Document Summary
Nutritional programming has huge impact for generations to come. Royal jelly programs which genes are being expressed. Even though all the bees are clones (have same genome) How we feed them early on will impact them throughout their whole life. Loosening the dna a little around a histone can increase its chances to be transcribed. Pregnant cows are not doing too well during late pregnancy. Beef cows are on restricted diets because of poor pasture covered in snow. The amount of muscle cells an animal will have is predetermined before birth. Cows that are heat stressed when getting pregnant will produce less milk.

The amount of colostrum being fed in the 1st few hours of life has a lasting effect. If you have more methyl groups added on the transcription factors can"t bind as easily to the promote and transcribe that gene.
