25. Use of Organic Acids and A Competitive Exclusion Product as Growth Promoter and Salmonella Enteritidis Control in Commercial Turkeys
ABSTRACT It is estimated that Salmonella causes one million illnesses in the United States annually, with 19,000 hospitalizations and 380 deaths. There are various serotypes of this bacterium, and the serotypes Typhimurium and Enteritidis are commonly isolated from outbreaks and, in most cases, present resistance to the antibiotics utilized in clinical medic

26. Environment, facilities, and management of hospital pens in growing and finishing pig farms: a descriptive study
ABSTRACT The objective of this study was to describe the housing system in the hospital pens on growing and finishing (GF) pig farms. This work was developed by using a questionnaire and was conducted between January and April, 2016. Forty-four GF commercial farms (a total of 41,111 animals) were involved, seeking to raise issues concerning the facilities of

27. The Effects of Different Amount of Protein and Vitamin e Supplementation in Rations on Lipid and Antioxidant Metabolism of Broilers Exposed to Heat Stress
ABSTRACT Heat stress, causes economic losses and has negative effects on both broiler husbandry and animal welfare. Nutritional strategies are applied for minimizing the negative effects of heat stress. In the present study, at the finishing period (24-39 days of age) of heat stress, the effects of diet involving 21% and 19% proteins and vitamin E on lipid m

28. Enzyme complex supplementation in different nutrient levels diets on pigs feces excretion and anaerobic digestion
ABSTRACT This research aimed to evaluate enzyme supplementation in diets with different nutritional levels for pigs in their feces excretion and anaerobic digestion. Fifty four gilts were placed on diets formulated to achieve 100 or 95 or 90 % of a pig's nutrient requirements, with the addition of an enzyme complex containing amylase, β-glucanase, cellulase

29. A glimpse of the future in animal nutrition science. 2. Current and future solutions
ABSTRACT Despite tremendous advancements in the livestock sector, additional opportunities exist to improve even further livestock production around the globe. Forecasting is not an exact science and it relies heavily on past and current knowledge. Improvements in the nutritional sciences (both human and animal) include a better understanding of agents that

30. Avaliação da eficácia da lasalocida e de alguns fatores epidemiológicos de Eimeria spp. parasitando bezerros Nelore mantidos em regime de pastejo
RESUMO: A principal importância da eimeriose em bovinos, se deve ao baixo desempenho produtivo que os animais demonstram quando esta enfermidade apresenta-se sob a forma sub-clínica. Como objetivos, o presente trabalho avaliou a eficácia do uso da lasalocida sódica contra espécies de Eimeria spp. parasitando bezerros; avaliou também o desempenho ponder

31. Phenotypic association between feed efficiency and feeding behavior, growth and carcass traits in Senepol cattle
ABSTRACT The objective of this study was to evaluate the associations between feed efficiency and feeding behavior, growth and carcass traits in Senepol cattle. A total of 137 animals were evaluated. Of these animals, 36 males were evaluated in a second test, totaling 173 records (initial age of 466±96 days and initial weight of 426±104 kg). Residual feed

32. Fusarium and Aspergillus mycotoxins contaminating wheat silage for dairy cattle feeding in Uruguay
Abstract Wheat is one of the most important cultivated cereals in Uruguay for human consumption; however, when harvest yields are low, wheat is usually used in ensiling for animal feeding. Ensiling is a forage preservation method that allows for storage during extended periods of time while maintaining nutritional values comparable to fresh pastures. Silage

33. Predatory behavior of three centipede species of the order Scolopendromorpha (Arthropoda: Myriapoda: Chilopoda)
ABSTRACT Studies related to centipede feeding and predatory behavior are rare in the literature, and are limited to observations made during fieldwork. Furthermore, they lack descriptions of prey capture. We conducted a laboratory experiment using South American specimens of Scolopendra viridicornis Newport, 1844 (n = 5), Otostigmus tibialis Brölemann, 1902

34. Effects of lines and inoculants on nutritive value and production costs of triticale silages
ABSTRACT The current study was undertaken to investigate the ensilage characteristics in triticale lines treated by inoculants and their interaction on fermentation metabolites and rumen degradability. Costs were estimated for growing and feeding whole-crop triticale lines for animal production. Triticale hybrids were harvested at the dough stage of maturity

35. Conjugated linoleic acid of dairy foods is affected by cows’ feeding system and processing of milk
ABSTRACT The distribution of conjugated linoleic acid (CLA) in dairy products commercially available in Chile is poorly understood. This study aimed to assess the content of CLA in dairy cow products from Chile and the effect of processing fresh milk into dairy products. Samples of raw milk were categorized into two groups based on the animal feeding system

36. A survey of dairy calf management practices in some producing regions in Brazil
ABSTRACTThis study aimed to characterize the Brazilian dairy calves raising systems through a survey of major aspects of animal husbandry. One hundred seventy-nine producers and/or technicians were interviewed. The questionnaire addressed issues related to the management of the dry cow and the newborn, nutritional management of the liquid-feeding phase, hous
