Which breed of cattle has more production than a two-breed cross?

Three breed crosses yield more production than a two-breed cross or back cross. Also, heterosis is slightly greater between Hereford-Angus crosses and Hereford-Shorthorn crosses than Angus-Shorthorn crosses. This suggests a greater similarity in genetic makeup between Angus and Shorthorn cattle than either with Hereford.

How much more calf can you wean from a crossbred cow?

When the responses to crossbreeding are accumulated, 15 to 20% more pounds of calf can be weaned from crossbred cows producing three-breed cross calves than straightbred cows producing straightbred calves. A more dramatic way of viewing this is to realize that 80 to 85 crossbred cows can be expected to wean the same pound of calf as 100 straightbred cows.

What are the advantages of crossbred cows?

Crossbred cows are more fertile than straightbred cows in that they have a greater percentage conceive to first service, they return to heat sooner after calving (under good management), and there is a greater survival of the embryo prior to birth. All of these advantages result into about a 6% increase in number of calves born over a straightbred cow. Again, the greater livability of crossbred calves is present and it appears that threebreed cross calves have greater livability than do twobreed crosses (about 2%); however, it is not as great as the advantage two breed crosses have over straightbred (about 4%). The crossbred cow also seems to be capable of responding to the heavy stimulation of crossbred calves and responds by giving additional milk. This results in heavier weaning weights of about 5% over two-breed cross calves and 10% over straightbred calves.

How does crossbreeding affect calves?

Table 1 summarizes the influence crossbreeding has upon number of calves born, number of calves weaned, and the average weaning weight of calves weaned. These data indicate that straightbred Angus, Hereford, or Shorthorn cows bred to a bull of a different breed (Angus, Hereford, or Shorthorn) so as to produce a crossbred calf respond with only a slight increase in number of calves born (about 1%) but there is a 4% increase in number of calves weaned and they wean off at about 5% heavier than straightbred calves under the same management. The increase in numbers of calves born (4%) and weaned (4%) when crossbred is due to a greater livability of the crossbred calf as compared to straightbred calves. Greater livability of crossbred calves becomes obvious within the first week to ten days after birth. The crossbred calf, compared to a straightbred, is more hardy and aggressive. They stand, nurse earlier and are more resistant to the calfhood stresses such as chill and scours. Advantages of more aggressiveness also contributes to the increase in weaning weights of crossbred calves. Crossbred calves appear to stimulate the cow more than straightbred calves by more frequent and longer nursing. This leads to an increase in milk flow, which has the net result of heavier weaning weights.

What is the correct name for the phenomenon that causes crossbred individuals to have an increased level of performance for certain traits?

Heterosis is the correct name for the phenomenon that causes crossbred individuals to have an increased level of performance for certain traits over and above the average performance of their straightbred parents. Heterosis does not necessarily imply that the crossbred progeny will have increased performance over the most superior of the two straightbred parents.

Why are crossbred calves more aggressive?

Advantages of more aggressiveness also contributes to the increase in weaning weights of crossbred calves. Crossbred calves appear to stimulate the cow more than straightbred calves by more frequent and longer nursing. This leads to an increase in milk flow, which has the net result of heavier weaning weights.
