It is mainly caused by an energy consumption greater than the animal’s requirement; and needs to be detected and faced accordingly because it negatively affects their well-being and longevity. Some important observations are; although it has been reported that depends on the composition of the diet, that dogs fed 2 times a day have lower blood glucose levels, as well as insulin levels showing the same tendency as glucose. Ghrelin and GLP1 concentrations are no different feeding 1 or 2 times a day. Energy expenditure through physical activity is important as it increases the rate of energy utilization and helps to raise the metabolic rate, which contributes to a comprehensive weight reduction program. Metabolic Energy Rate (MER) in sterilized dogs is lower than for intact animals; therefore, sterilization of pets increases the risk of obesity. The level of protein in the diet is important for promoting body protein synthesis and tissue repair. High protein diets work best when feed is offered ad libitum. Omega fatty acids reduce plasma concentrations of C-reactive protein and insulin. Dietary fiber helps to significantly reduce blood cholesterol and triglycerides.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":"1 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68126431","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}

Seven SNP were detected with a statistically significant effect (P < 0.01) on respiratory frequency under heat stress.

The ARS-BFGL-NGS-102407 SNP that is located in BTA 4 is the SNP that presents the highest number of associations to genes.

In this study, we hypothesized that feeding exclusively a corn stover-based diet (CSD), compared with one based on corn silage-oat hay, increases the abundance of the bacterial families and genera involved in cellulose and hemicellulose metabolism. For that purpose, we collected filtered ruminal fluid from six dry Holstein cows during two periods: Period 1, cows consumed a control diet based on corn silage and oat hay (CD), and in the Period 2, cows were fed CSD for 45 days. Ruminal fluid was collected through esophageal tubing. Ruminal microorganisms were identified by sequencing the 16S rRNA gene using the Illumina MiSeq platform. Compared with CD, feeding CSD for 45 days increased bacterial families and genera associated with higher neutral detergent fiber content and esterase and hemicellulolytic activities, such as Rikenellaceae, Prevotella, and Pseudobutyrivibrio. These results indicate that the liquid fraction of ruminal digesta contains a large number of microorganisms that help degrade lignocellulosic complexes, especially when diets with low-quality forages such as CSD are fed.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47810751","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}

It represents a large market for the Pharmaceutical Industry, and various combinations with frail pharmacological support have been made available to veterinarians. The crystalline sodium and potassium salts of BP-G and the benzathine salt of BP-G have been incorporated into many existing preparations, arguing that higher and more prolonged concentrations are obtained. However, there are not evidence published. Notwithstanding the above, these preparations are presented as sustained-release ones and capable of achieving therapeutic concentrations. There are no pharmacokinetic bases for such combinations of BP-G derivatives. It is unlikely that such combinations provide better serum profiles than those offered by an adequate dose of only procaine BP-G. The incorporation of the BP-G benzathine is prohibited in many countries. In Latin America, such combinations limit the amount of procaine BP-G that should be injected, ideally ≥ 20 000 IU/kg of body weight every 12-24 h. Within the framework of the rational use of antimicrobial drugs in veterinary medicine advanced by the World Health Organization (WHO) and based on pharmacological considerations, it is proposed that combinations of BP-G derivatives be restricted, allowing only BP-G procaine preparations. Also, formulations of BP-G incorporating other active principles should offer solid pharmacological support. To date, combined preparations of BP-G have shown no formal pharmacological support.

The frequency of livestock predation was found to be related to the abundance and availability of natural prey and the distance of ranches from the jaguar habitat. The interaction of the jaguar with humans presented an interesting and contrasting picture, since the perception of the jaguar varied depending on the sociocultural context and the study site. The results showed a negative effect of human activities on the distribution and density of the feline, and there was evidence of poaching and attacks on humans, although the information was insufficient to determine the causes in depth.
