The effect of water-soluble blood meal was tested on the performance of broilers. Forty broiler chickens aged 21 days were reared on slatted floor and the dietary treatments were T0, T1, T2 and T3 where 0, 0.25, 0.50 and 0.75 g blood meal was given/L drinking water, respectively. The blood meal significantly enhanced the growth and feed conversion efficiency. The weight gain and net profit was significantly (p<0.001) higher in chickens with 0.25g/L blood meal in water. It is suggested that blood meal at 0.25g/L may be used in drinking water during growing and finishing period of broilers for better performance. DOI: 10.3329/bvet.v26i1.4625 Bangl. vet. 2009.

An experiment was conducted to determine the influence of an acidifier as an alternative to antibiotics on the performance and gut morphology of broiler chickens. One hundred and eighty (180) 7-day old broiler chicks were randomly assigned to 3 dietary treatments of 4 replicates each. Each replicate had 15 birds. The diets fed to the birds were: Treatment 1- diet with neither antibiotic nor acidifier; Treatment 2- diet with antibiotic and Treatment 3- diet with acidifier. The antibiotic used was Enrofloxacin which was administered to the birds on Treatment 2 via their drinking water while the acidifier used was Biotronic SE (a combination of propionic and formic acids) which was added to the diet of birds on Treatment 3 at the rate of 4kg/tonne of feed. The experiment lasted 42 days. No significant differences were observed in the feed intake, final weight and weight gain of the birds on the different diets. Significant differences were however observed in the villus height in the duodenum and ileum of the birds. The crypt depth values in the different segments of the small intestines of the birds were not significantly affected by the different treatments.Key words: Organic acids, Biotronic SE, Enrofloxacin, Crypt, villus.

The present study was conducted to determine the effect of silicon oxide in broiler chickens drinking water on performance and litter quality. A total of 120, one-day old mixed sex broiler chicks were randomly divided into 4 treatments and 3 replications, with 10 birds in each replicate in a completely randomised experimental design, with 4 silicon levels (0.00, 1.50, 2.00 and 2.50 mg of silicon oxide/litre of water. Corn-soya based diets were formulated at the starter (0–4 weeks) and finisher (5–8weeks) phases and were supplied ad libitum with free access to water. The average daily temperature and relative humidity inside the poultry house were 35.9 °C and 36%, respectively. At the starter phase, chicks administered 2.00mg silicon oxide/litre of water had significantly (p<0.05) higher final body weight (991.00g) and average weight gain (950.96g) compared to chicks without silicon oxide 778.57 g and 738.54g. The inclusion of 2.00 mg silicon oxide/litre of water improved feed conversion ratio compared to the control group (p < 0.05) and significantly reduced feed cost per kg gain. For the finisher phase, chickens administered 2.00mg silicon oxide/litre of water had the best results for final weight, weight gain and feed cost per kg gain. Also, inclusion of silicon oxide in broiler chickens water improved litter quality as predominantly dry material but with some areas of wet shavings was observed. In conclusion, silicon oxide in broiler chickens drinking water at 2.00mg/litre of water enhanced growth performance, improved feed conversion ratio and litter quality as well as reduced feed cost per kg gain at the starter and finisher phases respectively.

Water Soluble Vitamin

The water-soluble vitamin cobalamin plays a central role as a co-factor in key pathways of energy and protein metabolism. The dietary requirement of this vitamin for the young pig (5–10 kg) has been estimated at 17.5 μg kg-1, but it is derived from estimates made over 40 yr ago. In light of changes in swine production, including the selection for high lean potential genotypes and the move to earlier weaning times, a reassessment of the adequacy of current cobalamin estimates is warranted. To this end, two trials were conducted to test the following alternate hypothesis: The current National Research Council (NRC 1998) estimated cobalamin requirement for the 5- to 10-kg early-weaned piglet is inadequate to maintain optimal cobalamin status, as reflected by growth, feed conversion efficiency, plasma cobalamin and plasma homocysteine concentrations. In trial 1, 60 Cotswold pigs (17 ± 1 d, equal males and females) were randomly assigned to receive diets, formulated with ingredients essentially devoid of cobalamin, and containing either 0, 35, 70, 105, or 140 g crystalline cobalamin kg-1. After 15 d, growth, feed intake and feed conversion efficiency were not significantly different (P > 0.05) between the dietary cobalamin levels. However, plasma cobalamin was significantly lower (49.9 vs 186.7, 168.0, 164.7, and 178.7 pg mL-1; SEM 17.3; P < 0.05) and homocysteine was significantly higher (34.5 vs. 22.5, 26.0, 24.7, and 23.4 μmol L-1; SEM 2.9; P < 0.05) in piglets consuming diets containing 0 vs. 35, 70, 105 and 140 μg crystalline cobalamin kg-1, respectively. Trial 2 retained the same study design as trial 1, but added dietary cobalamin concentrations were equivalent to 0, 10, 20, 30, and 40 g kg-1. The observed pattern of responses in plasma cobalamin and homocysteine support a requirement of added cobalamin in excess of 30 μg kg-1 of diet. Taken together, the data support a requirement for the addition of 35 μg crystalline cobalamin kg-1 of a diet formulated with ingredients essentially devoid of natural cobalamin for the early-weaned piglet between 5 and 10 kg, a value that is double the current NRC requirement. In addition, the current study uses changes in the plasma concentration of the metabolite homocysteine as a novel approach for the estimation of the dietary requirement for cobalamin in animals.

