The present study evaluated the efficacy of a PFA in broiler chickens diets on growth performance and digestibility parameters. A total of 880 male one-day-old broiler chickens (Ross 308) were randomly assigned to two dietary treatments, each with 20 replicates and 22 chickens per replicate. A corn-soybean-based diet was fed for 42 days as a control diet without PFA, and a treatment diet containing a blend of Carvacrol, Thymol, Carvone, Methyl salicylate, and Menthol encapsulated (as PFAs) at 65 g/ton of feed. Chickens supplemented with PFA had a 3.6% higher Body Weight Gain (BWG) during the starter phase (0 to 14 days) than those in the control group (25.9 versus 25.0 g/d) and a 2.9% reduced Feed Conversion Ratio (FCR) during the same period, compared to the control group (1.34 versus 1.38). Improved FCR (1.95 versus 2.01) was recorded in the PFA supplemented broiler chickens during the finisher phase (35 to 42 days) as well as throughout the experimental period from 1 to 42 days, compared to the control group (1.60 versus 1.62). In addition, the apparent ileal protein digestibility improved by 3.9% during 42 days, compared to the control group (74.3 vs 71.5%; P = 0.0428). Enhanced ileal protein digestibility and a reduced FCR suggested a cost-effective potential of PFA to improve broiler chickens’ production performance.","PeriodicalId":290171,"journal":{"name":"Journal of World's Poultry Research","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114368870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of the current study was to explore the micropathology of the duodenum, jejunum, caecum, liver, lung, spleen, kidney, adrenal gland of Japanese quails naturally infected with. E. tenella. The histopathological examination revealed that developmental E. tenella led to the damage of caecal, duodenal, and jejunal. Necrosis and desquamation of the integumentary epithelium, atrophy of crypts and folds, hemorrhages, lymphoid infiltration were confirmed in the mucous membrane of these intestines. The main changes observed in the parenchymal organs involved the fatty dystrophy of hepatocytes and lymphoid infiltration of parenchyma of the liver, stagnant hyperemia and edema of the lungs; granular dystrophy and necrosis of epithelial cells of the collecting ducts of the kidneys, venostasis of blood sinusoids of the spleen, hyperplasia of interrenal tissue, and dystrophia of suprarenal tissue of the adrenal gland. Morphometric studies have shown that pathological changes in the organs of quails infected with E. tenella led to a decrease in the thickness of the caecal mucosa, volume of the parabronchial lumen of the lung, and the number of renal corpuscles of the infected group, compared to the control group. The indicators of the interrenal-adrenal index of the adrenal glands, the number of clusters of lymphoid cells of the liver, and lymphoid nodules of the spleen increased. The received information could offer deep insights about pathogens in quails coccidiosis and can be used for planning therapeutic measures.","PeriodicalId":290171,"journal":{"name":"Journal of World's Poultry Research","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121757959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To obtain high-energy feed, there is a need to use the germinated grain as one of the components for the extrusion used in animal food processing. The quality assessment of the extruded feed in terms of environmental and energy indicators based on a two-component mixture is of particular interest. In this regard, the purpose of the present research was to identify the regularities of changes in metabolic energy and the ecological-energy indicator of the feed quality, depending on the quantitative and qualitative content of the germinated component included in the extruded mixture. Wheat was mixed for 72 hours with pre-germinated grains of wheat, rapeseed, peas, oats, soybeans, or corn. The resulting mixture was extruded at a temperature of 120-130°C and pressure of 4-5 MPa. The highest metabolic energy of the feed was found in the extruded mixture containing 25% sprouted grains of soybeans, rapeseed, corn, peas, oats 15%, and wheat 10%. Regarding energy indicators, it is advisable to use 25% of the sprouted grain of soybeans, rapeseed, corn, peas, 15% of oats, and 10% of wheat in the extruded mixture as well as 10% of sprouted wheat, 25% peas, 25% corn, 10% soybeans, 20% oats, and 10% rapeseed. Based on the obtained results, a mathematical model was designed using the theory of splines. The modeling was carried out in the Maple package.","PeriodicalId":290171,"journal":{"name":"Journal of