Abstract. Zalizar L, Winaya A, Malik A, Widodo W, Suyatno, Anggraini AD. 2021. Species identification and prevalence of gastrointestinal helminths in Indonesian native chickens, and its impact on egg production. Biodiversitas 22: 4363-4369. Gastrointestinal parasite (GIP) infection is a severe problem of local chicken production, such as poultry and egg. Hence, the proper strategy to control the parasite invasion should be implemented regarding chicken productivity performance. Moreover, the existing environment is also essential in supporting chicken production. The study's objective was to determine the prevalence rate of the gastrointestinal helminths in four strains of Indonesian native chicken viz. Ranupane, Lokal Putih, Wareng, and Lurik, and the impact of the chicken egg production. A total of 280 chickens which were evaluated consisting of 70 birds from each strain, were tested for the prevalence of helminths eggs in a sample of feces and the effect on hen day production (HDP). The results showed that the percentage rates of infected chicken with helminths reached 56.43%, and the number of eggs per gram (EPG) in all four strains was considered moderate (115 EPG of feces). At the same time, the average of HDP per the four strains at 7 to 12 months was about 34.36-45.80%, which was in a normal range. The majority of helminths species found in examined native chicken were Ascaridia galli, Heterakis gallinarum, Raillietina spp., and Capillaria spp. The prevalence of GIP helminths did not negatively affect egg production in all four strains of chicken by moderately tolerant infections, and the HDP of chickens was normal.

UTILIZATION OF MANURE DEGRADED BY BLACKFLIES LARVAE (HERMETIA ILLUCENS L) ON THE PERFORMANCE OF LAYING NATIVE CHICKEN. Native chicken is one of the livestocks that have been widely used for source of protein. It has already been maintained everywhere in Indonesia. Native chickens is widely kept for eggs because it contains good nutrients for human beings. One of the source of rations for native chicken is manure flour from the degradation of the blackflies larvae (MHD flour). This feed material contains a good nutritional value for this chicken. In this study the results of the degradation of manure blackflies larvae processed into flour and added into the rations with the aim to know the consumption of rations, egg production and rations conversion of native chicken. 40 native chickens females aged 56 weeks had been used.Baterry system cages of 50x50x75 cm in size was used to kept the native chickes. Placement of chicken in each unit was done randomly. A randomized complete design (RAL) with 4 treatment and 5 replications was used as design methods (Steel and Torrie, 1991). Each replication using native chickens age 56 weeks with the following treatments: R0 = 0% flour MHD: R1 = 5% flour MHD: R2 = 10% flour MHD: R3 = 15% flour MHD. The variable measured is the sum of rations consumption, egg production and rations conversion. The results obtained showed that there was highly significant difference (P < 0.01)between treatmentsandrations consumption, egg production, and there was no significant difference (P > 0.05) between treatmens and rations conversion. It can be concluded that as much as 15% of the MHDcan be used in chicken rations. Keywords: Native Chicken, Black Flies, MHD flour.

Virulent and multi drug resistant (MDR) Salmonellaenterica is a foremost cause of foodborne diseases and had serious public health concern globally. The present study was undertaken to identify the pathogenicity and antimicrobial resistance (AMR) profiles of Salmonellaenterica serovars recovered from chicken at wet markets in Dhaka, Bangladesh. A total of 870 cecal contents of broiler, sonali, and native chickens were collected from 29 wet markets. The overall prevalence of S. Typhimurium, S. Enteritidis, and untyped Salmonella spp., were found to be 3.67%, 0.57%, and 1.95% respectively. All isolates were screened by polymerase chain reaction (PCR) for eight virulence genes, namely invA, agfA, IpfA, hilA, sivH, sefA, sopE, and spvC. S. Enteritidis isolates carried all virulence genes whilst S. Typhimurium isolates carried six virulence genes except sefA and spvC. A diverse phenotypic and genotypic AMR pattern was found. Harmonic descending trends of resistance patterns were observed among the broiler, sonali, and native chickens. Interestingly, virulent and MDR Salmonella enterica serovars were found in native chicken, although antimicrobials were not used in their production cycle. The research findings anticipate that virulent and MDR Salmonella enterica are roaming in the wet markets which can easily anchor to the vendor, consumers, and in the food chain.

