Share Facebook Twitter Google + LinkedIn Pinterest Because of a perfect storm of vitamin production problems, supplemental vitamins A and E are becoming scarce and prices are skyrocketing. Supplies probably will remain very tight well into summer of 2018. In this time of high vitamin prices and limited supply, vitamin supplementation strategies should be evaluated. The most recent dairy NRC (2001) has a vitamin A requirement of 50 IU of supplemental vitamin A/lb of body weight. For an average Jersey and Holstein cow, that translates to about 50,000 and 70,000 IU/day, respectively. That requirement is also for dry cows and growing heifers. For supplemental vitamin E, NRC recommendations are 0.35 IU/lb of body weight for lactating cows and 0.7 IU/lb of body weight for dry cows. This is approximately equal to 500 and 1000 IU/day of supplemental vitamin for lactating and dry Holstein cows and 350 and 700 IU/day for lactating and dry Jersey cows, respectively. Surveys have indicated that supplementation rates are commonly at least twice NRC recommendations.Several controlled studies have shown that feeding vitamins A and E at NRC recommendations reduce mastitis, abortions, retained placenta, and metritis compared to feeding diets with no supplemental vitamin A or E. However, essentially no data are available showing that feeding more vitamins A and E than recommended has any additional positive effects. An exception is prefresh cows because for vitamins A and E, parturition is a critical time. Substantial amounts of those vitamins are put into colostrum and substantial amounts of those vitamins are metabolized during the process of parturition. Several studies have shown that increased supplementation of vitamin E during the last two or three weeks prepartum reduces mastitis. Supplementation rates ranged from 2000 to 4000 IU/day during the prefresh period. Similar data for vitamin A are not available.Recommended vitamin supplementation strategies:1. Feed vitamins A and E at NRC levels. In many situations, this will reduce vitamin supplementation by about 50%.2. If prices continue to climb and vitamins become scarce, then:Prefresh cows should be the highest priority and be maintained at NRC levels for vitamin A and probably 2000 IU/day for vitamin E. A prefresh period of 2 or 3 weeks is adequate with respect to these vitamin recommendations.If you do not have a separate prefresh group from the far-off dry cows, the next priority would be to meet NRC requirements for vitamins A and E for all dry cows.I would try to provide some supplemental vitamins A and E to all cows, but lactating cows would be the lowest priority. These cows consume a lot of feed and the feed is usually better quality than that fed to dry cows. Lactation diets can contain substantial basal vitamin E and B-carotene (precursor to vitamin A); therefore, they will be consuming more vitamins than dry cows. If vitamin A becomes very scarce, I think you can reduce vitamin A supplementation to about 50% of NRC for several months (all the past overfeeding of vitamin A has likely increased liver stores of retinol, which can be used to meet the vitamin A needs for an extended period of time). Likewise, vitamin E supplementation to lactating cows could probably be cut to 50% of NRC in the short term (a few months).Vitamin E supplementation of bred heifers can likely be reduced to well below NRC until about 60 days prepartum. Also, some vitamin A supplementation should be provided to these animals (perhaps 50% of NRC).
Share Facebook Twitter Google + LinkedIn Pinterest Dan Uetrecht, Warren CountyWe’ve been pretty slow like everyone else. We had close to three inches of rain the other day. I’ve lost track of all the gloomy, rainy cloudy days but one day and one night it never stopped raining. We got some higher winds but nothing that caused damage.The wheat looks good and is greening up some but it is behind like the grass and the trees. Normally we start seeing leaves the first week of April and there are no leaves on our trees down this way. I think everything is behind and waiting for some warm weather to start growing.I’m getting everything ready. We are cleaning fence line and doing all of those little things so whenever that window opens we can just hammer down. It is frustrating to be in the first part of April and be so wet.I have a little bit of wheat by a creek — we have some lower bottoms by a couple of big creeks. With that bottom ground we get high organic matter but we also get a lot of flooding. We had one whole wheat field under water for a day. There is still a little ponding there and some yellow spots, but nothing that I think is going to hurt the yield too much. We did topdress that wheat when it got a little drier. Hopefully we haven’t lost too much nitrogen. I think we are fine because we used an N inhibitor.I am a big believer in early planting. We have two planters so we can plant corn and beans at the same time. I think we can raise pretty good beans because we plant early. There has only been one time I can remember that frost has gotten the beans. When the soil temperature is right and conditions are right, we’ll plant. Any time around April 10 when things are right we will roll, but there is no way we will get out there by April 10.The cover crops are starting to grow a little and green up. We got the rye on late. We can’t plant now but we have crimson clover and rye coming up. They are starting to grow and you like to have something growing out there when you can’t do anything. The planters are hooked up and we are ready.For the rest of this week’s reports, click here.
With snakebites emerging as the leading cause of natural disaster deaths in Odisha, the State government has decided to ensure deployment of doctors at primary health centres in snakebite-prone areas and make ambulances available for swift transfer of patients to hospitals.As many as 1,716 people lost their lives due to snakebites during the past three years. The number of casualties due to snakebite, highest among all disasters, accounts for about 37% of the total disaster deaths (4,689) during the period.“We have asked the Health and Family Welfare Department to ensure availability of medical officers at primary health centres in snakebite-prone areas. Besides, required number of 108 ambulances will be made available in blocks for shifting snakebite patients to the nearest health institution,” said Bishnupada Sethi, Managing Director of the Odisha State Disaster Management Authority.The State government is working on a plan to bring all snakebite victims to the nearest health institution at the earliest for medical examination and administering anti-venom. Highest deaths The highest of 164 deaths has been reported from Balasore district, followed by 147 in Ganjam and 145 in both Keonjhar and Mayurbhanj during the period.
Prime Minister Narendra Modi on Wednesday alleged that the Congress praised controversial Islamic preacher Zakir Naik, “whose words have triggered blasts in Sri Lanka killing 300 people”, and its leaders were baying for his blood in their dream.Addressing an election rally here in Madhya Pradesh, he said the Rahul Gandhi-led party has nothing but hatred for him, but he has support of the entire country.“Zakir Naik’s words have caused blasts in Sri Lanka, leaving 300 people dead. His TV channel was banned two or three days ago,” Mr. Modi said.“Who is Zakir Naik? He is the one whom (Congress veteran) Digvijaya Singh used to glorify unabashedly. You will be shocked to learn that Zakir Naik addressed Indian police officers, that too on terrorism, under the (previous) Congress dispensation,” he said.“Shame on Congress… and its vote bank politics. They are glorifying Zakir Naik and calling him an apostle of peace,” he added.Naik, a Mumbai-based televangelist accused of inciting youth for terror activities and giving inflammatory speeches, is said to be currently residing in Malaysia.Apparently referring to a reported statement of Congress leader and former cricketer Navjot Singh Sidhu, the Prime Minister said, “I heard that a Congress motormouth leader came here and said hit Modi for such a six that he lands out of the boundary dead. This was the statement of a Congress leader. Think. They have so much hatred for your Modi, so much hatred that they have started dreaming of killing Modi.”‘India batting for Modi’ “But they are forgetting that from Modi’s side, not just the people of Madhya Pradesh but of entire India are batting,” Mr. Modi said.The PM said the Congress has to now clarify its position on terrorism. “The Congress people should reveal whether they are playing for India or Pakistan,” he said.
