4-H

Raising a beef project is a great way for youth to learn about livestock and raise a quality market product through the 4-H program. In this document we have listed some strategies and resources that will help ensure you have a successful project experience for your local fair and auction. Some essential considerations include ration composition, ration schedule, and understanding/planning around your beef’s ability to gain weight. Be sure to work with your county Extension staff and 4-H Leaders to find additional resources and have the best chance for success!

Raising a swine is a great way for youth to learn about livestock and raise a market product through 4-H. In this document we have listed some strategies and resources that are important in making show weights and growing a high-quality agricultural product. Some important things to know about your swine project include appropriate feeds and feeding, planning to ensure your swine makes weight for the show, and how to spot common health problems. Be sure to work with your county Extension staff and 4-H Leaders to find additional resources and have the best chance for success!

• Average Daily Gain: Average Daily Gain = weight gain since last weighing divided by number of days since last weighing.
• Basic dietary nutrients: Livestock nutrition requires 5 key elements - water, crude protein, carbohydrates, minerals, and vitamins.
• Beginning weight calculation: To calculate the ideal beginning weight for your livestock project, subtract the pounds of gain needed before fair from the desired weight at fair. Written another way: Beginning Weight = (desired weight)-(pound of gain needed before fair)
• Biosecurity: Refers to the planning and implementation of measures that maintain healthy environments for livestock and prevent the spread of infectious disease. 4-H members participating in a livestock project should make a biosecurity plan specific to their livestock facilities.
• Carbohydrates: High energy feeds that are higher in starches. Main source of energy for animals.
• Concentrates: Refers to feeds that are rich in energy (carbohydrates) and/or protein but low in fiber.
• Conversion rate: The ratio of pounds of feed given to the animal to pounds of weight gained. This rate is sometimes written as “feed to gain” or shortened to F:G. 4-H members should pay careful attention to the conversion rate of their particular animal by weighing their feed and calculating ADG in comparison to daily ration weights.
• Crude Fiber: Carbohydrates that are identified as indigestible. When crude fiber content is higher, the energy content of the feed is lower.
• Crude Protein: Composed of both true protein and nonprotein nitrogen (NPN). Many NPN compounds can supply nitrogen to the rumen microbes that then build microbial protein in the rumen. Proper crude protein levels are important for your livestock project as they are essential for animal growth and muscle development. 
• Daily weight gain needed before sale calculation: To determine daily gain requirements before fair use the following calculation:Daily Gain Needed = (target sale weight-current animal weight)/(days until fair) 
• Dietary energy: Refers to the amount of carbohydrates included in a ration. Amounts of high energy feeds change over the lifespan of a livestock project and can significantly affect finish quality.
• Finishing ration: A diet for animals in the last stage of feeding and is designed to promote fat deposition. Finishing rations tend to be high in energy and lower in protein than a growing ration.
• Forages: Forage feeds include pasture feeding, hays, and silage. Forages generally are an excellent source of fiber, which is essential for keeping ruminants healthy, and legume forages such as alfalfa can serve as a quality protein source as well.
• Growing ration: A diet for animals to grow muscle rather than fat. Typically consists of a higher percentage of protein and moderate fiber and energy.
• Holding: Feeding to maintain weight, i.e. not gain or lose. This is a useful strategy when timing a pig’s weight to your show or auction.
• Lysine: An essential amino acid. It contributes to calcium retention, energy production, muscle and bone development, and other key factors in your livestock project’s development. Different amounts of lysine are required at different stages of an animal’s life cycle, for more specific guidance see the other livestock references linked in this document. 
• Minerals: Inorganic feed elements essential for life.
• Nutrients: An ingredient or substance that provides nourishment is needed for growth and energy. 
• Protein: A nutrient that animals need to grow and repair cells. It is needed to develop nearly all types of animal tissue and helps power key chemical reactions, such as muscle development and hemoglobin synthesis.
• Pushing: Feeding higher calorie feeds or larger rations to pigs that are not gaining weight. A useful strategy when trying to meet minimum weights for a show or adapting feeding strategies to a slow gaining animal.
• Quality Assurance: The knowledge and care of livestock implemented by producers to provides consumers with a safe and wholesome food product. This includes proper feeding, safe use of drugs, biosecurity, and other important topics. 4-Hers are required to complete a quality assurance program, such as Youth for the Quality Care of Animals, when participating in a livestock project. 
• Rate of Gain: Determines if your livestock is on track to reach your target weight before the date of sale, use the following calculation: (days until fair) x (Average Daily Gain). This will help you determine if feeding adjustments are required to maintain, push, or hold your animal’s weight.
• Rations: Refers to the feed allowance an animal has in 24 hours.
• Roughages: Bulky and coarse feed that is high in fiber (greater than 18 percent crude fiber), but lower in energy than most concentrates. Examples include forage, hay, and silage.
• Rumen: The largest stomach compartment of a ruminant animal. It consists of several sacs and acts as a storage area for feed. It also serves as the fermentation area, where microbes digest and ferment feed to make fatty acids. 
• Ruminants: A hoofed mammal that has a complex multi chambered stomach with digestion achieved primarily through fermentation. Includes cattle, sheep, and goats. These animals can better use energy from fibrous plants.
• Total Digestible Nutrients (TDN): Then energy value of feed. When growing, an animal's ration tends to be lower in TDN. When finishing animals feed tends to be higher in TDN.
• Total Mixed Ration (TMR): Mechanically mixed ration ingredients that meet nutrient needs of cattle.
• Vitamins: Organic compounds that are essential for many metabolic functions.
• Withdrawal Period: The time it takes for drugs and chemicals to be broken down and processed so there is no remaining residue.
• Youth for the Quality Care of Animals (YQCA): This is a quality assurance training that outlines proper care of livestock. Visit the YQCA website for more information.
