Growth patterns from birth to maturity were compared for 92 straightbred Herefords (H) and 299 Hereford crossbred (XB) cows. Crossbred cows were out of Hereford dams and were sired by bulls of two British [Angus (A) and Shorthorn (Sh)], two Continental [Charolais (C) and Simmental (S)] and two American dairy breeds [Brown Swiss (B) and Holstein (F)]. British XB and H cows differed only slightly...

The reliability of genomic breeding values (DGV) decays over generations. To keep the DGV reliability at a constant level, the reference population (RP) has to be continuously updated with animals from new generations. Updating RP may be challenging due to economic reasons, especially for novel traits involving expensive phenotyping. Therefore, the goal of this study was to investigate a minima...

were passing meat inspection. Meat inspectors were requested to submit lymph nodes that appeared abnormal as to size, color, or consistency. A total of 2843 dairy animals3 and 6791 beef animals was inspected on collection days. Lymph nodes were submitted from 736 cattle. Four dairy cattle were found to have malignant lymphoma following the histopathologic study. Two of these cows with extensive...

India is a subtropical country, wherein the climate is of variable type. A shelter is required both in summer as well as in winter to counter the various vagaries of adverse climate and to provide a comfortable environment to the animals. The principle functions of any system of housing for dairy cattle are: (1) Provision of health sustaining and comfortable environment to different categories ...

Longevity of productive life in dairy cattle is a characteristic difficult to evaluate. This measurement is complicated, in part, because the phenotype is expressed late in the life of the animal, but also because the methods of evaluation are complex. The molecular bases of longevity are still far from being fully understood, although some genes begin to be associated with this characteristic....

Hay and pasture crops are critical to Kentucky Agriculture and to that of the entire temperate region of the US. The sale of cattle, calves and dairy products provide 29% of Kentucky's farm income compared with 23% for tobacco. Beef cowcalf enterprises comprise the majority of cattle numbers in the state, however, dairy production is also significant. A substantial horse industry also exists in...

Brucellosis is a bacterial disease caused by brucella; mainly spread by direct contact transmission through the brucella carriers, or indirect contact transmission by the environment containing large quantities of bacteria discharged by the infected individuals. At the beginning of 21st century, the epidemic among dairy cows in Zhejiang province, began to come back and has become a localized pr...

A total of 45 lactating Holstein cows averaging 617 kg of BW were allotted at wk 20 of lactation to 9 groups of 5 cows blocked for similar DIM to determine the effects of feeding different concentrations of flax hulls (FH) on DMI, milk production, milk composition, and digestion. Cows within each block were assigned to one of the 5 isoenergetic TMR containing 0, 5, 10, 15 or 20% FH. The experim...

The Fleckvieh breed, while internationally recognized as a dual-purpose breed is primarily used as a beef production animal in Ireland. However because of ever increasing pressure to improve efficiency, it is now accepted in Irish cattle breeding that beef production characteristics should be included in the national dairy cattle breeding programme. This development was accepted following a com...

Farms that purchase replacement breeding cattle are at increased risk of introducing many economically important diseases. The objectives of this analysis were to determine whether the total number of replacement breeding cattle purchased by individual farms could be reduced by improving herd performance and to quantify the effects of such reductions on the industry-level transmission dynamics ...
