We report the genetic relationship between growth and bone quality traits in a random mating broiler control population. Traits studied were rates from week 0 to 4 [body weight gain (BWG) 4], 6 (BWG 6), residual feed intake (RFI) 5 (RFI 6). Bone obtained at weeks of age. These shank (SW), length (SL), diameter (SDIAM), tibia (TW), (TL), (TDIAM). Likewise, was used obtain density (TDEN), breaking strength (TBS), mineral (TMD), content (TMC), ash (TAC). At phenotypic level, positively...
Ascites syndrome (AS) is a deadly condition in fast-growing chickens, preceded by pulmonary arterial hypertension (PAH), where the angiotensin II type 1 receptor (ATR1) plays role. We investigated whether allicin (ALLI), garlic derivative, could (a) interact with broiler ATR1, (b) affect ascites-related traits [haematocrit content (Hct%), blood oxygen saturation (SaO
Animal growth is a complex and dynamic process that involves physiological morphological changes from hatching to maturity. It defined as the increase in body size per time unit. Mathematical functions, called models, have been used explain patterns. The aim of this study was compare Gompertz-Laird, logistic, Richards, Von Bertalanffy models determine which best fits data Creole chickens (CC). Three hundred forty-seven CC were individually weighed until 177 D age. Birds fed starter diet...
Improvement in growth has been widely reported as the cause of increased incidence leg problems broiler chickens. We report herein genetic relationship between and a random mating control population. The traits studied were valgus (VL), varus (VR), tibial dyschondroplasia (TD), which expressed on binary scale 0 (normal) 1 (abnormal); rates from to 4 wk (BWG 0-4) 6 age 0-6); residual feed intake 5 (RFI 5-6). A threshold-linear mixed model was employed for joint analysis categorical linear...
Summary This study examined the molecular mechanisms of methionine pathways in meat‐type chickens where birds were provided with a diet deficient from 3 to 5 weeks age. The on then supplemented either D,L‐methionine or D,L‐ HMTBA 7 weeks. control was L‐methionine hatch till We studied mRNA expression adenosyltransferase 1, alpha, beta, 5‐methyltetrahydrofolate‐homocysteine methyltransferase, methyltransferase reductase, betaine‐homocysteine S‐methyltransferase, glycine N‐methyltransferase,...
Litter material and stocking density were evaluated on welfare-related variables productive performance in broilers. Male chicks (n = 744, “Ross 308” strain) raised either tezontle (TEZ...
The dietary requirement for cysteine is not determined in poultry since it an essential amino acid. need expected to be met through the transsulfuration pathway where homocysteine, a precursor of methionine, converted cysteine. Cysteine major component plumage, and degree which involved plumage other keratized proteins are unknown. We randomly assigned chicks control treatment (deficient cysteine) diets 49 d. thickness skin layers, feather follicle length, were measured at days 10, 24, 34,...
En los últimos 13 años, México incremento su población en 16%, superando 131 millones de habitantes 2023, y se espera que siga aumento. Los productos cárnicos mayor consumo el año 2023 país fueron origen avícola, porcina bovina, sumando un total 4,828,868 toneladas. ese mismo año, para dichos hubo una producción nacional 3,789,735 toneladas, por lo importaron 1,299,987 esto sugiere es necesario producir másLa industria acuerdo con la USDA, 2024 estima del 2% carne pollo respecto a reportado...
We herein report the genetic association between leg problems and bone quality traits in a random mating broiler control population. The problem were valgus (VL), varus (VR), tibial dyschondroplasia (TD), that of shank weight (SW), length (SL), diameter (SDIAM), tibia (TW), (TL), (TDIAM), density (TDEN), breaking strength (TBS), mineral (TMD), content (TMC), ash (TAC). A threshold-linear mixed model, implemented via Bayesian approach, was employed for joint analysis traits. Genetic...
El efecto del ayuno ante-mortem en la calidad de carne conejo ha sido poco estudiado. Se utilizaron 180 conejos machos raza Nueva Zelanda Blanca 2,0 kg ± 0,04 peso vivo (PV), los cuales fueron distribuidos cuatro tratamientos (0, 4, 8 y 12 h ayuno). utilizó un diseño completamente al azar, con el sacrificio como covariable. evaluaron las pérdidas rendimiento canal, pH inicial canal final (24 h) carne. En músculo Longissimus dorsi se evaluó color, capacidad retención agua (CRA), cocción...
In chickens, early life exposure to environmental microbes has long-lasting impacts on gastrointestinal (GI) microbiome development and host health growth, via mechanisms that remain uncharacterized. this study, we demonstrated administrating a fecal transplant (FMT) from adults day-of-hatch chicks results in significantly higher body mass of birds decreased residual feed intake (RFI), implying enhanced efficiency, at 6 weeks age. To assess the potential through which FMT affects adult bird...
Cysteine is a nonessential amino acid in poultry nutrition. Poultry diets are deficient cysteine, but the bird's cysteine need met through transsulfuration pathway (TSP) where homocysteine converted to cysteine: process catalyzed by cystathionine β-synthase (CBS) and γ-lyase (CTH). also major component of keratinized protein found feathers, extent which involved feather skin development unknown. We randomly assigned chicks control treatment (control diet plus 100 mg/kg body weight...
En México, las propiedades nutricionales de leguminosas tropicales no se conocen ampliamente. Por tanto, el objetivo del presente estudio fue evaluar valor nutricional Arachis pintoi, Clitoria ternatea, Macroptilium atropurpureum y Stylosanthes guianensis. Se evaluaron, proteína cruda (PC), fibra (FC), extracto etéreo (EE), cenizas (CEN), detergente ácido (FDA), neutro (FDN), lignina (LC), digestibilidad in vitro la materia seca (DIVMS) situ MS (DISMS). Las muestras colectaron en parcelas...
The study aimed to evaluate the productive performance, carcass yield, size of digestive organs and nutrient utilization in Mexican Creole chickens, using four diets with different concentrations metabolizable energy (ME, kcal/kg) crude protein (CP, %).Two hundred thirty-six coming from eight incubation batches, were randomly distributed experimental following ME/CP ratios: 3,000/20, 2,850/19, 2,700/18 2,550/17. Each diet was evaluated 59 birds hatching 12 weeks age. variables feed intake...
The objective of this study was to estimate the good-of-fitness and precision parameters Gompertz-Laird, Logistic, Richards, Von Bertalanffy growth models, using different data collection periods (DCP). Two hundred sixty-two Mexican Creole chicks (116 females 146 males), were individually weighed form following sets for each sex: DCP1 (weights recorded weekly from hatching 63 d, every 2 wk, 133 d age), DCP2 DCP3 third day, 14 DCP4 weekly, age).
