Effect of soluble probiotic on production performance of Akar Putra chicken

The present study was conducted to investigate the effect of soluble probiotic on the production parameters of local Malaysian chicken (Akar Putra). A total of seventy two 1-day-old Akar Putra chicks were randomly assigned to three treatment groups, each having 3 replicates of 8 chicks. The treatments were as follows: (T1) control, (T2) probiotic supplemented at 1 g/liter tap water, (T3) probiotic supplemented at 2 g/liter tap water. The results revealed that supplementation of soluble probiotic at both the rates resulted in an improved performance of male and female Akar putra chicken. Birds who received 2 g of prepared probiotic per liter of water (T3) exhibited highly improved (p<0.05) body weight, weight gain and feed conversion ratio than other groups. It can be concluded that supplementation of prepared soluble probiotic would be economically beneficial in improving the production performance and health status of Akar Putra chicken

Impact of daily supplement of probiotic on the production performance of Akar Putra chickens

This study was conducted to investigate the effects of prepared probiotic (PP) on the live body weight, weight gain, feed intake and feed conversion ratio in Malaysian chicken (Akar Putra). A total of 72 day-old Akar Putra chicks were reared for 12 weeks and randomly assigned to three dietary treatments (24 chicken/treatment), with 3 replications for each (8 chicken/replicate). The treatments consisted of a control group (T1), and the supplemented diet with probiotic in the second treatment was prepared at the rate 1:1 (1 kg of commercial broiler feed + 1 g PP). While the rate was 1:2 (1 kg of commercial broiler feed + 2 g PP) in the third treatment. Supplementing probiotic in both rates revealed significant improvement in terms of males' and females' growth rates, final live body weight, weight gain and feed conversion ratio. Based on the research findings, the best results were obtained when chickens received 1 g PP in males and 2 g in females

Partial ablation of uropygial gland effects on growth hormone concentration and digestive system histometrical aspect of Akar Putra chicken

Partial ablation of the uropygial gland is being used in the poultry industry as a new way to enhance body performance of chickens. However, limited data are available estimating the efficacy of partial uropygialectomy (PU) to improve body organ activity. The present study evaluated the effect of partial ablation of the uropygial gland on the serum growth hormone concentration level and digestive system histology of 120 Akar Putra chickens in 5 trials with 3 replicates per trial. The experimental treatments consisted of a control treatment T1; partial ablation of the uropygial gland was applied in the T2, T3, T4, and T5 treatments at 3, 4, 5, and 6 wk of age, respectively. Feed and water were provided ad libitum. All treatment groups were provided the same diet. Venous blood samples were collected on wk 7, 10, and 12 to assay the levels of growth hormone concentration. On the last d of the experiment, 4 birds per replicate were randomly isolated and euthanized to perform the necropsy. Digestive system organs' cross sections were measured by a computerized image analyzer after being stained with haematoxylin and eosin. In comparison with the control group, surgical removal of the uropygial gland, especially at wk 3, had a greater (P < 0.01) effect on the total duodenum, jejunum, and ilium wall thickness. In addition, effects (P < 0.05) were observed on the wall thickness of males’ cecum and colon. Moreover, the wall layers of the esophagus, proventriculus, gizzard, and rectum were not affected by the treatment. However, removing the uropygial gland showed significant impact (P < 0.05) in males’ growth hormone concentration level at wk 7 and (P < 0.01) effects at wk 12 in both sexes. This study provides a novel and economic alternative to enhance the body performance of poultry in general and Akar Putra chickens particularly

Effect of dry probiotic supplemented fermented feed on production performance of Akar Putra chicken

During the recent years, solid state fermented feed (SSFF) has been introduced with great success in poultry nutrition. Thus, the present experiment was conducted to evaluate the effect of dry fermented feed with prepared probiotic (PP) on the live body weight, weight gain, feed intake and feed conversion ratio of a local Malaysian chicken (Akar Putra). The experiment comprised of 3 treatments (24 chicken/treatment), with 3 replicates of each (8 chicken/replicate). The treatments consisted of a control group (T1), the mixture of SSFF and PP at the rate 1:1:1 (1 kg of commercial broiler feed+1 liter tap water+1 g PP) in T2 and 1:1:2 (1 kg of commercial broiler feed+1 liter tap water+2 g PP) in T3. The results revealed remarkably significant (p<0.01) improvement in both male and female chicken in terms of final body weight gain, feed intake and feed conversion ratio in treatment groups (T2 and T3) when compared to the control group. The variation ratio of production performance parameters was calculated and best results were indicated in T2 group wherein, 1 g prepared probiotic was used

Partial ablation of uropygial gland effect on carcass characteristics of Akar Putra chicken

This study evaluated the effect of partial uropygialectomy (PU) on carcass traits of male and female Akar Putra chickens. Sixty chicks of each sex were evenly distributed into 5 treatment groups with 3 replicates per group containing 4 males and 4 females each, and reared for 12 wk. Homogeneity of the groups was satisfied with regard to the parity. Experimental treatments consisted of a control treatment (T1), and partial ablation of the uropygial gland was applied on the second, third, fourth, and fifth treatments at 3, 4, 5, and 6 wk of age, respectively. The chickens were fed ad libitum the same diets (1 to 13 d: starter; 14 d to slaughter: finisher). On the last d of the experiment, 12 birds were randomly selected from each treatment group (2 males and 2 females per replicate) and slaughtered to determine carcass characteristics, which included carcass weight, dressing percentage with or without eating giblets, and the relative weights of heart, liver, gizzard, thighs, wings, breast, back, and neck. From the results of the study, it was shown that the partial ablation of the uropygial gland at all ages had certain dependent effects concerning some carcass parameters, as shown by higher breast and back relative weights in males and breast relative weight in females. As a consequence, a positive effect also was noticed regarding the carcass morphology in terms of the increase in dressing percentage with or without eating giblets thus leading to an increase in the body weight and carcass weight. Furthermore, the best result was obtained in the second treatment when PU was applied at 3 wk of age compared with other experimental groups. Moreover, the current study provides a novel and economic alternative to enhance the body performance of poultry in general and Akar Putra chicken particularly

