Abstract

Seed production could be affected by plant age due to different physiological activity. These research aimed to evaluate the effect of different age on Indigofera zollingeriana seeds production and characteristics. The study was conducted on plants at 1, 4, and 8 years old. The variables measured were pods production, pods characteristics, seed weight, and seed characteristics. Data were analyzed by Analysis of Variance Matrix Unbalance by software R 3.3.2 and Correlation Analyses.  Results showed that plant age increased  (p<0.01) pods length and diameter; and seed diameter and thickness. Plant age had positive corellation to increased dry weight of pods, seed weight, percentage of seed weight per pods, average weight of 1000 seeds. It concluded that plant age could increasing pods length and diameter; and seed characteristics.  Therefore, I. zollingeriana plant could be seed sources until 8 years old

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

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.

Abstract

The objective of the study was to evaluate whether mannanase supplementation in the low protein diet fed to laying hens from 31 to 45 weeks of age would improve egg production and quality. The experiment was designed into completely randomized designed with 2 treatments and 20 replicates. Two hundred and thirty six  31-week old ISA brown hens were distributed at random to individual cage. Two experimental diets containing 15% protein without (0%) or with mannanase supplementation (0,05% [72,5 MU/kg product Elanco, Animal Health IN, USA] ) were assigned to cages, so each treatment had 20 replicates with 5- 6 birds per treatment. Feed intake, egg production (hen day and egg mass), egg weight, and feed conversion ratio (FCR) were recorded every week in the period of 31-35 weeks and 42 to 45 weeks of age. On Week 34 and 45, eggs were collected for egg quality analysis (albumen height, haugh unit, yolk color, shell thickness, shell strength and shell weight). Data were subjected to one way of ANOVA (with 20 replicates per treatment). The results showed that mannanase supplementation had had no effects on performance parameters (feed intake, egg production, egg weidht, and FCR) measured at 31 to 35 weeks of age, but had significant effect (P <0,05) on daily feed intake, and FCR on 42 to 45 weeks of age. With regard to egg quality, only egg shell weight was improved by mannanase supplementation. In conclusion, dietary supplementation to low protein diet could improve feed conversion and egg shell quality.

Abstract

ABSTRACT Ration in pellet form could increased feed efficiency level compared to mesh in poultry. The objective of the research was to  evaluate Morinda citrifolia leaves in ducks ration on the pellet physical quality and rancidity level after storing. The treatments diet contained 18 % of crude protein and 3000 kkal kg-1 metabolizable energy.  Pelleting diet process used simple wood pellet without steam, pellet knife and coller. The experiment was factorial using completely randomized design. Factor A was the percentage of mengkudu leaves (0, 2.5, 5 and 7.5%). Factor B was the period of storage (0, 3 and 6 weeks). The data were analyzed by using analysis of varian (ANOVA) and Duncan Multiple Range test. The variables were moisture content, water activity, density, compact bulk density, bulk density, pellet durability, pellet durability index, angle of repose, particle size, peroxide value, and fat content. The result showed that supplementation of Morinda citrifolia leaf and storage period significantly (P<0.05) affected the water activity and moisture content. Supplementation 7.5% of Morinda citrifolia leaves reduced (P<0.05) pellet density. The average pellet density in 0% Morinda citrifolia and 7.5% Morinda citrifolia were 1.27 g mL-1 and 1.22 g mL-1 respectively. Storing ducks pellet up to 6 weeks decreased physical pellet quality as indicated by increasing moisture content, water activity and the peroxide value. Keywords : Morinda citrifolia, pellet diet, peroxide value, storage
