The rearing of pigs in the mountains of Papua is generally based on the free-range method during the daylight. Poor environmental sanitation and free-range management have been reported as risk factors of gastrointestinal worm infestation in pigs. In general, gastrointestinal parasite infestation can cause a loss of appetite, impede growth, decrease feed conversion rate, and increase vulnerabilities toward other pathogens. To add to that, the acute levels of infestation can cause death. Furthermore, some species can infest humans (zoonotic). As zoonotic parasites can impact the productivity and health of the people, it is crucial to identify the species of such parasites. This research was conducted in Umpakalo village at Kurulu district, Jayawijaya region, and three other villages namely Obaipugaida, Eyagitaida, and Ugituwataida at Ekadide district, Paniai region. Forty-five fecal samples from different pigs were used as the research material. The native method was used to identify the physical appearance of the eggs, and in turn, identify the species of the parasite. The data was analyzed in the tabulation form. The conclusion obtained in this research is that 95% of the fecal samples were infected by the gastrointestinal worms. Identified worms are Ascaris suum, Strongyloides ransomii, Trichuris suis, and Strongyle types. Most pigs have mixed infections.

The Impact

Background: Gastrointestinal (GI) parasitism in pigs is often associated with subclinical infections leading to poor weight gain and reduced market value. One of the most significant risks is pigs being the host for many zoonotic parasites and thereby threatening human health. Despite the epidemiological data being available from different states of the country, records from Andhra Pradesh are scanty. Hence, a study was conducted to determine the prevalence of gastrointestinal parasites in free range pigs of Proddatur municipality Andhra Pradesh, India. Methods: About 142 fecal samples were collected from free range pigs slaughtered in four localities of Proddatur municipality over a period of six months. The fecal samples were later subjected for parasitological examination and the tissue pieces of intestines collected from the slaughtered animals with the embedded parasites and those with pathological changes were subjected to histological staining procedure for identification. Result: Fecal examination revealed 80.98% (115/142) positivity for parasitic ova or occysts. About eleven species of parasites were identified; of them nine were helminths (83.8%) and two were protozoan (10.5%) parasites. Infection with Ascarops spp. (28.2%) and Fasciolopsis buski (17.6%) was found to be significantly (P less than 0.05) higher. The tissue sections of the intestines with pathological lesions revealed embedded parasites in intestinal mucosa infiltrated with eosinophils and mononuclear cells. The higher prevalence of GI parasites in slaughtered pigs in Proddatur region rises concern towards the impact on the health of pigs and as well as pork consumers suggesting a strategic control for GI parasites in pig farming.

AbstractThe aim of the study was to assess the effect of fermented dried soybean (FSBM) and/or fermented rapeseed meal (FRSM) in diets for weaned piglets on production results, nutrient digestibility, gastrointestinal tract histology, and the composition of the gut microbiota. Piglets in the control group received standard diets with soybean meal. Animals in all experimental groups received diets in which a portion of the soybean meal was replaced: in group FR—8% FRSM; in group FR/FS—6% FRSM and 2% FSBM; in group FS/FR—2% FRSM and 6% FSBM and in group FS—8% FSBM. The use of 8% FRSM or 6% FRSM and 2% FSBM in the piglet diets had a positive effect on average daily gains. Piglets from the FR and FR/FS groups had the highest feed conversion rate. Group FS/FR and FS piglets had significantly lower mortality and lower incidence of diarrhoea. Piglets fed a diet with the fermented components, in particular with 8% FRSM or 6% FRSM and 2% FSBM, exhibited a positive effect on the microbiological composition and histology of intestines, which resulted in improved nutrient digestibility coefficients (ATTD and AID).

Abstract Background The development and utilization of probiotics had many environmental benefits for replacing antibiotics in animal production. Bacteria in the intestinal mucosa have better adhesion to the host intestinal epithelial cells compared to bacteria in the intestinal contents. In this study, lactic acid bacteria were isolated from the intestinal mucosa of broiler chickens and investigated as the substitution to antibiotic in broiler production. Results In addition to acid resistance, high temperature resistance, antimicrobial sensitivity tests, and intestinal epithelial cell adhesion, Enterococcus faecium PNC01 (E. faecium PNC01) was showed to be non-cytotoxic to epithelial cells. Draft genome sequence of E. faecium PNC01 predicted that it synthesized bacteriocin to perform probiotic functions and bacteriocin activity assay showed it inhibited Salmonella typhimurium from invading intestinal epithelial cells. Diet supplemented with E. faecium PNC01 increased the ileal villus height and crypt depth in broiler chickens, reduced the relative length of the cecum at day 21, and reduced the relative length of jejunum and ileum at day 42. Diet supplemented with E. faecium PNC01 increased the relative abundance of Firmicutes and Lactobacillus, decreased the relative abundance of Bacteroides in the cecal microbiota. Conclusion E. faecium PNC01 replaced antibiotics to reduce the feed conversion rate. Furthermore, E. faecium PNC01 improved intestinal morphology and altered the composition of microbiota in the cecum to reduce feed conversion rate. Thus, it can be used as an alternative for antibiotics in broiler production to avoid the adverse impact of antibiotics by altering the gut microbiota. Graphic Abstract

