Nutritionally-directed compensatory growth enhances mammary development and lactation potential in rats.
A nutritionally-regulated compensatory growth regimen imposed during a growing period from prepuberty to gestation can significantly affect mammary development and subsequent lactation performance. The objectives of this study were as follows: 1) to determine whether a compensatory nutrition regimen enhances lactation potential for the first and second lactation cycles and 2) to determine the e...
متن کاملEffects of Controlled Compensatory Growth on Mammary Gland Development and Lactation in Rats
The objective of this study was to examine the effect of compensatory growth nutritional regimen on mammary gland growth and lactation. One hundred twenty-two Sprague Dawley female rats (35 days of age) were randomly assigned to either a control or a stair-step compensatory nutrition (SSCN) feeding regimen or an alternating 2-2-3-3-week schedule beginning with 40% energy restriction for 2 weeks...
متن کاملProduction performance of beef cows raised on three different nutritionally controlled heifer development programs.
The objective of this study was to determine primiparous heifer performance following three different heifer development strategies that were the result of timed nutrient limitation. Two hundred eighty-two spring-born MARC III heifers were weaned at 203+/-1 d of age and 205+/-1 kg BW. The experiment was conducted on two calf crops with 120 heifers born in 1996 and 162 heifers born in 1997. Trea...

متن کاملRole of compensatory mammary growth in epigenetic control of gene expression.
To better understand the role of nutrition in regulating mammary gland development and lactation, we designed a novel stair-step compensatory nutrition regimen that is a unique combination of dietary energy restriction and realimentation (refeeding) phases; the basic concept of this regimen is to exploit the biological nature of the compensatory growth phenomenon in concert with one or more hor...
