Journal Article
Effect of dietary nano α-tocopherol acetate plus selenium on productivity, immune status, intestinal morphometry and carcass traits of broiler chicken
Background: Nano-vitamins and minerals are used in animal nutrition to improve performance and health of broiler chickens as a potential alternative to antibiotic growth promoters. Objective: To evaluate the effect of several levels of a dietary nano α-tocopherol acetate plus selenium compound…

Journal Article
Carcass yield, non-carcass components and economic viability of using licuri oil in the diet for Santa Inês ewe’s
Background: The production of biofuels has caused an increase in the prices of agricultural commodities. Thus, the ecological footprint, social inclusion and profitability of production systems have encouraged the use of agroindustrial products as an alternative in ruminant feeds. Objective: To…

Oxidative stress parameters in dogs naturally infected with sarcoptic mange
Background: Scabies is one of the most common diseases in dogs. It threatens both animals and humans due to its zoonotic potential. Objective: The purpose of this study was to evaluate the oxidant/antioxidant balance with hematological findings in dogs infested with sarcoptic mange. Methods: The…

Journal Article
Effects of ivermectin on cytokine and immunoglobulin levels in sheep
Background: Ivermectin may affect the levels of cytokines and immunoglobulins in sheep, considering that avermectins have an effect on the immune system. Objective: To determine whether ivermectin has an effect on cytokines and immunoglobulins in sheep. Methods: After administration of ivermectin…

Ivermectin use on pastured livestock in Colombia: parasite resistance and impacts on the dung community
Ivermectin (IVM) has been the most widely used antiparasitic agent in veterinary medicine since it came to the market in 1981. In its risk assessment, the American Food and Drug Administration (FDA) determined that, although it is very toxic to aquatic organisms, it is unlikely to contaminate…

Journal Article
Effects of phytase supplementation to reduced-nutrient diets on performance, egg quality, and economic parameters in commercial layers
Background: Exogenous enzyme supplementation is an effective and cost-saving mechanism for increasing the availability of dietary nutrients by increasing digestion and reducing excretion. Objective: To evaluate the effects of phytase supplementation on performance, egg quality, and economic…

Journal Article
Effect of the percentage of Bos taurus inheritance on the fertility of Holstein×Zebu and Brown Swiss×Zebu crossbred cows in the Mexican tropics
Background: No dairy breed or crossbreed has superior overall performance in all environments; therefore, it is necessary to determine which crossbreed is the most suitable for the Mexican tropic and what proportion of European breed is optimum for reproduction. Objective: To assess the effect of…

Journal Article
Comparison of mathematical models to estimate live weight through heart girth in growing Pelibuey sheep
Background: Assessment of animal growth based on live weight (LW) in traditional sheep production systems is limited by the high cost of purchase and maintenance of livestock scales. Objective: To develop and evaluate equations for LW prediction using heart girth (HG) in growing Pelibuey sheep…

Journal Article
Dairy goats fed sunflower hay intercropped with chickpea in small-scale systems. Part I: Animal performance
Background: Small-scale livestock systems provide quality food for a growing demand of animal protein worldwide. Although these systems help to improve rural living standards and reduce the environmental footprint new feeding strategies should be tested to improve animal productivity. Sunflower…

Journal Article
Asynchrony between in vivo and in vitro rabbit embryos
Background: Comparative features of embryos developed under in vitro and in vivo conditions are particularly important in designing embryo transfer procedures that fulfil embryo-recipient synchronization requirements. Objective: To determine the degree of asynchrony in rabbit embryo development…

Journal Article
Experimental protocol to repel opossums (Didelphis marsupialis) through an artisanal odor repellent device
Background: The human-opossum (Didelphis marsupialis) conflict has increased during the last decades mainly due to natural habitat loss, and mediated by generalist and opportunistic habits of opossums. A potential solution to reduce this conflict is to discourage the presence of opossums in human…

Journal Article
Bayesian threshold analysis of litter size in sheep
Background: Litter size at birth (LSB) is one of the most important economic traits in sheep and could be used in genetic improvement schemes for meat production. LSB is inherently a categorical trait and should be analysed with threshold models. Objective: Bayesian threshold models were used to…

Journal Article
Effect of iron-binding polypeptides and non-starch polysaccharides supplementation on growth performance and fecal scores of weaning pigs
Background: Weaning is the most stressful event in pig’s life, resulting in postweaning diarrhea and growth retardation. The supplementation of Advanced Digestion Enhancing Protein Plus Technology (ADEPPTTM), which contains iron-binding polypeptides and non-starch polysaccharides, to nursery diets…

Journal Article
Serum concentrations of corticosterone and sex hormones and their relationship in farmed Morelet’s crocodile (Crocodylus moreletii)
Background: Crocodile farming aims to produce high-quality skins from captive crocodilians. Captivity usually exposes the animals to stressful conditions, resulting in increased serum corticosterone (CORT) levels that correlate negatively with those of sex hormones and reproductive success…

Journal Article
Effect of tropical forage species in silvopastoral arrangements on methane production and in vitro fermentation parameters in a RUSITEC system
Background: Supplementation of grazing cattle with native and naturalized forages using silvopastoral systems has been suggested as an affordable strategy to reduce methane production and improve nutrition, diminishing the environmental impact of cattle production. Objective: To evaluate the effect…