World's Poultry Research","volume":"213 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121346967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the present study was to determine the effect of in-ovo injection of cinnamon, thyme, and clove extracts on the subsequent growth performances, immunity, and physiological responses of newly-hatched chickens. A total of 450 fertile eggs used in the current experiment were obtained from avian broiler breeder flocks of 28 weeks of age. The eggs were randomly distributed into five treatment groups which included three replicates for each one (30 eggs each group) in a completely randomized design at day 10 of embryogenesis. Treatment groups included a control group (P1: without any injection), the group received an injection of 0.5 ml deionized water (P2: sham group), and the groups injected with 0.1 ml cinnamon, thyme, and clove extracts (P3, P4, P5, respectively). The hatchlings from each treatment were randomly assigned to five replicates of 10 chickens, and reared until 35 days of age. The results showed no significant differences among groups in terms of feed consumption, serum albumin, and immunoglobulin’s A (IgA). Nevertheless, using extracts resulted in a significant increase in body weight and weight gain, and improved feed conversion ratio and immunoglobulin’s G and M (IgG and IgM), compared to the control and sham groups at 35 days of age. The injected extracts had significantly positive effects on serum lipids profile, liver functions (AST, ALT, and ALP) values, and antioxidant activity, compared to the control groups. Furthermore, serum concentrations of triiodothyronine and thyroxine were significantly higher in the group injected clove-extracted than in other experimental groups. According to the results, it can be concluded that in-ovo injection of herbal extracts, especially clove extract on day 10 of incubation has a positive effect on the broiler chickens’ weight at hatch and post-hatch performance as well as physiological, immunological, and anti-oxidative status of hatched chickens.","PeriodicalId":290171,"journal":{"name":"Journal of World's Poultry Research","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123495740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breeding programs are powerful strategies to improve these economic traits. The challenge, however, is to choose an appropriate strategy to increase production. The estimation of genetic parameters in target strains could provide valuable information to determine the potent breeding strategy. Therefore, the aim of the current study was to assess the heritability and the genetic correlations of the Body Weight (BW), Body Dimensions (BD), and Carcass Traits (CT) in four Egyptian strains (Matrouh, Mandarah, Inshas, and Silver Montazah) of dual-purpose chickens. The BW was measured at hatching (BW0), 8 weeks (BW8), and 16 weeks (BW16) of age, and weight gain was calculated from 8 to 16 weeks of age. The BD traits included shank length (SL), keel length (KL), and Body Circumference (BC). Carcass, liver, gizzard, heart, head, and leg percentages were also determined. Data were collected on 2800 dual-purpose chickens with pedigree information. A Multitrait animal model with a restricted maximum likelihood procedure was applied to estimate heritability, genetic and phenotypic correlations for BW, BD, and CT using Wombat software. Heritability estimates for BW traits were between 0.24 and 0.41 for BW0 and BW8, respectively. Heritability estimates of SL, KL, and BC were 0.49, 0.41, and 0.52, respectively. The heritability estimates for CT were low to moderate, ranging from 0.15 to 0.37 for head and gizzard percentage, respectively. The least-square means for BW, BD, and CT varied significantly between strains. The genetic correlation estimates among BW and BD traits indicated a close genetic relationship between these traits. Positive genetic correlations were found between BW and BD with CT (from 0.12 to 0.78). Based on the present results, there were strong positive genetic correlations between all traits, including BW and BD as the most important ones. Therefore, the selection for these traits would improve the carcass traits in the four strains of chickens. Hence, the inclusion of BW and BD as selection criteria in breeding programs would potently affect the improvement in carcass performance, which might positively increase the production profit of such strains.","PeriodicalId":290171,"journal":{"name":"Journal of World's Poultry Research","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133584336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
