Abstract/ Executive Summary:

The experiment was conducted with 144 broiler chicks from day-old to 5 weeks of age to investigate the efficacy of a water additive in broiler production. The chicks were randomly distributed into four different treatments namely T₁ (control), T₂ (water additive as per recommendation level), T₃ (25% less than recommendation) and T₄ (25% more than recommendation). The bodyweight of control group was higher in 2nd week of age, but at the end of the experiment additive groups showed higher values compare to control (p<0.05). Bodyweight gain was increased and feed conversion ratio was improved in the additives groups during the finishing and total period, although feed intake was different among the additive groups (p<0.05). When the hematological parameters were evaluated, packed cell volume and total erythrocytes counts were increased in the additive group that received 25% more than a recommendation, and hemoglobin in 25% less than the recommendation group. Mean cell volume and mean cell hemoglobin of the additive groups showed lower (p<0.05) values compare to the control, but other parameters were not affected. Sales price and profit were significantly higher in the additive groups compare to the control, although total production cost was increased in the additive groups (p<0.05). All levels of water additive increased profit in comparison with the control but 25% less than the recommendation level appeared to be most profitable and cost-effective. It also suggests that any additive considered for poultry, must undergo trial for determining efficacy as well as its cost-effectiveness for application.

Objectives:

To investigate the effect of an organic water additive lisovit, which containing muramidase, peroxidase, oligosaccharide, vitamin E, vitamin C and plant extract on the productive performances, hematological parameters and cost effectiveness of floor reared commercial broilers.

Methodology:

Broilers and experimental design: The study was conducted with 144 day-old commercial broiler chicks (Cobb 500) for a period of 5 weeks. The chicks were randomly distributed into four different treatment groups namely, T₁ (control), T₂ (water additive as per recommendation level), T₃ (25% less than recommendation), T₄ (25% more than recommendation) with three replications in each treatment. The number of birds in each replication was 12. All birds received a starter diet from 0~3 weeks and a finisher diet from 4~5 weeks. The water additive lisovit consist (per kg) of muramidase (lysozyme, 5X108 SU), peroxidase (120 g), fructooligosaccharide (30 g), herbal extract (390 g), vitamin E (2.5 g) and vitamin C (150 g) (Biomin, Austria). All diets were formulated to meet or exceed the nutrient requirements of broiler chickens (NRC, 1994). Broilers management: The house and necessary equipment were properly cleaned, washed and disinfected, subsequently dried and left them empty for a week before the arrival of chicks. Water additive was properly mixed with fresh, cool and clean drinking water and supplied to the experimental birds once in the morning and again in the afternoon. It was added to drinking water twice in a week at 1st, 3rd and 5th week of age according to manufacturer instruction. Fresh, clean and dried rice husk was used as litter materials at a depth of about 3cm. The litter and housing area were disinfected with a safe and suitable disinfectant in every alternate day. Care was taken to ensure proper ventilation with the advancement of age of birds. The birds were exposed to a continuous lighting of 23 hours and a dark period of 1 hour in 24 hours. They were vaccinated against Gumboro and Newcastle Diseases. Growth performance measurement: The body weight of broilers was measured every week from the initial day to the final day of the experiment to calculate the body weight gain. The feed intake of broilers was recorded by offering a weighed quantity of feed and weighing their residues on a weekly basis. The feed conversion ratio (FCR) was calculated based on amount of feed consumed to the body weight gain of the broilers. Hematological analysis: Five ml of blood was collected from jugular vein from three birds considering randomly from each group and stored in a sterilized test tube containing 0.5 ml anticoagulant sodium citrate (4%) at a ratio of 1:10. The hematological studies were performed within two hours of blood collection. The hematological parameters such as total erythrocyte count (TEC), hemoglobin (Hb), packed cell volume (PCV), erythrocyte sedimentation rate (ESR), mean cell volume (MCV), mean cell hemoglobin concentration (MCHC) and mean cell hemoglobin (MCH) were determined by routine methods as previously described (Jain, 1986). Cost analysis and statistical analysis: Cost analysis was performed considering market price of inputs and outputs. Profitability was determined considering the cost incurred for water additive. Data were analyzed using the general linear models of SAS (2003) to estimate variance components with a completely randomized design. Duncan's multiple comparison tests were used to examine significant differences among the treatment means. The level of significance was set at p<0.05. Data are presented as mean values ± standard error.

Achievement/Findings:

It may be concluded that the productive performances of broilers treated with water additive 25% less or more than recommended levels were higher than control. There was no adverse effect of the test material on hematological parameters of broiler that could affect productivity and profitability. Though addition of additives in water increased the production cost of broiler, return in terms of profitability supports its inclusion, but a level less than 25% of recommended level provides highest profit and therefore most cost-effective. The study also suggests that feed or water additive considered for poultry, must undergo trials to determine efficacy, correct dose as well as its cost-effectiveness.
