Sixteen male Markhoz kids (13.2±1.6 kg live body weight, 3 months old) were used to evaluate the effects of a commercial bacterial probiotic supplement on growth performance, nutrients digestibility, meat quality attributes and fatty acid profile of triceps brachii muscle and omental fat based on a completely randomized design with two treatments and eight replicates. The Primalak probiotic was fed daily in the amount of two grams to each kid in the respective treatment. Growth performance parameters, including average daily feed intake, average daily weight gain, and feed conversion ratio were not affected by bacterial probiotic feeding. Digestibility of diet’s chemical components showed no significant difference between treatments. Similarly, the quality attributes of triceps brachii muscle, including pH24, drip loss, water holding capacity, and chemical composition had similar values in both experimental treatments. Kids with access to bacterial probiotic had significantly lower saturated fatty acids, higher mono-unsaturated fatty acids and greater unsaturated to saturated fatty acids ratio in examined muscle (P<0.05). However, with the exception of lower C15:0 concentration in kids receiving bacterial probiotic (P<0.05), fatty acids profile in omental fat tissue did not change in response to probiotic consumption. It can be concluded that Primalak multi-strain probiotic with the mentioned dosage (2g/d/h) is not an effective additive to make significant changes in nutrients digestibility, Markhoz kid’s performance, meat quality attributes and fatty acids profile of different fat tissues.

Abstract
This experiment was aimed to study the effect of multi enzyme and bacterial inoculant on chemical composition and fermentation parameters of barley silage. Robovio multi enzyme was added at three levels, 0, 500 and 1000 mg/kg of barley dry matter (DM) and Prosage bacterial inoculant (a mixture of Lactobacillus ...

This experiment was aimed to study the effect of multi enzyme and bacterial inoculant on chemical composition and fermentation parameters of barley silage. Robovio multi enzyme was added at three levels, 0, 500 and 1000 mg/kg of barley dry matter (DM) and Prosage bacterial inoculant (a mixture of Lactobacillus buchneri,Lactobacillus plantarum, Enterococcus faecium and Propionibacterium acidophilus) was added at three levels, 0, 5 and 10 mg/kg of silage DM. Chemical composition, in vitro gas production, protozoa population and protein fractions of experimental silages were measured. Results showed that multi enzyme addition decreased NDF (P<0.05), pH, ash, B2 and C fractions (P<0.01) and increased A and B3 fractions (P<0.01) compared to the control. Barley silage containing 5 mg bacterial inoculant had greater DM, pH and B2 fraction (P<0.01) and lower C fraction compared to the control and silage containing 10 mg of bacterial inoculant. Protozoa population, N-ammonia concentration, estimated metabolizable energy, short chain fatty acids and in vitro organic matter digestibility were not affected (P>0.05). Based on these results use of bacterial and multi enzyme additives for the preparation of wilted barley silage is not recommended due to their costs.
