Milk samples of 78 first-lactation cows from 29 rural properties in the Planalto Norte Catarinense region were analyzed individually. The reference values for the analysis of fat and protein content were 4.0% and 3.3%, respectively. Logistic regression was used for analysis of the variables and the parameters were evaluated using odds ratios. Breed, age, gestation length, and grazing time are the variables that most influence the probability of producing milk with a protein content above 3.3%. Increasing milk production reduces the probability of obtaining milk with a fat content that allows the maximum bonus. Improvements in the cow’s body condition increase the probability of obtaining milk with a fat content that meets the industry’s requirements for maximum bonus.","PeriodicalId":43616,"journal":{"name":"BOLETIM DE INDUSTRIA ANIMAL","volume":"1 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2020-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41744051","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 generalized linear model methodology, GENMOD, was used with a probit link function to test the interaction of the questions with the socioeconomic profile and for all significant variables. The risk was calculated using the odd ratios (OR) with a confidence interval of 95%. Only age and education influenced consumers' disposition regarding the questions raised in the questionnaire. Most of the people who answered the questionnaire had never consumed any product packaged with MAP, but they are very interested in trying it out. Among consumers who had already consumed some product packaged with MAP, the vast majority consumed beef. Consumers over the age of 50 showed a greater tendency to consume beef with MAP more than once a week. Appearance was the main factor for decision making during the purchase and the supermarket is the main place of purchase of the product. The vast majority of consumers liked and would buy beef packed with MAP again.","PeriodicalId":43616,"journal":{"name":"BOLETIM DE INDUSTRIA ANIMAL","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2020-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48474779","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}

Analyzes of centesimal composition, microbiological composition and lipid oxidation through Thiobarbituric acid reactive substances (TBARS) were performed. There was a significant difference in moisture content, being higher for treatments with extracts, whereas the control treatment presented higher protein content. The fillets were within microbiological standards recommended by legislation. The values obtained from Malondialdehyde (MDA)/kg demonstrate the efficiency of natural antioxidants added. The use of plant extracts as natural antioxidants in sous vide has been shown to be an alternative to minimize oxidative rancidity of tilapia fillets, increasing shelf life. Thus, it is possible to use rosemary, oregano and basil extracts in the tilapia sous vide process.","PeriodicalId":43616,"journal":{"name":"BOLETIM DE INDUSTRIA ANIMAL","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2020-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44315520","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}

Thirty-six male Nelore cattle with 24 months old, from rearing in a continuous grazing system were divided into two groups of 18 animals (castrated and non-castrated) with initial mean body weight (iBW) of 347.5 kg ± 21.61 kg. The experimental design was a randomized complete block according to iBW for each sexual condition evaluated, constituting two experimental treatments: castrated animals and non-castrated animals. Each treatment consisted of six pens (3 animals/pen), these being considered the experimental units. The feedlot period was 112-days and the slaughter was carried out on the 113th day. The dry matter intake (DMI), average daily gain (ADG), feed conversion (F:G) and feed efficiency (G:F) were evaluated. In addition, the deposition of muscular and adipose tissue was evaluated by means of ultrasonography. After slaughtering of the animals the hot carcass weight (HCW), cold carcass weight (CCW) and carcass yield (YG) were determined. The data were analyzed using the PROC MIXED program from SAS and Tukey test (P ≤ 5%). There was no significant difference for the variables iBW and DMI in percentage of BW. The fBW, ADG, F:G and G:F variables had significant effects, and the group of non-castrated animals obtained a better productive performance. For the carcass traits evaluations, a significant difference was observed for HCW and CCW, where animals from the non-castrated group also had better carcass data. Therefore, it is concluded that for feedlot systems with high concentrate diets, castration of Nellore cattle is not recommended because it interfered negatively in the productive performance of the castrated animals.","PeriodicalId":43616,"journal":{"name":"BOLETIM DE INDUSTRIA ANIMAL","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2020-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48871865","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}

After electric sttuning of animals in a slaugtherhouse under SIF of the Zona da Mata region, Minas Gerais, stunning parameters were evaluated in 3,347 slaughtered swines.

The meat samples were evaluated for pH, Water Holding Capacity (WHC). Of the 3,347 slaughtered swines, 272 (8.13%) showed at least some sign of inadequate sttuning. It was observed that the 24 meat samples had mean pH of 6.06, mean loss water of 24.74% and mean score of 3.64 evaluated in color scale. The mean pH of meat obtained from animals improperly sttuninged (6.11) was greater (p<0.05) than the mean pH of animal properly sttuninged (6.01). The lower pH of meat causes lower color score and WHC (p<0.05). Therefore, the meat obtained from improperly sttuninged swine has a higher pH, which results in darker meat and low WHC.","PeriodicalId":43616,"journal":{"name":"BOLETIM DE INDUSTRIA ANIMAL","volume":"7 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67513794","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}
