This study evaluated how the backgrounding diet can affect water intake, animal performance and feed efficiency of steers fed finishing diets based on grains or forages. Twenty-four crossbred Angus (298 ± 10.2 kg) were during either a moderate (MP, n = 12; triticale hay only, 9.1%crude protein [CP], 1.07 Mcal/kg net energy available for maintenance [NEm], 0.52 gain [NEg]) high plane nutrition (HP, 85% alfalfa 15% beardless wheat hay, 12.62%CP, 1.23 NEm, 0.66 NEg) background phase (85 d)....
The appropriate supply of nutrients in pregnant cows has been associated with the optimal development foetal tissues, performance their progeny and meat quality. aim this study was to evaluate supplementation effects grazing different stages gestation on skeletal muscle progeny. Thereby, 27 Nellore were divided into three groups (n=9 for each group) as follows: UNS, unsupplemented during gestation; MID, supplemented from 30 180 days LATE, 181 281 gestation. percentage composition supplement...
Nutrition is one of the most important factors that affect animal performance, and it therefore also impacts on financial results in beef systems. In this way, finding best strategy for feeding supplements paramount importance. Aiming to evaluate effect supplement strategies cows last third gestation, two experiments were conducted. Experiment 1, 35 pregnant Nellore assigned a completely randomized design with four treatments: control, which received no supplement; supplementation 30 d...
The objective of the present study was to evaluate effect increasing levels prepartum and postpartum protein supplementation on nutrient intake digestibility, productive performance metabolic status beef heifers tropical pasture. Twenty-eight pregnant with bodyweight body condition score 459.7 ± 6.8 kg 5.8 0.10 respectively, were used. experiment performed according a completely randomised design, following four treatments: 0.0, 0.4, 0.8 1.2 kg/animal.day supplement containing 25% crude...
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...
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...
Ruminal tympany (bloat) has long been an issue for large and small livestock operations. Though improvements in feedlot management practices have reduced its occurrence, it is still highly prevalent known to detrimentally affect animal performance, welfare, many instances, lead death. Current decision support systems diet formulation software omit the inclusion of bloat prediction based on performance. Here, we aim predict incidence implanted non-implanted steers from performance data...
This study assessed the effects of different amounts supplement on productive performance, nutrional caracteristics and behaviour suckling beef calves, as well performance their dams tropical pastures. Forty-four male Nellore calves with an average age 120 days initial body weight (BW) 145±3.7 kg respective dams, BW 449±6.9 kg, were used. The evaluated follows: 0 = received only mineral mixture ad libitum; 3, 6, 9 or g kg-1 supplement, respectively, containing 250 CP (as-fed). experimental...
Abstract Aiming to characterize the effects of nutritional status on epigenetic markers, such as DNA 5-methyl cytosine (mC) methylation and RNA N6-methyladenosine (m6A) methylation, bovine sperm, 12 Angus × Hereford crossbred breeding bulls were submitted changes for a period 180 d: no change in body weight (BW) (phase 1 = d), BW loss 2 78 gain 3 90 d) repeated measures design. Animals fed Beardless wheat (Triticum aestivum) hay mineral mix. Statistical analyses performed using SAS 9.4 (SAS...
The aim of this study was to evaluate the effects multiple supplements with different protein sources on performance, intake, nutrient digestibility, and microbial production efficiency lactating beef heifers under grazing. experiment carried out during period transition from water-dry (February July, 2012) using four paddocks average 4.5 ha. Twenty initial body weight 113 kg 3 month old, were used. treatments were: mineral mixed (MM) ad libitum, soybean meal (SM), cottonseed 38% crude (CM),...
Context Few studies have evaluated the effects of providing concentrate pre- or postpartum, during both these intervals, to beef cows grazing tropical pastures, even though this information is important for planning breeder herd management. Aims A study was undertaken examine supplementation with concentrates before calving (prepartum), after (postpartum) intervals on production and reproductive efficiency in Bos indicus Urochloa decumbens pasture. Methods Nellore cows, initially 6 months...
<p>O objetivo do trabalho foi avaliar o efeito fornecimento de diferentes quantidades suplementos múltiplos sobre as características nutricionais e desempenho produtivo novilhas durante a fase recria em pastagens com <em>Urochloa decumbens </em>no período transição seca-águas. Foram utilizadas 24 idade peso médio inicial 11 meses 243±3 kg, respectivamente. O delineamento inteiramente casualizado quatro tratamentos seis repetições. Utilizou-se um suplemento 25% PB. Os...
Abstract Exploring alternative supplementation sources capable of maximizing feed and water efficiency in nursing Holstein calves is often ignored. The goals herein involve investigating the effects two isoenergetic supplements on a nonmedicated milk replacer diet total intake, fresh intake parameters, performance bull calves. Twenty-three animals (body weight [BW] = 94.67 ± 12.07 kg, age 67 days old) were randomly assigned to one three treatments for 68 days: control (CON; ad libitum...
<p>This study was conducted to evaluate the productive and nutritional performance of suckling calves fed only a mineral mix (MM) or different levels multiple supplement milk yield parameters beef cows on <em>Uruchloa decumbens </em>pastures. Thirty-two calves, with an average age 3 months initial weight 109.3 ± 0.84 kg, their respective mothers, 447.2 47.1 were used. The experimental design completely randomized. contained approximately 25% crude protein (CP), treatments...
<p>Objetivou-se avaliar o efeito da substituição do farelo de soja pelo algodão em suplementos múltiplos sobre as características nutricionais e desempenho produtivo novilhas corte fase recria pastagens <em>Brachiaria decumbens </em>no período seca. Foram utilizadas 24 nelore com idade peso médio inicial 8 meses 210±6 kg, respectivamente. O delineamento foi inteiramente casualizado quatro tratamentos seis repetições.
