(Texas A&M University. Libraries, 1977)A model was developed for simulating beef cattle production under a wide range of management achemes and environments with a wide range of cattle genotypes for size, growth, and milk production. Genotypes are specified as ...

(Texas A&M University. Libraries, 1969)Data from the Gulf Coast Beef Cattle Pasture Research Station, Angleton, Texas and records collected by the author at the Beef Cattle facilities, Texas A&M University, College Station, Texas were included in this study. ...
-
(Texas A&M University. Libraries, 1965)Data from Experimental Station herds in Alabama, Florida, Georgia, Louisiana, North Carolina, South Carolina and Texas were included in this cooperative Southern Regional Beef Cattle Breeding Project (S-10) study. Records ...
-
(Texas A&M University. Libraries, 1994)Inconsistencies across studies and analytical designs emphasize a problem inadequately addressed in most recent theoretical studies on QTL detection and MAS: that posed by the intrinsic non-additivity of genetic/biological ...

-
(Texas A&M University. Libraries, 1988)Individual feed consumption, slaughter, and carcass data were obtained on 197 bulls produced in a diallel involving Angus, Brahman, Hereford, Holstein and Jersey and slaughtered at either 6, 9, 12, 15, 18, 24 or 30 mo of ...
-
(Texas A&M University. Libraries, 1970)Five nonlinear regression models were compared on their respective fitting qualities and appropriateness for biological studies of the weight-age curves in cattle of beef and Jersey breeding. Model V, y[subscript t] = A(1 ...
-
(Texas A&M University. Libraries, 1987)Genetic parameters were estimated for three measures of racing capacity in Thoroughbreds; (1) mean seconds per furlong of the race (MSPF-Race); (2) mean seconds per furlong of the stretch (MSPF-Stretch), the portion of the ...
-
(Texas A&M University. Libraries, 1965)Weaning and yearling data from 604 Rambouillet, Targhee and Columbia ewes of the Montana Agricultural Experiment Station, Bozeman, Montana, were used to estimate genetic parameters of production traits of economic importance. ...
-
(Texas A&M University. Libraries, 1986)Birth, growth and carcass data on cattle raised at Riesel, Texas were analyzed to evaluate Zebu sire breed differences. Zebu breeds included Gray Brahman (B), Red Brahman (R), Gir (G), Indu-Brazil (I) and Nellore (N). Angus ...
-
(Texas A&M University. Libraries, 1987)Data from a purebred Rambouillet range flock between the years of 1919 and 1985 were analyzed to determine: the relationship of age, body weight, birth type, sex of natal twin on lamb and fleece production, and longevity; ...
-
(Texas A&M University. Libraries, 1969)Data for this study were obtained from milk collected from samples of five beef breeds and one dairy breed of cattle located at Livestock and Forage Research Center, McGregor, Texas; Beef Cattle Center and Dairy Cattle ...
-
(Texas A&M University. Libraries, 1968)Data for these analyses were taken from Dairy herds of the Department of Animal Industries, Tropical Center of the Inter-American Institute of Agricultural Sciences, Turrialba, Costa Rica. The maximum annual ranges in ...
-
(Texas A&M University. Libraries, 1965)Production and carcass data from 241 calves sired by 34 bulls of the Hereford, Brahman, Santa Gertrudis, Charolais, Charbray, and Brown Swiss breeds were analyzed to estimate phenotypic and genetic parameters for fourteen ...
-
(Texas A&M University. Libraries, 1993)The Texas A&M Beef Cattle Production model was expanded to include basic concepts of quantitative genetics. The traits simulated were birth weight, yearling weight, mature weight and milk production. In the original model ...
