ABSTRACT Objective: The objective of poultry breeder management is the production of fertilized eggs. The purpose of this study was to see how phytogenic feed additive (PFA) affected hatchable egg production in Cobb 430 Y breeders and the economic ramifications. Materials and Methods: In a broiler breeder farm in Bengaluru, a total flock size of 10,000 Cobb 430 Y breeders (58+ weeks old) were selected and equally distributed into two groups, viz. T1 and T2. The typical control and treatment groups were T1 and T2, respectively. T1 and T2 were reared on commercial feed, and T2 was simultaneously supplemented with PFA (500 gm/ton). Assessment parameters, such as hatchable egg production and economics of PFA usage, were determined. Results: In a broiler breeder farm, the hatchable egg production performance was enhanced by supplementing with PFA (500 gm/ton) for 7 weeks. Furthermore, the use of PFA resulted in a net profit of Indian rupees 20,000 for the broiler breeder farm owner. Conclusions: Under field conditions, PFA (500 gm/ton) is advised to promote hatchable egg production in Cobb 430 Y breeders.","PeriodicalId":185194,"journal":{"name":"Veterinary Research Notes","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121865138","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}

Small open-air houses are exposed to the disease, and the feed is the primary infection route that worsens the situation in many developing countries. In the modern poultry farming system, both feed conversion efficiency (feed to live weight or egg mass) and livability are vital. Both these characteristics are mainly dependent on the bird’s gut health. It is crucial to go over the specific aspects that influence poultry gut health and a description of nutritional manipulation to improve it for possible poultry production so that we can provide consumers with high-quality, safe animal protein. This review describes the updates on the manipulation of nutrition to improve the gut health of poultry.","PeriodicalId":185194,"journal":{"name":"Veterinary Research Notes","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124155067","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}

Colostrum samples were gathered on calving and the 5th day after calving. The concentration of major ingre¬dients [fat, protein, lactose, total solids (TS), solid-not-fat (SNF), and ash] changed significantly after birth, the day on 5, similar to normal milk. The average values of specific gravity, fat, protein, lactose, TS, SNF, and ash content of colostrum were observed on day 1 and day 5. \u0000Results: The specific gravity was 1.045 and 1.031, respectively. The fat, protein, and lactose con¬tents of colostrum on day 01 and day 05 after calving showed a significant difference. The compo¬sition of whole milk showed that the specific gravity was 1.029. According to the different stages of lactation, it was found that the protein, lactose, fat, TS, SNF, and ash content were lower in the first 2 months of lactation. After 3 months of lactation, it started to increase, and there was a significant change at the end of the sampling period. \u0000Conclusion: The composition of colostrum and milk of Holstein-Friesian crossbred cows was within the normal range, and the changing pattern was similar to the other dairy breeds.","PeriodicalId":185194,"journal":{"name":"Veterinary Research Notes","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131339618","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}

Staphylococcus spp., Escherichia coli, Salmonella spp., Proteus spp., and Citrobacter spp. were detected through cultural, morphological, and biochemical tests. The E. coli were identified by amplification of malB gene, and Staphylococcus aureus was identified by targeting 16r- RNA gene. The disc diffusion method was applied for the antibiogram investigation. Thin layer chromatography was performed to determine the antibiotic residue within the broiler meat. \u0000Results: Staphylococcus spp., E. coli, Salmonella spp., Proteus spp., and Citrobacter spp. were detected with a prevalence of 93.33% (42/45), 35.56% (16/45), 2.22% (1/45), 8.89% (4/45), and 13.33% (6/45), respectively. Antibiogram study revealed that Staphylococcus spp. showed the highest resistance to Trimethoprim and Oxytetracycline (75%), and the highest sensitivity was observed toward Gentamycin. The antibiogram profile of E. coli revealed 100% resistance to Oxytetracycline and 100% sensitivity to Gentamycin. Salmonella spp. showed resistance to Ciprofloxacin, Enrofloxacin, and Levofloxacin and was sensitive to Florfenicol and Gentamycin. The antibiotic profile of Proteus spp. exhibited 66.7% resistance to Trimethoprim, Ciprofloxacin, and Enrofloxacin. Citrobacter spp. showed 100% resistance to Trimethoprim, 66.7% resistance to Levofloxacin, and 100% sensitivity was observed to Florfenicol, Gentamycin, and Norfloxacin. The antibiotic residue of Ciprofloxacin, Levofloxacin, Oxytetracycline, and Enrofloxacin was also determined. In the case of antibiotic residue determination, the residue of Levofloxacin, Oxytetracycline, and Ciprofloxacin was found to be 6.67%, 6.67%, and 13.33%, respectively. \u0000Conclusion: This study revealed the existence of some multidrug-resistant pathogenic bacteria and higher limits of antibiotic residue in broiler meat and liver which may affect human health.","PeriodicalId":185194,"journal":{"name":"Veterinary Research Notes","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131378144","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}

