This study was conducted to investigate the effect of soybean meal (SM) and soluble starch (SS) on biogenic amine production and microbial diversity using in vitro ruminal fermentation. Treatments comprised of incubation of 2 g of mixture (expressed as 10 parts) containing different ratios of SM to SS as: 0:0, 10:0, 7:3, 5:5, 3:7, or 0:10. In vitro ruminal fermentation parameters were determine...

The present study was conducted to investigate the possibility of using a modified in vitro gas production technique in place of the nylon bag method to estimate protein degradability of alfalfa hay in ruminants. In the in situ experiment dacron bags were filled with 3 g alfalfa hay. This was incubated in the rumen of three ruminally cannulated Ghezel rams for the periods of 0, 2, 4, 8, 12, 16,...

The objective of this study was to investigate the effects of inulin [as topinambur (Helianthus tuberosus L.) powder] on in vitro rumen fermentation of diets containing hay and pelleted concentrate for sheep (approximately 60:40%) in artificial rumen (the RUSITEC system). The RUSITEC system consisted of six fermentation vessels. Topinambur powder was added at levels of 0.2, 0.4, 0.6, 0.8 and 1....

Effect of UMMB supplementation on rumen profile in buffalo calves was undertaken with the objectives to study the effect of UMMB on rumen microbiology and rumen metabolites. Eight apparently healthy male buffalo calves of 10 to12 months age and weighing between 100 to 150 kg were used as experimental animals. They were divided in to control and treatment groups consisting of 4 animals in each g...

1. A method for estimating the proportions of bacterial- and protozoal-N in the total non-ammonia-N reaching the lower gut of the ruminant under steady-state conditions was evaluated. Three trials using two different diets were conducted with a Holstein steer equipped with a rumen cannula and duodenal re-entrant cannulas. 2. An intraruminal primed infusion of (15NH4)2SO4 was administered for 68...

Acta vet. Brno, 58, 1989: 225-243. Peracute rumen alkalosis was induced by intraruminal administration of urea @ 1.25 g/kg. b. wt. as a single dose in six healthy male Murrah buffalo calves of about 1 2 ...

Compost liquor results from the percolation of precipitation through composting waste; the release of liquids from high moisture content feedstocks; and as a result of runoff from hard surfaces and machinery. This research aimed to establish the potential for waste materials to act as media for low-cost compost liquor biofilters. Six types of potential biofilter media were packed into experimen...

in this experiment, different doses of zataria multiflora (zm) and eucalyptus globolus (eg) essential oils (eos) (0, 100, 250, 500, 750 and 1000 µg/ml) and a mixture of them were added to alfalfa hay incubated with buffered rumen liquor of merghoz goat to assess in vitro gas production, rumen fermentation and protozoa population. in all treatments the asymptotic gas volume (b) and the rate cons...

the aim of this research was to study the in vitro effect of lavandula officinalis (leo) and origanum vulgare (oeo) essential oils on rumen fermentation using a concentrate type substrate (cts) and roughage type substrate (rts). six mehraban ewes were divided into 2 groups and fed a concentrate type or roughage type diet, and used as rumen fluid donors. each essential oil (eo) was evaluated sep...
