The objective of this research was to partition phenotypic variation in calf gain from birth to weaning, and milk production measured, by the weigh-suckle-weigh method, and udder score of cows into genetic and nongenetic components. Data were from the Line 1 Hereford population maintained by USDA-ARS at Miles City, MT, and included observations of pre-weaning gain (n = 6,835) from 2,172 dams, milk production (n = 692) from 403 cows, and udder score (n = 1,686) from 622 cows. Data were analyzed…

Genetic parameter estimations and genomic insights for teat and udder structure in young and mature Canadian Angus cows.

It is recommended that producers collect teat and udder score on their cow herd annually and that 12 genes overlapped for teat score in the two cow age groups, although there were no genes in common for the two Udder scores.


Udder quality is an important trait for beef producers because udders impact cow longevity and calf performance. The objective of this study was to estimate the genetic parameters for udder quality

Increase in the accuracy of selection for suckling performance in beef cows with a single-step, multiple-trait genomic evaluation model

The single-step and multi-trait genomic model paved the way for an efficient use of maternal EBV in beef cattle breeding programmes.

Direct and maternal breed additive and heterosis effects on growth traits of beef cattle raised in southern Brazil.

Heterosis effects were sufficiently large for use of N to be recommended as a component of such systems, despite their relatively low-breed additive effects compared with taurine breeds, and germplasm from the tropically adapted Bos taurus C may be particularly useful when increased milk production is desired.

Genetic parameters for calf mortality and correlated cow and calf traits in tropically adapted beef breeds managed in extensive Australian production systems

The genetic associations between cow teat and udder traits with maternal contributions to calf mortality were studied in Brahman (BRAH) and Tropical Composite cattle managed in extensive production systems of northern Australia, showing that larger calves at birth are less likely to die before weaning and have heavier weaning weights from maternal genetic contributions to these traits.

Milk yield and composition of primiparous recipient cows influence the performance and carcass ultrasonography of Nellore calf

Calves from Angus primiparous cows had greater body weight, average daily gain (ADG), longissimus muscle area (LMA) and longISSimus weight-to-width ratio than others, since those traits are associated with milk yield, and the Nellore cows delivered similar calves to the Angus cows, due to the better quality of their milk.

Insights into the genetic variation of maternal behavior and suckling performance of continental beef cows

The findings question the assumption that two populations that have close genetic links share many QTLs, and identify four candidate genes that may explain a substantial amount of the genetic variation in suckling performance of these two breeds.

Crossbreeding effects on growth and efficiency in beef cow–calf systems: evaluation of Angus, Caracu, Hereford and Nelore breed direct, maternal and heterosis effects

A cows matured most rapidly, weighed the least at maturity, produced the most milk, weaned the heaviest calves, were predicted to consume the least energy, and were therefore most efficient among the breeds that were evaluated.



Genetic parameters for milk production of Australian beef cows and weaning weight of their calves.

Results indicate that milk production is the main determinant of maternal effects on the growth of beef calves with breed differences in the importance of maternal results largely attributable to differences in milk production.

Genetic relationships among direct and maternal components of milk yield and maternal weaning gain in a multibreed beef herd.

A genetic correlation between CowWG and CowMY of .76 indicates that maternal weaning gain evaluations are a good predictor of a cow's potential for milk yield.

Effects of milk yield on biological efficiency and profit of beef production from birth to slaughter.

Milk yield was positively associated with gross margin from birth to slaughter (P < .05) and results were similar when cow feed prices were reduced by 30%.

Genetic and phenotypic parameters for type and production in Guernsey dairy cows.

The results suggest that selection for improvement of milk production will lead to correlated increases in dairy form, rear udder height, rear Udder width, andUdder depth and to correlated decreases in the strength of fore ud der attachment.

Relationship between milk expected progeny differences of polled Hereford sires and actual milk production of their crossbred daughters.

Extension of results of a single milking to an entire lactation is difficult, but over the range of sire milk EPD sampled (-10 to 16 kg), the range in daughters' milk production predicted from the regression analysis was 27% of the mean actual milk production, corresponding to an increase of about 1% more milk per kilogram of milk E PD.

Interrelationships of heifer milk production and other biological traits with production efficiency to weaning.

Results indicated that increased levels of milk production of heifers were associated with improved production efficiency to weaning, however, the incremental improvement in efficiency per unit of increased milk was less for each additional unit of milk, within the range evaluated.

Selection for postweaning growth in inbred Hereford cattle: the Fort Keogh, Montana line 1 example.

Demographic characteristics and genetic trends in birth weight and pre- and postweaning ADG were examined in a population of Hereford cattle (Line 1). Line 1 was founded largely from two paternal

Productive longevity of first-cross cows produced in a five-breed diallel: I. Reasons for removal.

Angus and Angus-cross cows were culled more frequently for structural unsoundness; Hereford cows had a higher incidence of cancer eye, calving difficulty and mammary problems; cows with 100% dairy breeding had exceptionally high susceptibility to diseases and mineral imbalance.

Evaluating longevity of composite beef females using survival analysis techniques.

Traits measured before 1 yr of age were not useful in predicting the subsequent longevity of cows and relatively low heritability and the lack of indicators of longevity expressed early in life suggest that genetic improvement of longevity will be difficult.
