In this study, the rumen metabolism of four ruminant species – blackbuck (Antilope cervicapra), barbary sheep (Ammotragus lervia), sika deer (Cervus nippon dybowskii) and addax antelope (Addax nasomaculatus) – from the Nuremberg Zoo was investigated in relation to their feeding management. Parameters of microbial fermentation in the rumen as well as rumen tissue samples were examined. Additiona...

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...

Background: This study was carried out to evaluate the effect of supplementing ruminant ration with propionibacterium P169 by using 3X3 Latin square Rahmani rams on feed intake, nutrients digestibility, rumen fermentation, blood plasma metabolites. Methods: Rams were divided into three groups with three successive experimental periods. Each period consisted of 21 days. Animals were fed on: rati...

Inadequate supply of glucose or glucogenic substrates to the body tissues can affect metabolism of absorbed acetogenic metabolites from the gut and therefore, influence feed intake in ruminants. This study investigated the effect of energy supplementation on rumen kinetics in the gut, and the acetate clearance rate in the body tissues of sheep fed low quality basal roughage. A basal diet consis...

This study examined the reticulo-rumen characteristics of the microbial community and its fermentative characteristics in milk-fed, at weaning and finished lambs in a conventional fattening system. Five lambs were assigned to each of three groups: milk-fed lambs slaughtered at 30 days (T30), weaned lambs slaughtered at 45 days (T45) and 'finished lambs' slaughtered at 90 days (T90). At slaughte...

This study was carried out to determine the effects of supplementing different levels (0, 0.5 and 1% of buffered rumen fluid) of methanolic extract of pomegranate peel, on rumen fermentation kinetics of four oil seed meals (soybean meal, cotton seed meal, rapeseed meal and sunflower seed meal), using in vitro gas production technique. The samples were incubated in syringes containing rumen liqu...

The objective of this study was to determine if the length of chop of processed corn silage influences the impact of supplemental fat on rumen fermentation and performance of dairy cows. We hypothesized that increasing forage particle length may alleviate the interference of fat on rumen fermentation. Sixteen Holstein cows averaging 120 d in milk were used in a replicated 4 x 4 Latin square des...

This experiment was conducted to study the effects of various amounts of treated sunflower meal (SFM) with extracted tannins from pistachio hulls on in vitro gas production and ruminal fermentation in ruminants. The SFM was treated with pistachio extract concentrate (PEC), which contained 111.40 g kg-1 total phenol and 71.30 g kg-1 total tannin per dry matter of extract, at six experimental tre...

One cause of a reduction in the efficiency of feed utilisation in the rumen is the non-specific lysis of bacteria within the rumen and subsequent fermentation of the bacterial protoplasm. Bacteriophages are implicated in this lysis, are obligate pathogens of bacteria and occur in dense populations in the rumen. Large numbers are present (up to lo*’ per millilitre of fluid) in the rumen. These v...

This study was aimed to evaluate the in vitro effects of medicinal herb extracts (MHEs) on ruminal fermentation characteristics and the inhibition of protozoa to reduce methane production in the rumen. A fistulated Hanwoo was used as a donor of rumen fluid. The MHEs (T1, Veratrum patulum; T2, Iris ensata var. spontanea; T3, Arisaema ringens; T4, Carduus crispus; T5, Pueraria thunbergiana) were ...
