the nutritive value of grass pea (lathyrus sativus l.) hay was evaluated based on its chemical composition, gas production, fractioning of protein in cncps and afrc systems, metabolizable energy (me), rumen degradability through in situ technique and in vitro digestibility through tilley and terry method. the crude protein (cp), neutral detergent fiber (ndf) and acid detergent fiber (adf) value...

in this research to investigate of the effect of tannin`s type and level on rumenal degradation of soybean meal (sbm) and canola meal (cm), two experiments have be done. at first experiment supplements were treated by semi-pure tannin of pomegranate-pistachio (pp), in different levels (0, 10 and 15 % of dm for sbm and 0, 5 and 10% of dm for cm). in second experiment, these supplements were trea...

Se evaluaron las fracciones de proteína en cuatro genotipos soya: Ojo tigre, Valente, Alvina y Salcer, (generados a partir la variedad ISAAEG – BM2), tres etapas fenológicas: 100% floración, ejote tierno grano. Las muestras se obtuvieron parcelas agrícolas del Centro Estudios Profesionales Colegio Superior Agropecuario Estado Guerrero (CSAEGRO), localizado el Km 14.5 carretera Iguala Cocula, Gr...

The objectives of this study were: (1) To investigate the effects of conditioning temperature (70, 80, 90°C), time (30, 60 sec), and interaction (temperature × time) during the pelleting process on internal protein molecular structure changes of the co-products; (2) To identify differences in protein molecular structures among pellets that were processed under different conditions, and between ...

A goal of animal scientists has been to generate information capable of improving the productivity of farm animals. Historically, improvements in productivity have been achieved by enhancements in performance, i.e. increased rates of growth, lactation, etc. However, maximum performance may not always equate to maximum profit, particularly if one considers environmental costs associated with the...
