THE PROMISE

_________________________

Genesis 18:10-14 (NRSV)

Then one said, "I will surely return to you in due season, and your wife Sarah shall have a son." And Sarah was listening at the tent entrance behind him. Now Abraham and Sarah were old, advanced in age; it had ceased to be with Sarah after the manner of women. So Sarah laughed to herself, saying, "After I have grown old, and my husband is old, shall I have pleasure?" The LORD said to Abraham, "Why did Sarah laugh, and say, 'Shall I indeed bear a child, now that I am old?' Is anything too wonderful for the LORD? At the set time I will return to you, in due season, and Sarah shall have a son."

_________________________

Is anything too hard for the LORD?

-- Genesis 18:14 (NIV)

_________________________

THE argument was loud. Our words flew across the room and hit like boulders. "One day," I promised, "you will know that nothing you do will stop me from loving you." My daughter's unbelieving laughter put me to the test.

Remembering God's promise to Sarah and her unbelieving laughter, I reflected on God's faithfulness. God fulfilled the promise even when Sarah's faith failed. I needed to fulfill my promise in the face of my daughter's doubt. All I needed was God's help, opportunities, and time.

Opportunities came; and with each encounter, my daughter's resistance dissolved a little bit more. Just as God kept the promises to be with me, to teach me, and to reach out in love to me especially when I was rebellious, so I have been able to keep my promise to love my child. In time, God worked in our circumstances to bring about trust, respect, and love.


Prayer: God, remind us each day that nothing is too hard for you.
Amen.


THOUGHT FOR THE DAY:
God's faithfulness is our model for how to love.

Selenium and the Horse



Selenium is a trace element required by the horse.
Selenium is not manufactured by plants, but is absorbed by them from the earth. If the soil is low in selenium then it is likely that both hay and oats grown on it will also have a low content . Most soils are not low in Se but some are.

Main electrolytes : Na K Ca Mg Chloride Phosphate
Trace Elements : Fe Cu Zn Co selenium S I

To check on the electrolyte levels of a horse is not straightforward; Blood Plasma Concentration gives an overall guide to electrolyte/mineral levels, but will only detect large deficiency or excess. However horses are very capable of maintaining plasma levels to the detriment of tissue levels therefore a combined blood urine analysis may be better. Even so it is not easy to analyse out a trace of selenium in comparison to a main electrolyte such as Sodium. Possible but difficult, therefore probably expensive!

Most equine diets have a natural excess of electrolytes.

BUT soils deficient in selenium may cause problems for horses especially broodmares youngstock .

Selenium is a key part of the blood cell enzyme glutathione peroxidase which in conjunction with vit E, removes free radicals {very reactive damaging substances that are sometimes formed within cells, see below} from the body. Selenium and/or Vit E deficiency have been shown to cause muscle disease in young horses.

Substantial excess Selenium is TOXIC.

Toxicity is partly due to selenium replacing sulphur in proteins, typically causing diseased hoof horn, known as alkali disease. If poisoning is acute then death occurs due to organ damage, especially the liver. Some plants e.g.. vetch can contain selenium at up to 6000ppm, this is considered sufficient to cause acute poisoning if eaten in any quantity.

Quotes for absolute daily requirement appear contradictory, but in the UK, where Se additives are not necessary under normal conditions the herbage typically contains 0.1 mg per kg of dry matter.

Therefore it doesn't seem unreasonable to conclude that a possible inclusion rate for an adult horse would be 1mg per day as a feed supplement. Youngstock typically require a greater level of trace elements than adults, but given the nature sensitivity of Selenium in the diet, I would not be inclined to exceed this level unless professionally advised to do so.

Selenium requirement action is known to vary with VitE levels, therefore a supplement that contains both VitE Selenium would seem sensible. A few years ago I did feed one such supplement to help a mare recover from a skin hair infection. My observations aren't scientifically based, but it did seem to help her.
