The wet chemical analysis of feed samples is time consuming and expensive. Near infrared spectroscopy (NIRS) was developed as a rapid technique to predict the chemical composition of feeds. The prediction of accuracy of NIRS relies heavily on obtaining a calibration set which represents the variation in the main population, accurate laboratory analyses and the application of the best mathematic...

Cultivated forage species may have higher nutrients contents (NC) and quality indicators (FQI) than their wild relatives. Nine samples collected five times from a mixed rangeland an experimental field during two consecutive years was analysed for ash, crude protein (CP), ether extract (EE) neutral detergent (NDF) acid (ADF) fibres. Then, FQI such as digestible dry matter (DDM), intake (DMI), me...

Bahan pakan ternak dengan profil nutrisi yang baik sangat dibutuhkan seiring perkembangan zaman, salah satu bahan potensi besar yaitu biji rami. Penelitian ini bertujuan mengetahui pengaruh lama pemanasan autoklaf terhadap komposisi kimia rami sebagai ayam pedaging. menggunakan Rancangan Acak Lengkap (RAL) 4 perlakuan yaitu: P0 (tanpa autoklaf), P1 (pemanasan 5 menit), P2 10 dan P3 15 menit). V...

the objectives of this study were to determine and compare the chemical composition and ruminal degradability of dry matter (dm), crude protein (cp), neutral detergent fiber (ndf) and acid detergent fiber (adf) of ten pasture forage species dominant in the west provinces of iran. duplicate nylon bags of pasture samples were suspended in the rumen of four wethers for up to 96 h. the chemical com...

Negative interactions of the acidity and S content of dried distillers grains with solubles (DDGS) have not been quantified. The objectives of this study were to determine the effects of dietary S, dietary acidity, and their interactions on growth, feed efficiency, ruminal H2S concentration, and apparent nutrient digestibility in lambs fed DDGS-based diets. To neutralize acidity, the DDGS was u...

Fenugreek (Trigonella foenum-graecum L.) is used as medicinal plant in many Asian countries and has been reported to have forage quality similar to alfalfa. Fenugreek is an annual crop and may have the potential to diversify forage production systems in the central High Plains. This study evaluated forage dry matter (DM) production and the nutritive value of three fenugreek cultivars as influen...

The objective of this work was to measure the apparent ileal digestibility (AID) and the apparent total tract digestibility (ATTD) of dietary fiber in different sources of distillers dried grains with solubles (DDGS) and to calculate hindgut fermentation of dietary fiber in DDGS fed to growing pigs. Diets, ileal digesta, and fecal samples from pigs fed corn or diets containing 1 of 28 sources o...

Seasonal changes in chemical composition represented by crude protein (CP), In vitro true digestibility (IVTD), and fibre components measured neutral detergent (NDF), acid-detergent (ADF) lignin were evaluated at specified cano­py ages stages of maturity Tridax procumb ens. Samples selected from five harvest dates April, June, August, October, December. Chemical com­position was: highly respons...

Understanding forage quality and the factors that affect its constituents will help improve livestock production by making decisions that optimize forage nutritive value and intake. This investigation was conducted in Zagros semi-arid rangeland center, Iran to determine forage quality of several grass and legume species. Samples were collected at early bloom, from 5 m long and 0.10 m wide strip...

This research was conducted to determine the effect of corn genetics and cutting height on the composition and nutritive characteristics of corn silage. An in situ study involving eight commercially available corn hybrids indicated main effects and interactions (P < 0.01) of hybrid and cutting height on NDF, ADF, and starch content and on in situ DM and NDF degradablility. Four ruminally cannul...