Previously, the animal suffered from urinary inconsistence and dribbling-type urination. Physical palpation on the ventral aspect of the distended abdomen revealed a fluid-filled condition, and further needle aspiration confirmed the fluid to have a slightly alkaline pH resembling that of urine. The preputial manipulation and urinary catheterization were of no use for the obstruction. A light uremic smell was found in the animal’s breathing. Elevated blood urea nitrogen and creatinine were also detected. Clinically, it was assumed to be a ruptured urinary bladder (cystorrhexis) and subsequently diagnosed as a case of uroperitoneum (water belly). Paramedian laparotomic exploration was carried out to detect the ruptured part (perforation) of the bladder, and simultaneous expulsion of the accumulated peritoneal urine was done. A tube cystostomy was performed with Foley’s catheter to handle the case after repairing the perforated bladder (cystorrhaphy). In the postoperative phase, supportive medications and good management were ensured.\u0000Results: The calf recovered within 2 weeks of surgery and was found to maintain unremitting urine flow through the surgically fixed catheter. However, the calf was culled after 1 month of surgery.\u0000Conclusions: Tube cystostomy can be an effective approach for the management of water bellies in calves to save lives.","PeriodicalId":185194,"journal":{"name":"Veterinary Research Notes","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117030104","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}

This study investigates the status of the ALV in commercial poultry farms in Kaduna State, Nigeria. \u0000Materials and Methods: Two hundred and fifty sera samples were collected across five local governments in Kaduna State, Nigeria, between January 2017 and May 2018: Chikun, Lere, Kaduna North, Kaduna South, and Sabon Gari and were screened for ALV using the enzyme-linked immu¬nosorbent assay. \u0000Results: A total prevalence of 78.9% (CI: 73.4–83.53) was recorded. The highest prevalence of 82% (CI: 69.53–90.85) was recorded in a commercial poultry farm in Sabon-gari; 80% (CI: 67.24– 89.37), 78% (CI: 64.99–87.85), 78% (CI: 64.99–87.85), and 76% (CI: 62.77–86.3) were recorded for Kaduna North, Lere, Kaduna South, and Chikun commercial poultry farms. For layers, cockerels, and broilers, the detection rate was 86.5% (CI: 79.99–91.58), 75.0% (CI: 24.23–98.75), and 69.6% (CI: 60.66–77.62). At the age level, the highest rate was recorded in older birds, with 86.7% (CI: 74.32–94.41), while 77.1% (CI: 70.7–82.44) was recorded for the young birds, with no significant difference (p > 0.05) between the two age groups. \u0000Conclusion: The study indicated that ALV is prevalent in commercial poultry farms in Kaduna State, Nigeria. It was recommended that further studies be conducted on the molecular charac¬terization of the virus. Adequate preventive and control measures must be implemented because the economic impact of ALV on the poultry industry is enormous.","PeriodicalId":185194,"journal":{"name":"Veterinary Research Notes","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128962489","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}
