Use of a glycogenic precursor during the prepartum period and its effects upon metabolic indicators and reproductive parameters in dairy cows
The aim was to evaluate if 1-2 propanodiol plus calcium propionate (glycogenic precursor) supplementation during the transition period in high yielding dairy cows reduces metabolic and reproductive dysfunctions during early lactation. Cows (n= 202) were divided into two homogeneous groups regarding number of lactations and body condition score. 1) Treated group (GG; n= 112) received 60 g/cow/d for15 d of a glycogenic precursor during the transition period. 2) Control group (GC; n= 90) received no treatment. Postpartum levels of beta hydroxybutyrate (BHB) (GG= 0.9 ± 0.2 mmol/L vs GC =1.3 ± 0.2 mmol/L; P<0.05), and non-esterified fatty acids (NEFA) (GG= 0.6 ± 0.1 mEq/L vs GC = 0.8 ± 0.1 mEq/L; P<0.05) were higher in the GC-group. Similarly, GC-cows had a higher percentage of retained placenta (23 % vs 13 %; P≤0.06) subclinical ketosis (GG= 10 %, GC= 56 %; P<0.05), and mastitis (GG= 8 %, GC= 16 %; P<0.05). Metritis, dystocia, abortions, clinical ketosis, hypocalcemia and ruminal acidosis showed no differences between groups. Administration of a glycogenic precursor during the transition period demonstrated a positive effect upon BHB and NEFA blood levels during early lactation, with parallel decreases of subclinical ketosis and retained placenta; this could be an alternative to enhance the dairy herd reproductive efficiency.