The Impact

Lipid metabolism in avian species places unique demands on the liver in comparison to most mammals. The avian liver synthesizes the vast majority of fatty acids that provide energy and support cell membrane synthesis throughout the bird. Egg production intensifies demands to the liver as hepatic lipids are needed to create the yolk. The enzymatic reactions that underlie de novo lipogenesis are energetically demanding and require a precise balance of vitamins and cofactors to proceed efficiently. External stressors such as overnutrition or nutrient deficiency can disrupt this balance and compromise the liver’s ability to support metabolic needs. Heat stress is an increasingly prevalent environmental factor that impairs lipid metabolism in the avian liver. The effects of heat stress-induced oxidative stress on hepatic lipid metabolism are of particular concern in modern commercial chickens due to the threat to global poultry production. Chickens are highly vulnerable to heat stress because of their limited capacity to dissipate heat, high metabolic activity, high internal body temperature, and narrow zone of thermal tolerance. Modern lines of both broiler (meat-type) and layer (egg-type) chickens are especially sensitive to heat stress because of the high rates of mitochondrial metabolism. While this oxidative metabolism supports growth and egg production, it also yields oxidative stress that can damage mitochondria, cellular membranes and proteins, making the birds more vulnerable to other stressors in the environment. Studies to date indicate that oxidative and heat stress interact to disrupt hepatic lipid metabolism and compromise performance and well-being in both broilers and layers. The purpose of this review is to summarize the impact of heat stress-induced oxidative stress on lipid metabolism in the avian liver. Recent advances that shed light on molecular mechanisms and potential nutritional/managerial strategies to counteract the negative effects of heat stress-induced oxidative stress to the avian liver are also integrated.

The Impact

The establishment of efficient and sustainable production of industrially important insects necessitates the detailed knowledge of the optimal mixture of macronutrients required for maximising their performance and fitness. The white spotted flower chafer, Protaetia brevitarsis (Coleoptera: Scarabaeidae: Cetoniinae), is one of the most important edible insects in East Asia with high nutritional and medicinal value. Here, we report how the ratio of protein to digestible carbohydrate (P:C) in the diet influenced lifespan and reproductive performance in the adults of P. brevitarsis. Throughout their lifespan, beetles were fed ad libitum one of five diets with differing P:C ratio (0:1, 3:7, 1:1, 7:3, 1:0). Both lifespan and the number of eggs produced over the lifetime were maximised at the P:C ratio of 3:7 and declined as the ratio deviated away from this optimal P:C composition. Beetles fed a diet containing only protein (P:C 1:0) not only had the shortest lifespan but also exhibited substantially reduced lifetime egg production compared to those fed the other diets. However, the effects of dietary P:C ratio on daily egg production rate and egg hatchability were marginal. The number of eggs produced at each age stage peaked at the age of week 2 and then gradually declined with increasing age, showing the sign of reproductive senescence. Age-specific egg production was higher in beetles confined to three intermediate P:C ratios (3:7, 1:1, 7:3) than those confined to two extreme P:C ratios (0:1, 1:0) throughout their lifespan. The speed of age-related decrease in reproductive performance was the slowest at P:C 3:7. Our data have implications for optimising the production of this edible insect with emerging economic importance.

Background: Prolactin is a physiological candidate gene which has significant effects on egg production in poultry. Also, it plays a major role on incubation behaviour (broodiness) in birds. The main objective of the present study was identification of single nucleotide polymorphism (SNP) C-2161G in the promoter region of prolactin gene and its association with egg production in Tellicherry native chicken population. Methods: A total of 200 blood samples were collected from the randomly selected birds of Tellicherry native chicken in All India Co-ordinated Research Project on Poultry improvement (AICRP) farm, Mannuthy, Thrissur, Kerala. Isolation of Genomic DNA was done and the isolated samples were subjected to polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) analysis to identify the SNP C-2161G of prolactin gene. Result: On the basis of RFLP patterns, birds were designated with three different genotypes namely CC, CG and GG. The allelic and genotypic frequency was calculated. The observed genotypic frequency at the SNP site C-2161G was CC (0.61), CG (0.160) and GG (0.23) and the frequency of allele was 0.69 for C and 0.31 for G. The egg production was shown to be statistically similar for the genotypes of SNP C-2161G.

