Angus x Hereford heifers (15 mo and AI to a single sire) were used to evaluate the effect of prenatal nutritional restriction on postnatal growth and regulation of glucose in plasma. Dams (d 32 of gestation) were stratified by BW and BCS and allotted to low [LN, 55% of NRC (1996) requirements, n = 7] or moderate nutrition [MN, 100% of NRC (1996) requirements, n = 7]. After 83 d of feeding, dams were commingled and received a diet in excess of requirements. Dams were allowed to calve naturally…

The effects of late gestation nutrient restriction of dams on beef heifer intake, metabolites and hormones during an ad libitum feeding trial

Results show that nutrient restriction during late gestation alters appetite and endocrine regulation in heifer offspring.

Effects of Developmental Programming Caused by Maternal Nutrient Intake on Postnatal Performance of Beef Heifers and Their Calves

Early maternal subnutrition had long-term effects on heifer postnatal performance during the first four months of life which compromised heifer metabolic status during rearing but did not affect the reproductive performance during its first gestation and lactation periods of beef heifers.

Influence of excessive dietary protein intake during late gestation on drylot beef cow performance and progeny growth, carcass characteristics, and plasma glucose and insulin concentrations.

Investigation of the effects of excessive prepartum dietary protein intake on late gestation cow performance as well as subsequent progeny growth, carcass characteristics, and plasma glucose and insulin concentrations found feeding cows 129% of CP requirement during late gestation did not affect cow performance or progeny preweaning or finishing period growth.

Effects of feeding a high- or moderate-starch prepartum diet to cows on newborn dairy heifer calf responses to intravenous glucose tolerance tests early in life.

It is suggested that feeding a HI prepartum diet may reduce some insulin sensitivity indicators of female offspring early in life.

The effects of protein supplementation of fall calving beef cows on pre- and postpartum plasma insulin, glucose and IGF-I, and postnatal growth and plasma insulin and IGF-I of calves.

Increasing protein supplementation of fall calving beef cows from November to March, during breeding and early pregnancy, reduced BW loss of cows, decreased the interval from calving to pregnancy, increased plasma concentrations of insulin in December, January, and March, and increased plasma insulin-like growth factor-I in December without alteration in pregnancy rate.

The influence of maternal energy status during mid-gestation on growth, cattle performance, and the immune response in the resultant beef progeny1

Differences in cow energy status applied during mid-gestation in this experiment will not affect BW or growth performance differences throughout the postnatal period in beef cattle progeny but may have an effect on the adaptive immune response during their receiving period in calves.

Long-Term Effects of Maternal Subnutrition in Early Pregnancy on Cow-Calf Performance, Immunological and Physiological Profiles during the Next Lactation

Undernutrition in early gestation in suckler cows had long-term effects on offspring postnatal growth, this physiological evidence being more severe in Pirenaica cow-calf pairs.

Effects of prepartum protein nutrition and birth weight on basal metabolism in bovine neonates.

It is concluded that the thermogenic ability of neonatal calves may be compromised by prepartum protein restriction and(or) small birth weights.

Effects of early gestational undernutrition on fetal growth, organ development, and placentomal composition in the bovine.

A bout of fetal IUGR may go undetected if cows undernourished during early gestation receive feed supplementation in the second half of gestation to assure normal birth weight.

Maternal undernutrition during early to mid-gestation in the ewe results in altered growth, adiposity, and glucose tolerance in male offspring.

It is demonstrated that a bout of maternal undernutrition during early to midgestation in sheep increased BW and fat deposition during adolescence and dysregulated glucose uptake in the absence of any change in birth weight.

Influence of prepartum nutrition on the reproductive performance of beef females and the performance of their progeny.

Two experiments were designed to assess the importance of maternal nutrition in the later stages of gestation on reproductive performance of beef females and on the growth and survival of their calves and there was a tendency for a higher percentage of adequately-fed heifers to show estrus by 40 days postpartum.

Pregnant undernutrition, specifically during late gestation, affects adult offspring intermediary metabolism, and, in particular, glucose-insulin homeostasis in sheep, which was unaffected by fetal number.

Effects of body composition, pre- and postpartum energy level and early weaning on reproductive performance of beef cows and preweaning calf gain.

Results suggest that fleshy and thin cows at parturition should be managed to approach moderate body condition before the breeding season to optimize reproductive performance and preweaning calf gain.

Effects of dam age, prepartum nutrition and duration of labor on productivity and postpartum reproduction in beef females.

Results of this study indicate prolonged labor may result in depressed subsequent reproduction in beef dams and short duration of labor had beneficial effects on postpartum reproduction in both dam age groups.

Reproductive responses and calf birth and weaning weights as affected by body condition at parturition and postpartum weight gain in primiparous beef cows.

Greater BCS at calving resulted in more cows in estrus and more cows pregnant by 40 and 60 d of a breeding season, and no significant interactions among location, BCS, or postpartum nutrition-group were observed for any of the production variables described above.

The effect of nutritional restriction of Hereford heifers in late pregnancy.

It is suggested that heifers should be fed to allow modest rates of bodyweight gain (0--0.5 kg/day) during late pregnancy.

Flock differences in the impact of maternal dietary restriction on offspring growth and glucose tolerance in female offspring.

The data suggest that a multigenerational adaptation of ewes to different production systems impacts their ability to protect their fetus against a bout of early to mid-gestational nutrient restriction.
