After 40 minutes of feeding, the salivary secretion volume is low and the boluses collected via the esophageal fistula were dry and easily crumbled.
In the NFC control, the esophageal fistulae were always closed by the esophageal fistula plugs and the animals ate dry forage in the normal manner but were deprived of water during feeding.
On the experimental days, before starting the FBR treatment of experiment 2, the plug for closing the esophageal fistula was removed and an esophageal cannula for collecting boluses was fitted into the fistula (Figure 2B).
Figure 1A shows the esophageal fistula after complete recovery from the surgery.
The weight of warm water that was infused into the balloon in the rumen in the RIHS-IB treatment was equivalent to the weight of feed boluses removed via an esophageal fistula during the 2 h feeding period (Thang et al.
Before starting the SFC control of experiment 1, and both the RIAPS-NB control and the RIHS-IB treatment of experiment 2 in the present study on experimental days, the plug for closing the esophageal fistula was removed and a cannula for collecting boluses was fitted into the fistula.
The weight of water that was infused into the balloon in the rumen in experiment 2 was equivalent to the weight of feed boluses removed via an esophageal fistula during the 2 h feeding period.
Before starting experiment 1 (in both the NIB control and the RIB treatment) and experiment 2 (in both the RRIAS-NIB control and the RRIAS-RIB treatment), the plug for closing the esophageal fistula was removed and a cannula for collecting boluses was fitted into the fistula.
In the SFC treatment, the ingested feed left the digestive tract via an esophageal fistula before any gastric, intestinal or metabolic effects occurred.
The bolus output from the esophageal fistula (g) was measured during the 2 h of feeding (11:00 to 13:00 h) by using a feed box attached to a 12 kg measuring scale which was used to determine the weight of the bolus output from the esophageal fistula every 10 min.
