Residual feed intake (RFI) in dairy cattle typically calculated at peak lactation is a measure of efficiency independent milk production level. The objective this study was to evaluate differences ruminal bacteria, biopolymer hydrolyzing enzyme activities, and overall performance between the most- least-efficient cows during peripartal period. Twenty multiparous Holstein with daily ad libitum access total mixed ration from d − 10 60 relative calving date were used. Cows classified into...
Pregnancy and early life are critical periods of plasticity during which the fetus neonate may be influenced by environmental factors such as nutrition. Maternal methionine (Met) supply in non-ruminants pregnancy can affect offspring development growth. Thus, objective this study was to investigate if increasing Met late-pregnancy affects developmental parameters calf at birth either maternal or colostrum from Met-fed cows alters Calves born Holstein individually-fed a basal control [CON;...
Abstract Background Omega-3 PUFA or methionine (Met) supply during gestation alters offspring physiology. However, the effect of both nutrients on fetal development has not been explored. Our objective was to determine effects supplementation these two late growth, DNA methylation, and mRNA expression genes associated with inflammatory response, methylation. Ewes ( n = 5/treatment) were fed from day 100 145 one following treatments: 1) basal diet (NS) without fatty acids (FS) (MS)...
Immune dysfunction and a higher risk of uterine infections are characteristics the transition into lactation in dairy cows. The supply complexed trace minerals, which more bioavailable, could help overcome greater needs these nutrients tissues around parturition early lactation.Twenty Holstein cows received an oral bolus with mix inorganic minerals (INO) or (AAC) to achieve 75, 65, 11, 1 ppm supplemental Zn, Mn, Cu, Co, respectively, total diet dry matter from -30 d through +30 relative...
Main objectives were to determine what extent Smartamine M (SM) supplementation a prepartal higher-energy diet could alter neutrophil (PMN) and liver tissue immunometabolic biomarkers, whether those responses comparable in cows fed lower-energy (CON). Twenty-eight multiparous Holstein CON (NEL = 1.24 Mcal/kg DM) during d −50 −22 relative calving. From −21 calving, randomly assigned (OVE, n 9; NEL 1.54 DM), OVE plus SM (OVE + SM, 10; 0.07 % of or remained on (n 9). All received the same basal...
The peripartum (or transition) period is the most-critical phase in productive life of lactating dairy cows and optimal supply trace minerals through more bioavailable forms could minimize negative effects associated with this phase. Twenty Holstein received a common prepartal diet postpartal diet. Both diets were partially supplemented an inorganic (INO) mix Zn, Mn, Cu to 35, 45, 6 ppm, respectively, dry matter (DM). Cows assigned treatments randomized completed block design, receiving...
Four trials were conducted to evaluate the effects of flint corn processing and replacement with citrus pulp (CiP) in diets for Nellore feedlot cattle. In a 103-d finishing trial, 216 bulls (350 ± 24 kg initial BW) used randomized complete block design 2 × 4 factorial arrangement treatments. Factors included methods, either ground (GC) or steam-flaked (FC), CiP replacing each type at levels (0, 25, 50, 75% DM). All contained 12% sugarcane bagasse 88% concentrate (DM basis). Treatments also...
The concept that fat supplementation impairs total-tract fiber digestibility in ruminants has been widely accepted over the past decades. Nevertheless, recent interest dietary fatty acid profile to dairy cows enlightened possible beneficial impact of specific acids (e.g., palmitic, stearic, and oleic acids) on digestibility. Since are main present ruminal bacterial cells, we hypothesize supply these will favor their incorporation into cell membranes, which support growth enrichment...
Abstract The mechanistic target of rapamycin (mTOR) predominantly regulates the expression and activity placental nutrient transporters. mTOR pathway can be activated by several nutrients, including essential amino acid methionine. Additionally, previous research in nonruminant animals suggests that is influenced a sexually dimorphic manner. In bovine, there limited understanding how maternal nutrition offspring sexual dimorphism affect transfer nutrients. Thus, we investigated effects...
In rodents, fibroblast growth factor 21 (FGF21) has emerged as a key metabolic regulator produced by liver. To gather preliminary data on the potential importance of FGF1, co-regulated genes, and upstream we examined hepatic mRNA expression in response to nutrition inflammation dairy cows. experiment 1, induction ketosis through feed restriction d 5 postpartum upregulated FGF21, its co-receptor KLB, PPARA but only elicited numerical increase serum FGF21 concentration. 2, cows control (CON)...
