The study was aimed to evaluate the reliability and concordance of Schaeffer Agarwal formulae for predicting body weight in Gyr (Holstein×Cebu) crossbred cows heifers. Body (BW), heart girth (HG) length (BL) were recorded 156 98 There a strong positive correlation (p < 0.0001) between BW observed predicted using (r ≥ 0.96 ≤ 0.97). Although agreement low, as indicated by CCC values, they higher formula. results suggest that predictions formula are preferable those Agarwal's may be useful...
El déficit de forrajes tropicales en la temporada seca requiere estrategias alimentación alternas que involucren trasferencia tecnologías y conservación alimentos locales. objetivo fue evaluar respuesta animal el costo beneficio ante raciones mixtas con diferentes niveles inclusión ensilado maíz sistemas producción doble propósito del sur Quintana Roo. Se utilizaron nueve vacas lactantes 152 días leche un diseño experimental cuadrado latino 3 x por triplicado. Las secuencias tratamiento fueron...
ABSTRACT The objective of this study was to develop and evaluate linear, quadratic, allometric models predict live weight (LW) using the body volume formula (BV) in crossbred heifers raised southeastern Mexico. LW (426.25±117.49kg) BV (338.05±95.38 dm3) were measured 360 aged between 3 30 months. Linear non-linear regression used construct prediction models. goodness-of-fit evaluated Akaike Information Criterion (AIC), Bayesian (BIC), coefficient determination (R2), mean squared error (MSE),...
<p><strong>Background</strong>: The use of <em>Tithonia diversifolia</em> foliage can improve the quality animal feed because its crude protein content doubles that tropical grasses. However, plant response regarding biomass production to frequent harvest disturbances are not known well. <strong>Objective</strong>: To evaluate effect different cutting heights and repeated harvests on nutrient <em>T. in fodder banks under warm sub-humid climate....
El objetivo de este estudio fue documentar la percepción estudiantes, con respecto a elaboración y consumo productos agroalimentarios locales en el Municipio Toluca, Estado México, bajo un enfoque sustentabilidad. Se aplicó cuestionario línea estudiantes entre 11 25 años edad. Los resultados fueron capturados hoja Excel analizados través estadística descriptiva. encuestaron 96 57% los encuestados consideraron que consumen afectan su salud. 49% siembra para sus hogares 14% cría animales...
The objective of the study was to evaluate effect different levels maize silage on feed utilization efficiency and nitrogen (N) balance in dual-purpose cows during dry season. Nine crossbred with live weight 423±12 kg were used. treatments were: T1= 2 DM + 3.9 sorghum stubble; T2= 4 1.8 T3= 6 silage. Additionally, all consumed Panicum maximum cv. Mombasa grass, supplemented poultry manure commercial concentrate doses 2.0, 2.9 2.3 DM, respectively. Data comparison performed by ANOVA,...
<p><strong>Background:</strong> Nitrogen (N) plays an important role within milk production systems (MPS), as indicator of environmental and economic efficiency. <strong>Objective. </strong>The objective was to determine utilisation N offered in the ration estimate GHG from enteric fermentation manure management 12 small-scale dairy farms under two feeding strategies. <strong>Methodology.</strong> Six had their herds confinement a cut-and-carry...
The objective of this research was to evaluate and compare the yieldperformance quality Tithonia diversifolia forage under different harvesting heights, during dry rainy seasons in tropical Mexico. treatments consisted three harvest heights 40, 60 80 cm from ground level, cut every60 days, two year. In each period, biomass harvested separated into edible non-edible components. We determined yield, concentration crude protein (CP), neutral detergent fibre (NDF), acid (ADF), lignin, ash...
