If we compare the two groups of 1,100-pound heifers mentioned above, we note that those calving at 24 months or less averaged 2.02 pounds per day (24.97-22.95) more than those calving at 25-26 months of age. However, this becomes a dif ference of 4,357 pounds during the total lifetime and, if milk sells for $6.50 per hundredweight, it has a value of $283. In other words, this is the additional income which can be realized by achieving 1,100 pounds body weight two or three months sooner. The value of a good calf and heifer raising program cannot be over emphasized.

Alan Bair. ~>S mm Assistant Connty Agricultura Agent 714 697 691 Rapid Growth and Early Calving Are Important In Dairy Heifers A long range study of various dairy management practices is nearing completion at The Pennsylvania State University. The study was started several years ago by Harvey E. Shaffer, Extension dairy specialist and was designed to determine the effects of certain management practices on the performance of cows throughout their entire lifetime. The study involved 2,365 Holstein cows, all starting as first-calf heifers in 1961 and they were in 217 herds selected at random. Of the cows, 17 are still living, but some conclusions can safely be drawn at this time. Two of the factors being studied are age and weight of heifers at first freshening. Although the weights were no doubt estimated in most in stances, the data clearly show that first-calf heifers weighing 1,100 pounds are more efficient producers than those that are either larger or smaller. They live longer, produce more milk in their lifetime, and have a higher average production per day of life. It might be assumed that many of the heavier heifers were too fat and it is possible that 1,200 pound heifers would perform better if they were grown properly. However, this is speculation. The study also shows a definite advantage for heifers freshened at an early age, even as young as 22 months. It is true that older heifers at first calving actually live longer, but for each ad ditional month of age at first calving, there is a gain of only about 20 days in total life. In terms of total lifetime production and production per day of life, there is a definite and marked advantage for heifers freshened at 24 months or younger. When we consider the com bined effects of age and weight, the results are even more interesting. The most efficient combination of age and weight was 24 months and less at a weight of 1,100 pounds. These cows produced an average of 24.97 pounds per day of total life (figured from birth). The second highest average was 23.69 pounds per day for heifers 25-26 months old and weighing 1,200 pounds. Next highest was the group 25-26 months old weighing 1,100 pounds with an average of 22.95 pounds per day. By contrast, the heifers freshened at 31-32 months of age and weighing only 1,100 pounds averaged'just 19.10 pounds per day. 712 687 708 625 707 704 700 698 644 637 685 620 680 678 679 663 678 678 638 622 621 677 673 658 656 673 668 639 667 667 663 r?n n
