Sheep B-ultrasound machines can be used as a pregnancy detection tool to improve reproductive management of small ruminants in various production scenarios, from extensive production systems emphasizing wool production to intensive production systems utilizing multi production genetics, with a focus on meat production, to small ruminants. Ultrasound scanning has been proven to be a low-cost and accurate method for determining pregnancy status, pregnancy stage, and litter size. By grouping animals based on their pregnancy status, stage, and/or litter size, managers can improve productivity, allocate farm resources, and enhance the health and welfare of their flocks/herds.

Case study of sheep using B-ultrasound pregnancy tester

Pregnancy detection using B-ultrasound machine for sheep can better allocate feed resources. Separate ewes or remove non pregnant animals based on their pregnancy status, and then slaughter them or reduce feeding due to lower demand. In some production systems, failure to extract non pregnant animals from the pregnant group can lead to obesity. This not only wastes feed resources, but the implicit cost may also be that these animals cannot reproduce when re exposed, or if they become pregnant, there is a greater risk of ketosis. In productive chicken/cattle flocks, grouping based on the number of fetuses can better allocate feed resources, especially in the later stages of pregnancy, when nutritional requirements will change most significantly and dramatically according to litter size. Carrying single feed can reduce the burden and redistribute more and higher quality feed resources to breeders with multiple feeding ratios. This will lead to better pregnancy outcomes for the entire flock/herd. Compared to sheep with a lambing rate of less than 120%, fetal counting has the greatest utility in productive sheep/herds.

The results of sheep ultrasound machine detection provide refined feeding to meet the animal's needs during pregnancy. In an intensive production system that utilizes precise feeding management, animals can be fed accurately based on their pregnancy stage and litter size. Using this information to group animals and feeding them accordingly will reduce the incidence of metabolic diseases and optimize maternal and fetal nutrition.

Ultrasound detection can optimize the management of herd fertility. In intensive and extensive production systems, grouping based on the number of fetuses and pregnancy stage provides an opportunity to improve labor efficiency during birth. By separating ewes/ewes that may have a greater demand for childbirth at birth (ewes with multiple births are more prone to difficult labor and miscarriage problems) from those with fewer ewes (those carrying single ewes), resources can be appropriately allocated (labor, favorable windbreak delivery enclosures, warmer housing facilities) to achieve optimal delivery outcomes.

The ultrasound test results determine when to dry lactating animals during milk production in the milking parlor. The decision to dry lactating animals during milk production in the milking parlor can be made based on an understanding of their pregnancy status and stage. This allows for optimal drying period length in animal management to achieve better lactation performance and herd/flock health.

Ultrasound detection can detect pregnant ewes as early as possible. Early detection of pregnancy allows for the sale of non pregnant animals while they are still at high market value (under 12 months). The ability to reproduce before the age of one can be used as a selection tool to improve lifetime productivity, as it has been proven that lambs aged 12-15 months have higher lifetime productivity than ewes without it.
