Abstract

This research was aimed to analize blood profiles and metabolites of sheep fed bitter cassava leaves (Manihot glaziovii) meal supplemented with cyanide degrading bacteria and sulphur. The research used 15 local male sheeps (Garut), with average of aged 7-9 month and body weight 21.45 ± 3.33 kg. The sheep are placed in individual cages and kept for90 days. The experimental design was a block randomized design with 3 treatments and 5 replicates. The treatments were P1 = control (40% napier grass : 30% cassava leaves meal : 30% concentrate), P2 = P1 + cyanide degrading bacterial, and P3 = P2 + sulphur. Variables served were leukocyte, erythrocyte, haematokrit, haemoglobin, monocyte, basophil, limphocyte, neutrophil, eosinophil, neutrophil limphocyte ration, glucose, protein total, albumin, and triglyceride of blood. Data were analyzed by using analysis of variance. Any significant differences were further tested using Duncan Multiple Range Test. The results showed that cyanide degrading bacteria and sulphur supplementation did not affectblood profiles and metabolites of sheep, except eosinophil proportion. The used of cyanide degrading bacteria or its combination with sulphur to the sheep fed ration contain bitter cassava leaf meal very significantly decreased (P<0.01) eosinophil proportion. In conclution, cyanide degrading bacteria and sulfur supplementation to the sheep fed ration contain bitter cassava leaves meal did not alter blood profiles and metabolites, but could improved body defense in the toxic detoxification.Key words: blood profiles, blood metabolite, cassava leaf, cyanide degrading bacteria, sheep

Abstract

 Indonesia is a maritime country, rich in biodiversity such as seaweeds which have potential as animal feedstuffs. Previous study showed that the seaweeds high in ash contents and have potential as mineral sources for dairy cattle. This study was aimed to compare several seaweeds species’s (Sargassum sp., Gelidium sp., Gracilaria sp., Eucheuma cottonii and giant Eucheuma cottonii) potential as mineral sources for dairy cattle. Parameters observed in this study were macro mineral contents (Ca, P, Na, Cl, Mg, S), the mineral solubility in HCl and rumen liquor, and estimate of their availability in rumen and abomasum. This study used completely randomized design except for solubility in rumen liquor study which was used completely blocked design. The collected data were analysed using ANOVA followed by Duncan multiple rank test except for mineral contents which used descriptive statistics. The results showed that all seaweed tested high in macro mineral contents except for Gelidium sp. Their solubility in HCl and rumen liquor were also high. It is concluded that all seaweed tested were good mineral sources for dairy cattle, except for Gelidium sp.

Abstract

Age of harvesting determine the maize forage condition prior to ensilage which influence the quality of silage produced. Nowadays, maize silage increasingly popular among smallholder dairy farmer in tropical lowland area, however, their optimum age of harvesting to produce the best silage quality have not been intensively studied. This experiment was aimed at finding the best age of maize plant to produce the best quality silage for tropical lowland. Four treatments (age of maize at harvesting), namely 60 d (T1), 70 d (T2), 80 d (T3) and 90 d (T4) of harvesting have been tested in producing whole plant maize silage. The silage was made in 2 kg laboratory plastic bag silo capacity and ensiled for 5 weeks. Physical (color, odor, texture, moisture and spoilage), fermentative (WSC, pH, DM, dry matter degradation, VFA, PK, protein degradation, NH3 and fleigh number), utility characteristic (in vitro rumen fermentability and digestibility) characteristics have been observed. Completely randomized design were used in this experiment except for utility characteristics which used block randomized design. Physical characteristics were analyzed using descriptive statistics, while fermentative and utility characteristics were analyzed using ANOVA. Significant different among the treatments were tested using polynomial orthogonal to find the best age of plant to produce the best silage quality. The results showed that DM content of maize plant increased linearly with the ages, but CP content decreased cubically in opposite curve shape to WSC content. The best silage quality material with 30% DM were not reached even at 90 d of harvesting. However, its CP contents decreased sharply after 80 d. Physical characteristics of the silage showed that no different between the treatments except for percentage spoilage silage. The lowest spoilage percentage was achieved if the plant harvested at 68 d, while the highest spoilage percentage was at 75 d. No statistically significant different were found in fermentative characteristic of silage among the treatments. All fermentative characteristics showed the silage in very good qualities. The DM loses during ensiling were not significantly influenced by the plant ages, although there were a trend toward decreasing number of loses with increasing of maize age of harvesting. Protein loses during ensiling were not influenced by the maize age. Fleigh number of the silage significantly increased after day 80. Fermentability of protein reduced with the age, while organic fermentability remained the same. Dry matter and organic matter digestibility of the silage were the best at day 90. It is concluded that the best whole maize silage quality in tropical lowland were resulted from maize harvested at 90 d.Keywords: maize, silage, tropical lowland, dairy, age harvesting

Abstract

Indigofera zollingeriana is a shrubby legume which highly accepted as fodder to animal ration because of its high protein content. As a legume, this plant could provide itself a nitrogen because of its symbiotic relationship with rhizobia. Moreover, there are some other bacteria could be found in root nodule which also supports plant growth. This experiment was aimed to find rhizobia or Nodule-Associated Bacteria from Indigofera zollingeriana and its cross-nodulation capability on mungbean (Vigna radiata). Indigofera zollingeriana root nodules were collected from three different locations. Total of 9 isolates were collected and cultured on Yeast Extract Mannitol Agar (YEMA). Isolates were also tested for nodulation on I. zollingeriana and mungbean. Five days old isolate were inoculated to I. zollingeriana and mungbean seed for approximately 30 minutes and then sown into sterile sand. This experiment was designed in completely randomized design with three replications. Colonies morphology, Gram`s nature, nitrogenase activity of asymbiotic isolates, nodules number, nodules fresh weight, were observed. Isolates showed a raised glistening white colonies. Most of isolates showed a gram negative, but JP1 and KF isolate were found to be a gram positive. All isolates possesed a nitrogenase activity. Nodulation test showed that all isolates could renodulate I. zollingeriana better than control. BM isolate, which had the lightest nodule fresh weight on I. zollingeriana, could increased nodulation  13.62% better than the uninoculated treatment. Different case was found on mungbean, only JM1 and BM isolate that could nodulate better than control.
