Traditional forage nutrient analysis from bench-top near-infrared spectroscopy (NIRS) or common laboratory chemical procedures provides accurate, point-based information, but often does not provide it in a timely way to allow changes in forage or animal management. The objective of this study is to determine the feasibility of estimating concentrations of nitrogen, neutral detergent fiber (NDF)...

This study was carried out to investigate the effects of Yerba Mate (YM) supplementation on nutrients' degradation, in vitro dry matter disappearance, gas production and rumen ammonia concentration. Three rumen-fistulated Holstein Friesian cows were used for the in situ incubations and provided rumen liquor for in vitro incubations. The inclusion of YM in a control diet (pasture+pellets) affect...

The evaluation of foodstuffs provides the animal nutritionists with necessary information to adjust the diet from a physiological and economic point of view, so that the animal performance be desirable. Nowadays, there are various methods for evaluating ruminant feed intake. One of the most important methods is in situ nylon bag technique. Prosopis farcta is one of plants which is used as forag...

The current study evaluated the effects of electron beam (EB; 10, 20, 30 and 40 kGy), urea and NaOH treatments on chemical composition, phenolic compounds, in vitro gas production and i n situ ruminal degradability of pistachio by-product (PB). The EB decreased (p < 0.01) neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL) contents of PB. Treating PB by NaO...

Physical, mechanical, chemical, and thermal properties of sugar palm (Arenga pinnata) fiber were investigated for specimens obtained from three different locations: Kuala Jempol (Peninsular Malaysia), Tawau (West Malaysia), and Tasik Malaya (Indonesia). The morphology of the fiber were observed through scanning electron microscopy (SEM), the thermal properties by thermogravimetric analysis (TGA...

A group of231 alfalfa hay sample results received by a commercial lab over 4 years of hay testing in the San Joaquin Valley of California were examined for the relationship between various lab results. ADF2 and NDF were linearly related in this data set (90% of the variation in NDF is explained by the ADF value = R2). There was a very poor relationship between ADF value and CP (R 2 of 26%), whi...

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...

This study aimed to evaluate cassava genotypes identify the ones with best nutritional values for ruminant diets. Nine were used: Amansa Burro (BGM 549), Aramaris 116), Brasília, Cambadinha (BRS Guaíra), Curvelinha, Engana Ladrão 1269), Trouxinha 1468), BRS Gema de Ovo, and Dourada. A completely randomized block experimental design nine treatments (genotypes) three blocks (replicates) employed....

range forage of vicia variabilis, astragalus spp., medicago sativa, prangos uloptera and sanguisorba minor was sampled during three phenological stages from the controlled rangeland stations in chaharmahal and bakhtiari province, iran. samples were analyzed for the determination of crude protein (cp%), ether extract (ee), crude fiber (cf), total ash, neutral detergent fiber (ndf), acid detergen...

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...
