4-H Livestock Judging: Activity 2, Different Strokes1

Chad Carr, Justin Crosswhite, and Amanda Johnson2

Activity 2. 

OBJECTIVES:

 

For youth to:

distinguish between breeds within a species.

 

identify sex characteristics within a species.

LIFE SKILLS:

Acquiring, analyzing and using information.

 

Communicating and relating to others.

MATERIALS:

Copy of BREED IDENTIFICATION CARDS

 

Copy of BREED CHARACTERISTICS CARDS

 

Copies of FULL OF CHARACTER crossword puzzle for each youth

TIME:

1½ Hours

SETTING:

A comfortable room with tables and chairs.

ADVANCE PREPARATION:

Cut out BREED IDENTIFICATION and BREED CHARACTERISTICS CARDS. Write to breed associations requesting pictures of the breed. Pictures of the common breeds will help the youth to recognize breed characteristics.

Different Strokes

Background Basics...

A breed is defined as a group of animals with a common origin which are distinguished by characteristics within a species. Breed character is defined as the characteristics that allow the breed of the individual animal to be easily determined. Different purebred breeds have different genetic strengths and weaknesses.

The offspring or progeny of different purebred breeds result in an animal that has genetic advantages compared to its parents. This is called hybrid vigor or heterosis.

Hog Breeds

The eight purebred breeds of hogs most utilized in the United States are the Landrace, Yorkshire, Duroc, Hampshire, Berkshire, Chester White, Poland China and Spotted breeds.

Generally, the three white breeds—Yorkshire, Landrace, and Chester White— excel at mothering or maternal traits, compared with the remaining breeds which have primarily been selected for growth, carcass merit, or terminal traits.

More information on the eight major purebred hog breeds can be found at http://www.ansi.okstate.edu/breeds/swine/

Cattle Breeds

Numerous cattle breeds give influence to the U.S. beef industry. Cattle breeds actually represent animals from two different species, Bos taurus and Bos Indicus.

The Bos Taurus breeds can be categorized into three groups: Dairy, British, and Continental. The Bos Indicus breeds used within the U.S. are categorized as American breeds. More information on these and other breeds can be found at http://www.ansi.okstate.edu/breeds/cattle/.

The Dairy breeds—Ayrshire, Brown Swiss, Guernsey, Holstein, Jersey, and Milking Shorthorn—are primarily utilized for milk production, but castrated bull calves certainly contribute to the beef industry.

The British breeds—Angus, Red Angus, Hereford, and Shorthorn—excel at reproductive efficiency, and marbling deposition or the amount of taste fat within the muscle tissue.

The Continental breeds—Charolais, Chianina, Gelbvieh, Limousin, Maine-Anjou, Salers, and Simmental—generally possess a large mature size, rapid growth rate, and heavy muscling. Each breed displayed distinct color patterns when imported into the U.S., however, the Charolais is now the only Continental breed which does not have black –hided animals.

American breeds—American Brahman, Braford, Brangus, Beefmaster, Red Brangus, and Santa Gertrudis—are all Bos indicus breeds of beef cattle developed in the United States. These cattle are known for heat tolerance and resistance to parasite populations. Most of these breeds are a result of crossing two or more breeds.

Sheep Breeds

There are more breeds of sheep than any other meat-animal species. More information on sheep breeds can be found at http://www.ansi.okstate.edu/breeds/sheep/. Sheep breeds can primarily be categorized into three groups: hair, wool, and meat breeds.

The two primary hair breeds—Dorper and Katahdin—are both easy care breeds which do not require shearing, primarily having hair rather than wool. The Merino, Rambouillet, and Columbia breeds are wool breeds specifically described as finewools which generate a high quality fleece which has a greater processing value for garments. The Lincoln and Cotswald breeds are also wool breeds known as longwool breeds which have a longer fleece. The primary meat breeds used in the U.S. are the Dorset, Hampshire, Montadale, Oxford, Southdown, and Suffolk. These breeds are much faster growing and have greater carcass merit than the wool breeds. The fleece quality is much poorer compared with the wool breeds. These breeds are often referred to as medium-wool breeds.

The table below shows the correct gender terminology within each of the species. These terms will often be combined to give even more information about a specific animal (e.g. heifer calf, wether lamb).

Introduction

Like humans, all animals have a genetic make-up. In livestock, it is easy to categorize groups based on their breed and sex characteristics. It is important for you to be able to distinguish among the types, breeds, and sexes. Ideal types and desirable characteristics vary widely among the sexes, breeds and use of the animal. Industry demands have the greatest impact on the desirable types within a breed or sex category and these will be discussed further in Activity 3. Today we will explore the different breed and sex characteristics within each species and learn to identify some of the more prominent traits of each. You will also get to know each other and learn to work together as a team through the "What Am I?" game.

DO Play What Am I?

  • Divide youth into two groups

  • Give each youth in the first group one BREED IDENTIFICATION Card. The youth in the second group each get one BREED CHARACTERISTICS clue card.

  • Have the youth circulate around the room finding the match to their breed characteristics clue or their breed card. This can be done by asking yes/no questions, by process of elimination and by the members helping each other find the person with their matching card.

  • Have youth sit down when they find their matches.

  • After everyone is seated, have each pair stand up and tell the group about the characteristics of their breed. If the information is incorrect, have youth continue their search.

  • Be sure that all the breeds and characteristics are covered.

Reflect

  • Did you have difficulty finding your breed's characteristics or breed identification?

  • Which sheep breed has the greatest fleece quality?

Merino

  • List some similarities among the swine breeds.

Example: Poland China and Berkshire each are black with six white points.

  • How are American breeds of beef cattle different from the British or Continental breeds?

American breeds were all developed here in the US and are a hybrid cross of at least two breeds. These animals are more adapted to tropical environments than British or Continental breed cattle.

  • What is the purpose of crossing the breeds during reproduction?

This results in heterosis or hybrid vigor.

  • Does the proper development of sexual characteristics influence the animal's net worth? Why?

Yes. The improper development of necessary sexual characteristics could produce an animal who is infertile or has other reproductive malfunctions and is of very little use to the producer. Development of desirable sexual characteristics could influence whether the animal gets chosen for reproductive or slaughter purposes, therefore having an influence on the animal's net worth.

  • Did you make any friends or meet someone new?

Apply

  • Visit an exhibit of animals (fair, youth show...) or a local ranch or farm. Discuss the characteristics and positive/negative attributes of each breed that you encounter, as well as identify the animal's sex.

  • Complete the FULL OF CHARACTER Crossword puzzle.
