Introducing forage in dairy calf diets during the preweaning period stimulates development of rumen capacity and function gut wall integrity. It was hypothesized that calves fed alfalfa hay (AH) at greater levels (up to 25% DM) would result an increase starter diet intake growth performance. The objective this study determine effects increasing supplemental AH on performance, fermentation, blood metabolites, feeding behavior intact male calves. For purpose, 45 Holstein (3 d age 41 ± 2.5 kg...
Introducing forage in the young calf diet during milk-feeding period stimulates rumen development. It was hypothesized that performance dairy calves would depend on provision and starter physical form such textured (TS) feed with corn silage (CS) supplementation benefit performance. This study evaluates effects of diets CS performance, fermentation characteristics, structural growth calves. Forty-eight 3-d-old Holstein a mean starting BW 42.1 kg (SD 2.4) were used 2 × factorial arrangement...
Abstract Early supplementation with oregano essential oil (EO) in milk replacer (MR) may improve growth, immune responses, the microbiota and metabolome dairy calves during pre-weaning adulthood. Sixteen female (3 days of age) were divided two groups ( n = 8/group): control group (no EO) EO (0.23 ml MR 45 days). After weaning, kept a feedlot fed ad libitum . The animals weighed, blood faecal samples collected on 3 (T0), (T1) 370 (T2) to measure biochemical profile characterise peripheral...
Extracellular vesicles (EV) are membranous considered as significant players in cell-to-cell communication. Milk provides adequate nutrition, transfers immunity, and promotes neonatal development, milk EV suggested to play a crucial role these processes. samples were obtained on days 0, 7, 14 after parturition from sows receiving either standard diet (ω-6:ω-3 = 13:1) or test enriched ω-3 4:1). isolated using ultracentrifugation coupled with size exclusion chromatography, characterized by...
Approximately half of prostate cancers (PCa) carry TMPRSS2-ERG translocations; however, the clinical impact this genomic alteration remains enigmatic. Expression v-ets erythroblastosis virus E26 oncogene like (avian) gene (ERG) promotes prostatic epithelial dysplasia in transgenic mice and acquisition epithelial-to-mesenchymal transition (EMT) characteristics human cells (PrECs). To explore whether ERG-induced EMT PrECs was associated with therapeutically targetable transformation...
The objective of the current study was to examine whether step-down (STP) milk feeding method together with forage provision would improve performance, rumen fermentation, nutrient digestibility, blood metabolites, and structural growth calves. Holstein bull calves (n = 40) were randomly assigned 1 4 treatments in a completely randomized design 2 × factorial arrangement. Treatments 1) conventional (COV) without (COV-NF), 2) COV provision, 3) STP 4) provision. Calves 20) received 5.5 L/d...
The objective of this study was to investigate the effects milk allowances equal 526 g/d as moderate (MOD) versus 790 dry matter high (HI), and starter diets containing 18% or 23% crude protein (CP), on growth performance, blood metabolites, purine derivative (PD) excretion in urine dairy calves. A total 52 female Holstein calves (40.8 kg body weight) were randomly assigned experimental diets. treatments (1) CP diet (MOD-18CP); (2) MOD (MOD-23CP); (3) (HI-18CP); (4) HI (HI-23CP). Calves had...
A deeper understanding of the risk factors for dystocia and stillbirth could help farmers make decisions about dairy cow management. The objectives this study were to investigate cow-level associated with in a relatively large sample cows using multivariable linear regression models. data consisted 51,405 calving records 14,546 Holstein from 3 herds Isfahan Province, Iran, collected between April 2011 September 2017. To association selected blood macro-minerals incidence stillbirth, samples...
Fat composition in milk replacers (MR) for calves differs from bovine fat multiple ways. The aim of the study was to investigate impact different approaches formulating MR on growth, ad libitum intakes and solid feeds, as well blood metabolites dairy calves. Upon 24 96 h after birth, 63 were acquired farms incorporated into study. Calves blocked based arrival day randomly assigned within each block one 3 treatments differing (n = 21 per group): VG vegetable fats including 80% rapeseed 20%...
We investigated the effect of Cr supplementation on growth performance, feeding behavior, health status, and blood metabolites summer-exposed dairy calves during pre- postweaning periods. A total 24 newborn Holstein female (1 d age; 42.1 ± 0.89 kg body weight) were assigned randomly to a control group (no supplement; Cr−) or (Cr+) receiving 0.05 mg Cr/kg weight0.75. During study period, average maximum temperature-humidity index was 81.3 units, indicating high environmental heat load....
Dairy calves may benefit from extending the duration of feeding transition milk (TM; subsequent two to six milkings after parturition) enhance performance and health during early life. The objective this study was assess effect replacing pasteurized waste (non-saleable containing antibiotic and/or drug residues) with TM for 3 weeks on growth dairy calves. A total 84 healthy newborn female Holstein were blocked by birth order assigned randomly 4 treatment groups partial replacement (second at...
This experiment was designed to investigate the effects of feeding diets with different fiber content and forage particle size on performance, health, nutrient digestion, rumen fermentation, behavioral sorting activity Holstein dairy calves kept under elevated environmental temperature. Sixty weaned female (age = 96.7 ± 7.62 days old; body weight 82.4 10.4 kg) were randomly assigned one 4 treatments arranged in a 2-by-2 factorial design 70-day experiment. Dietary (moderate, 22.5%; or high,...
The objective of this study was to investigate the effects pistachio by-products (PBP) in replacement alfalfa hay (AH) on ruminal fermentation, blood metabolites, and milk fatty acid composition Saanen dairy goats fed a diet containing fish oil. For purpose, 15 multiparous lactating (on day 25 postpartum, 38.15±1.2 kg) were randomly assigned three treatment diets completely randomized design with five per treatment. consisted feeding following diets: (1) control (AH), (2) 30% PBP, (3) PBP +...
The goals of ruminant protein nutrition are to provide adequate amounts RDP for optimal ruminal efficiency and obtain the desired animal productivity with a minimum amount dietary CP. aim present study was examine effects decreasing by optimum concentration RUP on production performance, nutrient digestibility, N retention, rumen fermentation parameters, blood metabolites in high-producing Holstein cows early lactation. Nine multiparous lactating (second parities, averaging 50 ± 12 d milk...
