This work aimed to determine and compare the effect of elevation season on productivity nutritive value pastures in Azores (Terceira Island). Forage was collected analysed for dry matter (DM), crude protein (CP), neutral detergent fibre (NDF), acid (ADF), lignin (ADL), ether extract (EE), mineral ash (Ash), digestibility (DMD) organic (OMD). The net (NP) higher low pasture A (1.80 g m?2), lower...

The potential of Near Infrared Reflectance Spectroscopy (NIRS) as a fast method to predict the Crude Protein (CP) and Moisture (M) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on Partial Least Squares (PLS) was evaluated. The coefficient of determination in calibration (R2C) and Standard Error of Calibra...

The effects of dietary protein content on the rates of gain and protein deposition were studied in Iberian (IB) × Duroc (DU) 50:50 barrows at 2 stages of growth [10.6 ± 0.2 (n = 28) and 60.0 ± 0.4 (n = 24) kg initial BW]. Two feeding, digestibility, and N-balance trials were performed. At each stage of growth, they were allocated in individual pens and given restrictedly (at 0.9 × ad libitum in...

The aim of this study was to determine the chemical composition of eight invertebrate species and evaluate their suitability as alternative prey. The species selected were rusty red cockroaches (Blatta lateralis), six-spotted cockroaches (Eublaberus distanti), Madagascar hissing cockroaches (Gromphadorhina portentosa), fruit flies (Drosophila melanogaster), false katydids (Microcentrum rhombifo...

A silage inoculant [Biomin® BioStabil Plus, BSP, a blend of Enterococcus faecium (DSM 3530), Lactobacillus brevis (DSM 19456) and Lactobacillus plantarum (DSM 19457)], was used on legume-grass silage [32% of dry matter (DM)] vs. an untreated control silage (CT). The material had mean crude protein (CP) and water soluble carbohydrate (WSC) concentrations of 174 and 88 g/kg,respectively. BSP resu...

nutritive value of ephedra (ephedra intermedia) was evaluated through determination of chemical compositions, in situ degradability and in vitro gas production techniques using three permanently fistulated adult baluchi sheep. the samples were harvested during the late spring from rangeland in north of khorasan razavi province. the rate of gas production and degradability characteristics of dry...

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...

introduction: demands of agricultural products, particularly in developing countries, are increasing rapidly. consequently, land and water resources are unable to sustain such demands. for decades, rangelands in africa, west and central asia suffered from overgrazing and many areas are severely degraded. range vegetation used to be the main feed resource for livestock particularly in the arid a...

In this study we investigated the effect of maturity stage on chemical composition, in vitro dry matter digestibility (IVD) and volume of gas produced at 24 h (G24) of forages from Avena sativa L. (oats), Trifolium alexandrinum (berseem), Vicia sativa L. (vetch), Avena sativa-Vicia sativa (OV) and Avena sativaTrifolium alexandrinum (OB) mixtures collected at progressive morphological stages (S1...
