Abstract

The research was aimed to evaluate the effects of substitution level of corn with palm kernel meal (PKM) untreated and palm kernel meal (PKM) treated by enzyme on production performance and carcass quality of broilers. The method used in this research was experiment using nested of completely randomized design with 2 factors, the main factor was type of palm kernel meal factors consisting of PKM without enzyme (B1) and PKM by mannanase enzyme (B2), and substitution corn level L0 (without substitution), L1 (12.5%), L2 (25%), L3 (37.5%) and L4 (50%). The different among the treatments were tested by Duncan’s multiple range test. The results showed that corn substitution with PKM untreated and PKM treated by enzymes was significantly effect (P<0.01) on feed conversion ratio (FCR), tenderness, meat cholesterol of broilers and income over feed cost (IOFC) and significant effect (P<0.05) on feed intake, but there is no significant difference on body weight, percentages of abdominal fat and water holding capacity (WHC). Furthermore, effect of level corn substitition with PKM nested to PKM untreated and PKM treated by enzyme was significantly effect (P<0.01) on feed intake, body weight, FCR, and tenderness and significant effect (P<0.05) on IOFC, but there is no effect on percentages of abdominal fat, WHC and meat cholesterol. It can be concluded that the corn substitution with PKM treated by enzymes was better than the PKM untreated on production performance and carcass quality of broilers. The optimal level of PKM untreated as corn substitution was 12.5%. While replacement with PKM treated by enzyme can be used up to 25%.

Abstract

This research aimed to observe the interaction of methionine-cysteine amino acid supplementation to decrease the effect of aflatoxin B1 (AFB1) on diet against production performance of broiler chicken. A number of 240 mixed sex broiler chickens were treated in 9 treatments by factorial design 3 x 3 with methionine-cysteine amino acid (M+C) (75,100, dan 125%) factors and AFB1 levels (0, 200, dan 400 ppb). Variables observed were: Weight gain, feed consumption, and feed conversion ratio (FCR). The results showed that increased AFB1 content in diet from 0 to 400 ppb increased chicken body weight (P <0.05) in each age group. The high body weight was balanced with high feed consumption along with increased nutrient needs, mainly sulfuric amino acid (M+C) as the precursor of glutathione to eliminate toxic through conjugation reactions. The interaction effect was firstly occurred between M + C and AFB1 treatment (P <0.05). Meanwhile increased supplementation of M + C from 75 to 125% caused decreased feed consumption in each age group of chickens, but increased AFB1 levels further increased feed consumption (P<0.05). The interaction effect between the level of M + C and AFB1 contamination in diets on feed consumption were seen in 21-day-old chickens (P<0.05). FCR was also increased (P <0.05) with the reduction of M + C content in diet at 7 days old. The effect of AFB1 on diet and interaction between M + C and AFB1 on chicken FCR in this study was not significant in all age groups. It can be concluded from the current study that supplying methionine-cystine amino acid with 75, 100 and 125% in AFB1 contaminated diet of 0, 200 and 400 ppb improves the performance of broiler chicken production.

This research used 2 treatments: frozen and fresh milk. Preliminary tests carried out before the transport process, while the final tests carried out after transportation including parameters of chemical composition, physical quality and organoleptic quality. Data were analyzed by statistic t-test. The results showed that the physical, chemical and organoleptic attributes (except viscosity) of frozen and fresh milk were not significantly different before and after transportation. The viscosity of frozen milk before and after transportation were 1.0212 and 1.0277 g/cm3 respectively, while on fresh milk were 1.0265 and 1.0272 g/cm3, respectively. The freezing point of milk before and after transportation was -0.445 to -0.527ºC for frozen milk and -0.480 ºC to 0.490ºC for fresh milk. Protein content before and after transportation was 2.52% to2.78% for frozen milk and from 2.78 % to 2.87% for fresh milk. The fat content before and after transportation was 6.78% to 5.04% for frozen milk and from 3.73% to 4.04% for fresh milk. The lactose content before and after transportation that is from 13.66% become 13.21% for frozen milk and 11.33% to 11.88% for fresh milk. The total solid content before and after transportation was 13.66 % and 13.21% for frozen milk and 11.33% to 11.88% for fresh milk. The SNF content before and after transportation was 6.88 % to 8.17 % for frozen milk and from 7.60% to 7.84% for fresh milk. It can be concluded that traditional transportation of milk from Peternakan Sapi Terpadu to Samarinda did not affect the organoleptic, physical, and chemical except viscosity of milk.

Abstract

This study aimed to determine the effect of water hyacinth addition to farm waste on the number of earthworms, earthworm weight, media shrinkage, vermicompost quality, and the sustainability and sensitivity of earthworm farming. The study was prepared using a completely randomized design with two different factors, the water hyacinth (media without water hyacinth and media with 5% water hyacinth addition) and raw materials from farm waste (chicken and cow manure, and biogas sludge from chicken and cow manure), with three replications for each treatment. The results showed that the addition of water hyacinth to raw materials from farm waste had a very significant effect on the number of earthworms, earthworm weight, media shrinkage, vermicompost quality (except for P2O5 level that had no significant increase). When manure is to be added to the cultivation media, it is recommended to use cow manure, while both types of biogas sludge (from chicken and cow manure) are good for the cultivation of earthworm. Based on the study of sustainability, the use of farm waste and water hyacinth as media to raise earthworm gives a positive value in economic and environmental aspects. Therefore, it has great potential.
