Critical Moments

Phytobiotics are usually tested in feed and throughout the production cycle. However, it could be beneficial to evaluate their effects when administered only during critical moments, such as changes in feeding phases. The aim of the trial was to investigate the effect of a commercial plant extract (PE; IQV-10-P01, InQpharm Animal Health, Kuala Lumpur, Malaysia) on growth performance, blood antiradical activity and cecal microbiome when administered in drinking water to broiler chickens during the post-hatching phase and at each change of diet. In the experiment, 480 1-day-old male broiler chicks were assigned to two groups in a 50-day trial. Broilers received drinking water (C) or drinking water plus PE (T) at a rate of 2 mL/L on days 0 to 4, 10–11 and 20–21. PE did not affect performance and water intake, while total antiradical activity was improved (p < 0.05). A greater abundance of lactic acid bacteria (false discovery rate (FDR) < 0.05) was found in the T group and the result was confirmed at a lower taxonomic level with higher Lactobacillaceae abundance (FDR < 0.05). Our findings suggest that PE administration during critical moments of the production cycle of broiler chickens may exert beneficial effects at a systemic level and on gut microbial ecology.

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.

Spray Dried

The influence of feeding with starter diets containing spray-dried bovine colostrum (SBC), spray-dried bovine plasma (SBP), or spray-dried porcine plasma (SPP) on the growth performance and gut morphology of broiler chickens was investigated. The crude protein, lysine, and methionine plus cystine contents (g/kg as received) of SBC, SBP, and SPP were determined to be 766, 736, and 684; 58, 61, and 55; and 27, 28, and 24, respectively. The 3 test proteins were incorporated into a maize–soybean meal diet at a level of 50 g/kg and fed to 6 replicates of 8 male broiler chicks from 1 to 14 days of age. On Day 14, the experimental diets were replaced with a common grower-finisher diet, which was offered until Day 35. Dietary treatments had no effect (P > 0.05) on the weight gain or feed intake of birds during the first 14 days. However, feed/gain of birds fed the SBC diet was lower (P < 0.05) than of those fed the control diet. A trend for a reduction in feed/gain (P = 0.06) was observed in SBP and SPP diets. Dietary treatments had no effect (P > 0.05) on performance during Days 14–35 or Days 1–35. Villus height was increased by 5.7% (P < 0.05) and 4.6% (P = 0.05) in birds fed the SPP and SBP diets, respectively, compared with those fed the control diet. Crypt depth was 6% greater (P < 0.05) in birds fed the SPP diet and tended (P = 0.08) to be greater in birds fed the SBC diet, compared with birds fed the control. The ratio of villus height to crypt depth tended (P = 0.06) to be lower in birds offered the SBC diet compared with the control. Crypt goblet cell density was reduced (P < 0.05) by 13.9% in birds fed the SBC diet, compared with control birds. These results suggest that feeding with diets containing the SBC, SBP, and SPP during 1–14 days of age has some beneficial effects on broiler chickens. Further studies are needed to evaluate these products in less sanitary environments, which may increase the positive responses.

Background and Aim: Wood vinegar is a product generated from the combustion and distillation of wood and other plant materials. It has been shown to suppress bacteria, resulting in healthier livestock and increased yields. This study aimed to determine the efficacy of drinking water supplemented with wood vinegar on growth performance, intestinal health, and gut microbial of broilers. Materials and Methods: A total of 120 Ross 308 1-day-old male broiler chicks were randomly distributed in a completely randomized experimental design. The study consisted of three treatments containing four replicates, with 10 birds in each. Treatments were given 0.5% and 1.0% (V/V) wood vinegar supplemented in drinking water, while no supplementation was given to the control group. The animals were raised in an open-house system. All groups were provided with a commercial diet and drinking water ad libitum. Analysis of variance was conducted using the general linear model procedure to compare the levels of wood vinegar supplementation in drinking water on growth performance, intestinal morphology, and gut microbial. Results: No significant differences (p>0.05) were found for body weight gain, feed intake, feed conversion ratio, and water consumption between groups during the starter (1-21 days old), grower (22-35 days old), and whole (1-35 days old) growth periods. Moreover, no significant differences in villi height and crypt depth (p>0.05) at 21 and 35 days of age were found. In addition, no significant difference in terms of lactic acid bacteria and Escherichia coli was found between the different treatments. Conclusion: Drinking water supplemented with wood vinegar was not found to have an effect on the growth performance and gut microbial of broiler chickens in the present study. However, the supplementation of wood vinegar in drinking water could improve intestinal morphology.

