Abstract

This study aimed to explore physical characteristics and its correlation to feed digestibility in goat.Sixteen Ettawah Grade goats in the second milk production periods and in the 4-5th month of lactationwere used in this study. The study was arranged with completely randomized block block design basedon milk production as replications. The goats were fed ration containing 16% of crude protein and 65%of total digestible nutrients (TDN). Some of crude protein content were supplied by urea. The treatmentswere control ration (without urea; T0), ration with 0.4% urea (T1), ration with 0.8% urea (T2), andration with 1.2% urea (T3). Parameters observed were feed digestibility, fecal extended level (FEL), andfecal rough particle distribution (FRPD). Data were analyzed using correlation-regression to find thecorrelation between fecal characteristics and feed digestibility. The results showed that urea content inthe rations up to 1.2% of dry matter did not affect dry mater digestibility, water content and fecalcharacteristics (FEL and FRPD). There were highly negative correlation (r= -0.665) between feeddigestibility and water content of feces as well as feed digestibility and FEL (r= -0.553), whilecorrelation between digestibility and FRDP was positive (r=0.608). The conclusion of this study waswater content, degree of FEL and FRPD can be used to determine the quality of feed. If feces composedof finer texture, dried and small particles indicated having better digestibility, while if feces composed ofrough texture, wet, and large particles indicated having low digestibility.

Abstract

This study aimed to determine the use of L. plantarum starter on a complete ration silage made from water hyacinth on consumption of nitrogen free extract (NFE), partial volatile fatty acids (VFA) production, methane production, and blood glucose concentration of sheep. This study used fifteen rams (12 months old with an average body weight of 19 ± 3.98 kg). Sheep were randomly divided into 3 groups of treatment rations, namely the group given: concentrate ration and elephant grass (T0), complete ration silage provided without the addition of L. plantarum starter (T1), and complete ration silage provided with the addition of L. plantarum starter (T2). Ration was formulated isocaloric and isoprotein (CP 13%, TDN 65%). The results showed that the consumption of NFE, the concentration of propionic acid, butyric acid and blood glucose before and post feeding was not significantly different, whereas the concentration of acetic acid, the ratio of C2:C3 and methane production was significantly different (P<0,05) among treatments. The concentration of acetic acid of treatment T0, T1 and T2 was 36.52, 28.86, and 32.43 mM, respectively. Methane concentration was 19.95, 16.08, 17,55 mM, respectively for T0, T1, T2 and glucose concentration was 45.50, 70.30, and 53.24 mg/dl, for treatment T0, T1, T2, respectively. In conclusion, provision of silage ration complete which was provided with or and without L. plantarum starter was much better compared to control ration, (concentrates with elephant grass).

Abstract

The research was conducted to evaluate the effect of addition of tannin, saponin or combination of tannin and saponin to the concentrate of the ration on the microbial population and fermentability of feed in vitro and to assess the best dosage of uses. The research was arranged according to completely randomized design with four treatments and 3 replications. The treatments were ration without tannin and saponin (T0), ration with 1.2% saponin (T1), ration with 0.5% tannin and 0.9% saponin (T2), ration with 1% tannin and 0.6% saponin, (T3), ration with 1.5% tannin and saponin 0.3% (T4) and ration with 2% tannin and 0% saponin. the results of the experiment showed that the addition of the tannin, saponin or their combination altered microbial population in the rumen. Protozoas population decreased significantly whereas bacterial population was increased. NH3 production increased while ratio of acetaic to propionic acid tended to decrease. Total gas production increased 62.59-69.35 ml/200 mg of dry matter. The addition of 1% tannin and 0.6 % saponin shows the best effect to control protozoa population and feed fermentability in the rumen.

Abstract

The aim of the experiment was to find the most appropriate supplement for sheep fed on vegetable waste silage?based diet to produce better weight gain. Sixteen male local sheep (average body weight of 13.27+2.82 kg ) were randomly divided into four groups according to completely randomised design.  Each group received one of four treatments i.e. T0 (50% field grass + 50% concentrate), T1 (50% silage of vegetable waste + 50% concentrate), T2 (T1 diet + mineral Zn 20 ppm, Cr 2 ppm), and T3 ( T2 diet + 1% alginate). After two weeks of preliminary period, sheep were subjected to 12 weeks of observation. In general, the vegetable waste silage based diet (T1,T2, T3) resulted in better crude protein (CP) intake and weight gain than the T0 diet.  Each treatment of T0, T1, T2, and T3 resulted in Protein consumption of  36,48 ; 45,81 ; 53,59 ; 40,75 g, and weight gain of 75; 105; 121; 109 g/day, respectively. Mineral supplementation (T2) resulted in higher rates of weight gain and feed efficiency compared to the mixed mineral and alginate supplementation (T3), therefore leading to the conclusion that only Zn and Cr mineral supplementation is needed for the vegetable waste silage used as sheep ruminant feed.

Abstract

Some oligosaccharides have been shown to modify colonic micro flora composition andactivity in many humans and some animal species. Some oligosaccharides tend to elevate beneficialbacteria and the others depress harmful bacteria in gastrointestinal tract.  However, little data areavailable on their fermentation characteristics by the ilea microbial community, and their effects onthe colon micro flora composition. The aim of this study was to evaluate the in vitro effect ofoligosaccharides from apple and banana peel extraction and mannan-oligosaccharide (MOS)commercial on concentrations of the total anaerobic bacteria, Bifidobacterium, Lactobacilli, Coliformad Esheihia oli populatio i dai alf’ olo otets. To goups of 2 ales fed a ilkreplacer (1 week old) and fibrous pellets (3 weeks-old) were sacrificed 5 h after the morning meal. Ineach group, colon content were pooled and diluted with, diluted by Lowe medium. Extraction ofapple, banana peel, and MOS were tested in vitro versus a control. Each bottle was incubated induplicate for each treatment and at 370C in a shaking water bath. Bacterial concentrations weredetermined at 48 H and inoculated in selected media for each bacteria group and supernatant weretaken for fatty acids (VFA) measurement. Result showed in general, oligosaccharides were notresulted VFA concentration than control bottle in both groups even tend to inclined, specificallybanana peel. Apple peel and banana peel slightly increase total anaerob and lactobacilli in bothgroup but could not depress the E. coli. On the other hand MOS seems the most effective indepressing coli. Based on our results, oligosaccharides were fermented by bacteria of ilea contentsin dairy calves and its fermentation led to a selective stimulation of host bacteria.Key Words: Oligosaccharides, Dairy Calf, Colon, Selective Media
