The aim of doing this experiment was to observe the growth response of improved native breeds of chicken under diets differed in energy and protein content. Three groups of improved native breeds, obtained from mating of ♂KUB to ♀KUB (Line 1), of ♂SenSi to ♀KUB (Line 2) and of ♂Gaok x ♀KUB (Line 3), were subjected to three experimental diets, differed in metabolizable energy (ME) and crude protein (CP) content. The experimental diets consisted of Diet 1 (2,800 kcal ME/ kg with 17,81% CP), Diet 2 (2,950 kcal ME/ kg with 18,61% CP) and  Diet 3 (3,100 kcal ME/ kg with 19,25% CP). The experiment was designed as factorial 3 x 3 with 7 replications of each treatment combination, consisted of 5 birds per treatment combination. The chickens were raised up to 10 weeks of age. Results of the experiment showed that Line 2 (♂SenSi mated to ♀KUB) had highest body weight at 10 weeks of age (P<0.05), lowest feed conversion ratio (FCR) and highest European Production Efficiency Factor (EPEF), compared to other two lines. The appropriate diet for Line 2 was Diet 2. It could be concluded the crossbred line that was resulted from crossing of ♂SenSi to ♀KUB (Line 2), had potential to be used as improved native chicken for the industry in Indonesia supported by appropriate diet containing 2,950 kcal ME/kg with 18.61% crude protein.

SummaryAbout sixty male lambs were fed ad libitum from 6 weeks of age on low- or highprotein diets based on barley or barley and fishmeal and containing respectively 120 and 200 g crude protein/kg dry matter. Some lambs were changed from one diet to the other when they reached 28 kg live weight. All were slaughtered as they attained a predetermined series of live weights ranging from 20 to 75 kg.Throughout the experiment, rates of live-weight gain were substantially higher with the high-protein (HP) than with the low-protein (LP) diet, but were highest after a change from low to high protein (LHP). The feed consumption of the LHP lambs did not exceed that of the HP lambs, but the former showed a substantial superiority in feed conversion ratio at the same live weight.At similar empty body weights, the LP lambs contained more fat and less water in the empty body than the HP lambs. Although the percentage differences decreased at higher weights, differences were still apparent at 70 kg live weight.The LHP lambs showed dramatic and rapid changes in body composition, particularly in water and fat content. By 40 kg live weight, their composition approached that of the HP lambs.The ratio of water to protein was consistently lower for the LP lambs. The ratio of protein to ash also differed between LP and HP lambs. It was initially highest for the HP lambs, at about 40 kg live weight it was the same, and at 70 kg live weight it was highest for the LP lambs.The ash content of the LHP lambs remained virtually constant during the period of rapid growth and rapid deposition of water, protein and fat which took place immediately after the change of diet, and only showed compensatory increases after 35 kg live weight. This finding was supported by the pattern of changes in weight and specific gravity of the femur and tibia + fibula.Use was made of separate relationships between live weight and body composition for the LP, HP and LHP lambs to estimate rates of accretion of crude protein, fat and water in the empty body. There was a particularly striking increase in the rate of accretion of water immediately following the change of diet. There was an increase in the water content of empty-body gain and a reduction in the ratio of gain in fat to gain in protein.Derived estimates of the ratio of metabolizable energy intake above maintenance to the energy content of empty-body gain gave some suggestion of an improvement in efficiency of utilization of metabolizable energy for gain following the change from low to high protein. It is concluded however that the improvement in food conversion ratio following the change is attributable mostly to difference in the composition of gain.

