three artificial neural networks (ann) models; general regression neural network (grnn), redial basis function (rbf) and three layer multiple perceptron network were carried out to evaluate the prediction of the apparent metabolizable energy (ame) of wheat and corn from its chemical composition in broiler. input variables included: gross energy (ge), crude protein (cp), crude fiber (cf), ether ...

the aim of this study was to determine and scrutiny about chemical compounds and microbial load changes of broiler chicks’ diet due to gamma irradiation processing. there were 12 broiler chicks’ diets weighting one kg that including 4 packs from starter period, 4 packs from grower period and 4 packs from finisher period. feeds were irradiated in four doses including 0, 6.7, 7.7 and 8.7 kilogray...

objective: this study carried out to monitor the status of nutritional management and measuring difference between present and desired feeding system in dairy cattle of rural conditions of chaharmahal and bakhtiari. methods: 334 rural flocks consisting of 1442 dairy cows were selected from seven towns of this province. the experiment was lasted for in a year and using completely randomized desi...

The economic return from cereal or cereal/vetch crops was determined using previously published and new agronomic herbage quality data experiments conducted at four sites across southern New South Wales, Australia, over years (2008 to 2011), evaluate the parameters of two wheat (Triticum aestivum L.), barley (Hordeum vulgare oat (Avena sativa one triticale (x Triticosecale) variety, grown as mo...

Racing pigeons are exposed to and act as carriers of diseases. Dietary protein requirement for their maintenance has not been determined experimentally despite their being domesticated for over 7000 years. A maintenance nitrogen (protein) requirement (MNR) for pigeons was determined in a balance study using diets containing 6, 10 and 14% crude protein (CP). Then, the effects of feeding the diet...

Metabolizable protein (MP) supply and amino acid balance were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources. Effects on production efficiency and N utilization of early post-partum dairy cows were determined. Forty-two multiparous and 16 primiparous Holstein cows were assigned to the diets in a randomized complete block design immediately after part...
