this study was conducted to compare digestibility of wheat straw (ws) by fungi and whole rumen microorganisms (wrm). dry matter (dm), neutral and acid detergent fiber (ndf and adf) digestibility of ws were compared with in vitro digestion (ivd), gas production (gp) and specific rumen anaerobic fungi culture (srafc). dry matter, ndf and adf digestibility of ws by wrm of buffalo (60.80, 49.93 and...

The effect of 3 fermentation methods, in situ (IS) in 4 lactating cows (average pH of 5.8), in vitro (IVn) with media pH of 6.8, or in vitro (IVa) with media pH adjusted to 6.0 using citric acid, on fiber degradation parameters was studied using feeds ground to different particle sizes. Corn silage (CS), grass silage (GS), barley grain (B), sugar beet pulp (BP), and rapeseed cake (RC) were grou...

Four crossbred Sindhi heifers with an average body weight (BW) of 135 kg and a mean age of 17 months were used to investigate the effect of feeding different combinations of rice straw and ensiled water hyacinth (EWH) supplemented with a source of protein in the form of cottonseed cake (CSC) on intake and digestibility. Four treatments consisting of graded levels of EWH were arranged in a 4×4 L...

the aim of this paper was to study of the effect of fenugreek seed (trigonella foenum-graecum) and asparagus root (asparagus officinalis) on in vitro digestibility and kinetics of gas production of alfalfa hay. fenugreek seed (fs) and asparagus root (ar) were added at different levels (0, 5, 10, 15 and 20% of dm). total phenolic components of alfalfa hay (ah), fenugreek seed (fs) and asparagus ...

the objective of this study was to determine the effect of irradiation of pomegranate seed (ps) on chemical composition, digestibility and kinetic of gas production. pomegranate seeds were exposed to gamma ray (gr) and electron beam (eb) at doses of 5, 10, 15 and 20 kgy. three ruminally fistulated rams were used for obtaining ruminal fluid for in vitro digestibility and gas production measuremen...

The key chemical analysis used to estimate the energy value of alfalfa hay for trading purposes, ADF (acid detergent fiber), has been supplanted by NDF (neutral detergent fiber) as the key chemical analysis used by nutritionists to evaluate the fibrosity and energy value of alfalfa hay for nutritional purposes. It is important that the alfalfa hay trading industry abandon ADF, as it will genera...

The aim of this paper was to study of the effect of fenugreek seed (Trigonella foenum-graecum) and asparagus root (Asparagus officinalis) on in vitro digestibility and kinetics of gas production of alfalfa hay. Fenugreek seed (FS) and asparagus root (AR) were added at different levels (0, 5, 10, 15 and 20% of DM). Total phenolic components of alfalfa hay (AH), fenugreek seed (FS) and asparagus ...

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...

An in vitro experiment was conducted to study the effect of non-fiber carbohydrates (NFC) on ruminaldisappearance kinetics of dry matter (DM) and neutral detergent fiber (NDF) of alfalfa hay, wheat bran andunmolassed sugar beet pulp. Non-supplemented or NFC supplemented samples [70 mg/g DM of each feedsample as sucrose (SU) or starch (ST) or SU + ST as 1:1] were incubated in bottles containing ...
