The purpose of this study was to find the effect combination probiotic Lactococccus lactis and Lactobacillus casei on the laying hens infected with bacteria Escherichia coli on feed consumption and feed conversion ratio (FCR). The materials used in this experiment were 120 laying hens aged 25 weeks. Feeds were used commercial concentrate produced by PT. New Hope East Java, type 7183A. In this study were added of six treatments that is (a0b0) chicken without infection and without treatment, (a0b1) chicken without infection plus Antibiotic Growth Promoter (AGP), (a0b2) chicken without infection plus probiotic, (a1b0) chicken infection without treatment, (a1b1) chicken infection plus AGP. (a1b2) chicken infection plus probiotic. Each treatment was repeated four times. The variables measured were are feed consumption (g/bird/day) and feed conversion ratio (%). Data were analyzed statistically using Analysis of Variance (ANOVA), if between treatment showed significant effect were analysed by Duncan’s Multiple Range Test (DMRT). The result of this research shows that the use of probiotic Lactococccus lactis and Lactobacillus casei on the laying hens infected with bacteria Escherichia coli give a real distinction ( P<0,05) towards feed consumption and showed a real distinction (P <0.05) towards feed conversion ratio. Based on the results of this research, it can be concluded that the addition of probiotic Lactococccus lactis and Lactobacillus casei on the laying hens infected with bacteria Escherichia coli can improve feed consumption, feed conversion ratio (FCR) of laying hens, hen day production (HDP) and egg weight.

This experiment studied the effects of perches in furnished cages on behaviour and feed consumption of laying hens. The study used 352 Lohmann Selected Leghorn (LSL) hens. The hens were housed at 16 weeks of age in furnished cages in groups of 8 birds. The experiment lasted for 205 days. The treatments were: perches present from 16 weeks of age (P16), perches present from 19 weeks of age (P19), and no perches present (NP). Feed consumption and egg production were measured over the pre-laying period and six 4-week laying periods. The number of hens on perch, in nest and litter box was recorded at various ages. The behaviour of 3 hens per treatment was observed using instantaneous sampling at every 5 minutes, so that the observations of each hen covered one light period (14.5 hours). The treatments had no significant effects on feed consumption after the pre-laying period. Feed conversion ratio (kg feed kg-1 eggs) was favourable in P16 in comparison to NP during the periods 2–4. During the observations after the lights-out NP birds tended to be more frequently in nests, than P16 birds. NP birds spent more time on the cage floor, were recumbent more often, and sitting more rarely in comparison to P16 birds. Based on the results of this study, perches may have advantageous effect on feed conversion ratio in furnished cages.;

Development of poultry has been done in terms of breeding, feeding and management. However, the implementation still faces many challenges such as the problem of production decrease. One cause of the decline in production is a health disorder caused by pathogenic bacteria (Salmonella sp and Escherichia coli). One way to overcome the problem is the use of Piper bettle linn Juice as a feed additive. The purpose of this study is to determine the effect of Piper bettle linn Juice as a feed additive to the performance of laying hens. The method used is the biological test of laying hens age 69 weeks of Isa Brown Strain of 250 laying hens, using Completely Randomized Design (RAL) with 5 treatments and 5 replications. The results of the research showed that Piper bettle linn Juice gave no significant effect (P> 0,05) to feed consumption and mortality. Influence significantly (P<0,01) to Hen Day Production (HDP), egg weight and Feed Conversion Ratio (FCR).

This study was conducted to examine the effect of Hemicell® addition on diets containing different levels of crude fiber on performance and egg quality of laying hens. A total of 72 laying hens aged 21 weeks were randomly divided into 18 experimental units. A completely randomized design with factorial design 2×3 and 3 replications was employed in this study. Factor A was crude fiber level (5% and 8%) and factor B was the level of Hemicell®(0, 100x103 and 200x103 IU/kg ration).  Results showed that crude fiber significantly (P<0.01) increased feed consumption and decreased the performance of laying hens. The addition of Hemicell®in diets significantly (P<0.01) decreased feed consumption and increased the performance of laying hens. Hemicell®addition (100 IU) to a diet containing 8% crude fiber significantly (P<0.05) affected egg mass, feed conversion ratio, egg yolk score and egg weight. It can be concluded that diet with 8% crude fiber added with Hemicell® (100 IU) could increase egg mass, feed conversion ratio, egg weight and yolk color score.

The study was conducted to evaluate an appropriate inclusion level of locally produced unprocessed or expander-processed coloured flowered faba bean (FB) (cv. ‘Kontu’) seeds in diets for laying hens. Egg production and egg quality variables were determined with 560 hens (Lohmann Selected Leghorn, LSL Classic) in a 40-week continued experiment. The hens were fed one of the five diets containing soybean meal as the main protein source. A diet without FB was served as a control diet. Both unprocessed and expander-processed FB was tested either in proportions of 50 g kg-1 or 100 g kg-1 in the diet. Faba bean inclusion (control vs. FB diets) had no effect on the egg production rate, egg mass production, feed consumption, or feed conversion ratio, but it decreased egg weight (p<0.05). Dietary FB inclusion tended to increase the mortality of the hens (p<0.10). Faba bean processing had no effects on egg production parameters or hen mortality. Daily egg mass production decreased and feed conversion ratio increased when FB proportion increased (from 50 to 100 g kg-1, p<0.05). Faba bean inclusion had no effects on egg exterior quality. It can be concluded that 50 g kg-1 of the FB studied (cv. ‘Kontu’) can be used in the diets of laying hens (LSL Classic) without negative effects on production performance or livability.