Pig Performance

In 5 growth trials with a total of 420 pigs, tryptophan requirements from 20 to 40 kg liveweight were estimated. L-Tryptophan 0, 0.15, 0.30, 0.45 and 0.60 g/kg was added to a basal diet containing tapioca, barley and maize, with CP 162 g/kg and tryptophan 1.65 g/kg. The control diet was supplemented with lysine, methionine plus cystine, threonine, isoleucine, valine and histidine to assure that only tryptophan was limiting pig performance. Diets were freely given as pellets. Total tryptophan was about 2.10 g/kg for optimal weight gain and feed conversion efficiency in a diet containing NE 9.5 MJ/kg, corresponding with apparent ileally digestible tryptophan 1.77 g/kg.

Probiotic Lactic Acid Bacteria

This study aimed to determine the effect of probiotics of lactic acid bacteria in drinking water on feed consumption, weight gain and feed conversion ratio of broiler chickens. This research is an experimental research. The experimental animals used in this study were 28 male broiler chickens strain Cobb 700 aged 20 days. P0 was not given the addition of probiotic lactic acid bacteria, P1 was given the addition of probiotic lactic acid bacteria Lactobacillus acidophilus in 1ml/liter drinking water, P2 was given the addition of probiotic lactic acid bacteria Lactobacillus casei in drinking water 1ml/liter, P3 was given the addition of probiotic lactic acid bacteria Lactobacillus fermentum in drinking water 1ml/liter, P4 was given the addition of probiotic lactic acid bacteria Lactobacillus plantarum in drinking water 1ml/liter, P5 was given the addition of probiotic lactic acid bacteria Pediococcus in drinking water 1ml/liter, P6 was given the addition of probiotic mix lactic acid bacteria in drinking water 1ml /liter. Collecting data for the last 1 week by weighing the remaining consumption of feed given and weight gain of broiler chickens. The data obtained were analyzed using the Analysis of Variant (ANOVA) statistical method and continued with Duncan. Based on the results of the calculation of the amount of feed consumption and weight gain in broiler chickens, it showed that the administration of probiotic lactic acid bacteria 1ml/liter of water in broiler chickens could increase body weight gain, reduce feed conversion rates but did not reduce broiler feed consumption (p<0.05).

Dried plantain (Musa paradisiaca) peels (DPP), either ripe or unripe (green), were given to Weaned rabbits to replace maize at O, 10, 20 and 30% levels in isonitrogenous (18% crude protein) diets for 56 days in a 2 x 4 factorial experiment. The 30% inclusion level of DPP depressed (P < 0.05) the final weight gain, daily weight gains, and feed conversion efficiency. Ripe or unripe DPP had no significant (P < 0.05) effect on the performance parameters except feed intake, which was improved (P < 0.05). The interaction between ripe or unripe DPP and inclusion levels significantly (P < 0.05) affected weight gain and feed conversion efficiency. Inclusion of DPP depressed (P < 0.05) dressing percentage and lumbar and limbs weights while the viscera weight was increased Ripeness the plantain peels had no significant effect (P < 0.05) on the carcass yield. There was also increase in profit margin expressed in terms of feed cost/ kg live weight gain with inclusion of plantain peel in the diet. The results of this study showed that ripeness slightly improved the nutritive value of DPP which can be included al 20% in weaned rabbits ' diet to replace maize.

Green Seaweed

Using seaweeds as sources of nutrients and beneficial bioactive compounds can promote sustainable production of functional poultry products. This study investigated the physiological and meat quality responses of Cobb 500 broiler chickens to graded levels of green seaweed (Ulva sp.) meal (SWM). Three hundred, two-week-old male chicks (159.3 ± 11.76 g live-weight) were randomly assigned to five diets formulated by diluting a standard broiler diet with SWM at 0 (SW0), 20 (SW20), 25 (SW25), 30 (SW30) and 35 g/kg (SW35). There were neither linear nor quadratic trends (p > 0.05) for overall feed intake, overall growth performance and carcass and meat quality traits. Overall feed conversion efficiency (R2 = 0.192, p = 0.018) and spleen weights (R2 = 0.182; p = 0.020) linearly declined as SWM levels increased. Linear and quadratic responses (p > 0.05) were observed for lymphocytes. There were linear effects for meat pH except on day 7 of storage. Meat lightness (L*) linearly increased whereas meat redness (a*) quadratically responded to SWM levels (day 3 of storage). While an optimum inclusion level could not be established for seaweed based on growth performance, improvements in some meat shelf life indicators were observed in the broilers reared on seaweed-containing diets.
