The aim of the study was to evaluate the use of Calliandra leaves (Calliandra calothyrsus) as a protein source in the Kacang goat’s diet and as an alternative to substitute the use of soybean meal (SBM) in goat’s diets. The proportion of C. calothyrsus feed substitution and SBM is T1 = odot grass (ad libitum) + 100% SBM; T2 = odot grass (ad libitum) + 25% C. calothyrsus + 75% SBM; T3 = odot grass (ad libitum) + 50% C. calothyrsus + 50% SBM; T4 = odot grass (ad libitum) + 75% C. calothyrsus + 25% SBM; and T5 = odot grass (ad libitum) + 100% C. calothyrsus. The last 10 days, collections was conducted include total collections of feeding, the residue of the feed, and feces. The parameters observed were intake and nutrient digestibility of dry matter (DM), crude protein (CP), neutral detergent insoluble nitrogen (NDIN) (% CP), and acid detergent insoluble nitrogen (ADIN) (% CP). Data obtained from the study were analyzed using a one-way analysis of variance, then if the results show significant differences, it will be analyzed further with Duncan's new multiple range test. The results showed that C. calothyrsus substitution treatment of 25 to 100% (T2, T3, T4, T5) gives noticeable influence (P<0.05) for nutrient intakes, excretion (feces), and digested nutrients. The highest intake and digestible fraction of N-NDF, N-ADF, NDIN, and ADIN is the T5 treatment, which is the replacement of SBM with 100% C. calothyrsus (P<0.05).
Twenty goats were given a basal feed of Pennisetumpurpureum cv Mott (odot grass) and supplemented with protein-based feed ingredients namely calliandracalothyrsus and soybeanmeal (SBM). The proportion of calliandra feed substitution and soybeanmeal is T1 = odot grass (ad libitum) + 100% soybeanmeal; T2 = odot grass (ad libitum) + 25% calliandra + 75% soybeanmeal; T3 = odot grass (ad libitum) + 50% calliandra + 50% soybeanmeal; T4 = odot grass (ad libitum) + 75% calliandra + 25% soybeanmeal; and T5 = odot grass (ad libitum) + 100% calliandra. The amount of feed supplementation given is based on daily protein requirements (gram/DM) per day according to animal body weight. The feed given contained iso protein (CP) and iso energy (TDN) to determine the effect of substitution of soybeanmeal with calliandra The parameters observed were intake and nutrient digestibility of feed. Data obtained from the results of the study analyzed variance using a one-way analysis of variance, then if the results show significant differences, it will be analyzed further with Duncan's new multiple range test. The results showed that substitution of calliandra did not have a significant effect (P> 0.05) on nutrient intake (g/kg BB0,75/day), except for intake of ETN, it shows a significant effect (P< 0.05). Calliandra substitution had a significant effect (P<0.05) on feed nutrient digestibility, with the highest digestibility being T2 treatment (25% calliandra substitution).
This study investigated the nutritional potency and efficacy of tannin-containing forages as anti-parasites sources to support the performance of female Bligon goats. Fifteen female Bligon goats were divided into 3 different groups based on feeding treatments. The first group (KG) served as the control and was fed 100% king grass (dry matter basis). The second group (KGC) was fed 50% king grass and 50% Calliandra calothyrsus leaves (dry matter basis). The third group (KGA) was fed 50% king grass and 50% Artocarpus heterophyllus leaves (dry matter basis). The study showed that supplementation with tannin-containing forages could improve feed consumption and the digestibility of dry matter (DM), organic matter (OM), and crude protein (CP). The groups that received tannin-containing forages had higher body weight gains at 22.85 g/day and 29.52 g/day for KGC and KGA respectively than the control group. The anti-parasites effects were successfully indicated by the declining number of coccidian oocysts in the feces (number/gram feces), which were 3,166; 841; and 450 for KG, KGC, and KGA respectively. Tannin-containing forage supplementation could improve the consumption and digestibility of DM, OM and CP. Supplementation improved the daily body weight gain. The number of coccidian oocysts in animals receiving supplementation was also reduced. The greatest effects on fecal coccidian oocyst reduction were attained with Jackfruit leaves (Artocarpus heterophyllus) supplementation
The study aimed to evaluate the usage of Calliandra leaves as protein source in Kacang goat’s diet at Wonolagi, Gunungkidul. Fifteen female Kacang goats weight 20 to 23 kg were plotted randomly into three diets treatments. The diet consisted of basal diets (local forages provided by farmer’s practices) with three different treatments: 100% Calliandra (T1), 50% Calliandra + 50% Soybean meal (SBM) (T2), and 100% SBM (T3). Parameters observed in this study were: feed intake (Dry matter intake, DMI; Organic matter intake, OMI; Crude protein intake, CPI; and Crude fiber intake, CFI) and ruminal fermentation parameters after 3 hours feeding period (pH value, total volatile fatty acid (VFA), acetate, propionate, butyrate, and A:P ratio). Collected data were analyzed using one-way ANOVA and the difference between means were analyzed using Duncan’s Multiple Range Test. DMI, OMI, and CFI did not differ among treatments, however, greater SBM content in T3 improved CPI 34.21% significantly (P<0,05) compared to T1. Ammonia, total VFA, acetate and propionate profile were greater in T2 diets compared to T1 (P<0.05). In conclusion, the use of Calliandra to substitute SBM should be in the 50 to 50 ratio to optimize the feed intake and ruminal fermentation profile.