The study was designed to investigate the comparative anti-coccidial efficacy of ZeeCox® (Phytogenic anti-coccidial formulation developed by Indian Herbs Specialities Ltd) at recommended dose levels, with commonly used ionophore anti-coccidial drugs such as salinomycin, lasolacid and anti-coccidial vaccine. A total of 324, day-old broiler chicks were reared under standard management practices. The chicks were randomly divided into nine groups with each group consisting of 36 birds. Body weight gain, Feed Conversion Ratio, intestine lesion score, oocyst per gram feces and European Performance Efficiency Factor (EPEF) of all experimental group birds were measured. All the chicks except Group 1 were inoculated orally with the total of 20,000 live sporulated oocysts of Eimeria species on 18th day of age. The overall performance such as Body weight gain, Feed Conversion Ratio and European Production Efficiency Factor (EPEF) of Group 5 (ZeeCox® 0.5g/kg treatment and Challenged) was better and comparable with Group 3 (Salinomycin treatment and Challenged) and Group 4 (Salinomycin & Lasalocid treatment and Challenged). It was concluded from the present study that ZeeCox® at 0.5g/kg of feed could be a potential alternative to the ionophore anticoccidial drugs used in the control of coccidiosis in broiler chicken.

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.

Background: Soybean milk by-product (SMBP) is a potential alternative feed ingredient in swine diets due to its high protein content. However, information on energy and nutritional values of SMBP used as swine feed ingredient is limited. Objective: To estimate energy values and protein digestibility of SMBP in pigs based on in vitro assays. Methods: Four SMBP samples were obtained from 3 soybean milk-producing facilities. In vitro total tract disappearance (IVTTD) and in vitro ileal disappearance (IVID) of dry matter (DM) in the SMBP samples were determined. In vitro ileal disappearance of crude protein was determined by analyzing crude protein content in undigested residues after determining IVID of DM. Digestible and metabolizable energy of SMBP were estimated using gross energy, IVTTD of DM, and prediction equations. Results: Sample 4 had greater IVTTD of DM than that of sample 3 (97.7 vs. 94.4%, p<0.05), whereas IVID of DM in sample 4 was lower compared with sample 1 (53.5 vs. 65.0%, p<0.05). In vitro ileal disappearance of crude protein in sample 2 was greater than that in sample 1 and 3 (92.6 vs. 90.6 and 90.1%; p<0.05). The estimated metabolizable energy of SMBP ranged from 4,311 to 4,619 kcal/kg as-is basis and the value of sample 3 was the least (p<0.05) among SMBP samples. Conclusion: Energy values and protein digestibility should be determined before using SMBP in swine diets.

Abstract The purpose of the study was to obtain preliminary data on the effect of dietary protein on the growth of the thick-lipped grey mullet (Chelon labrosus) juveniles reared in net sea-cages. The juveniles (6.2 ± 0.61 g) were obtained from the wild and were stocked into net sea-cages at a stocking rate of 100 juveniles per cubic meter and fed with experimental diets including 25, 30, or 35% crude protein for 87 days. The highest mean weight and specific growth rate (SGR) were 39.5 g and 2.13% day−1, respectively, at protein levels of 30%. The diet also resulted in the most efficient feed conversion ratio of 1.61.

The development of free-range chicken farm is constrained by expensive food prices. On the other hand,feses of cattle had potential use as a source of feed. This study was conducted to determine the response ofcow feses and probiotics administration in the diet of laying range chicken. The study was conducted over 6months using 240 free-range chickens aged 8 months. Research was arranged in a completely randomized designwith 8 treatments and 5 replications. The treatment given were ration in accordance with the farmers formulacomprising: concentrate: 25%, corn 40% and rice bran 35% (P0) and ration as P0, with the substitution of ricebran with fermented cow feses each treatment with level 10 % (P1), 15% (P2) and 20% (P3) and ration as atP0, P1, P2 and P3 that received additional probiotic (Bio L) 1 cc / L of drinking water (P4, P5, P6 and P7). Theparameters were observed are: egg production (hen day), egg weight, feed intake, FCR (Feed Conversion Ratio)mortality and physical composition of eggs. The results showed that the diet which containing fermented cowfeses 20% did not decreased egg production and feed efficiency. The combination of fermented cow feses at thelevel of 20% with a probiotic (Bio L) 1 cc / L of drinking water showed that egg production  increased althoughit is not significant and reduce the number of FCR (Feed Conversion Ratio). In conclusion the use of fermentedcow feses up to the level of 20% in the diet both with and without the administration of probiotics, has no effecton physical composition of eggs.
