Mickey, Dana Marie (2021-07-19)The objectives of this study were to analyze calf performance traits and female reproductive traits in reciprocal F2 Nellore-Angus calves (n = 539) born 2010-2015 and calves out of these F2 females through 4 yr age (n = ...
-
Cunningham, Samantha Fern (2013-12-10)The overall objective of this study was to investigate various measures of cattle size. Records from three separate studies (herds) at Texas A&M University were used to evaluate relationships of birth and weaning measures ...
-
Holland, Paul Wesley (2018-07-24)Ewe reproductive life traits such as longevity and stayability (the probability that a ewe will avoid removal from the flock due to reproductive performance or health) are economically important because of the relationship ...
-
Woolfolk, Matthew (2014-08-18)The objectives of this study were to estimate heritability of performance traits in Brahman and Brahman-influenced (¼ or ½ Brahman) stocker cattle on cool-season (n = 1,732) and warm-season (n = 1,199) forages. Cattle were ...
-
Bauer, Lance William (2022-12-12)The goal of this study was to assess the correspondence between feed efficiency and maternal traits, feed efficiency and carcass traits, and carcass traits and maternal traits. Two sets of data from Beefmaster Breeders ...
-
Tolleson, Mallory Williams (2016-04-22)The objective of this study was to conduct a genome-wide association study for udder traits for crossbred cows. Average teat diameter, average teat length, and udder support score were evaluated in cows (n = 295) from 13 ...
-
Wilson, Kyle Everett (2021-04-14)The objective of the study was to evaluate genomic based inbreeding within a closed population of Nellore-Angus crossbred cows and the effect it has on growth and reproductive traits. From 2003 to 2018, cows were evaluated ...
-
Langdon, John Michael (2019-10-17)Sufficiently accounting for genotype-environment interactions would enhance genetic merit prediction and parameter estimation for traits of economic prominence in beef cattle. The objective of this work was to utilize ...
-
Bohac, Jennifer Kay (2015-12-01)Calf crop born, calf crop weaned, calf birth weight, calf weaning weight, and calf preweaning average daily gain (ADG) were evaluated from 1997 to 2009 in Brahman (B) and Angus (A) straightbred and crossbred cows (n = 194). ...

Holland, Paul W (2015-05-05)The genetics of coat color for cattle are important to breeders and breed associations because phenotypes of these animals are used for breed recognition and premiums or discounts can be given due to the phenotypes. The ...
-
Dillon, Jasmine Ashley (2013-12-04)Brahman cross calves exhibit unusual inheritance of birth weight: Brahman-sired crossbreds out of Bos taurus females are heavier with greater difference between sexes than calves of the reciprocal cross. The objective of ...
-
Hulsman, Lauren Lorene (2013-05-15)The objectives of this study were to 1) evaluate marker associations for genomic regions of interest and significant ontology terms, 2) evaluate and compare 4 models for their efficacy in predicting genetic merit, 3) ...

Delgadillo Liberona, Jose Sebastian (2019-07-10)Increase in world population constantly raises the global demand for food. To respond to this demand, livestock systems require to constantly increase their production and/or efficiency. Improvement of beef production can ...
-
Simmons, Matthew Aaron (2019-07-19)Diverse expression of any given trait within a breed is required to protect the breed from the unwanted consequences of selective breeding. Within the cattle industry, the fluid state of selective breeding trends, and ...
