Effects of rate and amount of propionic acid infused into the rumen on feeding behavior of Holstein cows in the postpartum period

Abstract

The objective of this study was to determine the effects of 2 amounts of propionic acid (PA) infused intraruminally at 2 rates of infusion at the initiation of meals on the feeding behavior of Holstein cows in the postpartum period. We hypothesized that the amount and length of time of infusions would interact to affect feeding behavior: rapid infusion of a higher dose of PA would result in larger meal size with greater time between meals compared with a slower rate, whereas faster infusion of a lower dose of PA would reduce meal size and the time between meals compared with a slower infusion of the same dose. Eight ruminally cannulated, multiparous Holstein cows were used in a 4 × 4 Latin square design experiment. Cows were blocked by parturition date and randomly assigned to treatment sequence within square. Treatments were infusion of 2.5 L of 0.5 M (HI) or 0.2 M (LO) solutions of PA at initiation of meals over 5 min (FST) or 15 min (SLW) for 12 h following feed delivery. Contrary to our hypothesis, no interaction between amount and rate of infusion was detected for any feeding behavior parameter measured. The FST treatments did not affect dry matter intake or metabolizable energy intake compared with SLW. The FST treatments tended to increase meal length compared with SLW (28.1 vs. 22.7) but did not affect meal size. The FST treatments tended to decrease total eating time (108 vs. 122 min/12 h) but did not affect meal frequency compared with SLW. The HI treatments decreased dry matter intake (7.4 vs. 11.5 kg/12 h) and total metabolizable energy intake (22.5 vs. 29.1 Mcal/12 h) compared with LO by decreasing meal frequency (5.8 vs. 7.5 meals/12 h). The HI treatments decreased eating time (103 vs. 127 min/12 h) compared with LO but did not affect meal size. Further research is warranted on the effects of the temporal supply of propionate on propionate metabolism and feeding behavior.

“…This interference could occur because of the ability of propionic acid to stimulate satiety in ruminants (Allen, 2020). However, the propionic acid concentrations observed in the inoculated DCS and SS were far below the concentrations proven to interfere with ingestive behaviour and animal nutrient intake (Grant & Ferraretto, 2018; Maldini & Allen, 2019).…”

“…Similarly, higher propionic acid concentrations in the inoculated DCS and SS could also interfere with feeding time and DM intake (Maldini & Allen, 2019). This interference could occur because of the ability of propionic acid to stimulate satiety in ruminants (Allen, 2020).…”

Effects of physical preparation of diets and inclusion rate of modified wet distillers grains with solubles on production and rumen measurements of lactating dairy cows

“…Decreased acetate concentration in the rumen by feeding MWDGS might indicate a limitation of precursors required for de novo synthesis of milk fatty acids. On the other hand, increased propionate would stimulate insulin, which would favor partitioning of milk fat precursors to adipose tissue, and might affect feeding behavior or DMI (Maldini and Allen, 2019). These effects also could contribute to decreased milk fat synthesis.…”
