| [Image: Beef Cattle Shrink]Beef Cattle Shrink Many producers do not understand that shrink is a weak link in marketing cattle. Cattle producers spend a great deal of time and energy to make their cattle gain weight and weigh as much as possible. Then, when they pen, process and transport their cattle for market, the cattle lose weight. An increase in knowledge about shrink and the factors that affect it is critical to maximizing profits. |
| [Image: Effects of Subclinical Infections of Internal Parasites on the Production of Beef Heifers]Effects of Subclinical Infections of Internal Parasites on the Production of Beef Heifers Beef cattle in Louisiana are continuously exposed to infections with parasitic gastrointestinal nematodes (commonly known as roundworms). The life cycle of these parasites is direct; they do not need an intermediate host. Adult worms in cattle shed eggs that are passed in their feces. These eggs hatch and develop into infective larvae that climb on growing forage and are ingested as the forage is consumed. These larvae develop into adults and the cycle is completed within 14 to 60 days. |
| [Image: cover of research results of tropical adapted beef cattle breeds]A Compilation of Research Results Involving Tropically Adapted Beef Cattle Breeds The southern United States contains almost half of the nation's cow-calf population in the hot/humid Southeast and Gulf Coast areas.

| [Image: Document image]Supplementation of Mature Crossbred Cows Fed Bermudagrass Hay During the Last One-third of Gestation These data suggest that good quality hay fed free choice can meet nutrient requirements during the last one-third of gestation, a period when the nutrient requirements of the cow increase because of the growth of the fetus. |
| Rotational Crossbreeding of Beef Cattle: Weaning Weight per Cow Exposed and Cumulative Weaning Weight per Cow in Breeding Herd The purpose of this report is to compare the performance of two-, three- and four-breed rotational crossbreeding systems and straight-breeds for calf weaning weight per cow exposed and for cumulative weaning weight per cow entering the herd. |
| Value of Gain Spreadsheet Decision Tool This spreadsheet decision tool is updated on a monthly basis with Louisiana cattle prices. It allows producers to see the historical additional revenues by adding weight to cattle over a several-month period. No assumptions about costs of production are made; simply, the historical additional revenues are shown. Historical prices by class of cattle and corresponding seasonal indices are included. |
| Costs to Develop Replacements Heifers This spreadsheet is designed to assist cow/calf producers with determining the costs associated with developing replacement heifers. The cost associated with developing replacements heifers from one's own herd can then be compared to the costs associated with purchasing replacement females in the open market. A comparison of the expected returns from each strategy is included to help producers understand which alternative may work best for their individual operation. |

| Impact of Moderate and High Weaning Weight EPD Sires on Cow Productivity Expected progeny differences for growth traits are well documented and used by a large segment of the beef cattle industry. Calf weaning weight is greatly influenced by genetic potential for growth, therefore verification of how reliable weaning weight EPDs are on commercial cow herds needs to be studied. |
| Does Ryegrass Variety Matter in a Beef Stocker Program? Research conducted by the LSU AgCenter in the 1980s clearly revealed a profit potential for stocker beef production in Louisiana. Annual ryegrass has the productivity during the cooler parts of the year (late-fall, winter, and spring) and the nutritional quality necessary for growing beef animals to play a major role in most Louisiana beef stocker programs. |

| Evaluation of Angus-, Brangus-, Gelbvieh-, Gelbray-sired and F1 Brahman x Hereford Females for Cow-Calf Production The objective of this study was to compare three-breed cross females (Angus-, Brangus-,Gelbvieh- and Gelbray-sired) with contemporary first cross (F1) Brahman x Hereford females for reproductive and maternal performance. |
| Bayou Beef Tips: Winter Feeding of Beef Cattle During the winter, even on the Gulf Coast, beef cattle must have supplemental forage and/or feed. Most cattle producers in the South spend approximately 40% of their operating costs on producing or purchasing hay and purchasing supplemental feeds. |
| Estrus Synchronization Using MGA or Altrenogest in Crossbred Beef Heifers Estrus synchronization had its humble beginnings in the 1940s when progesterone and pregnant mare serum gonadotropin were administered to cattle at varying stages of the estrous cycle to alter cyclicity. The objective of this study was to evaluate the effectiveness of altrenogest for estrus synchronization of crossbred beef heifers. |
| Louisiana Cow/Calf Budget This spreadsheet-based, decision-making tool is based on the annual LSU AgCenter enterprise budgets for beef cattle. The spreadsheet allows producers to alter assumptions and print a projected budget based on their individual operations. |
| Calf Weaning Can Alter Nutrient Requirements of Cows Louisiana forages are often low in quality in late summer. Nutrient intake from forage by a mature cow will usually exceed the requirement for maintenance but may not be high enough to meet the additional requirement for lactation. When nutrient intake is below requirements, the cow must pull nutrients from body reserves to meet her requirements. The result is weight loss and a decrease in body condition. |
| Louisiana Seasonal Cattle Price Patterns Production agriculture is affected by seasonal production and demand cycles that are influenced by weather conditions as well as biological processes. These supply-and-demand conditions lead to seasonal price patterns. Awareness of seasonal price patterns can improve production and marketing decisions made by producers. (PDF Format Only) |
