The Basics of Pregnancy Toxemia (Ketosis)

The Basics of Pregnancy Toxemia (Ketosis)

This article was written by Kristy Blankers and Dr. Lisa Sharko. Introduction Pregnancy toxemia, also known as ketosis, is a metabolic disease in dairy goats that occurs during late pregnancy and is caused by an elevation in ketone bodies. Pregnancy toxemia most commonly develops one to three weeks before kidding. Late gestation is a period of high energy demand as the animal supports multiple fast-growing fetuses. If these energy demands exceed the goat’s intake, they enter a state of negative energy balance. Fat is mobilized from the doe’s fat stores and transported to the liver to be used as an energy source. The fat is broken down into ketones, which can be used as an alternative emergency energy source. However,…

Colostrum Quality Impacts on Kid Viability

This article was written by Marlene Paibomesai and originally published in the August 2018 issue of the Dairy Goat Digest. What is colostrum? Colostrum is the first secretion from an udder after birth. Colostrum is rich in nutrients and immune factors, such as immunoglobulins and immune cells that are important for immune and digestive system development (Sanchez-Macias et al., 2014). Colostrum is higher in protein, fat, growth hormones and immune factors than milk. Why do newborns need colostrum? Unlike other mammals, ruminants transfer limited amounts of immunoglobulins and other immune factors from the dam to the fetus during pregnancy. Instead, the majority of immune factors are transferred through colostrum to the goat kid after birth. This is called passive immunity.…

Extended Lactation- What the Research Says

This article was written by Kristy Blankers and Delma Kennedy. Introduction After a normal lactation (NL), extended lactation (EL) goats start a second lactation curve during the production period at about 330 days when milk yield begins to increase again. Figure 1 compares the lactation curves of goats in normal and extended lactations over a two-year period. Figure 1; Lactation curves in goats in extended lactation compared to the lactation curves of goats in two subsequent normal lactations (Douhard et al., 2013). Differences between the normal and extended lactation curves include: Weight Change Goats maintain their weight when they aren’t bred and start to gain weight after 330 days when milk yield begins to rise as shown in figure 2.…

Pregnancy Scanning: Management Tips

Pregnancy Scanning: Management Tips

This blog post was adapted from the OMAFRA Factsheet “Pregnancy Scanning: Management Tips” (AGDEX 433/22) by A. O’Brien. Introduction Pregnancy scanning, using real-time ultrasound equipment, is a useful management tool for Ontario sheep and goat producers. When scanning is performed within the recommended time frame by trained professionals, accuracy of identifying animals that are not pregnant and counting the number of fetuses is high. Pregnancy scanning can be used to assign open ewes to new breeding groups, make culling decisions, and optimize feeding management based on expected litter size. Benefits of Ultrasound Scanning Identify and manage open (not pregnant) ewes or does. Count fetuses to improve feeding management. Improve newborn survival through appropriate feeding management. Determine appropriate dry-off time in…

Bonding Pens for a Doe and Her Kids

Bonding Pens for a Doe and Her Kids

In preparation for kidding, setting up bonding pens (also referred to as claiming pens or kidding pens) a few weeks in advance is often a good idea so when does start to kid you are prepared and can focus on kidding and daily chores, instead of building pens. Claiming pens assist the doe in establishing a strong maternal bond with her kid(s).
