Meat from Bos taurus and indicus breeds are an important source of nutrients for humans intramuscular fat (IMF) influences its flavor, nutritional value impacts human health. Human consumption that contains high levels monounsaturated fatty acids (MUFA) can reduce the concentration undesirable cholesterol (LDL) in circulating blood. Different feeding practices genetic variation within between amount IMF acid (FA) composition meat. However, it is difficult costly to determine composition,...
Efficiency of feed utilization is important for animal production because it can reduce greenhouse gas emissions and improve industry profitability. However, the genetic basis in livestock remains poorly understood. Recent developments molecular genetics, such as platforms genome-wide genotyping sequencing, provide an opportunity to identify genes pathways that influence traits. It known transcriptional networks efficiency-related traits growth energy balance. This study sought...
Intramuscular fat (IMF) content is related to insulin resistance, which an important prediction factor for disorders, such as cardiovascular disease, obesity and type 2 diabetes in human. At the same time, it economically trait, influences sensorial nutritional value of meat. The deposition IMF influenced by many factors sex, age, nutrition, genetics. In this study Nellore steers (Bos taurus indicus subspecies) were used better understand molecular mechanisms involved content. This was...
Feed efficiency is jointly determined by productivity and feed requirements, both of which are economically relevant traits in beef cattle production systems. The objective this study was to identify genes/QTLs associated with components Nelore using Illumina BovineHD BeadChip (770 k SNP) genotypes from 593 steers. analyzed included: average daily gain (ADG), dry matter intake (DMI), feed-conversion ratio (FCR), (FE), residual (RFI), maintenance (ME), (EG), partial growth (PEG) relative rate...
Lipids are a class of molecules that play an important role in cellular structure and metabolism all cell types. In the last few decades, it has been reported long-chain fatty acids (FAs) involved several biological functions from transcriptional regulation to physiological processes. Several have both positively negatively implicated different processes skeletal muscle other tissues. To gain insight into associated with acid content muscle, aim present study was identify differentially...
We used chemical composition and in vitro digestibility data from temperate tropical forages to develop relationships between indices of lignification forage indigestible NDF. Neutral detergent fiber indigestibility increased nonlinearly as the lignin concentration NDF increased. Differences estimated using equations developed for a specific class (C3 C4 grasses legumes) were small are probably not biologically significant when compared those common equation. Selected with Cornell Net...
The objective of this study was to evaluate the effects dietary addition ground oilseed sources on quality, fatty acid profile, and CLA content meat from zebu steers. Thirty-one steers with an initial average age 23 mo BW 365 kg were used in study. experimental period 84 d, which preceded by adaption 28 d. diet provided ad libitum a forage:concentrate ratio 40:60. Corn silage as forage source. Four different concentrates formulated for each treatment: without additional lipids (control) or...
Data from three comparative slaughter experiments with individually fed Nellore bulls (n = 31) and steers 66) were utilized to determine their NEm NEg requirements when high-forage diets. The experimental design provided ranges in ME intake, BW, ADG for the development of regression equations predict requirements. (Trial 1) divided into two intake levels (ad libitum 65% ad libitum). (Trials 2 3) allocated 55 70% In both trials, there groups within each level. end points different days on...
Despite the health concerns and nutritional importance of fatty acids, there is a relative paucity studies in literature that report genetic or genomic parameters, especially case sheep populations. To investigate architecture acid composition sheep, we conducted genome-wide association (GWAS) estimated heritabilities for profile Longissimus dorsi muscle 216 male sheep. Genomic heritability estimates content ranged from 0.25 to 0.46, indicating substantial variation exists evaluated traits....
Nelore is the major beef cattle breed in Brazil with more than 130 million heads. Genome-wide association studies (GWAS) are often used to associate markers and genomic regions growth meat quality traits that can be assist selection programs. An alternative methodology traditional GWAS involves construction of gene network interactions, derived from results several AWM (Association Weight Matrices)/PCIT (Partial Correlation Information Theory). With aim evaluating genetic architecture...
No information regarding the management of manure from beef cattle feedlots is available for Brazil. To fill this knowledge gap, a survey 73 was conducted in 7 Brazilian states. In survey, questions were asked animal characteristics, their diets, and handling generation to disposal. These finished 831,450 animals 2010. The predominant breed fed Nellore, with average feeding periods 60 135 d. Corn primary source grain used feedlot diets (76% surveyed animals) concentrate inclusion levels...
This study aimed to establish the optimum level of palm kernel meal in diet Santa Inês lambs based on sensorial characteristics and fatty acid profile meat.We used 32 with a starting age 4 6 months mean weight 22 ±2.75 kg, kept individual stalls.The animals were fed Tifton-85 hay concentrate mixed 0.0, 6.5, 13.0 or 19.5% dry mass complete diet.These levels formed treatments.Confinement lasted 80 days last day fasted slaughtered.After slaughter, carcasses weighed sectioned longitudinally,...
The objective was to evaluate the fatty acid profile and qualitative characteristics of meat from young bulls fed crude glycerin. Forty-four animals with an initial live weight 368 ± 4 kg were used in a completely randomized design, four treatments: no glycerin or addition 6, 12 18% slaughtered 519.5 14.9 weight. assessed chemical composition, shear force, concentration, color lipid oxidation. increased content ether extract (P<0.05) muscle. A linear increase observed oleic contents (C18:1...
This study was conducted to evaluate the effects of flint corn processing method (CPM) and level NDF from roughage (rNDF) on performance, carcass characteristics, starch utilization by finishing Nellore-based cattle fed high-concentrate, corn–based diets. In this study, 112 Nellore type bulls (initial BW 384.07 ± 29.53 kg 24–36 mo age) were individually using Calan gates or individual pens. The animals used in a randomized complete block design 2 × 4 factorial arrangement with CPM,...
Ensiling corn for longer periods is a strategy used to increase rumen bacteria access starch. In fact, when ensiled insufficient periods, starch digestibility decreases, as evidenced by excreted This study investigates the effects of silage ensiling time on dairy cows through fecal analysis. The trial was conducted during spring 2013 and fall 2014 twenty herds located in state Paraná, southern Brazil. Total mixed ration (TMR), whole-plant (WPCS) samples were collected determination dry...
The Cornell Net Carbohydrate and Protein System (CNCPS) model has been increasingly used in tropical regions for dairy beef production. However, the lack of appropriate characterization feeds restricted its application. objective this study was to develop evaluate a feed library containing commonly with characteristics needed as inputs CNCPS. Feed composition data collected from laboratory databases experiments published scientific journals were library. total digestible nutrients (TDN)...

The effect of bST on the metabolism lipid in adipose tissue was studied using biopsies from lactating cows treated with for 8 d. Cows responded to treatment by increasing daily milk yield 10.9 kg, although net energy intake not changed. Thus, balance changed highly positive slightly negative (+7.7 -1.1 Mcal/d). Consistent these changes balance, lipogenesis rates were dramatically reduced (97%) bST-treated cows. Activities acetyl-coenzyme A carboxylase (initial and total) fatty acid synthase...
Zebu cattle fed high concentrate diets may present inconsistent performance due to the occurrence of metabolic disorders, like acidosis. The isolated use ionophores and virginiamycin in grain can improve animal reduce incidence such but recent studies suggested that their combination have an additive effect. Thus, 72 Nellore steers, 389 ± 15 kg initial body weight (BW), were confined for 79 days evaluate salinomycin on carcass traits. Animals allocated a randomized complete block design by...