The phylogeography of Indoplanorbis exustus (Gastropoda: Planorbidae) in Asia

<p>Abstract</p> <p>Background</p> <p>The freshwater snail <it>Indoplanorbis exustus </it>is found across India, Southeast Asia, central Asia (Afghanistan), Arabia and Africa. <it>Indoplanorbis </it>is of economic importance in that it is responsible for the transmission of several species of the genus <it>Schistosoma </it>which infect cattle and cause reduced livestock productivity. The snail is also of medical importance as a source of cercarial dermatitis among rural workers, particularly in India. In spite of its long history and wide geographical range, it is thought that <it>Indoplanorbis </it>includes only a single species. The aims of the present study were to date the radiation of <it>Indoplanorbis </it>across Asia so that the factors involved in its dispersal in the region could be tested, to reveal potential historical biogeographical events shaping the phylogeny of the snail, and to look for signs that <it>I. exustus </it>might be polyphyletic.</p> <p>Results</p> <p>The results indicated a radiation beginning in the late Miocene with a divergence of an ancestral bulinine lineage into Assam and peninsular India clades. A Southeast Asian clade diverged from the peninsular India clade late-Pliocene; this clade then radiated at a much more rapid pace to colonize all of the sampled range of <it>Indoplanorbis </it>in the mid-Pleistocene.</p> <p>Conclusions</p> <p>The phylogenetic depth of divergences between the Indian clades and Southeast Asian clades, together with habitat and parasitological differences suggest that <it>I. exustus </it>may comprise more than one species. The timescale estimated for the radiation suggests that the dispersal to Arabia and to Southeast Asia was facilitated by palaeogeographical events and climate change, and did not require human involvement. Further samples from Afghanistan, Africa and western India are required to refine the phylogeographical hypothesis and to include the African Recent dispersal.</p

Effects of moist and fermented feed with probiotic displacement levels in broiler nutrition on morphology and histology of the intestine

Objective: The aim of this study was to investigate the intestinal morphology and histology effectiveness of broiler chicks fed on moist and different levels of fermented feed with probiotic. Methodology: Three hundred sixty 1-d-old Ross308 broiler chicks were allocated in six experimental treatments for six wk. Chicks in the six treatment groups were fed as follows: (T1) Control group fed on dry feed, (T2) Fed on wet feed (1:1, feed: water). (T3) 25% fermented feed + 75% dry feed, (T4) 50% fermented feed + 50% dry feed, (T5) 75% fermented feed + 25% dry feed, (T6) 100% fermented feed throughout the experimental period. Each treatment had 3 replicates of 20 broilers each. The chicks were raised in a temperature and humidity controlled room with a 24-h. Constant light schedule and ad. Libitum access of water and feed throughout the experimental period were provided. Results: Treatment effects on relative weight and length of the fine intestine including duodenum, jejunum, ileum, and ceca. As well as, the values of villi height, crypt depth, percentage of villi height to crypt depth in duodenum, jejunum and ileum. Differences among treatments were considered significant when P ≤ 0.05. Conclusion: It is concluded that fermented feed with probiotic had a significant effect on morphology and histology of broiler intestine specially: villus height and the villus height to the crypt depth ratio of all duodenum, jejunum, and ileum

Understanding Giardia infections among rural communities using the one health approach

The epidemiology of giardiasis in rural villages in Peninsular Malaysia was examined in the context of the One Health triad that encompasses humans, animals and environment (i.e. river water). A cross-sectional study was carried out among five rural communities in Malaysia to determine the prevalence of Giardia duodenalis in humans, animals and river water. Fecal samples collected from humans and animals were examined by light microscopy. Water was sampled from the rivers adjacent to the target communities and investigated for the occurrence of Giardia cysts. The isolated cysts were further genotyped targeting the glutamate dehydrogenase and triosephosphate isomerase genes. The overall prevalence of G. duodenalis was 6.7% (18/269) and 4.7% (8/ 169) among humans and animals, respectively. Giardia cysts (mean concentration range: 0.10–5.97 cysts/L) were also found in adjacent rivers at four out of the five villages examined. At Kemensah and Kuala Pangsun, Giardia cysts were isolated from humans [rate: 3.7% each (of 54 each)], animals [rates: 6.3% (of 62) and 11.3% (of 16), respectively] and river water [average concentration of 9 samples each: 0.83 ± 0.81 and 5.97 ± 7.00, respectively]. For both villages at Pos Piah and Paya Lebar, 12.2% (of 98) and 6.1% (of 33) of collected human samples were infected, respectively whilst none of the collected animals samples in these villages were found to be positive. The river water samples of these two villages were also contaminated (average concentration: 0.20 ± 0.35 (of 9) and 0.10 ± 0.19 (of 3), respectively). In conclusion, Giardia cysts were simultaneously observed in the human-animal-environment (i.e., river water) interfaces in at least two of five studied communities highlighting a vital need to improve understanding on the interplay of transmission dynamics, the role of infected humans and animals in contaminating the water sources and the role of water as a vehicle of disease transmission in these communities. Indeed, this study illustrates the One Health approach which is to recognize that the optimal health of humans are interconnected with the well-being of animals and their environment

Global economic burden of unmet surgical need for appendicitis

Background: There is a substantial gap in provision of adequate surgical care in many low-and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods: Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results: Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion: For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially
