2 Introduction Dairy production in Ireland Nutritional issues of the early lactation dairy cow Recent energy balance experiments conducted at UCD Effect of supplementary concentrate type on energy balance in the early lactation, pasture fed dairy cow Effect of dietary CP and starch content on energy balance in early lactation dairy cows Conclusions Overview of Presentation

3 Dairy Production in Ireland Largely seasonal production system 1.1 million dairy cows 5,000 kg average milk production Contributes 2.7 billion to Irish exports However, still room for improvement Replacement rate is 25% 15% are replaced due to infertility Calving interval is 394 days

4 Nutritional issues of the early lactation dairy cow Early lactation is a challenging period for the dairy cow Important to explore dietary strategies that reduce these challenges Optimising DMI is important in improving energy balance Moderating milk yield through dietary CP may also improve energy balance

5 Manipulating CP intake in the pasture fed early lactation dairy cow

6 Basis for Experiment Pasture is the most abundant forage source available to Irish dairy farmers However Chemical composition of grass can vary considerably This flux in nutrient supply may be detrimental to the animals health Therefore Concentrate supplementation is often required, but Concentrate type will be important

7 Materials and Methods Randomised block design Day 1 until day 100 postpartum 11 animals per dietary treatment Balanced for parity, milk yield, constituent yield and calving date Blood samples harvested on weeks 2 through to 5 postpartum Milk samples taken weekly Energy balance determined during week 6 post partum

8 Concentrate Treatments Supplements were fed twice daily during milking (6kg total) 4 supplementary concentrate treatments HP(180g CP kg -1, rolled barley) LP(140g CP kg -1, rolled barley) LP+ HMBi (140g CP kg -1, rolled barley + supplementary methionine (HMBi)) LP Corn (140g CP kg -1, ground maize grain)

9 Chemical Composition of diets offered HP LP LP+HMBi LP Maize Pasture DM (g kg -1 ) Energy (UFL) Crude protein PDIA PDIN PDIE NDF ADF ADL Ash Starch

20 Glucose (mmol L -1 ) Glucose b b ab a 0 Concentrate Type HP LP LP+ HMBi LP Maize a vs. b (P < 0.05)

21 Conclusions Milk yield was reduced where LP was offered. However ECM was not different Lower BHBA and blood urea N indicated a more favourable metabolic status where low CP concentrates were offered The use of maize grain or supplementary methionine in low CP concentrates improved milk production without impacting on metabolic status

22 Dietary manipulation of crude protein and starch content affects energy balance in early lactation dairy cows

23 Basis for Experiment Early lactation is a challenging period for the dairy cow Reducing dietary CP intake can improve EB Similarly providing glucogenic diets can improve the metabolic status of the diary cow However, the simultaneous application of these strategies has not been tested to date

24 Materials and Methods Randomised block design Day 1 until day 63 postpartum 10 animals per dietary treatment Balanced for milk yield, constituent yield and calving date Blood samples harvested on days 0, 7, 14, 21, 28, 35 and 63 Milk samples taken weekly Post experiment All animals offered a pasture based diet

25 Dietary Treatments Diets were offered once daily as a TMR 1. High CP low starch TMR (HP-LS) 15% CP 6% Starch 2. Low CP high starch TMR (LP-HS) 12% CP 28% Starch Diets were iso-energetic (1.05 UFL/ kg DM)

26 Chemical Composition of diets offered HP-LS LP-HS Composition (% unless stated) DM UFL/ kg DM CP NDF PDIA PDIN PDIE ADF ADL NDF for Ash Starch

32 Energy Balance (UFL/ d) Energy Balance over the Duration of the Experiment Week of Lactation HP-LS LP-HS Diet P = 0.02 Week P < 0.01 Diet x Week P = 0.75

33 BCS Units BCS at Calving and Day P = 0.47 BCS at Calving HP-LS Loss = 0.2 BCS P = 0.36 BCS at d63 LP-HS

34 Blood Metabolites

35 BHBA (mmol/ L) Beta Hydroxy Butyric Acid P = HP-LS Diet LP-HS

36 NEFA (mmol/ L) Non Esterified Fatty Acids P = HP-LS Diet LP-HS

37 Glucose (mmol/ L) Glucose P = HP-LS Diet LP-HS

38 Conclusions Offering early lactation dairy cow a low CP, high starch diet improves energy balance Reductions in milk yield observed during early lactation did not affect 305 d lactation yields Blood metabolites did not indicate a severe metabolic challenge in this experiment

39 Overall Conclusions Regardless of production system, the maintenance of DMI is key in maintaining a more positive energy balance Reducing CP intake moderates milk production and reduces the urea burden on the animal, thus reducing energy demands Further work is required in pasture based production systems to determine the extent to which CP can be reduced Work is also required to determine the lifetime effects of these strategies on the survival of the dairy cow
