the 23rd and 24th May. Individual animals may be dried off before then based on milk yield, SCC, lameness or mastitis risk.
