Abstract

The experiment was conducted to evaluate chemical characteristics and biological value of protein concentrate extracted from palm kernel meal (PKM) using combination of physical and chemical extraction. The best method of extraction in term of total amino acid (TAA), essential amino acid (EAA), essential amino acid index (EAAI), and protein recovery then was used for protein retention evaluation using 20 heads of male quails age 30 days. The animals were randomly assigned to one of three dietary treatments, while the remaining quails were used to measure endogenous protein. The treatments were; R1=diet containing 9% crude protein from the best protein concentrate from PKM, R2=diet containing 9% crude protein from PKM and R3=diet containing 9% crude protein from soybean meal). The results showed that protein of PKM had isoelectric pH in a range of 4.3-4.4. Protein concentrate of PKM produced by grinding using 0.05 N acetic acid followed by soaking 1 N technical-NaOH had the highest protein quality compared with those of the other treatments. TAA, EAA, EAAI amount of precipitate and protein recovery of the protein concentrate were 33.38%, 16.76%, 62.41%, 12.18% and 50.38%, respectively. Protein retention of quails fed R1 was not different compared to that of R3 (69,82 vs 70,57%), while quails received R2 had the lowest protein retention value (61,19%). It is concluded that combination methods of physical and chemical extraction using 0.05 N acetic acid followed by soaking with 1 N technical NaOH (E3) was the best method in producing high quality of protein concentrate, and the product had similar protein retention value as that of soybean meal.

Abstract

A study on the use of aloe vera bioactives as feed additive in layer ration was conducted. One hundred and twenty pullets strain Isa Brown were allocated into 5 treatments with 6 replicates and 4 birds/replicate. The treatments were: control,control+antibiotic (50 ppm zinc bacitracin), and control+ aloe vera at three levels (0.25; 0.50 and 1.00 g/kg). The treatments were conducted in a completely randomized design. Parameter measured were first initial body weight, age at 1st lay, feed intake, egg weight, hen day (%HD) and feed conversion ratio. The results showed that antibiotic and aloe vera used as additive for 9 months production did not significantly (P<0.05) affect all parameter measured, except feed intake of hens fed diet containing 0.5 g/kg aloe vera was significantly (P<0.05) higher than control. The addition of aloe vera at 1.0 g/kg significantly (P<0.05) reduced the feed intake as compared with the control, aloe vera 0.25 and 0.50 g/kg. The used of aloe vera (1.00 g/kg) produced egg weight significantly (P<0.05) higher than the control, and feed conversion ratio was significantly (P<0.05) better than the control and aloe vera (0.25 g/kg). It is concluded that the best treatment was the diet with aloe vera level at 1.00 g/kg. This treatment improved feed efficiency 8.40%.     Key Words: Bioactive, Egg Production, Layer

Abstract

feed. Two hundred and ten, day-old broiler chicks were used for this study. They were allotted to 6 different diets containing either BIS or FBIS at 3 different levels (5, 10 and 15%) and one control diet. The results showed that 5% BIS and 5% FBIS could be used in broiler diet without adversely affecting feed intake, weight gain and feed conversion ratio. FCR of those diets were significantly (P<0.05) better than the control diet. Carcass yields were not significantly affected by feeding of BIS nor FBIS. The FBIS diet produced less abdominal fat than the BIS diet.   Key words : Palm kernel cake, fermentation, broilers

Abstract

Feed additives are commonly added in poultry feed as a growth promotant or to improve feed efficiency. The most common feed additive used is antibiotic at sub-therapheutic doses, although there is a controversy on its impact on human health. Previous results showed that Aloe vera gel could improve feed efficiency in broilers and an in vitro study showed that the extract have an antibacterial effect. Therefore, a further experiment was designed to study the response of broilers to Aloe vera gel or its extract as feed additives. Aloe vera was prepared in dry gel or chloroform-extract and included in the diet at levels of 0.25; 0.50 and 1.00 g/kg (equal to dry gel). Standard diets with or without antibiotic were also formulated as control and a commercial diet was included for comparison. The diets were fed to broilers from day old to 5 weeks. Each treatment has 9 replicates and 6chicks/replicate. Parameters observed were: feed consumption, weight gain and feed convertion ratios. Carcass yield, abdominal fat levels, relative weight of liver, gizzard, tractus digestivus and length of tractus digestivus were also measured at the end of feeding trial. The results showed that Aloe gel and its extract did not influence body weight gain and feed consumption of broilers significantly (P>0.05), but improved feed convertion slightly (3.50%). The response in this trial was similar as thosecommercial diet and diet added with antibiotic. There was no significant (P>0.05) effect of Aloe vera bioactives on carcass yield, abdominal fat level and relative weight of liver. However, Aloe vera gel and its extract tend to increase gizzard weight, gastro intestinal weight and length. The Aloe vera gel and its extract also reduced the total count of aerobic bacteria in the digesta of tractus digestivus. It is concluded that the Aloe vera gel improve feed efficiency in broilers by increasing the size of tractus digestivus and reducing the total count of aerobic bacteria in the gastro intestinal tract.   Key words: Aloe vera, feed additives, broilers, anti-bacteria

