Ferula assa-foetida L. is an important industrial and medicinal plant of Iran which is mainly distributed in arid and semi-arid areas of Khorasan province in north east of the country. Gum of this plant is widely used in pharmacological industry. This plant is endangered because of more harvesting and unsustainable harvesting methods. The objective of this study was to evaluate the effects of different cutting methods (conventional, cut of crown part, concave and surface) and times of cutting (5, 10 and 13 times) on gum yield of this species in its wild habitat in Mazar region in Bajistan. The treatments were studied under a factorial experiment which was arranged in a completely randomized design with three replications. Results showed significant differences among cutting methods and times of harvesting. Yield of gum was affected by times of harvesting and the highest yield was obtained in 10 cutting times. The highest and lowest gum yields were obtained in concave method with 10 cutting times (25.24 g/plant) and superficial method with 5 cutting times (2.02 g/plant), respectively. Results showed that conventional cutting method destroys crown buds, which causes death of the plant. The highest gum yields and the best plant regeneration rates were obtained by using of concave method with 10 cutting times.

Gum ammoniacum (Dorema ammoniacum D. Don) is one of the most important food, industrial and medicinal plants of Iran which is mainly distributed in semi-arid and desert areas. It is endangered due to superfluous and unsustainable harvesting methods. The objective of this study was to evaluate the possibility of crop cultivation in terms of dryland farming and the best operation method for collecting gum resin. For this purpose, the effects of different scarification methods (traditional, concave and staircase) and cut-off frequencies (5, 10 and 13 times) on gum yield of the five-year-old plants were studied at Toroq farm in Mashhad. The treatments were studied under a split plot structure in time experiment which was arranged in a completely randomized design with three replications. The rate of the root gum production and the rate of plant survival in the years after the withdrawal were measured, and finally the data were analyzed. Results showed no significant differences among cutting methods at p<0.05. The yield of gum was affected by times of harvesting and the highest yield was observed (p<0.01) in 13 cut-off times with 31.67 g/plant. The lowest gum yields were seen in 5 cut-off times with 5.84 g/plant. The traditional cutting method destroyed crown buds and caused the death of the plant (p<0.01). Reasonable gum yields and plant regeneration rates were obtained with the use of stairs method which is an easy method to be applied by the farmers or beneficiaries.

This study was aimed to evaluate the utilization of hydrolyzed Indigofera zolingeriana by celullase enzyme as the feed ingredient of gourami fish. This study used a completely randomized design which contained three steps, whereas each step contained four treatments and four replications. The first step performed by evaluating the Indigofera leaf meal (ILM) added with cellulase enzyme of 0 g/kg (control), 0.4 g/kg, 0.8 g/kg, and 1.2 g/kg. The second step was the digestibility test of ILM on gourami seeds. The third step was feed evaluation added with ILM as much as 0% (control), 15%, 30%, and 45% against the growth performance on gourami seeds. The gourami seeds used in the second and third steps with a weight of 13.65 ± 0.39 g/seed and 5.95 ± 0.15 g/seed, respectively. The addition of 0.8 g/kg and 1.2 g/kg cellulase enzyme could significantly decrease the crude fiber of ILM with 43.33%, besides having the best value of total, ingredient, protein, lipid, and energy digestibility. The growth performance of gourami seeds given 15% ILM added feed had the best value and insignificantly different from the control feed without ILM addition based on the specific growth rate (SGR), protein retention (PR), and feed efficiency (FE).          Keywords: Cellulase, feed, hydrolyze, Indigofera zolingeriana, Osphronemus gouramy.   ABSTRAK   Penelitian ini dilakukan untuk mengevaluasi pemanfaatan daun Indigofera zolingeriana yang dihidrolisis enzim selulase sebagai bahan baku pada pakan benih ikan gurami.

The objective of this research was to evaluate the supplementation of turmeric in the diet on antioxidant status and growth performance of African catfish (Clarias gariepinus) in zero water exchange condition. This study used a completely randomized design with 4 treatments and 4 replications. Each treatment consisted of feed supplementation turmeric at dosage of 0; 2.5; 5 or 7.5 g kg-1 diet. One hundred catfish juvenile (5.95±0.05 g) were stocked in intermediate bulk container (IBC) tank (1×1×1 m3) and rearing in zero water exchange condition for 60 days. Catfish were fed at satiation twice a day, in the morning and evening. The results showed that an increase in antioxidant content in catfish fed with the addition of turmeric, which simultaneously also reduced the percentage of liver damage. The parameters of liver damage can be seen from several parameters i.e. pale liver, droplet fat and fat content in the addition of turmeric treatment is lower than without the addition of turmeric. However, catfish fed with the addition of turmeric did not show significant results in terms of growth performances.

