“…Undernutrition often results in offspring that are small for gestational age, culminating in smaller birth weights followed by a compensatory response during postpartum growth in sheep and cattle [ 19 , 20 , 21 ]. The observed reduction in birth weights may be due to a prioritization of vital organs over the development of muscle mass in animals that are exposed to nutrient restriction in utero .…”

“…Ford et al [ 26 ] found glucose intolerance in male lambs following a glucose tolerance test at 12 months of age following exposure to maternal undernutrition; however, the study did not compare male and female lambs. Similarly, beef steers exposed to different levels of nutrient restriction in utero had increased average daily gain consistent with compensatory growth, but heifer offspring were not included in the study [ 21 ].…”

Poor maternal nutrition can cause several maladaptive phenotypes in exposed offspring. While non-sex-specific and female-specific adaptations are well-documented, male-specific outcomes are still poorly understood. Of particular interest are the outcomes in bulls and rams, as developmental programming directly impacts long-term productivity of the animal as well as human food security. The following review discusses the impact of poor maternal dietary energy and protein on bull and ram developmental programming as it relates to growth, development, and reproductive capacity. The review also highlights the importance of the timing of maternal dietary insult, as early-, mid-, and late-gestational insults can all have varying effects on offspring.

“…Além disso, pode ocorrer crescimento compensatório do feto após o nascimento, devido maior capacidade de adaptação em ambientes desafiadores na criação. Ramírez et al (2020) observaram que uma restrição nutricional severa pode induzir uma compensação no crescimento da prole bovina, frente as progênies de vacas com nutrição adequada ou restrição moderada na gestação.…”

O objetivo deste trabalho foi, através de uma revisão de literatura, identificar as principais alterações fisiológicas e comportamentais causadas pela programação fetal que afetam a saúde e o desempenho da progênie na vida pós-natal. Dentre os inúmeros fatores que alteram a formação fetal, a nutrição materna na gestação tem sido fortemente referenciada nas pesquisas recentes. A nutrição materna na gestação pode alterar de inúmeras formas a formação fetal, de forma que o feto se adapte o mais rapidamente possível ao ambiente uterino, sendo essas mudanças perceptíveis durante a vida adulta da progênie. De modo geral, a literatura sugere que a restrição materna na gestação pode promover mudanças fisiológicas e funcionais nos órgãos e tecidos do feto, preparando o organismo para sobreviver em ambientes desafiadores também na vida pós-natal. Além disso, indivíduos que experimentaram ambientes restritos durante a formação fetal, apresentam maior procura por alimento e comportamentos psicossociais alterados, tais como reações de medo, isolamento e reatividade. A maior eficiência produtiva e consequentemente menor idade de abate da progênie tem sido associada a melhor nutrição materna durante a gestação, uma vez que esses indivíduos possuem formação fetal adequada e, portanto, maior capacidade metabólica dos nutrientes em sistemas intensivos de produção que almejam o máximo desempenho animal.

“…IUGR alters the proliferation and differentiation of myoblasts prepared from near-term sheep fetuses [ 14 ] and the proportion of type I (oxidative) and II (glycolytic) myofibers, the two major matured muscle cell types in the skeletal muscle tissue [ 15 , 16 , 17 ]. Fetal muscle growth impairment in meat animals can affect livestock production, especially meat quality parameters such as beef tenderness [ 18 , 19 ]. The intramuscular triglyceride content is upregulated in the nutrition-restricted fetal skeletal muscles [ 16 ].…”

Maternal Undernutrition during Pregnancy Alters Amino Acid Metabolism and Gene Expression Associated with Energy Metabolism and Angiogenesis in Fetal Calf Muscle

To elucidate the mechanisms underlying maternal undernutrition (MUN)-induced fetal skeletal muscle growth impairment in cattle, the longissimus thoracis muscle of Japanese Black fetal calves at 8.5 months in utero was analyzed by an integrative approach with metabolomics and transcriptomics. The pregnant cows were fed on 60% (low-nutrition, LN) or 120% (high-nutrition, HN) of their overall nutritional requirement during gestation. MUN markedly decreased the bodyweight and muscle weight of the fetus. The levels of amino acids (AAs) and arginine-related metabolites including glutamine, GABA, and putrescine were higher in the LN group than those in the HN group. Metabolite set enrichment analysis revealed that the highly different metabolites were associated with the metabolic pathways of pyrimidine, glutathione, and AAs such as arginine and glutamate, suggesting that MUN resulted in AA accumulation rather than protein accumulation. The mRNA expression levels of energy metabolism-associated genes, such as PRKAA1, ANGPTL4, APLNR, CPT1B, NOS2, NOS3, UCP2, and glycolytic genes were lower in the LN group than in the HN group. The gene ontology/pathway analysis revealed that the downregulated genes in the LN group were associated with glucose metabolism, angiogenesis, HIF-1 signaling, PI3K-Akt signaling, pentose phosphate, and insulin signaling pathways. Thus, MUN altered the levels of AAs and expression of genes associated with energy expenditure, glucose homeostasis, and angiogenesis in the fetal muscle.
