Abstract

SUMMARY
Pirst study :
Fodder Beet Silage as Effected by Different Cultivars
and Potassium Bisulfate Treatment
Fourteen cultivars of fodder beet were ensiled for a varital
comparative study. These cultivars were grown in two locations
(Sids~ and Nubaria).
The fourteen cultivars are listed as follows :
1) Rota 2) Poly aurea 3) Hamara 4) Solamka 5) Peramono 6) Solano
7) SOlar 8) Polyqrominqia 9) Maioral 10) MonovBrt 11) Briqader
12) Honored 13) Xyr08 and 14) Remilenger evs.
Sowing was done on the first week of November, 1984 and the
harvestig was conducted during the first week of JUly, 1985.
Oo~l.tly rand.omy••d ~lock de,iqn for the various culelv_r_
in 4 replications was used.
Pre-ensilage preparation and conditioning using potassium
bisulfate-wilting treatment were done as well as water-silting, and
freshly ensiled beet for comparison. Combined analysis was done for
the two locations.
* Results could be summarized as follows :
1. In summary, the advantages of chemically-wilted compared with
water-wilted treatments in respect of the natural characteristics
-
(colour, ador, foam, and texture) of the produced silage could be
due to antioxidant effect of potassium bisulfate during wilting
and: ensiling as well.
2. Respiratory-fermentation loss was affected by the applied preensiling
treatments and the cultivars.
3. Overall of the tested beet-cultivars, respiratory-fermentation
loss of the silage was significantly higher for Nubaria than Sids.
4. The interaction effectaf the location and cultivars was significant
for this loss. In other wards the respiratory-fermentation loss
was significantly higher in Nubaria than Sids for same cultivars.
Whereas, an Opposite trend was noticed in 8ome, other Qultivar ••
51. Effluent loss was higher for the rreshly ensiled treatment by 79’
;
than the water .w•i.lted •.t.reatment. And, the effluent loss for the
water-wilted treatment was higher by 83\ than the chemically-wilted
pre-ensiling treatment.
effluent loss overall of the tested cultivars, where slightly higher
loss was obtained in Nubaria as compared with Sids.
7~ There was no significant difference in the net silage weight of
water-wilted and the cheaically-wilted beet slices over the tested
cultivars. However, freshly ensiled beet showed a significant
reduction in the net silage weight compared with either water-wilted
or chemically-wilted beet slices as a pre-ensiling treatment.
8. Results showed that the ensiled beet cultivars had a significant
effect on the net silage weight of the obtained silage.
Net silage weight was slightly but significantly higher in Sids
than in Nubaria.
9. The interaction effect of the cultivars and location on the net
silage weight was significant.
10. Respiratory-fermentation loss of the silage was positively correlated
with effluent loss with (r= 0.186), and negatively correlated with
net silage weight (r; 0.974). However, effluent loss was inversely
corelated with the net silage weight (r= 0.401).
~1. Silage of the chemically-wilted treatment had a significant lower
pH value than either water-wilted or the freshly packed b••t silage.
However, there was no significant difference in pH of the two later
treatments.
12. Results showed significant differences in the pH values of the
chemically-wilted beet silage of the different cultivars.
13. Freshly ensiled silage had the lowest dry matter percentage and
the silage of the chemically-wilted treated silage had the highest
dry matter percentage.
4. ’lbe obtained variatiOD in dry matter percentage amcmg the silage
of different beet-cultivarswasextremely and significantly different.
5. Results showed a significant dry matter superiority of silage in
Sids location for some of the tested cultivars. Whereas, opposite
significant results were recorded for other cultivars.
16. Overall of the tested beet-cultivars, pre-ensiling treatment of
chemically-wilted beet slices produced the highest total sugars
percentage cOlDJ?aredwith the water-wilted or the freshly ensiled
beet.
17. Chemically-wilted silage had a significantly higher total sugars
percentage in Sids than in Nubaria.
18. Dry matter percentage of the silage was positively correlated
with the total sugars with correlations coefficient of (r= 0.562).
19. Pre-ensiling treatment of chemically-wilting produced silage that
had significantly higher crude fiber, crude protein and fat
percentage oompared with the water-wilted s11age. These results
were over the whole tested cultivars.
20. It 1$ well noticed that the variation in the obtained silage for
the different beet cultivars was almost double for crude protein
and crude fiber with no much changes in fat percentage. Bftects ot
the tnteraetions between eultivars, locations, and pre-ensiling.
treatments on the above contents were studied.
2•• Correlation coefficients between the above characteristics were
recorded.
2~. Acetic acid, Lactic acid Valiric acid and Butyric acid percentages
were determined in the produced silage. Higher lactic and valiric
acid and lower butyric acid percentage were recorded for the
chemically-wilted silage compared with the water-wilted silage.
2~. Proper linear regression equations for estimating some quality
parameter’s values were generated.
