“…Maternal dietary protein restriction, at the moderate level used in this study, is commonly observed in commercial cattle operations (Bortolussi et al 2005). We have previously shown that such restriction alters productivity traits in the progeny (Micke et al 2010a(Micke et al , 2011 and have reported that both postnatal reproductive development (Copping et al 2018) and meat quality traits (Alvarenga et al 2016) were affected in the entire male progeny from the present study. Information presented in this study may provide insights into the underlying molecular pathways that promote susceptibility to increased fat deposition in the growing animal subsequent to protein restriction during early oocyte and/or embryo development.…”

Few studies have investigated the effects of nutrition during the periconception and early gestation periods on fetal and placental development in cattle. In this study, nulliparous yearling heifers (n=360) were individually fed a diet high or low in protein (HPeri and LPeri) beginning 60 days before conception. From 24 to 98 days after conception, half of each treatment group was changed to the alternative high- or low-protein diet (HPost and LPost) yielding four groups in a 2×2 factorial design. A subset of heifers (n=46) was necropsied at 98 days after conception and fetoplacental development assessed. Placentome number and volume decreased in response to LPeri and LPost diets respectively. Absolute lung, pancreas, septum and ventricle weights decreased in LPost versus HPost fetuses, whereas the post-conception diet altered absolute and relative liver and brain weights depending on sex. Similarly, changes in fetal hepatic gene expression of factors regulating growth, glucose output and lipid metabolism were induced by protein restriction in a sex-specific manner. At term, neonatal calf and placental measures were not different. Protein restriction of heifers during the periconception and early gestation periods alters fetoplacental development and hepatic gene expression. These changes may contribute to functional consequences for progeny, but this may not be apparent from gross morphometry at birth.

“…The pH 45min (pH value at 45 min postmortem) and pH 24h (at 24 h postmortem) values were measured using a pH meter (205, Testo SE & Co, Freiburg, Germany), which was calibrated at the beginning of each measuring day using pH 4.6 and 7.0 buffers. The meat color was measured using a chroma meter (CR-400, Konica Minolta Group, Tokyo, Japan) that was calibrated against a standard white plate (8-mm-diameter aperture, d/0 illumination system) according to the Commission Internationale de I’Éclairage (CIE) L* (lightness), a* (redness), and b* (yellowness) system at 45 min (L* 45min , a* 45min and b* 45min ) and 24 h (L* 24h , a* 24h and b* 24h ) postmortem, as described by Alvarenga, et al [16]. The average values of pH and color were determined after measuring three times at three locations on the ventral surface of the muscle.…”

Nutritional status during mid-gestation is often ignored under extensive husbandry. This study aimed to examine the effect of maternal undernutrition during mid-gestation on kid meat production under an extensive system. Twenty-seven goats (45 ± 3 d of gestation) were randomly assigned to an unrestricted group (100% of nutrient requirements), or a restricted group (60% of nutrient requirements from 45 to 100 d of gestation, and then re-alimented to 100%). Among the offspring, 16 eligible kids (eight per treatment) were selected, based on birth type and survival, and were harvested to evaluate the meat yield, quality, and composition at 90 d after birth. Maternal undernutrition reduced the body weight and size, average daily gain and hot carcass weight of the kids (p < 0.05). The lightness of the meat at 45 min postmortem was increased (p = 0.029) in the restricted kids. Apart from an increase in tyrosine concentration (p = 0.046), the proximate composition and the amino acid and fatty acid profiles were unaffected in the restricted kids (p > 0.05). Overall, maternal undernutrition during mid-gestation decreased the yield of kid meat, but did not significantly modify the quality and composition. These results highlight the importance of nutrient status during mid-gestation in the meat production of small ruminants under an extensive regime.

“…Low maternal dietary protein intake (7% CP) resulted in offspring with semitendinosus muscles that had a higher shear force and lower collagen content, indicating an adverse effect of maternal malnutrition on the meat quality of male offspring. 24 Restriction of maternal protein intake during the second trimester decreased birth weights of calves even when Table 2.

Maternal nutrition during gestation, especially dietary protein intake, is a key determinant in embryonic survival, growth, and development. Low maternal dietary protein intake can cause embryonic losses, intra-uterine growth restriction, and reduced postnatal growth due to a deficiency in specific amino acids that are important for cell metabolism and function. Of note, high maternal dietary protein intake can also result in intra-uterine growth restriction and embryonic death, due to amino acid excesses, as well as the toxicity of ammonia, homocysteine, and HS that are generated from amino acid catabolism. Maternal protein nutrition has a pronounced impact on fetal programming and alters the expression of genes in the fetal genome. As a precursor to the synthesis of molecules (e.g. nitric oxide, polyamines, and creatine) with cell signaling and metabolic functions, L-arginine (Arg) is essential during pregnancy for growth and development of the conceptus. With inadequate maternal dietary protein intake, Arg and other important amino acids are deficient in mother and fetus. Dietary supplementation of Arg during gestation has been effective in improving embryonic survival and development of the conceptus in many species, including humans, pigs, sheep, mice, and rats. Both the balance among amino acids and their quantity are critical for healthy pregnancies and offspring. Impact statement This review aims at: highlighting adverse effects of elevated levels of ammonia in mother or fetus on embryonic/fetal survival, growth, and development; helping nutritionists and practitioners to understand the mechanisms whereby elevated levels of ammonia in mother or fetus results in embryonic/fetal death, growth restriction, and developmental abnormalities; and bringing, into the attention of nutritionists and practitioners, the problems of excess or inadequate dietary intake of protein or amino acids on pregnancy outcomes in animals and humans. The article provides new, effective means to improve embryonic/fetal survival and growth in mammals.
