The brown midrib-3 (bm3) gene mutation has been incorporated into corn plants to potentially improve fiber digestibility. The objectives of this study were to determine the effect of bm3 corn silage on digestion and performance of growing beef steers and to determine whether limiting intake would further enhance fiber digestibility of bm3 corn silage. A bm3 hybrid and its isogeneic normal count...

Three trials were conducted to determine the available energy of different wheat screening varieties collected from different locations of Khorasan in Iran. In experiment 1, chemical composition and the nitrogen corrected true metabolisable energy (TMEn) were evaluated. A precision-fed rooster assay was used, in which, each wheat screening sample was tube fed to adult roosters, and the excreta ...

Three experiments were conducted to measure energy and nutrient digestibility in dried distillers grain with solubles (DDGS) by growing pigs. In Exp. 1, apparent (AID) and standardized (SID) ileal digestibility coefficients of CP and amino acids (AA) were determined in four samples of DDGS using growing pigs equipped with a T-cannula in the distal ileum. Exp. 2 was an energy balance experiment ...

Feeding trials were conducted with 428 forages in three forage classes (C a grasses, legumes, C 4 grasses) fed ad l ibi tum to sheep and with 170 forages fed to cattle over a 20-yr period. Of this total, 153 forages were fed concurrently to sheep and cattle. Where the same forages were fed, mean dry matter digestibility (DMD) and dry matter intake (DMI) were lower (P < .01) for sheep than for c...

The aim of study was to determine ligno-cellulose quality and calorific value cup plant Silphium perfoliatum L., whereas impact nutrition, years sites on the were evaluated as main effects within a huge pilot field experiment. Two complete data sets acid-detergent fiber (ADF), lignin (ADL), crude cellulose (CE), hemicellulose (HEM), neutral-detergent (NDF) high heating (HHV) evaluated, primary ...

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...

Four ruminally and duodenally cannulated steers (703.4 +/- 41 kg initial BW) were used in a 4 x 4 Latin square to evaluate the effects of field pea inclusion level on intake and site of digestion in beef steers fed medium-concentrate diets. Steers were offered feed ad libitum at 0700 and 1900 daily and were allowed free access to water. Diets consisted of 45% grass hay and 55% by-products based...

Two incubation runs were carried out with a Rusitec system to investigate the effects of 2 exogenous pure cellulases on ruminal microbial growth and fermentation of a 70:30 grass hay:concentrate (DM basis) substrate. The substrate was sprayed with buffer (control; pH = 6.5), a cellulase from Trichoderma longibrachiatum (TRI), a cellulase from Aspergillus niger (ASP), or a 1:1 mixture of both ce...

Anavatanı Hindistan olan maş fasulyesi türü, uzun yıllardan beri ülkemizde insan beslenmesinde kullanmak amacıyla yetiştirilmektedir. Bu araştırmada yetiştiriciliği yapılan yerel genotiplerinin ve yurt dışından temin edilen tescilli çeşitlerin tohum hasadı yapıldıktan sonra kalan kısımlarının yem olarak kullanılabilme potansiyelinin belirlenmesi amaçlanmıştır. Çalışma, Isparta Uygulamalı Biliml...

Bu çalışma, 2016-17 ve 2017-18 üretim sezonlarında Tesadüf Blokları Deneme Deseninde dört tekerrürlü olarak Edirne’de yürütülmüştür. 15 yulaf genotipin kullanıldığı denemede, 5 standart çeşit (Kırklar, Kahraman, Kuçukyayla, Yeniceri Sebat) yer almıştır. Araştırmada, genotiplerin yeşil ot kuru verimi ile bazı kalite özellikleri incelenerek hayvan beslemesi için bölgeye uygun belirlenmesi amaçlan...
