The application high-intensity ultrasound (HIU) in rabbit meat has shown promising results for improving its palatability and commercial value. This study aimed to evaluate the effect of HIU from two breeds (Flemish Giant, FG Azteca Negro, AN) on physicochemical parameters (PQs) sensory profile (SEN). Five carcasses each breed were frozen dorsally cut into half carcasses. was applied (20 min, 50 kHz, 200 W) one randomly selected carcass rabbit. PQs evaluated pH, color (L*, a*, b*), chroma...
Direct and maternal breed effects on birth 200-d weights were estimated for nine parental breeds (Hereford [H], Angus [A], Braunvieh [B], Limousin [L], Charolais [C], Simmental [S], Gelbvieh [G], Red Poll [R], Pinzgauer [P]) that contributed to three composite populations (MARC I = ¼B, ¼C, ¼L, ⅛H, ⅛A; MARC II ¼G, ¼S, ¼H, ¼A; III ¼R, ¼P, ¼A). Records from each population, the plus pure crosses used create composite, analyzed separately. The animal model included fixed of contemporary group...
Dominance and additive × genetic variances were estimated for birth weaning traits of calves from three synthetic lines beef cattle differing in mature size. Data consisted 3,992 2,877 records small-, medium-, large-framed each two research herds located at Rhodes McNay, IA, respectively. Variance components separately by herd line weight (BWT), hip height (BH), 205-d (WW), (WH) derivative-free REML with an animal model. Model 1 included fixed effects year, sex, age dam. Random direct (a)...
The nature of the heterogeneity variance for 200- and 365-d weights by sex, sire breed, dam breed subclasses was studied. Data consisted records weaning (n = 7,829) yearling 7,367) progeny from 673 672 sires, respectively, 22 breeds that have been evaluated in Germ Plasm Evaluation Program at U.S. Meat Animal Research Center, Clay NE. Sires were mated to Hereford Angus cows. Each trait analyzed separately. Three studies undertaken separately investigate due different factors (i.e., or...
Boneless strip loins from mature cows (50 to 70 months of age) were vacuum impregnated (VI) with an isotonic solution (IS) sodium chloride. This study sought determine the impregnation and microstructural properties meat cull cows. The experiments conducted by varying pressure, p 1 (20.3, 71.1 kPa), time, t (0.5, 2.0, 4.0 h), impregnation. After VI step, was kept for a 2 (0.0, 0.5, in IS under atmospheric pressure. changes, impregnation, deformation, porosity measured all treatments....
Two essential oils (EO), thymol and carvacrol, were used in six ratio (100:00, 80:20, 60:40, 40:60, 20:80 00:100) combinations of both EO a dose 0.2 g L-1 bovine ruminal culture medium, 24-h cultures, to evaluate effects on total gas production (TGP), methane production, vitro dry matter digestibility (IVDMD) population dynamics methanogenic bacteria. Total DNA extracted from microorganisms was subjected denaturing gradient gel electrophoresis (DGGE)-polymerase chain reaction (PCR) examine...
Background: Quantitative trait loci (QTL) are genomic regions that influence essential traits in livestock. Understanding QTL distribution and density across species’ genomes is crucial for animal genetics research. Objectives: This study explored the QTLome of cattle, pigs, sheep, chickens by analyzing evaluating correlation between QTL, gene density, chromosome size with aim to identify QTL-enriched regions. Methods: Data from 211,715 (1994–2021) were retrieved AnimalQTLdb analyzed using R...
The draft genome of Citrobacter sp. CtB7.12, isolated from termite gut, is presented here. This organism has been reported as a cellulolytic bacterium, which biotechnologically important because it can be used gene donor for the ethanol and biofuel industries.
Methanogenesis is a metabolic process that allows the rumen ecosystem ability to maintain low hydrogen partial pressures needed for proper digestive function. However, methanogenesis considered be an inefficient because it can result in loss of 4% 12% total energy consumed by host. Recent studies have shown some short-chain nitrocompounds such as nitroethane, 2-nitroethanol, 2-nitro-1-propanol, and 3-nitro-1-propionic acid (3NPA) are capable inhibiting production methane during vitro...
Caracterizar el crecimiento ayuda en la toma de decisiones manejo, comercialización y mejoramiento genético. El objetivo fue identificar un modelo no lineal (MNL) para describir curva borregas registro a través siete razas. Se evaluó peso vivo, desde nacimiento hasta los 230 d edad, las razas Blackbelly (BB; n= 19,084), Pelibuey (PE; 39,025), Dorper (DR; 35,814), Katahdin (KT; 74,154), Suffolk (SF; 10,267), Hampshire (HS; 7561) Rambouillet (RB; 7,384). evaluaron MNL: Brody (BRO), Verhulst...
We investigated whether a panel of molecular markers previously associated with temperament has an effect on live growth traits. Phenotypic data from 412 Charolais cows categorized according to their age in adult and young were used determine Pearson's correlations between birth (BW), weaning (WW), yearling (YW) weight traits (measured as exit velocity [EV] score [TS]). For association analysis, selective genotyping group 80 identified the most docile [...]
Summary The objective of this study was to determine the genetic diversity creole cattle in northwestern Mexico using BoLA-DRB3.2 locus Major Histocompatibility Complex (MHC). A total 56 were sampled from five communities; state Chihuahua (Cerocahui, Guadalupe y Calvo and Cuauhtémoc) Baja California Sur (La Paz Mulegé). genotyped by PCR-RFLP assay. Thirty-nine alleles identified, out which 14 had not been previously reported. average level inbreeding all populations analyzed F IS = 0.09 ( P...
