Informal Project Reports
Growth of loblolly pine (Pinus taeda L.) plantations in East Texas is influenced by many factors - soil, genetics , insects, diseases, associated vegetation and climate - to list a few items. Insights into the role that these factors contribute to the production of wood might assist East Texas plantation managers in establishing, growing and harvesting planted trees.
Genetic And Phenotypic (Co)Variances For Growth And Carcass Traits Of Purebred And Composite Populations Of Beef Cattle, K. E. Gregory, L. V. Cundiff, R. M. Koch
Genetic And Phenotypic (Co)Variances For Growth And Carcass Traits Of Purebred And Composite Populations Of Beef Cattle, K. E. Gregory, L. V. Cundiff, R. M. Koch
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Least squares means, genetic (σg), and phenotypic (σp) standard deviations, and phenotypic coefficients of variation (CV) were estimated on an age-constant basis for growth, carcass, and meat traits of castrate males from 12 breed groups combined, for 9 purebreds combined, and for the F3 generation of three composite populations combined to which the nine purebreds contributed. Also, heritabilities ( h2) and genetic ( rg) and phenotypic ( rp) correlations were estimated among growth, carcass, and meat traits for all breed groups combined involving 1,594 individuals that were the progeny of …
G95-1235 Growth Implants On Beef Heifer Reproduction, Gene H. Deutscher
G95-1235 Growth Implants On Beef Heifer Reproduction, Gene H. Deutscher
University of Nebraska-Lincoln Extension: Historical Materials
This guide discusses the benefits and concerns in the use of growth implants with beef heifers. Growth promoting implants are used extensively in beef cattle finishing programs and in suckling and growing steer programs. Implants are one of the most economical means of improving performance. However, producers are concerned with implanting suckling and growing heifers because of the possible negative effects on subsequent reproduction of heifers selected as replacements. Replacement heifers need to grow rapidly, reach puberty early, conceive early, and increase in skeletal structure to reduce calving difficulty. If implants could be used to increase growth and skeletal structure …
Growth Of Early Maturing Soybean, M. V. Kane, Colleen C. Steele, Larry J. Grabau
Growth Of Early Maturing Soybean, M. V. Kane, Colleen C. Steele, Larry J. Grabau
Agronomy Notes
Production of early maturing soybean varieties has grown in popularity across the southeastern US in recent years. Many growers in Mississippi, Arkansas, and Texas have seen this system as a way to avoid late season drought. However, several Kentucky growers have had good success with the use of Maturity Group (MG) II soybeans in the recent seasons which had generally good rainfall patterns. Some growers are glad to get competitive yields from MGII soybean while gaining the opportunity to harvest some of their soybean acreage before corn is ready to harvest.