Two thousand four hundred male broiler chicks were used in three experiments to evaluate the biological and economic effects of using arsanilic acid as a growth promoter. In two experiments four treatments were (A) control diets (CD); (B) CD plus 99 mg kg−1 arsanilic acid; (C) CD plus drinking water containing arsanilic acid calculated to achieve equivalent exposure to treatment B; and (D) same as treatment C except arsanilic acid concentration reduced by 50%. A third experiment evaluated the dietary addition of arsanilic acid at 0, 33, 66 and 99 mg kg−1. Arsanilic acid supplementation had no significant (P > 0.05) effect on mortality, feed conversion, final live body weights or monetary returns at slaughter age (42 d). Analysis of breast, thigh and liver tissues using method with a sensitivity of 0.02 mg kg−1 showed a significant increase in liver arsenic residues when supplemented diets were fed to slaughter age. Withdrawal of arsanilic acid from diets 7 d prior to slaughter returned the arsenic residues to normal background (control) levels. It is concluded that the use of arsanilic acid at dietary concentrations up to 99 mg kg−1 (the maximum permissible in Canada) was ineffective in improving either the biological or economic performance of broiler chickens. Key words: Arsanilic acid, growth promoter, broiler chickens

The study was carried out to know the effects of probiotics (Proetxin® Boost, Novartis Bangladesh Ltd.) and antibiotic (oxytetracycline-Renamycin®, Renata Animal Health) on growth performances and haemato-biochemical parameters of "Shaver Star Bro" broiler chickens during September and October 2003. A total of 20, day old broilers were randomly selected and assigned into four equal groups n = 5) as A, B, C and D. Group A was considered as control group fed with commercial ration while groups B, C and D were fed with commercial ration with the addition of 200 mg probiotics / liter drinking water, 100 mg probiotics and 50 mg antibiotic (oxytetracycline- Renamycin®) / liter drinking water and 100 mg antibiotic (oxytetracycline- Renamycin®) / liter drinking water respectively up to 35 days of age. The results showed that the body weight gains differed significantly (p < 0.05) at the 2nd, 4th and 5th weeks of age in different treatment groups. The meat yield not differed significantly (p > 0.05). The drumstick, wing differed significantly (p < 0.01) and spleen weight differed at p < 0.05 among different groups. The mean haemato-biochemical values of Hb, ESR, PCV, heterophil, eosinophil, basophil, triglyceride, HDL, LDL, SGPT and SGOT were differed significantly (p < 0.01) in different groups. The present findings suggest that supplementation of probiotics has significant effect on growth performance and certain haemato-biochemical parameters of broiler chickens as compared to antibiotic supplementation.

An experiment was carried out to investigate the effects of using garlic (Allium sativum) as an additive on haematological profile in broiler chicken production. The study was carried out at Livestock Investigation Department (L.I.D) of the National Veterinary Research Institute (N.V.R.I), Vom. The experiment lasted eight weeks. A total of 144, one day-old broiler chicks of Arbor acre breed were used for the study in a completely randomized design (CRD). The birds were allotted into four (4) dietary treatments with each having three (3) replicates. Processed and ground garlic was added into the drinking water of each treatment at 0g, 3g, 6g and 9g per liter of drinking water representing treatments 1, 2, 3 and 4, respectively. The result of haematological analysis showed that all the parameters were significantly (P<0.05) different across the dietary treatments. The white blood cells in T4 (12.13) which is higher than 10.21, 8.65 and 7,68 respectively. This indicates that the health of the birds was challenged in T4 even though they are all within the normal range (Merck's Manual, 1998). Packed cell volume (PCV) level of T4 was the Lowest among the dietary treatments. It can therefore be concluded that garlic used as an additive in drinking water showed no deleterious effect in haematological parameters of broiler chickens rather it boosted their immunity.

