The objectives of this study were to determine whether Propionibacterium affects in-vitro VFA production and/or increases the digestibility of fiber and starch. A 4 x 4 x 4 factorial arrangement was used. The main factors were feed source, length of fermentation, and level of added Propionibacterium. Fermentations were conducted in batch cultures with Propionibacterium added to the flasks just ...

Dry matter and cellulose digestibility were not affected by the urea infusions. The apparent nitrogen digestibility, derived from the difference between feed and faecal N, and ignoring infused N, was slightly depressed by urea infusions of from 9 to 34 g N/day, but at the highest level of infusion (43.7 g N/day) it was equal to or greater than the control value. Rumen pH and VFA concentrations ...

The present study evaluated the effects of different cutting height on nutritive value, fermentation quality, in vitro and in vivo digestibility of whole crop barley silage. Whole crop barley forage (Yuyeon hybrid) was harvested at height of 5, 10, and 15 cm from the ground level. Each cutting height was rolled to make round bale and ensiled for 100 days. After 100 days of ensiling, pH of silag...

Forty-eight crossbred weaner pigs divided into three groups of sixteen pigs each were used to assess the effect of feeding frequency on the performance and nutrient digestibility. The same type and quantity of feed was rationed once, twice and thrice daily. Performance of pigs fed twice daily was better than those fed once per day. Digestibility of dry matter, crude protein and crude fibre incr...

published data on the effects of essential oils (eo) on in vivo nutrient digestibility in sheep are contradictory. in 2 experiments, the effect of thymol and carvacrol on nutrient digestibility was studied in sheep fed with high (70%) or low (52%) concentrate diets, using incomplete latin square designs. the essential oils were mixed with the concentrate portion of the diet at the rate of 0.0, ...

The effect of substituting native grass with jengkol (Archidendron jiringa) by-product on fermentation characteristics, rumen microbial profile, methane production, and hydrogen balance using in vitro method was investigated. Seven treatments (different composition of native grass, jengkol peel, jengkol leaves, and concentrate) with five replications in a block randomized desi...

Plants growable in rangelands play an important role in the feeding of ruminants; hence, the nutritive value of four plants (Falcaria vulgaris, Malva neglecta, Chenopodium album, and Polygonum aviculare) was determined by different laboratory methods. The plant samples were randomly collected in vegetative phase from different rangelands of Torbat-e Jam, Iran in spring 2018. The range of dry ma...

The method of Boisen and Fernandez [Boisen, S., Fernandez, J.A., 1997. Prediction of total tract digestibility of energy in feedstuffs and pig diets by in vitro analyses, Anim. Feed Sci. Technol. 68, 277–286] for measuring in vitro fecal digestibility of organic matter (OMdv) or in vitro digestible organic matter content (DOMv, g/kg) was used on 113 compound feeds (79 as mash and 34 as pellets)...
