Abstract The study evaluated the effect of gender status on carcass and meat quality feedlot Angus × Nellore cattle. A total 176 cattle, 20 months old, were confined for 190‐days assigned to four treatments: bulls, immunocastrated, steers, heifers. Bulls had greater rib eye area HCW ( p = 0.0001). Heifers increased fat thickness Steers heifers higher marbling scores There was interaction between aging time Warner‐Bratzler Shear Force 0.0002), L* 0.0118), b* 0.0113) values beef. sensory panel...
This study was conducted to evaluate the fatty acid profile, sensory properties and lipid oxidation of meat on retail display (RD) from Nellore steers (n = 96) fed diets containing soybean (SOY), sunflower (SUN), or linseed (LIN) oil a control diet (CON). After slaughtering, samples Longissimus muscle were collected for (1 day), composition day) stability (3 days under RDC) evaluations. No differences in total lipids, cholesterol, TBARS, SFAs, MUFAs, PUFAs, PUFA/SFA observed. However,...
The aim of the present study was to estimate covariance components and genetic parameters for beef fatty acid (FA) composition intramuscular fat in longissimus thoracis muscle Nelore bulls finished feedlot. Twenty-two FAs were selected. heritability estimates individual ranged from 0.01 0.35. myristic (0.25 ± 0.09), palmitic (0.18 0.07), oleic (0.28 linoleic (0.16 0.06) α-linolenic (0.35 0.10) moderate. Stearic, elaidic, palmitoleic, vaccenic, conjugated acid, docosahexanoic, eicosatrienoic...
The effects of soybean oil inclusion in a high concentrate diet on performance, carcass traits, meat quality and fatty acid (FA) composition 30 Nellore (NEL) non-castrated crossbred Angus x (AxN) animals were evaluated an 133-d feeding study. Animals assigned randomized complete block (initial body weight) design using 2×2 factorial arrangement. Treatments consisted two genetic groups (NEL AxN) diets: 1) basal containing no (CON) 2) 3.5% (SBO). Performance data obtained during the period....
The objective of this study was to evaluate the effect nutritional management during rearing and finishing phases on beef fatty acid composition, carcass quality traits Hereford cattle. used 240 castrated male calves weaned at 8 months age, with an average weight 170 ± 17 kg. After weaning, experiment divided in three a 4 × 2 factorial design: 93-day winter period four treatment groups (on pasture or feedlot high low feeding levels); 196-day compensatory-growth phase pasture; either feedlot....
Abstract The aim of this study was to evaluate the genomic predictions using single‐step best linear unbiased predictor (ssGBLUP) method based on SNPs and haplotype markers associated with beef fatty acids (FAs) profile in Nelore cattle. data set contained records from 963 bulls finished feedlot (±90 days) slaughtered approximately 24 months age. Meat samples Longissimus dorsi muscle were taken for FAs measurement. quantified by gas chromatography a SP‐2560 capillary column. Animals...
Beef fatty acid profile can be modified by the sex of animals. Therefore, goal this study was to evaluate influence gender status on beef feedlot Angus × Nellore cattle. A total 176 cattle, 20 wk age, from Brazilian Certified Program were assigned 4 classes: 32 bulls, 48 steers, immunocastrates, and heifers, presenting initial mean weights 251.4 ± 3.62 kg for 266.6 2.95 226.4 255.4 heifers. Cattle fed during 190 d an ad libitum high-grain diet containing 80% concentrate. At end experimental...
The use of functional oils replacing additives, such as antibiotics, ionophores, and growth promoters, has shown good results. Furthermore, there is an increasing demand from consumers for healthier meat. Therefore, the aim this study was to evaluate effects inclusion (Ricinus communis Anacardium occidentale) vitamin E in high-grain diets on meat sensory traits lambs. A total 30 crossbred lambs (12 males 18 females), 5 mo age, were used. Lambs presenting initial mean weights 26 ± 3.6 kg...
Different nutritional management during the rearing and finishing periods can determine changes on beef fatty acid profile. Beef lipid composition was quantified in 224 male Hereford calves weaned at 8 wk of age with an average initial live weight (LW) 170 ± 17 kg. After weaning, 4 treatments were imposed to obtain different daily LW gains (LWG; kg/d) first winter. Nutritional groups high LWG feedlot (HF), low (LF), pasture (HP), (LP). The phase began when each group reached a mean 350 28...
The aim of this study was to identify genomic regions associated with the total amount saturated (SFA), monounsaturated (MUFA), and polyunsaturated (PUFA) fatty acids in beef Nellore cattle. investigated dataset contained records from 963 bulls, about two years old, finished feedlot (90 days). Meat samples Longissimus dorsi muscle, between 12th 13th ribs left half-carcasses, were taken measure (FAs). FAs quantified by gas chromatography (GC-2010 Plus - Shimadzu AOC 20i autoinjector) using...
The objective of the present study was to evaluate effect oregano essential oil and black wattle tanniniferous extract in diet feedlot lambs on meat fatty acid composition. At beginning trial, 36 intact male (Dorper × Santa Inês Texel), at approximately 90 d age initial BW 26 kg, were housed individual stalls. allocated into 3 treatments (n = 12) a randomized block design, using as blocking criteria, fed for 60 d. experimental evaluated 1) Control diet, 2) with inclusion (1 mL/kg...
Many studies have demonstrated the damaging effect of gases such as ammonia in production broilers chickens, especially on performance and blood parameters. However, few evaluated using additives to treat poultry litter chicken meat quality. Therefore, goal this study was evaluate effects aluminum sulfate doses (Al2(SO4)3·18H2O; 0, 200, 400, 600 g/m2) stocking density (12 14 birds/m2) quality traits. A total 532 broiler male Cobb 500 chicks presenting an initial mean weight 46 g ± 2.3 were...
