Breeding Season Considerations for Sheep and Goats

As fall season approaches, daylight begins to get shorter, and sheep/goats are ready for breeding. The breeding season should be an exciting time for producers because the number of lambs and kids raised and weaned successfully determines the profitability of the operation. Understanding the reproductive system of the animals helps to maximize the breeding season and use resources wisely. This is particularly true for beginning producers who are experiencing their first breeding season. The season of the year is the main determinant for sheep and goat reproduction, with the majority being seasonal breeders that cycle in the fall (their natural mating season) and lamb in the spring. However, some breeds will cycle in the spring and have lambs/kids in the fall.

Peak fertility is from late September through November. Ewes have an average cycle length of 17 days, with most being between 14 and 20 days, while does have an estrus cycle of 18 to 22 days, and they display estrus for 24 to 48 hours. The gestation period ranges between 144 and 152 days. Management practices for producers to ensure profitability during the breeding season are highlighted below.

How to Meet the Mineral Needs of Livestock in Mixed Pastures

Minerals are critically important for the health and well-being of livestock. Reproductive performance and growth are improved when animals consume proper amounts of minerals (and vitamins). Animals have specific requirements for these minerals and differ by species and level of production.

One problem many have is that cattle, sheep and goats are frequently pastured together. Since sheep are vulnerable to copper toxicity, a general livestock mineral mix without copper is usually fed to the group. But that leaves cattle and goats without proper copper in their diets. This article provides alternatives for supplementing different livestock.

Sheep options
Purchase or construct a small-area mineral feeding station that larger animals can’t access. One option is Continue reading How to Meet the Mineral Needs of Livestock in Mixed Pastures →

How to Sample Hay

With the recent drought Ohio and much of the United States has experienced this year to date, analyzing and understanding forage quality will be critical for operation success. Wether you are feeding a few sheep in your back yard or have 1,ooo ewes indoors, knowing what you are providing to your stock in your pastures or in the feed bunks is important. This week, Mindy Ward outlines key steps to follow when collecting a hay sample.

As hay condition comes into question, take a closer look at your harvested bales.

Plan Now to Make your Summer Forage Seeding!

Stan Smith, OSU Extension PA, Fairfield County

With Ohio’s wheat harvest being completed early this year it allows ample time to plan and prepare to do an August forage seeding. Over the next month soil fertility testing should be accomplished, perennial and biennial weeds can be controlled, and ample time remains for selecting and securing the desired forage species for seeding.

During the winter of 2021 the first session of the Ohio Beef Cattle Management School focused on making quality hay for beef cattle with an emphasis on soil fertility and seed species selection when doing a new seeding. The first video embedded below is the 38 minute presentation from that first Beef School session when Noble County Extension Educator Christine Gelley discussed considerations for selecting species for a new seeding and other critical considerations when establishing a new stand of forage. Beginning at about the 14 minute mark of the presentation Gelley spends a few minutes discussing the specifics of seed species selection for new seedings.

Also, posted in the second video below, Jason Hartschuh, OSU Extension Field Specialist for Dairy Management and Precision Livestock, discusses soil fertility practices that will prolong the life, quality and productivity of hay and forage stands.

Composting On-farm Mortalities

On-farm composting is an approved method to dispose of livestock mortalities. Advantages include increased biosecurity, timely disposal of mortalities, low risk of environmental contamination, low cost, and relatively simple to do. Composting can be used for occasional mortality, emergency livestock mass casualties, and disease outbreaks.

What is composting?
Composting is an aerobic (with oxygen) recycling process where microorganisms break down organic material in a controlled environment to produce a stable product called humus. There are many ways to compost livestock mortalities. However, there are a few basics that are universal to all systems. Well-managed composting provides aerobic (oxygen-loving) microorganisms with the proper environment to grow and rapidly break down the mortality.

What’s Wrong with Stacking Round Bales?

Moving round bales out of a field and under cover may seem like one more item on the to-do list of a busy hay season, but rushing to complete this step may result in improper storage that can squander the forage yield and quality farmers worked so hard to achieve.

In a recent article from the Midwest Forage Association’s Clippings newsletter, Sarah Bauder with South Dakota State University encourages best storage practices to conserve dry matter and quality in round bales. The forage field specialist suggests bale storage is just as important to product value as plant maturity, harvest management, and pest control.

Dry matter and quality losses occur when water is trapped in hay and causes spoilage. This can be exacerbated by several factors, including hay binding, storage structures, bale stacking, and time.

Densely made bales are Continue reading What’s Wrong with Stacking Round Bales? →

Sheep Water Requirements and Quality Testing

Water intake is critical in ensuring animal health, performance and mitigating heat stress. In general, sheep will drink 1.0 to 1.5 gallons of water for every 4 pounds of dry matter (DM) consumed. Sheep need access to fresh, clean water with adequate space to ensure proper intake. Unclean or poor-quality water can negatively affect consumption, subsequently decreasing productivity, health and growth.

Understanding Water Requirements
Water requirements for ewes are listed in Table 1. Actual water consumption will vary with changes in temperature and humidity. Additionally, water requirement changes with stage of production, as pregnant, lactating and ewes raising multiples have the greatest water requirements. It is generally recommended that ewes raising twins or more require double the amount of water to support fetal growth and lactation (NRC, 2007).

Water is considered the most-important nutrient, because of the vast number of biological functions that rely on water. Growth, development and reproduction may be inhibited by not providing enough fluid water to a flock. Continue reading Sheep Water Requirements and Quality Testing →

Ewe Flock Nutrition

Introduction
Nutritional management is one of the most important aspects of sheep production. Ewes that are fed appropriately are more fertile, milk better and wean more lambs that grow faster (Figure 1).

Not only do well-fed ewes wean more pounds of lamb per year, but they are healthier and more resistant to disease than ewes that are under nutritional stress. In fact, many production challenges for sheep producers are caused by inadequate nutrition, rather than disease.

Additionally, feed costs are the single largest expense on sheep farms in Ontario, accounting for approximately 41% of total expenses. The 2010 Ontario Sheep Enterprise Analysis Summary (26 producers, representing 10% of the provincial flock) reported average feed costs of $106.70 per lamb produced for the 10 least profitable flocks and $69.00 per lamb (35% less) for the 10 most profitable flocks.

Appropriate feed management can be the difference between a profit or a loss for each lamb sold. Therefore, it is imperative that producers evaluate the feed resources they have and manage them carefully to maintain good ewe nutrition and the profitability of the flock.