Colibacillosis in Indonesia until now still appears frequently, so the case of colibacillosis laying hens cannot reach the peak of egg production; the egg production period is delayed and easily infected with other diseases. The purpose of this research is that the acidifier-dextrose combination is expected to be able to suppress the development of Avian Pathogenic Escherichia coli (APEC) bacteria in laying hens so that, in the end, the case of colibacillosis can be controlled in Indonesia. A total of 240 heads of laying hens were divided into 6 treatments and each consisted of 40 replications. The results of this research state that a combination of acidifier-dextrose can increase Hen Day Production ( p < 0.05 ) and decrease Feed Conversion Ratio ( p < 0.05 ) in laying hens infected with APEC. The Hen Day Production results of the treatment group infected with APEC showed the lowest results, amounting to 65.75% whereas the other treatments are still above 90%. Furthermore, the highest Feed Conversion Ratio results were on treatments infected with APEC, which amounted to 2.17 while other treatments of the Feed Conversion Ratio results are still below 1.80. In general, the use of a combination of acidifier and dextrose with the lowest dose, that is, 1 g/3.75 liters of drinking water can still give good results to Hen Day Production and Feed Conversion Ratio for laying hens infected with APEC. Giving combination of acidifier-dextrose can increase Hen Day Production and decrease Feed Conversion Ratio in laying hens infected with APEC. The recommended dosage of acidifier-dextrose combination in laying hens based on this research is 1 g/3.75 liters of drinking water.

Abstract. This study was carried out to investigate the effects of fluctuate lighting on performance of laying hens. Two programs were applied with 16 hours daily lighting: step-up (normal) lighting program as the control treatment and a fluctuate lighting program of 2 W/m2 for 45 min and 6 W/m2 for 15 min. Egg weight, feed consumption, feed conversion ratio, henday egg production and hen-housed egg production of the laying hens were recorded for 46 weeks. No significant difference for hen-day and hen-housed egg production between the step up and fluctuate lighting programs (P>0.05) were found. However, fluctuate lighting program resulted in a significant increase in egg weight (P<0.05). Moreover, hens in the fluctuate lighting program consumed significantly less amount of feed and had a better feed conversion ratio than hens in the step-up lighting program (P<0.01). The results of the present study indicate that fluctuate lighting can be used for a profitable egg production.

Background and Objectives: Use of antibiotics as growth promoters in animal feeds has been restricted due to the residues in poultry products such as egg and meat, furthermore to the antibiotic resistant of pathogenic bacteria. The prohibition of their use opens the opportunity for the use of non-antibiotic feed additives such as probiotics. The objectives of this study were to investigate the effect of the addition of  Lactobacillus casei WB 315 and crude fish oil (CFO) to diets on growth performance, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), low density lipoproteins (LDL), high density lipoprotein (HDL), and cholesterol levesl of  broiler chickens. Materials and Methods: In this research, one-day old male broiler chicks were used and divided equally into four groups, namely a basal diet without L. casei WB 315 and without CFO (P0), basal diet supplemented with 0.5% L. casei WB 315 of total broiler basal feed (1.2 × 109 cfu/ml) and without CFO (P1), basal diet supplemented without L. casei WB 315 and 1% CFO of total broiler basal feed (P2), and basal diet supplemented with 0.5% L. casei WB 315 of total broiler basal feed (1.2 × 109 cfu/ml) and 1% CFO of total broiler basal feed (P3) for 35 days. Results: The results of addition 0.5% Lactobacillus casei WB 315 (1.2 × 109 cfu/ml) and 1% CFO of total broiler basal feed after 35 days showed significant difference among treatment in feed efficiency (p<0.05), feed conversion ratio (p<0.05), feed consumption (p<0.05), EPA (p<0.05), DHA (p<0.05), increase HDL (p<0.05), reduced the LDL (p<0.05), and reduce cholesterol (p<0.05) in meat broiler chicken. Conclusion: It is concluded that the addition of L. casei WB 315 and crude fish oil (CFO) could significant improve the growth performance (feed efficiency, feed conversion ratio, feed consumption) and could significantly improve EPA, DHA and increase HDL and decrease LDL in meat poultry product.

This article describes a new idea about using Bifidobacteriumsp isolates as an alternative to antibiotic growth promoters, based on the ability of Bifidobacteriumsp isolates, which have the potential as a probiotic in laying hens. This study aims to prove that Bifobacteriumsp could improve production performance, including feed conversion ratio, feed efficiency, and nutrient intake (feed intake, crude protein intake, crude fiber intake, lipid intake, and organic matter). A total of 150 laying hens at 25 weeks of age were divided into three groups (P0: control, P1: 0.1% antibiotic growth promoters, P1: 0.05% Bifidobacterium spp. probiotic) and fed on a basal diet containing 2750 kcal/kg metabolizable energy and 18% crude protein for four weeks. The different supplementation to the basal diets showed significant differences (p<0.05) on feed conversion ratio, feed efficiency, feed intake, crude protein intake, crude fiber intake, lipid intake, and organic matter intake among the treatments. However, feed intake, feed conversion ratio, crude protein intake, crude fiber intake, lipid intake, and organic matter intake were lowest in the group fed with 0.5% of Bifidobacterium spp. The highest feed efficiency was obtained from the groups fed with 0.5% of Bifidobacterium spp, compared with the control and supplemented antibiotics growth promoters group. 0.5% of Bifidobacterium spp. supplementation to the diet of laying hens is beneficial for increasing feed efficiency and improving feed conversion ratio. The practical and theoretical significance of the results is that Bifidobacterium spp. can be used to improve production performance in laying hens.
