Nutritional Management during Gestation: Impacts on Lifelong Performance
نویسندگان
چکیده
Effective nutritional management during gestation has long been recognized as an important component of sound livestock production practices (Bull and Carroll, 1937; Barcroft, 1946; Morrison, 1949; Maynard and Loosli, 1956; Crampton and Lloyd, 1959; NRC, 1970). Recent observation in the area of developmental programming (Barker et al., 1992; Barker et al., 1993; Godfrey and Barker, 2000; Barker, 2004) has elevated the concept of maternal onset of adult disease and lifelong performance to the forefront of investigation in several national and international laboratories. In addition, the 2007 Aspen Perinatal Biology Symposium http://www.med.uc.edu/obgyn/aspen/index.html and the 2007 5th International Congress on Developmental Origins of Health & Disease, which is sponsored by the International Society for Developmental Origins of Health and Disease http://www.congresswest.com.au/dohad/index.html both focus on developmental programming and have major sections that highlight relevance in animal agricultural. Clearly, research in these directions with livestock species (and other animal models) has and will likely continue to produce relevant data for both livestock and biomedical interests. In this report, several aspects of existing data with livestock species are reviewed and potentially relevant aspects to both livestock management and biomedicine are highlighted. The importance of nutritional management during gestation in regards to fetal programming, livestock production, and human health are addressed. Impacts of nutritional management during gestation on outcomes during the peri-conceptional period, fetal growth and development, birth to weaning, and weaning to adulthood are also discussed.

The objective of this study was to investigate the lifelong effect of in utero nutrition fed at different stages of pregnancy in Bali cows (n = 40): (U1) without in utero nutrition (0 – parturition, negative control); (U2) 0 – 90 d of gestation; (U3) 90 180 d of gestation; (U4) 180 d – parturition; and (U5) in utero nutrition along gestation period (0 d to parturition – positive control) on the...
متن کاملEffect of Flushing on the Growth, Body Condition Score and Reproductive Efficiency of Corriedale Ewes during Breeding Season and Gestation Period
The present study was aimed to improve the reproductive performance of Corriedale ewes by nutritional flushing. Forty Corriedale ewes were divided into four treatment groups (TC, T1, T2 and T3) with 10 ewes in each group (n=10). At the beginning of the breeding season extra feeding (flushing regime) was started for approximately 34 days such that two estrus cycles were covered. First group i.e....

IMPLICATIONS Research has suggested that maternal under-nutrition may cause the development of a thrifty phenotype in the offspring, potentially resulting in greater adiposity and reduced muscle mass. These potential alterations in fat and muscle development could have lasting impacts on offspring growth, carcass characteristics, and meat quality. Thus, the objective of this research was to det...
متن کاملNutrition and Feeding for Optimum Reproductive Performance
Since 1970, sow reproductive performance and prolificacy has improved dramatically. Today’s sow is genetically quite different. She is larger framed, with less back fat and more lean body tissue, besides having higher reproductive demands. The prolific, high-lean sow can raise more pigs per year, but also produce more milk resulting in heavier pigs at weaning. However, swine operations have a h...
متن کاملFeeding Management of Broodmares
Introduction an optimal broodmare feeding program will consider the maintenance of the mare, the growth and development of the fetal foal, and the production of milk. The impact of a broodmare feeding program can be substantial on not only the health of the mare, but also the development of the foal and the future equine athlete. The nutritional requirements of the broodmare vary depending on h...
