In total, 180 one day-old native chicks were assigned to one of three dietary groups (60 birds each). The control group (Group A) received the basal diet. In addition to the basal diet, the two experimental diets (Groups B and C) were supplemented with 0.2% and 0.4% rosemary complex powder, which contained rosemary leaves, sweet basil, pineapple sage and sweet lavender. Over 19 weeks, feed intake was recorded to determine the average daily gain and feed conversion ratio. In weeks 10 and 15, blood samples were taken for serum antibody titer analysis. At the end of the experiment, serum immunoglobulin A (IgA) and serum immunoglobulin G (IgG) concentrations were examined. No differences were observed among the groups in terms of the starting weight, weight in week 19, average daily feed intake, average daily gain, or average feed conversion ratio. The addition of rosemary complex powder improved total weight gain by 1.52%. Serum IgA and serum IgG concentrations were significantly lower in the experimental groups in comparison to the control group ( p <0.05). Villus height, villus width, crypt depth, and villus height/ crypt depth ratio were significantly higher in group B than in group A ( p <0.05). In summary, rosemary complex powder improved the intestinal absorption capacity of chickens and significantly reduced their immunoglobulin concentrations.","PeriodicalId":9244,"journal":{"name":"Brazilian Journal of Poultry Science","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67655031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of two hundred 1-day-old male Ross 308 chickens were allocated in a 2 × 2 randomized factorial design. Diets included 2 PFPO levels (0 and 50%) and 2 CaSPO levels (0 and 50%). The level was the percentage of substitution of VO by granulated fats. The study had two phases (starter and finisher), each lasting 21 days. In the starter phase, PFPO did not influence (main effects; p >0.05) feed intake and body weight gain, but improved (main effect; p =0.03) feed conversion. In the finisher phase and the total study, PFPO had no effect ( p >0.05) on these productive variables. Throughout the study, CaSPO did not influence feed intake (main effect; p >0.50), but decreased weight gain and had a negative effect on feed conversion (main effects; p <0.05). There was no influence of fats (PFPO or CaSPO) on carcass yield, breast, drumsticks plus thighs, and wings (main effects; p >0.05). Chickens fed CaSPO had lower (main effect; p =0.02) carcass weight. The only PFPO × CaSPO interaction ( p =0.04) was for back yield. Results showed that PFPO or CaSPO could be employed in formulating broiler chicken diets, as they are less expensive than conventional VO. Partial substitution of VO for PFPO had minimal effect on productive variables, although partial dietary inclusion of CaSPO might slightly reduce the production of broiler chickens.","PeriodicalId":9244,"journal":{"name":"Brazilian Journal of Poultry Science","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67654860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 180 0-day-old Pekin ducks were allocated randomly between three dietary groups viz., control, Treatment 1, and Treatment 2, with three pens per group and twenty birds per pen, characterized by increasing levels of pelleted TM powder with CBP meal in concentration of 0%, 1.5%, and 3%, respectively, and reared until 42 days of age in a completely randomized design. On day 42, the ducks were sacrificed, and breast and thigh muscles were used for meat quality evaluations. Feeding pelleted TM powder with CBP meal resulted in a significant difference in final body weight, weight gain and feed conversion ratio ( p <0.05). Additionally, a significant difference was observed in the pH of the breast meat samples ( p <0.05). As the only significant difference between the breast and thigh meat, 1,1-diphenyl-2-picryhydrazyl radical scavenging was influenced significantly by the dietary inclusion of pelleted TM powder with CBP meal ( p <0.05). However, the values of thiobarbituric acid reactive substances and meat color in both breast and thigh meat were insignificant ( p >0.05) different among all groups. To conclude, the inclusion of up to 3 % of pelleted TM powder with CBP meal in the diets of ducks did improve the growth production and antioxidant characteristics effects, which could decrease TBARS and reflected by changes in 1,1-diphenyl-2-picrylhydrazyl free DPPH radical scavenging values.","PeriodicalId":9244,"journal":{"name":"Brazilian Journal of Poultry Science","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67655481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we aimed to describe the growth curve of chickens of the Canela-Preta breed reared in two different rearing systems, considering their different plumage colors. Initially, 204 one-day-old male and female chicks were randomly distributed in confinement and semi-confinement (102 animals in each system) without separation by gender. The animals were individually identified by wing and foot plastic brands and were weighted every seven days. The body weight and age records were used to estimate the growth curves of the following factors using the Richards model: plumage color, gender, and rearing system. The likelihood ratio test was used to verify the equality of parameters and identify nonlinear models to compare the growth patterns of the evaluated groups. The growth pattern of Canela-Preta chickens changed as a function of gender, plumage color, and rearing system. Females with black plumage, black and gold hens, and males with black and white plumage showed greater sensitivity to changes in rearing systems. Within-breed selection strategies for specific colors can improve the use of growth pattern differences, improving production efficiency. Semi-confinement is suitable for rearing Canela-Preta chickens with any plumage color, as these animals meet the free-range poultry niche market requirements.","PeriodicalId":9244,"journal":{"name":"Brazilian Journal of Poultry Science","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67652655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They also have a wide range of pharmacological activities including – antiarrhythmic, antioxidant, antimalarial, vasodilatory, antimicrobial, analgesics, hepato-protective, anti-inflammatory, hypo-cholesterolemic, anti-androgenic, antiviral, antifungal and immune-modulatory. This study was carried out to investigate the bioactive compounds of Prosopis africana oil (african mesquite) using gas chromatography – mass spectrometry technique. A total of 73 bioactive compounds 77.16% were identified based on their peak areas. The major compounds identified in the oil sample were; prosogerin A 29.90%, caryophyllene 12.33%, 2,4-bis (1-phenylethyl) phenol 5.80%, gallic acid 5.22%, β-cyclocitral 3.11%, β-sitosterol 2.50%, α-terpinene 2.09% and ellagic acid 2.04%. The other compounds were less than 1%, however, they exert various pharmacological properties.
