Abstract:

This experiment was conducted to determine the possibility of replacing part of the barley grain by hydroponic barley fodder (HBF), and evaluating its effect on digestibility, rumen parameters, microbial protein synthesis and blood parameters in sheep. Four male Kermani sheep, 18-month-old (34.7 ± 1 kg live weight) were randomly assigned to a change over 4 × 4 design and fed the experimental diets for 21 d; 16 d for adaptation and 5 d for sample collection. Hydroponic-grown barley fodder replaced barley grain in the experimental diets. The experimental diets were: 1) control diet (without hydroponic barley fodder), 2) diet containing 7% of hydroponic barley fodder, 3) diet containing 14% of hydroponic barley fodder and 4) diet containing 21% of hydroponic barley fodder. Results showed that dry matter intake (DMI), nitrogen intake and retention and digestibility of nutrients increased (P

An experiment was conducted to evaluate the effects of replacement of barley grain with barley hydroponic fodder on blood metabolites and milk production of lactating Saanen goats. Eight dairy goats (45± 1.5 kg of live body weight and 3 months of lactation (88±6 days in milk)) were allocated to 4 experimental diets including the control diet and diets consisting of 37, 66 and 100 percent replac...

Nutrient digestibility in sheep fed diets containing Roundup Ready or conventional fodder beet, sugar beet, and beet pulp.

The objective of this digestibility assessment was to determine whether there are significant differences in the digestibility of Roundup Ready (glyphosate-tolerant) and conventional sugar beet, fodder beet, and beet pulp produced from sugar beet varieties when fed to sheep (seven wethers per treatment group). Three experiments were conducted in this assessment. Experiment 1 (35 wethers) compar...

Characterization of faecal microbial communities of dairy cows fed diets containing ensiled Moringa oleifera fodder

Moringa oleifera (M. oleifera) is a remarkable species with high nutritional value and good biomass production, which can be used as livestock fodder. In this study, we examined changes in the faecal microbiota of thirty dairy cows in response to alternative M. oleifera diets and their effects on nutrient digestion, milk traits and the faecal concentrations of short-chain fatty acids. No differ...

This research was conducted to investigate the effects of feeding of barley grain (whole or cracked) combined with two different protein sources (urea or soybean meal) on nutrients digestibility and rumen parameters (pH and ammonia concentration). Four rumen fistultated Mehraban sheep was used that the mean body weight of sheep was 36.5±0.5 kg. The the experiment was conducted in change over de...

This experiment was conducted to determine the effects of replacing corn by 20% barley supplementedwith probiotic, prebiotic and antibiotic on performance, immune response, intestinal morphology, carcass development and nutrient digestibility of broilers. Four hundred Ross 308 one day-old broiler chicks were assigned randomly to 5 dietary treatments and were tested for 42 days in a com...

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...