The growth performance and blood profile of forty-eight (48), six (6) weeks old rabbit bucks of cross (Chinchilla and New Zealand White) were assessed for 10 weeks. The bucks were allotted on weight equalization basis in a 2 x 4 factorial experimental layout composed of 24 rabbits into steel hutches and wooden hutches each and on four (4) varying levels (0, 5, 10 and 15 mL/litre of water, respectively) of oyster mushroom (Pleurotus ostreatus Jacq ex fr.) extract. Six (6) bucks were assigned to each treatment group and replicated three times with two (2) bucks per replicate in a Completely Randomized Design. The phytochemicals of the oyster mushroom extract showed that 9,12-Octadecadienoic acid (Z, Z)- methyl ester was the most abundant. Results showed that the feed conversion ratio was significantly (P<0.05) best (6.08) in bucks reared in wooden cage and administered 15 mL oyster mushroom extract. Significantly (P<0.05) highest triglycerides (81.00 mg/dL) was obtained in bucks on steel hutch and on 5 mL oyster mushroom extract and lowest (55.00 mg/dL) in bucks on steel hutch and on 10 mL oyster mushroom extract. The lowest (P<0.05) lymphocytes (59.00%) were recorded in bucks on wooden cage and administered 10 mL oyster mushroom extract. It was concluded that oyster mushroom extract up to 15 mL/litre of water administered in either steel hutch or wooden hutch did not impair the growth performance and blood profile of rabbit bucks.

A five-week study was conducted to determine the effect of feeding varying levels of S. cerevisiae on carcass and organ characteristics of finishing broilers. One hundred and twenty 4-weeks old broilers of cobb strain were randomly assigned to four treatments (T1 = 0.6 g Saccharomyces cerevisiae (SC) kg–1 diet; T2 = 0.8 g SC kg–1 diet; T3 = 1.0 g SC kg–1 diet and T4 = 0.0 g SC kg–1 diet) with 30 birds per treatment and replicated twice with 15 birds per replicate in a completely randomized design. Feed and water were provided ad libitum to the birds in a deep litter system. In the end, data on growth, carcass and organ indices generated from the study were analyzed using one-way analysis of variance (ANOVA). Results showed no significant difference (p > 0.05) among the treatments in the birds’ growth performance indices. However, significant differences (p < 0.05) were observed in the birds’ values for liver weight, heart weight, shank length and thigh length with birds in T3 recording highest values of 61.30 g, 16.93 g and 12.00 cm for liver weight, heart weight and thigh length, respectively. It was thus concluded that finishing broilers fed 1.0 g of S. cerevisiae had superior carcass and organ characteristics than birds on the control and lower levels of inclusion.

Nusa Penida island is one of center for seaweed culture in Bali province. Seaweed that cultured is Euchema spinosum and Euchema cottoni spread around coastal. There also found wild seaweed, such as Ulva sp and Gracillaria sp. Abalone (H. squamata) is one of kind Mollusca which high economic value, but abalone cultured is not yet develop in Nusa Penida island, although this island have high potency for developing abalone culture. Abalone culture needs seaweeds as a diet. The abundance of seaweeds as abalon diet is important for developing abalon culture in Nusa Penida Island in the future. The aim of this research was to asses the potency of seaweeds as diet for developing abalone culture in Nusa Penida island. Research was done in Batununggul village, Nusa Penida Island. Experimental design was used Completely Randomized Design (CRD) with 3 treatments and 3 replications. The treatments were used different seaweeds as diet for abalone culture: (DG=Diet Gracillaria sp, DS=Diet Spinosum sp. and DU=Diet Ulva sp.). Abalon were cultured for 4 months by feeding the diet at satiation. Data analysis was used analysis varian (Anova) with SPSS. 16. The result showed abalon fed with Gracillaria sp (DG) at 4.73 g was the highest growth by 4.73 g, followed DU by 3.93 g and DS by 3.43 g. Meanwhile the abalon shell length fed with Gracillaria sp (DG) was the highest growth by 6.55 mm, followed DU by 5.97 mm and DS by 5.60 mm. Based on variant analysis showed growth performance (length shell and weight) abalon, all treatments were not significantly different (P>0.05). The conclusion this research, the three species of seaweed can be used as diet for abalone culture. These seaweeds have same potency as diet for developing abalone culture in Nusa Penida Island
