We aimed to investigate the effects of maternal protein restriction during mid-gestation on skeletal muscle composition offspring. In treatment (RES, n = 9), cows were fed a basal diet, while in control (CON, 9) group received same RES diet plus supplement (100–200d). Samples Longissimus dorsi collected from offspring at 30d and 450d postnatal. Muscle fiber number was found be decreased as result persisted throughout offspring’s life (p < 0.01). The collagen content enhanced 0.05) due...
Since nutritional requirements are increased at the end of gestation to meet demands pregnant uterus, beef cows susceptible mobilization body reserves (mainly fat and amino acids (AAs)) alter metabolism nutrients in liver muscle support such demands. The objective this study was evaluate effect CP supplementation on maternal nutrient late grazing a low-quality pasture. Forty-three Nellore gestating male fetuses (average age = 6 years; average weight 544 kg) 193 ± 30 (mean SD) days (d) were...
Abstract This study aimed to quantify the effects of physiological status (PS) and potential interaction this factor with days pregnancy (DOP) on beef heifers’ weight variation, intake, digestion kinetics. Twelve rumen-cannulated zebu heifers (n = 7 pregnant; n 5 non-pregnant) were used. Heifers placed in individual pens fed medium-quality corn silage plus a protein-based supplement. Heifers’ body was assessed at beginning end each collection period. The feed intake measured daily. Target...
Twenty-four pregnant Nellore primiparous grazing cows were used to evaluate the effects of energy-protein supplementation and frequency during pre (105 d before calving) postpartum after on performance metabolic characteristics. Experimental treatments consisted a control (no supplementation), daily (1.5 kg/d concentrate/animal) infrequent (4.5 kg concentrate/animal every three days). During periods, concentrations blood metabolites animal evaluated. Ureagenesis energy metabolism markers...
The productive traits of beef cattle are orchestrated by their genetics, post-natal environmental conditions, and also the intrauterine background. Both under- or overnutrition, as specific dietary components, able to promote persistent effects on offspring. This occurs because factors act not only affecting availability substrates for fetal anabolism oxidative metabolism, but signals that regulate several events toward development. Therefore, this study aimed summarize gestational nutrition [...]
Abstract BACKGROUND Vitamin A has been reported as a factor influencing marbling deposition in meat from animals. Although the mechanisms by which vitamin regulates lipid metabolism mature adipocytes are already well‐established, information regarding molecular underlying effects of on regulation intramuscular fat beef cattle still remains limited. The present study aimed to assess involved supplemented with during fattening phase using proteomic approach. RESULTS supplementation decreased...
Abstract The current study aimed to determine the enriched biological processes, through proteomic and transcriptomic data, associated with maternal slow-release nitrogen diets received during late gestation their effects on skeletal muscle of offspring. From d 180 268 gestation, a total 16 pregnant Brahman cows were divided into two groups: control (CON, n = 12) low crude protein (CP) basal diet (6% CP, ad libitum) plus mineral mixture (130 gּ cow-1ּ d-1), or CON treatment supplemented...
We aimed to evaluate the effects of post-ruminal supply urea (PRU) on nutritional status, and liver metabolism pregnant beef cows during late gestation. Twenty-four Brahman dams, from a single sire, weighing 545 kg ± 23 were confined into individual pens at 174 d gestation, randomly assigned one two dietary treatments up 270 gestation: Control (CON, n = 12), consisting basal diet supplemented with conventional urea, where fed diets containing 13.5 g per dry matter; PRU (PRU, coated...
Dietary l-arginine (ARG) supplementation has been studied as a nutritional strategy to improve reproductive performance of pregnant sows, since arginine is conditionally essential amino acid. However, reports addressing the molecular mechanisms that mediate effects on embryos and fetuses development are still scarce. Therefore, we aimed evaluate 1.0% ARG commercial gilts genes proteins from energy metabolism antioxidant defense pathways in fetuses. We also analyzed global transcriptome...
We aimed to evaluate the performance, carcass and pork quality traits, as well mRNA expression of genes related intramuscular fat deposition in female pigs from different genetic lines. A total eighteen (Large White × Landrace Duroc Pietrain) Landrace) (Hybrid) averaging 88.96 ± 3.44 kg body weight twelve (Duroc) 85.63 1.55 were assigned a completely randomized design experimental trial that lasted 45 days. Pigs both lines received same diet, which was initially adjusted for their...
Since pre- and postnatal development are programmed during early prenatal life, studies addressing the complete transcriptional landscape organogenesis needed. Therefore, we aimed to disentangle differentially expressed (DE) genes between fetuses (at 35 days old) embryos 25 through RNA-sequencing analysis using pig as model. In total, 1705 were DE, including top DE IBSP, COL6A6, HBE1, HBZ, HBB, NEUROD6 genes, which associated with developmental transition from fetuses, such ossification,...
We aimed to investigate the effects of maternal plane nutrition during gestation on proteome profile skeletal muscle newborn. Pregnant goats were assigned following experimental treatments: restriction maintenance (RM) where pregnant dams fed at 50% their requirements from 8−84 days gestation, and then feed 100% was supplied 85—parturition (n = 6); (MR) experienced 8). At birth, newborns euthanized samples Longissimus dorsi collected used perform HPLC-MS/MS analysis. The network analyses...
This is an accepted article with a DOI pre-assigned that not yet published.We aimed to assess the impact of vitamin A supplementation in beef cows at late gestation on intramuscular adipogenesis offspring. Thirty pregnant were randomly assigned control group (CONTROL, n = 15) fed diet containing 4.1 KIU per kg, and supplemented (VITA, 12.2 kg. The treatment application occurred from 180 days until parturition. Calves biopsied within 10 age collect skeletal muscle samples for assessing gene...
This study evaluated how nutritional insults applied at different stages of intrauterine development affect the growth and total tract organs mRNA expression genes that encode factors, tight junction proteins, digestive enzymes, glucose transporters in small intestine newborn goats. Fourteen nulliparous dairy goats were assigned to one two plans over gestation: maintenance-restriction (M-R, n = 8) – 100% maintenance requirement from d 8-84 gestation followed by feeding [...]
Vitamin B and trace minerals are crucial molecular signals involved in many biological pathways; however, their bioavailability is compromised high-producing ruminant animals. So far, studies have mainly focused on the effects of these micronutrients animal performance, but use a rumen-protected form impact liver metabolism finishing beef cattle poorly known. We used shotgun proteomic approach combined with network analyses to assess B-vitamin blend, as well those hydroxy minerals, hepatic...
Abstract The increase in marbling deposition without increasing the overall fatness of carcass is one most challenge goals meat industry. Previous studies have suggested nutritional interventions at neonatal stages as a strategy to enhance commitment muscular mesenchymal stem cells adipogenesis, which may contribute finishing phase. As such objective this study was designed evaluate impact nutrient supplementation during pre-weaning stage beef calves has on intramuscular adipogenic...
Abstract The objective of this study was to determine whether supplementing pregnant beef cows with regular nitrogen or a slow-release source at the late gestation could enhance use low protein basal diet and improve performance their offspring until weaning. Thirty-five Brahman (556 ± 47 kg 4.5 1.4 years old) were individually housed in covered pens randomly divided into three groups. From 180 19 days calving, fed either control (CON, n = 12) crude (CP) (6% CP, ad libitum) plus mineral...
