Twelve hours after observed heat, transrectal ultrasound of follicular dynamics was initiated. Thereafter, ultrasound evaluation was repeated after 6 h, then every 3 h until ovulation confirmed loss of the dominant follicle. Growing preovulatory follicle dimensions were recorded at each time point. Blood samples were collected (Corvac, Covidien, IA) every 6 h for serum E2-concentration analysis.
SSD-500V
The SSD-500V is a diagnostic ultrasound system manufactured by Aloka. It is designed for general diagnostic applications. The system features a high-resolution display and advanced imaging capabilities.

Equine Body Composition Ultrasound Evaluation
Sow Feeding and Piglet Performance
was determined as the difference between the allowance and leftover feed
collected the next morning. The back-fat thickness was measured ultrasonically
(SSD-500V, Aloka, Wallingford, CT, USA) on each sow before farrowing and at
weaning at the last rib and 65 mm from the dorsal midline [20 (link),21 (link)]. The weights
of suckling piglets were measured on day 1 and 21. A veterinarian monitored the
deaths of piglets by crushing and disease through daily inspections, and the
number of crushed piglets was recorded every day. Estrus checks for all sows
were conducted twice daily using intact boars from 3 days after weaning until
the end of estrus. The occurrence of estrus was defined by the standing reflex
in front of a boar and the reddening and swelling of the vulva. Litter weight
and litter size were recorded on the day of birth after cross-fostering and on
the day of weaning.
Sow and Litter Performance Monitoring
based on the difference between the feed allowance and leftover food.
The back fat thickness of each sow was measured ultrasonically (Aloka SSD-500V,
USA) before farrowing and at weaning stage at the level of the last rib and 65
mm from the dorsal midline [19 (link),20 (link)].
The number of crushed piglets was recorded every day, and estrus detection was
carried out every 12 h after 3 days of weaning until the end of estrus.
Occurrence of estrus was defined according to the standing reflex in front of a
boar and through the reddening and swelling of vulva.
Litter weight and litter size were recorded on the day of birth (d 0) after
cross-fostering, and on day 21 (weaning).

Grazing System Effects on Horse Health
Horse BW, BCS, and percent body fat (FAT) were measured monthly to determine the effect of grazing system on horse health. Horse BW was measured using an IND221 electronic scale (Mettler Toledo, Columbus, OH), and BCS was assessed on a scale of 1 to 9 (Henneke et al., 1983 (link)). Horse FAT was determined by ultrasound (Aloka SSD-500V with linear 3.5 mHz probe, Tokyo, Japan) of subcutaneous rump fat thickness (Westervelt et al., 1976 (link)). Fat thickness was measured on both sides of the rump, and the average was entered into a regression equation to determine overall body fat percentage (Westervelt et al., 1976 (link)).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