Abstract

Fermentation processes increase the protein of palm oil sludge and produce some useful enzymes. However, drying process, especially with heating often affects the nutritive values of feed ingredients and the enzymes activity. Therefore, this experiment was designed to study the responses of native chickens when fed ration containing fresh or dried fermented palm oil sludge (FPOS). Experimental diets with different levels of fresh or dried FPOS (5, 10 and 15% equal to dried FPOS) were formulated with similar nutrient contents. A control diet with no FPOS was also included. Each treatment was replicated 5 times for 12 weeks. Performances (body weight, feed consumption, feed conversion and mortality) of chickens were recorded. Carcass yield, abdominal fat content, weight of liver and gizzard were measured at the end of feeding trial. Data were subjected to analysis of variance and different between means were tested by orthogonal procedures. Results during the starting period showed that, chickens fed FPOS diet gain more weight significantly than the control birds (298.1 vs. 264.7). The dry matter intake of the dry FPOS diet was significantly better than the fresh FPOS diet (2.88 vs. 3.32). The FPOS dietary levels did not affect body weight gain and dry matter intake of native chickens, significantly. However, increasing the FPOS levels worsen the dry matter conversion (DCR) significantly. Data during 12 weeks trial showed mat the body weight gain was not significantly affected by treatments. The dry matter intake of the FPOS diets were significantly higher than the control diet (3469 vs. 3065 g/bird), hence the DCR of the control diet was significantly better than the FPOS diets (3.28 vs. 3.62). Feeding dry FPOS resulted in a better DCR as compared to fresh FPOS (3.48 vs. 3.76), but not affected the dry matter intake. The FPOS dietary levels did not affect body weight gain and dry matter intake of native chickens, significantly. However, inclusion of 5% FPOS in me diet gave better DCR significantly, as compared with 15% FPOS (3.51 vs. 3.83). Feeding dry or fresh FPOS (5 - 15%) did not significantly affect the mortality, carcass yield, abdominal fat levels, weight of liver and weight of gizzard of native chickens. It is concluded that dry FPOS was better than the fresh FPOS and could be included in me native chickens diet up to 10%.   Key words: Palm oil sludge, fermentation, native chickens

Abstract

An experiment was conducted to study the response of broilers on the diet containing fermented palm oil sludge with Aspergillus niger stored at different length of time. The research was carried out in Research Institute for Animal Production Ciawi, Bogor. The experiment was conducted based on completely randomized design using 245 day old broiler chicks with 5 replicates. They were allotted to 7 diets containing one control without palm oil sludge (R0), 5 and 10% of fresh-fermented palm oil sludge (LSF) (R1 and R2), 5 and 10% of LSF stored at room temperature for 2 months (R3 and R4) and stored for 3 months (R5 and R6). Diets were fed ad libitum for 5 weeks. Feed intake, weight gain, feed conversion ratio, and carcass yields were observed as parameters. Results showed that no parameters were significantly affected by the treatments. It is concluded that 10% of fermented palm oil sludge could be included in diet of broilers even after three months storage at room temperature.   Key words: Broiler, fermented palm oil sludge, storage period