By Products

As insect farming is becoming more popular in Europe and in the US, the use of food industry by-products in insects’ feed is drawing more attention. However, it is still unclear how to maximise the use of by-products in the feeds while meeting the nutritional requirements and maintaining profitable rearing yields with the current production technology. In this study, we conducted an experiment in Finnish small-scale cricket farming and laboratory conditions to determine whether five diet treatments, including by-product diets with barley mash and turnip rape, modify the overall fresh yield (kg), development time and feed conversion rate of the house crickets (Acheta domesticus). We discovered that the diets differed in the overall fresh cricket yield (kg) but not in the development time or the feed conversion rate of the crickets. The diets with a high proportion of by-product decreased the price of the feed but at the same time reduced the yield. Based on our results, complex by-product diets with the by-product proportion of 20-41% are the most suitable for house cricket rearing.

The performance of Nile tilapia (Oreochromis niloticus) raised in cages furnished with an automatic dispenser, supplied at different frequencies (once per hour and once every two hours) and periods (daytime, nighttime and both) was evaluated. Eighteen 1.0m³ cages were placed into a 2000m² pond, two meters deep with a 5% water exchange. One hundred and seventy tilapias, with initial weight of 16.0±4.9g, were dispersed into each 1m³ cage and the feed ration was adjusted every 21 days with biometry. Data was collected from March to July (autumn and winter). Significant difference to final weight (P<0.05) among treatments was observed. The increase in feeding frequency improves the productive performance of Nile tilapias in cages and permitted better management of the food. The better feed conversion rate for high feeding frequency (24 times day-1) can result in saving up to 360kg of food for each ton of fish produced, increasing the economic sustenance for tilapia culture and suggesting less environmental pollution.

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

Probiotic effects on growth performance, carcass traits, blood parameters, cecal microbiota, and immune response of broilers were studied. Two hundred one-day-old male chickens were allocated to one of five treatments (four replicates of 10 birds per treatment): control, and the same control diet supplemented with 0.005%, 0.01%, 0.015% and 0.02% probiotics. Probiotics in feed at 0.01% or higher levels of supplementation improved body weight gain (+12%) and feed conversion rate (-5%) compared with the control. There were no effects on carcass traits, but the relative weights of drumsticks and wings showed increasing and decreasing linear responses, respectively, to probiotic supplementation level. Blood plasma glucose and albumin contents linearly increased (from 167.1 to 200.5 mg dl-1, and from 1.70 to 3.25 g dl-1) with increasing probiotic supplementation. Triglycerides and cholesterol contents were lower in probiotic supplemented treatments (average contents 71.3 and 125.3 mg dl-1 vs. 92.6 and 149.9 mg dl-1 in the control). Probiotics decreased cecal Escherichia coli counts, but had no effects on immunity related organs or immune response. The linear trends, either positive or negative, observed in many of the parameters studied, suggest that more studies are needed to establish the optimal concentration of probiotics in broiler feed.

As an important tool for systematic analysis, genome-scale metabolic network (GSMN) model has been widely used in various organisms. However, there are few reports on the GSMNs of aquatic crustaceans. Litopenaeus vannamei is the largest and most productive shrimp species. Feed improvement is one of the important methods to improve the yield of L. vannamei and control water pollution caused by the inadequate absorption of feed. In this work, the first L. vannamei GSMN named iGH3005 was reconstructed and applied to the optimization of feed. iGH3005 was reconstructed based on the genomic data. The model includes 2,292 reactions and 3,005 genes. iGH3005 was used to analyze the nutritional requirements of five different L. vannamei commercial varieties and the genes influencing the metabolism of the nutrients. Based on the simulation, we found that tyrosine-protein kinase src64b like may catalyze different reactions in different commercial varieties. The preference of carbohydrate utilization is different in various commercial varieties, which may due to the different expressions of some genes. In addition, this investigation suggests that a rational and targeted modification in the macronutrient content of shrimp feed would lead to an increase in growth and feed conversion rate. The feed for different commercial varieties should be adjusted accordingly, and possible adjustment schemes were provided. The results of this work provided important information for physiological research and optimization of the components in feed of L. vannamei.

Common Parasite

Paramphistomum and Fasciola are the most common parasite found in the gastrointestine of the cattle in the terai region of Nepal. The parasite resides in the gut and feed there, resulting in the nutrition deficit for the cattle. A study was conducted in Kohalpur, Banke of Nepal to study the seasonal and breed-wise prevalence of the gastrointestinal parasite in cattle. A total of 156 fecal samples were analyzed, out of which 79 samples were collected in summer and 77 samples were collected in winter. Out of total samples 108 were brought to the clinic and 48 samples were collected directly from the rumen of the cattle. Sedimentation technique for recovering the larva and egg of parasite was performed. Five slides were prepared from each sample and was observed under the microscope for eggs and larva. The result showed that the prevalence was 36.71% in the summer and it was 16.88% in the winter. The statistical relationship showed that the prevalence gastrointestinal parasite in cattle was significantly (P<0.05) higher in the summer season. Likewise, the prevalence was 11.86% in the Jersey breed and 36.08% in the Jersey cross breed. And the statistical relationship also showed that the gastrointestinal prevalence in Jersey cross breed was significantly (P<0.05) higher than Jersey breed.
