best time to breed cows
This will ensure she's big enough and her hips are wide enough to survive the birth process. Last Updated: November 20, 2019 This is completely contrary to the effects of cold on performance in winter-born calves in northern states where temperatures are more severe and high death loss and the potential for low growth rate in calves are major concerns. If I have heifers and cows running together, should I separate the heifers to run with bulls first? The author expresses his thanks to Dr. Tom Troxel, Cooperative Extension Service, University of Arkansas, for supplying data on cow size. This article was co-authored by Karin Lindquist, a trusted member of wikiHow's community. Pregnancy rates improved when the herd owners corrected their management practices. Table 6 shows the effect of month of birth on calf performance. Thanks to all authors for creating a page that has been read 386,014 times. Research has shown that this reduction in fertility is a result of heat stress brought on by high temperature and humidity that combine to raise the temperature/humidity index. If calves born in cooler months perform better than those born in summer, then what effect is there on performance of calves born in the cold of December, January and February? In general, the information can be applied to herds in the eastern, southeastern, south central and southern regions of Texas. Karin Lindquist earned a BSc in Agriculture as an Animal Science major from the University of Alberta, Canada. Heifers should be bred when they have had at least 3 heat periods after the initial start of puberty, no matter what the breed. Research has shown that this reduction in fertility is a result of heat stress brought on by high temperature and humidity that combine to raise the temperature/humidity index. If nothing else, data in Table 5 indicate that proper nutrition is required and that temperatures during Central Texas winters are not so stressful that fertility is compromised. Perhaps the most important thing to conclude from data in Table 6 is that stressful temperatures of both cold and heat will affect calf performance, and summer calving is not recommended in the eastern, central, southern and Gulf Coast regions of Texas. On the other hand, if you are using a British bull on British cows (and it doesn't necessarily have to be the same breed), you can still get a bit careless with calving ease and still end up with problems. For more tips from our Agricultural co-author, including how to choose a bull for your cow to breed with, read on! Heat stress in cows is known to cause hormone imbalances, reduced quality of ova, early embryo death and reduced blood flow to the uterus. Consequently, pregnancy rates are high in herds that have a high proportion of cows showing estrus early in the breeding period. Occasionally, though, some heifers that are bred too early are able to pass and raise a calf without human interference, either at calving or during the period the calf is being raised. wikiHow is where trusted research and expert knowledge come together. If nothing else, data in Table 5 indicate that proper nutrition is required and that temperatures during Central Texas winters are not so stressful that fertility is compromised. Every tip and answered question helped a bunch. The data show that growth performance drops in calves born in May through September.

Fall-born calves will be marketed in the spring and calves born in the spring will be marketed in the fall unless the producer can retain ownership of calves past weaning. A heifer will no longer be a heifer after she has had her second calf where she becomes a Cow: a female MATURE bovine that has had two calves. However, there are breeding and calving dates that probably should be avoided because differences in climate in regions of Texas can affect the availability and conditions of pasture needed for nutrition of pregnant cows and calves. These data suggest that unless alternative nutritional management steps can be taken to reduce feed costs in large frame, fall calving cows, it is best to calve such cows in the spring. Breeding Heifers Heifers, or young cows who have not yet given birth to any calf, should be bred at the same time as the other cows to ensure the same calving schedule can be maintained among the herd. Observations prior to milking are a good, practical time when cows are intermingling and sexually active groups are easily detected. Data from an Arkansas trial show that calf performance and profits are best in small to medium frame cows that calve in the fall compared to spring months. However, Table 5 shows that Central Texas cows exposed for breeding during November, December and January have acceptable reproductive performance. Be wary around bulls during breeding season. It's critical in timing everything right to make AI successful for her. Normal estrus periods last 24 hours and occur between 17 to 24 days. Approved. It would be a good idea to do so.

Arrange it so that your heifers are bred one to two weeks ahead of your cows so that the heifers are calving out a week or two before the cows. Even then, data from a fourth Gulf Coast herd with summer calves (not shown) revealed that growth rate in summer calves was low, which forced them to be kept until 12 months of age to reach an acceptable sale weight that their herd mates reached at 7 months of age. It would be best to call your vet to determine if the bull is infertile, or the cow has something going on causing her to not catch a calf. Unfortunately, data concerning pregnancy rate at first estrus during the cold months in Texas are not available. She has over 20 years of experience working with cattle and crops. If cows are wintered on hay, spring pasture offers the best feed for breeding season and spring calving is a better choice. Thanks, and keep up the good work! Table 6 shows that calves born in those months also suffer, but not to the same degree as those born in hot months. Click for a hub of Extension resources related to the current COVID-19 situation. Cows calving in the fall normally need more supplemental feed in the winter, unless cool season pastures are used, than do cows that calve in … Carcass maturity is when bone and muscle growth plateau's off and fat begins to be laid down. In contrast, high humidity in eastern, southeastern and Gulf Coast regions of Texas suggests that summer breeding may not be advisable. There are rare instances of heifers continuing to stand even though they are pregnant, but it is uncommon. This article was co-authored by Karin Lindquist, a trusted member of wikiHow's community.