Abstract

Semi liquid Aloe gel (LBSC) was preserved using sodium chloride (1, 2 and 3%) and sugar (10, 20 and 30%) for 7 weeks at 4ºC. Physical observations (color, odor and gas) and chemical analysis (total phenolic and emodin) were performed every week during preservation. Changing color was observed at the fourth week and until the seventh week. The total phenolic content decreased by 23.2, 12.9 and 19.0% in LBSC with 1, 2 and 3% salt respectively. The total phenolic content in LBSC with 10, 20 and 30% sugar decreased by 64.0, 53.8 and 30.4% respectively. The emodin content decreased by 60.7% for control (LBSC alone), but in LBSC with 1, 2 and 3% salt it was decreased by 26.2, 19.2 and 50.8% respectively. The emodin content in LBSC with 10, 20 and 30% sugar decreased by 70.5, 67.4 dan 82.4% respectively. Emodin was more unstable than total phenolic. Preservation using sugar was not preserve the availability of emodin, while salt could inhibit the decrease of emodin concentration in LBSC. Preservation of LBSC with 2% table salt gave the lowest decrease of emodin and total phenolic contentsKey words: Aloe vera, fenol, emodin, preservation

Abstract

The morphological discriminant and canonical analyses were carried out to determine the genetic distance and discriminant variables between Indonesian breeds of thin tail sheep from Deli Serdang (North Sumatera), Ciamis and Garut (West Java) and fat tail sheep from Garahan and Pamekasan (East Java). The number of sheep randomly collected from farmers was 665 heads, while that from breeding station was 183 heads. Zoometrical variables studied were body weight, body length, wither height, chest depth, chest circumference, hip height, hip depth, hip circumference, tail length, tail width and tail thickness. SAS package program was used to analyze the data. Results from distribution mapping produced by canonical analysis and Mahalanobis distance (phenogram tree) showed that breeds are divided into two groups. The first group is thin tail sheep which consists of Ciamis, Garut and Sumatera, and the other is fat tail sheep which consists of Garahan and Pamekasan. The groups of Ciami and Garut were mixed by Garahan with 1.01 and 1.20%, respectively but were not contaminated by Pamekasan (0.00%). The highest similarity between individual inside the group was obtained from Sumatera (84.27%) due to the isolated flock. It was mixed more by Ciamis (7.87%) and Garut (5.62%) than Garahan (1.69%) and Pamekasan (0.50%). Results from canonical analysis also showed that body length, chest circumference, hip circumference, and body weight was less discriminant variables to determine the differences between breeds, while the most discriminant variables were obtained by tail length, tail width and tailthickness.   Key words : Sheep, genetic distance, morphology

Abstract

A trial was conducted to determine the effect of various level of cassapro (fermented cassava) and halquinol supplementation on the performance of broiler chickens . Experimental rations were formulated isoprotein and isoenergy with graded level of cassapro (0, 10, 20 and 30%) . The 20 and 30% cassapro ration were prepared without and with halquinol supplementation (60 ppm). Each ration was fed to 40 of three day old broilers, divided into 4 cages ( 5 males and 5 females per cage) for 4 weeks. Increasing the level of cassapro significantly reduced body weight gain (P < 0.005), increased feed conversion ratio (FCR) (P < 0.0005) with no effect on feed intake (P < 0.10) . Halquinol supplementation has no effect on feed intake, but significantly increased body weight gain (P <0.05) and improved the FCR (P < 0.01) . It is concluded that high level of cassapro in the ration will cause poorer performance of the birds, however it can be alleviated by halquinolsupplementation.   Keywords: Broiler, cassapro, halquinol

Abstract

A series of experiment was carried out to evaluate the use of palm kernel meal and its fermented product in the ration of growing ducks. Treatments were arranged in a 2x3 factorial experiment, i.e. the combination between two processes (unfermented and fermented palm kernel meal) and three levels of ingredients in the diet (5, 10 and 15%). Four replicates were applied for each treatment, with 8 ducklings in each replicate. A control diet with no palm kernel meal was also formulated. All diets were formulated to have a similar protein and ME contents. Results of the experiment showed that fermentation process increased the nutrient composition (crude protein, true protein, phosphorus, and the metabolizable energy) and reduced its fibre and fat content. The feeding trial showed that neither the fermentation process, levels of ingredients nor the interactions of the two factors affected final body weight, feed consumption, feed conversion, carcass percentage and abdominal fat of the ducklings significantly. It is concluded that fermentation process improved the nutritional value of palm kernel meal and the inclusion of palm kernel meal (unfermented and fermented), up to 15% in the diet of ducks did not negatively affect the growthperformance and the carcass yield.   Key words : Ducks, palm kernel meal, fermentation
