1. Beef Cattle Introduction and Breeds Advanced Animal Science Reeves

2. Characteristics of the Beef Industry n Segmented Industry 1. Cow/ Calf- commercial and purebred. They are the dictators of what's to come. 2. Stocker- graze phase 300-400#. Pays on gain (per lb). 3. Feedlot - Heavy weight cattle, confined operation 400-500# 4. Packer - “enemy,” Take feedlot cattle, grade them, sent out as boxed beef. 5. Purveyor- distributor 6. Retailer - HEB, Kroger, Randalls 7. Consumer- $5-6/ lb

3. Characteristics of the Beef Industry n Cow/ Calf - –Texas = 14.1 million (ranks #1, makes up 14% of the total US beef) –Kansas = 6.5 million –Nebraska = 6.5 million n Feedlot- 1. Texas 2.6 million 2. Kansas 2.2 million 3. Nebraska 2.2 million 4. Missouri 2.1 million

4. Breed Selection n 2 Main Factors –1. Genetics –2. Environment n Genetics –Determine advantages, disadvantages, then market ability. –Certified Angus Beef (50% Black, typical beef type, no floppy ear or hump larger than 4”, carcass avg choice or better, yield of 3 or better) n Environmental –Geographical environment, management env. And personal preference

5. Breed Selection n Production Criteria 1. Mature Size - will it fit the environment? Do not outgrow your environment. 2. Milk production - as milking ability increases, the nutritional requirements increase. (Ex. Simmental) 3. Muscle Amount - as we increase muscling, fertility rate decreases. (higher muscle results in distocia in males and females) 4. Sexual Maturity - age at puberty, when is the 1st ovulation 5. Management efficiency - easy keeper, foraging ability 6. Biological Specie- Bos Indicus vs. Bos Taurus

6. Bos Indicus vs. Bos Taurus n Bos Indicus –Humped Breeds Advantages –Heat resistant –resistant to parasites Disadvantages –less adaptable to cold –lower reproductive efficiency n Bos Taurus –Non Humped Breeds Advantages –Cold resistant –higher repro efficiency Disadvantages –heat tolerance low –susceptible to disease

7. Breed Selection n British/ English –Angus, Shorthorn, Red Angus, Hereford, Polled Hereford n European/ Continental –Simmental, Gelbvieh, Salers, Maine Anjou, Chianina, Pinzgauer n American –Brangus, Simbrah, Santa Gertrudis, Brahmousin, Beefmaster, Braford

8. Hybrid Vigor –The crossing of 2 totally different breeds. –We calculate it to give us an idea of heritability of traits (such as color, muscle, milk, reproduction) n F 1 have the most expression HV Calculating HV ww of offspring - Average ww of parents/ average ww of parents *100 = %HVWW ww= weaning weight (the weight at which an animal is taken off of the milk from mother)

9. Hybrid Vigor Example: Brahman Bull = 480 ww Hereford Cow = 500 ww F1 Calf = 525 480+500= 980 525- 490/490 * 100 = 7.14% 7%HV *If the ww of offspring is less than the best parent crossbreeding is useless.