This study was conducted in order to investigate the effects of a multivitamin complex and probiotic blend in drinking water before and after vaccination on growth performance, carcass traits, blood biochemical parameters and humoral immune response of broiler chickens. A total of 150 one day-old male broiler chicks (Ross 308) were randomly allocated to five treatment groups, with three replicates (10 birds per replicate) in a completely randomized design. Experimental treatments consisted of: 1) a basal diet and drinking water without any additives as control (C); 2) C + drinking water + multivitamin complex from 2 days before vaccination until 3 days after vaccination; 3) C + drinking water + multivitamin complex for 3 days after vaccination; 4) C + drinking water + probiotic blend from 2 days before vaccination until 3 days after vaccination; and 5) C + drinking water + probiotic blend for 3 days after vaccination. In the whole experimental period, feed intake, body and thigh weight and abdominal fat were significantly affected (P<0.05) by dietary treatments. On the contrary, no significant effect was observed on carcass characteristics, feed conversion ratio, blood parameters, antibody production against SRBC and IgG. The titer of IgM was higher in treatment (2) than other treatments at 28 d of age (P<0.05). In conclusion, a multivitamin complex supplied in drinking water for 2 days before vaccination till 3 days after vaccination is enable to improve broiler performance and immunity.

ABSTRACTProbiotics have been demonstrated to promote growth, stimulate immune responses, and improve food safety of poultry. While widely used, their effectiveness is mixed, and the mechanisms through which they contribute to poultry production are not well understood. Microbial phytases are increasingly supplemented in feed to improve digestibility and reduce antinutritive effects of phytate. The microbial origin of these exogenous enzymes suggests a potentially important mechanism of probiotic functionality. We investigated phytate degradation as a novel probiotic mechanism using recombinantLactobacilluscultures expressingBacillus subtilisphytase.B. subtilis phyAwas codon optimized for expression inLactobacillusand cloned into the expression vector pTRK882. The resulting plasmid, pTD003, was transformed intoLactobacillus acidophilus,Lactobacillus gallinarum, andLactobacillus gasseri. SDS-PAGE revealed a protein in the culture supernatants ofLactobacilluspTD003 transformants with a molecular weight similar to that of theB. subtilisphytase. Expression ofB. subtilisphytase increased phytate degradation ofL. acidophilus,L. gasseri, andL. gallinarumapproximately 4-, 10-, and 18-fold over the background activity of empty-vector transformants, respectively. Phytase-expressingL. gallinarumandL. gasseriwere administered to broiler chicks fed a phosphorus-deficient diet. Phytase-expressingL. gasseriimproved weight gain of broiler chickens to a level comparable to that for chickens fed a control diet adequate in phosphorus, demonstrating proof of principle that administration of phytate-degrading probiotic cultures can improve performance of livestock animals. This will inform future studies investigating whether probiotic cultures are able to provide both the performance benefits of feed enzymes and the animal health and food safety benefits traditionally associated with probiotics.

The challenge of antibiotics resistance and the fatality of its residues in human and animal health led to the ban of antibiotic growth promoters in animal diets. This has prompted the search for alternatives; especially through phytobiotic investigations. Therefore, this study investigated the effects of aqueous dried calyx extract of roselle plant on the haematological and serum biochemical responses of broiler chickens with the aim of establishing its optimal level as nutrient additive. The five varying concentration levels- 0, 5, 10, 20 and 30 ml of 2 litres of calyx extract solution per litre of drinking water were treatments T1, T2, T3, T4 and T5 respectively. Thirty broiler chickens were randomly assigned per treatment of three replicates each. The experiment lasted for eight weeks. The results revealed significant differences in the haematological parameters. However, the values of white 3 3 blood cells (WBC) (11400.00×10 /µl - 13466.67×10 /µl), lymphocyte (ranged between 48.33 and 61.33%), monocytes (2.00-3.67%), eosinophils (1.67-5.00%) and basophil (0.00 – 1.00%) were within the normal range for healthy chickens. Hence, roselle plant aqueous extract maintained the haematological content of the blood. The level of lymphocyte revealed adequate production of antibodies that prevented the occurrence of bacterial infection or allergic condition throughout experimental period. The influence of aqueous roselle plant on the levels of aspartate transaminase (AST) and albumin (ALB) indicated uncompromised liver function. Therefore, haematological and serum biochemistry parameters showed enhanced health and the wellbeing of the broiler chickens. The 5 ml and 10 ml levels of the extract of dried roselle calyx in drinking water were found to be similarly optimal in terms of lymphocyte levels. Levels above 10 ml could be detrimental to the health andwellbeing of the chickens. Key words: Blood constituents, Chicken health, Drinking water, Roselle calyx extract
