Abstract

A study on the use of Zinc bacitracin antibiotic (ZnB) and dried Morinda citrifolia waste as feed additive in broiler ration was conducted. Two hundred and sixteen day old chicks (DOC) was allocated into 4 treatments: control; control + 50 ppm ZnB, and control + M. citrifolia waste at 2 levels (5 and 10 g/kg ration) with 9 replications. Each replicatation consist of 6 birds. The treatments were allocated in a completely randomized design. Variables measured were feed intake, live weight, feed conversion ratio (FCR), percentages of carcass and internal organs (liver, gizard, abdominal fat, and thickness of intestine). The results showed that feed intake of  M. citrifolia waste was significantly (P<0.05) lower than that of control. Live weight and live weight gain of M. citrifolia waste treatments did not significantly different (P>0.05) from that of control. The use of M. citrifolia waste (5 and 10 g/kg) gave significantly lower (P<0.05) live weight than the use of antibiotic. FCR of M. citrifolia waste 5 g/kg ration and antibiotic was not significantly different (P>0.05), but was significantly lower (P<0.05 ) than that of control and M. citrifolia waste 10 g/kg. Carcass and internal organ percentages were not effected by antibiotic and M. citrifolia waste. Liver percentages with M. citrifolia waste 10 g/kg was significantly (P<0.05) higher and abdominal fat was lower (P>0,05) than that of control, control + antibiotic ZnB and M. citrifolia waste 5g/kg. It is concluded that  the supplementation of M. citrifolia waste (5 g/kg) could substitute ZnB to improve feed eficiency in broiler ration. Key Words: M. Citrifolia Waste, Performances, Broiler

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

The experiment has been conducted to determine the nutritive value of palm oil sludge fermented with A. niger added with different sources of phosphorus (NPK, P2O5, NaH2PO4). The experiment was assigned in a factorial (3x3) design. The main factor was sources of phosphorus, while the sub factor was time of incubation (0, 4 days aerobic incubation, and 4 days aerobic incubation followed by 2 days anaerobic incubation). Parameters measured were pH, soluble nitrogen, true protein and crude protein, total α-amino acid (TAAA), soluble phosphorus and total phosphor, in vitro dry matter (DCBK), and true protein digestibilities (DCP). Results from the analyses showed that fermentation increased the contents of soluble and total P, protein and TAAA and the value of in vitro protein digestibility. Fermented product added with P2O5 had the highest in vitro dry matter digestibility, while the one added with NPK had true protein content and digestibility. It was concluded that additional NPK gave the best result interm of nutritive value.   Key words: Palm oil sludge, A. niger, phosphorus sources

Abstract

Research of nutritional evaluation of fermented copra meal and its application in broiler has been conducted. In the first experiment the crude protein and fiber contents were determined in the fermented copra meal using A. niger BPT, NRRL 337 and ES1. Further, 384 of Indian River DOC were used for in vivo experiment. Completed Randomized Design was used with 8 treatments: Control without and with 10% addition of copra meal, 3 levels of fermented copra meal addition with Aspergillus niger BPT or A. niger NRRL 337 (10, 15, 20%). Every treatment was repeated 8 time with 6 birds each. Variables measured were body weight, consumption, feed conversion, mortalities and carcass analyses. Diets were formulated in isocalori and isoprotein. The research was conducted in 6 weeks. The results showed that fermentation process increased the copra meal protein content from 22.3 to 36.1; 35.6 and 38.6% respectively for fermentation with A. niger BPT, NRRL 337 and ES1, decreased the crude fiber from 19.5 to 13.0; 18.9 and 8.28%. Results during 3 weeks trial show that the treatment significantly affected on broiler performance (P<0.05). Fermented copra meal was better than non fermented copra meal. There was no significantly different (P>0.05) in broiler performance at 6 weeks trial evaluation. The best conversion was in diet with 10% fermented copra meal with A. niger BPT and NRRL 337. The feed conversion of diets with 10% of each fermented products were better than control or diet without copra meal. The feed conversion of 15% fermented copra meal addition was not significantly different to control. Utilization of fermented copra meal with A. niger BPT or NRRL 337 should not more than 15%.

Abstract

A development of nanotechnology today has penetrated almost all areas of life. Utilization in improving livestock production can be done by replacing commonly used conventional mineral by nanoparticles-mineral. Application of chromium (Cr), selenium (Se), silver (Ag) and copper (Cu) nanoparticles are reported to improve livestock production. However, the potential risk of the application such as mineral deposit in the body of animal itself and to people as consumers of livestock product has to be evaluated. Nanoparticle-minerals that have smaller size are easier to penetrate the cells and it is suspected that it may give more negative risk. Analysis evaluation of nanoparticle-minerals in the animal including people are still being developed. Key words: Nanoparticle-minerals, Cr, Se, Ag, Cu

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

Utilization of by-product from agriculture as alternative source of feedstuff has been widely practiced. However their usage is limited due to high fiber content and low nutrient digestibility. The use of specific hydrolizing enzymes, xylanases are gaining importance because of their wide application in various industrial sectors especially in bioconversion of hemicellulosic material. This experiment was done to evaluate the effect of cation addition and immobilization of enzyme into pollard on stability of B. pumilus xylanase. The enzyme extract was purified by precipitation with 75% ammonium sulphate. Four kinds of cation (Ca2+, Fe3+, Mg2+, Zn2+) were added to the purified enzyme, at concentration of 1m M and stored at 4 and 27˚C. For immobilization process, the optimum enzyme concentration that will be added to pollard has been evaluated by analysis of xylanase activity and their recovery. The specific activity of enzyme after precipitation increased 1.8 times, from 420.3 to 765.2 U/mg protein. All cations act as activator which relative activity become 130.6; 139.0; 103.8 and 163.5% respectively. Concentration of 0.5mM Ca2+ and Fe3+ were most able to keep xylanases activity stable at 4˚C. The optimum composition of enzymes and pollard was 1.5 ml for 5 gram of pollard with recovery of xylanases activity of 82.2%. In immobilized enzyme, the activity of enzyme without cation addition is higher than that with addition of Ca2+ and Fe3+. Activity of enzyme stored at 4˚C is more stable than that at 27˚C. Immobilized enzyme is more stable for storage, which lasted for 7 weeks at 27˚C and 12 weeks at 4˚C compared to liquid enzyme which lasted for only 7 days at 27˚C and 13 days at 4˚C.

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 conducted to improve the utilization of coconut meal in poultry ration . A bioprocess (fermentation) approach was adopted. Coconut meal was fermented followed by an enzymatic process at room temperature or 50 OC.The nutritive value of the fermented products was determined chemically. Product with the highest nutritive value was then used for a feeding trial to study the interaction effect between dietary levels of fermented coconut meal and phosphorous level on the performances of laying ducks. Nine experimental diets were formulated, i.e ., the factorial of 3 levels of fermented coconut meal (0, 30 and 40%) and 3 levels of total phosphorous (0.6, 0.8 and 1 .0%) . The diet was fed to pullet ducks and the performances of the ducks were observed for 16 weeks of production period. The results showed that the nutritive value of coconut meal increased by fermentation and the highest yield was achieved when the enzymatic process was performed at 500C. There was no significant interaction effect between dietary fermented coconut meal levels and the phosphorous levels on all parameters observed, except on egg weight. Inclusion of fermented coconut meal in the ration up to 30% did not produce negative effects on the productivity oflaying ducks, however, higher levels (40%) ofinclusion reduced the egg size   Keywords: Coconut meal, fermentation, ducks, egg production