Background: Producing Thai native chickens through feed commercial is costly. To reduce the cost, native chicken could be fed with local plants or agricultural waste. Hyrrilla verticillate, a dominate macrophyte in Songkhla Lagoon, contain high crude protein and nitrogen free extract. Therefore, this research studied the use of Hydrilla verticillate in Thai native chicken diet on production performance, carcass characteristics and production cost. Methods: The experiment was executed in a completely randomized design (CRD) with 180 one-day-old commercial Thai native chicks. Four dietary treatments supplemented with 0%, 5%, 10% and 15% Hydrilla verticillata were formulated for three different phases of the experimental chickens: starter (1-4 weeks), grower (5-8 weeks) and finisher (9-12 weeks). Two chickens from each replicate were chosen for the carcass characteristics study. Result: During the starter phase, there was no notable effect shown among the chickens fed with the diet containing Hydrilla verticillata in terms of feed intake (FI) and body weight gain (BWG) (P greater than 0.05). The control chickens had best feed conversion ratio (FCR) (P less than 0.05), while the grower and the finisher periods, provided with different levels of Hydrilla verticillata, revealed no apparent differences (P greater than 0.05) concerning FI, BWG and FCR. Considering carcass characteristics, there were significant differences in live weight (LW) (P less than 0.05). But, no significant differences between treatments for hot carcass percentage, pectoralis majors, pectoralis minorstrip, thighs, wings, drumsticks and total edible carcass (P greater than 0.05). There were also statistical divergences regarding gizzard weight (GW) (P less than 0.05).

The efficacy of diatomaceous earth (DE) on growth rate, egg production and on increasing feed conversion efficiency in deep litter raised layer hens was evaluated. The study was conducted at Mukono Zonal Agricultural Research and Development Institute (MUZARDI) in Uganda. Worms were collected from fresh intestines of indigenous chicken obtained from Kalerwe chicken market near Kampala. The DE was mined in Pakwach (formerly Nebbi) district in Northern Uganda. Chickens of the Lohmann Brown breed raised on deep litter were studied. At 7 weeks the birds were divided into 5 treatment groups, A, B, C, D and E each composed of 40 birds. Groups C, D and E were given an oral dose containing 250 embryonated eggs of A. galli while groups A and B were not infected. The chicks were weighed; and subjected to feeding trials as arranged below: A – Non-infected birds on DE (4%) supplemented diet; B –non-infected birds on neither piperazine (a conventional de-wormer) nor DE; C – infected birds on DE supplemented diet; D – infected birds on piperazine; and group E – infected birds on neither DE nor piperazine applied. Fecal samples were collected and analysed in the laboratory biweekly at week 16 till week 22 respectively for fecal egg counts. In a subsequent experiment, day-old layer chicks from Lohmann Brown strain but different from those used in earlier experiments, were used to assess the effect of DE on egg production. At 17 weeks of age the 420 were divided as follows: 6 treatment groups each having 7 replicates and each replicate having 10 birds. This study showed that DE can be used successfully in growing pullet diets to correct nutritional mineral imbalance since it supplies more than 14 trace elements and other elements. Diatomaceous earth also enables pullets to cope with Ascaridia galli load; and 2% DE supplementation did not have significant improvement on egg production as compared to no supplementation at all. However, reduction in egg production was experienced when supplementation with levels of DE higher that 2% was applied. Results from biweekly fecal analyses showed significant differences in fecal egg counts (p<0.05); and treatment by group (p<0.05).

AbstractEpidemiological and microbiological data on Vibrio cholerae isolated between 2004 and 2017 (n=836) and held in the Public Health England culture archive were reviewed. The traditional biochemical species identification and serological typing results were compared with the genome derived species identification and serotype for a sub-set of isolates (n=152). Of the 836 isolates, 750 (89.7%) were from faecal specimens, 206 (24.6%) belonged to serogroup O1 and seven (0.8%) were serogroup O139, and 792 (94.7%) isolates from patients reporting recent travel abroad, most commonly to India (n=209) and Pakistan (n=104). Of the 152 isolates of V. cholerae speciated by kmer identification, 149 (98.1%) were concordant with the traditional biochemical approach. Traditional serotyping results were 100% concordant with the whole genome sequencing (WGS) analysis for identification of serogroups O1 and O139 and Classical and El Tor biotypes. ctxA was detected in all isolates of V. cholerae O1 El Tor and O139 belonging to sequence type (ST) 69, and in V. cholerae O1 Classical variants belonging to ST73. A phylogeny of isolates belonging to ST69 from UK travellers clustered geographically, with isolates from India and Pakistan located on separate branches. Moving forward, WGS data from UK travellers will contribute to global surveillance programs, and the monitoring of emerging threats to public health and the global dissemination of pathogenic lineages. At the national level, these WGS data will inform the timely reinforcement of direct public health messaging to travellers and mitigate the impact of imported infections and the associated risks to public health.
