The mixed model included cow age, season of measurement, and their interactions, year of birth, pregnancy-lactation code (PL), and breed-group as fixed effects for CW and CS. Analyses of weight adjusted for condition score included CS as covariate. The model for CH excluded PL. Random ...
This is just a sample of some of our cows, not all cows are on this page. Here is Kade’s cow, Meacham Betty 3002. She is another great cow by BK Danny Boy 908, who is a son of Danny Boy. Danny Boy calves come really light and show excellent growth. Th
The objective of the study was to assess variation in hair coat shedding of Angus cows, and its effect on adjusted weaning weight (d205wt) and BCS. Data were available from 532 Angus cows over 3years of age. Beginning in March and for 5months at 30-d intervals, trained technicians score...
Cow weight at weaning was adjusted to a constant BCS (5.0) and age (5.0 yr) prior to analysis. An increase in cow BW of 100 kg tended to increase calf weaning BW by 2.34 kg (P = 0.07). Additionally, for every 1 kg increase in calf birth weight, calf weaning BW increased by 2.07...
Fertility Index: Fertility selection index is an index that combines heifer pregnancy, stayability, the age a cow will first calve, mature cow weight, and back fat EPDs into a single number. The index is expressed as s standard deviation from the breed average, meaning that bulls with a +...
Annual THR fee-Sires: recorded bulls (excludes BB) 30 months of age or older. Includes recording of unlimited progeny conceived during assessed year.$25.00 First Calf Heifer: charged when the dam was too young to be assessed on THR for that cow year$25.00 ...
Perfect weight. With water: almost like pure barley syrup. Finish: medium length, perfectly balanced, ideally fruity, never vulgar—or let’s say ‘too much’. Comments: pure Longmorn, by and for Longmorn aficionados. Exceptionally high level for an 11-year-old. SGP:651 - 89 points....
cow-calfPreweaning data on 511 spring-born calves from 187 Brangus cows and 129 Bonsmara, Brangus, Charolais, Gelbvieh, Hereford, and Romosinuano sires were measured over a 4-yr period to determine sire breed, sex, and age of dam differences under 2 preweaning forage environments: 1) ...
The ability of Brahman crossbred dams to restrict calf birth weight is one of their most important attributes. Furthermore, these calves gained faster and had the heaviest weights at weaning. Reproductive performance is the most important trait in cow-calf production. Averaged over six years, calf...
