Physically effective fiber is needed by dairy cattle to prevent ruminal acidosis. This study aimed to examine the effects of different sources of physically effective fiber on the populations of fibrolytic bacteria and methanogens. Five ruminally cannulated Holstein cows were each fed five diets differing in physically effective fiber sources over 15 weeks (21 days/period) in a Latin Square des...

introduction ensiling is less dependent to weather condition and farmers are trying to ensile forages for preserving them for livestock feeding. ensiling legumes because of their buffering capacity and high moisture content are difficult. also, ensiling alfalfa will lose up to %85 of its nitrogen content as non-protein nitrogen. adding some additives like carbohydrate sources will improve alfal...

In this experiment, we evaluated the influence of increasing chop length and mechanical processing of whole-plant brown-midrib corn silage on intake, digestion, and milk production by dairy cows. Corn silage treatments were harvested at three-quarter milk line stage of maturity at 13- and 19-mm theoretical chop length without processing, or at 19- and 32-mm theoretical chop length with processi...

Particle size alterations during neutral detergent fiber (NDF) determination and in situ rumen incubation were analyzed by dry sieving and image analysis to evaluate the in situ procedure for estimation of NDF degradation parameters and indigestible NDF concentration in terms of particle size. Early-cut and late-cut grass silages, corn silage, alfalfa silage, rapeseed meal, and dried distillers...

This study was carried out in the central county of Ağrı Province order to reveal cattle feeding habits breeders. For this purpose, data were obtained by conducting a face-to-face survey with 400 dairy owners enterprises county. According results from study, it determined that 91.5% breeders produced their forage crops. It also found barley, alfalfa, and sainfoin most plants these enterprises. ...

Five trials were conducted to develop a system to estimate rumen-undegradable protein (RUP) of legume and grass silages using near infrared reflectance spectroscopy. In situ procedures were the reference method used to determine silage RUP content. Trials 1, 2, and 3 were devoted to improving in situ procedures. In trial 1, alfalfa silage with and without heat treatment was incubated ruminally ...

The purpose of this study was to examine the effects fermentation parameters on addition clove oil oat straw, alfalfa hay, and maize silage at a 3% dry matter basis. In vitro gas production, methane production (CH4), metabolic energy (ME), net lactation (NEL), organic digestion (OMD) were all influenced by (P
