“…Likewise, the ultrasonographic appearance of the reticulum does not change during and after eating hay and grass silage but the frequency of contractions and the interval between contractions changes significantly. 6,8 During feeding, the mean number of contractions of 10 calves during a 9-min measuring period was 18.5, which was a significant increase from 11.1 before and 11.5 after feeding. Because of the increased rate of contractions, the interval between contractions was significantly shorter (P < 0.01) during eating (21.7 sec) than before (41.1 sec) and after eating (37.3 sec).…”

“…The ultrasonographic appearance of the rumen does not change in pre-weaned calves during and after the ingestion of milk 7 and in ruminating calves during and after eating hay and grass silage. 8 The rumen is visible only from the left side on day 1 but from both sides thereafter. The longitudinal groove appears on the left as a mucosal fold, separating the dorsal and ventral sacs of the rumen, but the actual groove develops later ( Fig.…”

“…12 The mean duration of the first and second contraction was 2.5 and 3.9 sec in calves, which were similar to the values of 2.8 and 4.2 sec measured in resting cows 12 and 2.4 and 4.9 sec in pre-weaned calves. 6,7 Ruminating calves, pre-weaned calves and cows differed with respect to the speed Formatiert: Schriftfarbe: Hellblau, Durchgestrichen Formatiert: Schriftfarbe: Hellblau, Durchgestrichen of the first reticular contraction; it was 7.0 cm/sec in cows, 8 3.5 cm/sec in ruminating calves and 1.7 cm/sec in pre-weaned calves. 6,7 The approximately 4-fold increase from pre-weaned to ruminating calves to mature cows is an impressive illustration of the gradual reticular development in growing cattle.…”

“…The ultrasonographic appearance of the omasum remains unchanged in suckling calves during the ingestion of milk 7 and also in ruminating calves when they eat hay and grass silage. 8 The dorsal visible border of the omasum has a caudodorsal course (Fig. 8).…”

This article describes the ultrasonographic findings of the reticulum, rumen, omasum, abomasum, and liver of calves from birth to 100 days of age. Reticular motility is used to exemplify how the forestomach function in calves progresses and gradually approaches that of adult cattle. The ultrasonographic examination of the esophageal groove reflex and the investigation of factors affecting esophageal groove closure are described. The ultrasonographic findings of the forestomachs and abomasum of calves with ruminal drinker syndrome are discussed. The article concludes with the description of the ultrasonographic examination of the liver.

“…The reticulum, rumen, omasum and abomasum were examined ultrasonographically as 100 described previously in detail (Gautschi, 2010;Braun et al, 2012;Krüger, 2012). The calves were 101 examined six times at three-week intervals (Table 1) and 3.0 to 5.5 hours after being fed cow's milk 102 at a rate of 12 % of body weight.…”

The goal of this study was to examine the development of the reticulum, rumen, omasum and abomasum in six calves from birth to 100days of age by means of six serial ultrasonographic examinations. The examinations were carried out in standing animals using a 5MHz-transducer as described previously. The calves were primarily fed milk until examination 4 and then they were weaned. The reticulum was assessed for its shape and contractility, the rumen for its size and content, the omasum for its size, content and motility and the abomasum for its size and content before and after the ingestion of milk. The reticulum was seen in all calves starting at examination 2 and had biphasic and triphasic contractions; the latter were associated with eructation. The rumen was always imaged in all calves as early as Day 1 and its visible size increased progressively in all intercostal spaces (ICSs) during the study period. The omasum was best imaged in the 8th or 9th ICS; it was seen medial to the liver dorsally and usually medial to small intestines ventrally. Its visible size in these two ICSs increased progressively but omasal motility was not apparent. In newborn calves the abomasum was the largest compartment and dominated the abdominal cavity. It was visible from the 5th ICS to the flank. Except for examination 2, the mean visible abomasal length was significantly larger after feeding than before. Lateral abomasal extension to the left was greater than to the right at examinations 1-4, but was much smaller than to the right at examinations 5 and 6 because of progressive expansion of the rumen. Abomasal extension into the right hemiabdomen changed little during the study period. The goal of this study was to examine the development of the reticulum, rumen, omasum and 26 abomasum in six calves from birth to 100 days of age by means of six serial ultrasonographic 27 examinations. The examinations were carried out in standing animals using a 5 MHz-transducer as 28 described previously. The calves were primarily fed milk until examination 4 and then they were 29 weaned. The reticulum was assessed for its shape and contractility, the rumen for its size and content, 30 the omasum for its size, content and motility and the abomasum for its size and content before and
