The global growing demand for food coupled with the direction of eating habits for products of animal origin, become even more necessary the search for alternatives to increase production. In this way, improve animal performance through the use of ionophores has become an effective measure to increase production and profitability of farms. Among the ionophores, monensin is the best known so far, as to their effect on the pattern of rumen fermentation and its consequences on animal production, especially by improving the quality or quantity of nutrients available for absorption through the gastrointestinal tract and consequently the performance of ruminants

The intensification of handling process is an attribute on modern swine, in animal agglomeration and total indoor, health problems become often, requiring pathology identification, as well most committed ages, in order to establish health programs in herd. Therefore the aim of this text is to discuss about major deseases wich reach the pork production

Gaseous losses are the main factors affecting the efficiency of nitrogenous fertilizers in pastures. To evaluate NH3-N volatilization losses in Tanzania grass fertilized with urea in autumn, spring and summer, a completely randomized design with repeated measurements over time and fifteen replicates was used. Plots were represented by urea levels (50; 100 and 150 kg ha-1 N) and subplots by time after fertilization (1; 2; 3; 6; 9; 12 and 15 days). The interaction between fertilization leveland time after urea application was significant for the accumulated NH3-N volatilization. Urea application leads to higher percentage N losses in the first three days after application. The average cumulative NH3- N loss for the three occasions (different seasons of the year) was 28%, 20% and 16% of N applied for fertilizer doses of 50; 100 and 150 kg ha-1 of N, respectively. The season of the year influenced NH3-N loss pattern and volume, with the lowest values recorded in spring, followed by summer and autumn. The cumulative NH3-N volatilization loss varies from 78 to 90% up to the third day after application of the total NNH3 loss.

The introduction of wool sheep in warm temperature regions of Brazil has also raised concerns regarding the warm stress and its consequent decrease in animal production. The understanding of the physiology of thermal balance in sheep, as well as the consequences of this phenomenon, should be studied in order to improve animal thermal comfort in association with the production and reproduction indices of these animals. The majority of available research findings related to thermal balance in sheep is derived from countries with temperate climates and therefore might be different from those performed in our climate conditions. This essay presents a literature review that intends to discuss this theme.
