One-day-old broiler chicks (n = 300) were orally vaccinated (Coccivac-B) and divided into 6 groups to evaluate Arg at 3 levels of supplementation, 0, 0.3, or 0.6% [normal level (NARG), medium (MARG), high (HARG), respectively], 2 vitamin E (VE), 40 80 IU/kg feed (VE40 VE80, respectively), in a factorial experiment. Birds reared floor pens with fresh pine shavings provided corn-soybean-based diet water ad libitum. At d 14, all chickens challenged mixture Eimeria field isolates (Eimeria...
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
Barley in Mexico is an important crop for the brewing industry and animal feed. The physical physiological quality vigor of a batch seed cv. Brennus was evaluated. divided by size (small large) with 2.5 mm sieve subjected to different conditioning (aging non-aging). study variables were purity (SP), thousand weight (P1000S), volumetric (PV), moisture content (H), germination percentage, emergence speed, plumule length, dry matter seedling index. analysis variance performed under completely...
The antioxidant effect of oregano essential oil and vitamin E was evaluated in cooked chicken breast meat. In total, 480 broilers were randomly assigned to 6 treatments 4 replications. Broilers raised with a corn-soybean meal diet including either crude soybean or acidulated soapstock, each supplemented at 10 100 mg mg/kg feed. At 42 d, slaughtered their meat prepared into strips (1.5 × cm) patties (150 g). Fatty acid composition the muscle determined. For lipid oxidation stability, both an...
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...
Lameness or leg weakness is becoming an important problem in broilers selected for rapid growth, and although the causes are not known, sedentary behavior could be a cause. Two experiments were conducted to study effects of distance presence ramps between resources (feed water) on bone tendon strength, ability stand, productive performance. In experiment 1, straight run Ross 708 chicks (n = 1,260) randomly assigned 1 3 treatments: 1.0, 3.3, 6.6 m (6 pen replicates/treatment). 2, Cobb 500...
The oxidation of fatty acids decreases the quality and shelf-life meats. To reduce this process, dietary supplemented meat-added antioxidants were evaluated on lipid oxidative stability cooked chicken meat. Broilers fed 2 levels vitamin E (10 or 100 mg·kg−1 feed; VE-10 VE-100, respectively) oregano essential oil (100 OR-100). Additionally, honey (3%) butylated hydroxytoluene (0.02%; BHT) added to meat from control treatment (VE-10). Breast was ground, formed into patties, electric grills...
Abstract Objectives This article aims to study differences in the bone formation and graft resorption of two substitutes ( BGS ). Besides, it is our attempt observe possible qualitative quantitative reparation outer layer covered by collagen membrane uncovered inner close contact with dura mater. Material methods Twelve rabbits were employed. Deproteinized bovine DBB ) β‐tricalcium phosphate BTCP used as . Four subcritical round defects (7 mm) drilled cranial vault, removing both cortical...
Calcium is important in eggshell formation; inadequate levels the diet of laying hens may affect shell quality and egg production. An experiment with 250 Leghorn Hy-Line W-98 was conducted to evaluate 5 dietary Ca (2.96, 3.22, 3.83, 4.31, 4.82%) 3 periods. The evaluated variables were production (EP), mass (EM), average daily feed intake (ADFI), conversion (FC), specific gravity (SG). biological optimum level (BOL) for maximum gravity, economic (EOL) maximize profits calculated. There no...

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...
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...
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...
This study tested whether the intravenous application of kisspeptin can stimulate pulsatile secretion LH in suckling ewes during postpartum anestrus. Ten days after lambing, Pelibuey were allocated among two groups: (1) continuous (n = 8), where lambs remained with their mothers; and (2) restricted mothers suckled twice daily for 30 min. On Day 19 postpartum, individually penned ad libitum access to water feed given an indwelling catheter each jugular vein. 20, 4 mL blood was sampled every...
