13. 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

14. A glimpse of the future in animal nutrition science. 1. Past and future challenges
ABSTRACT If the world population continues to increase exponentially, wealth and education inequalities might become more pronounced in the developing world. Thus, offering affordable, high-quality protein food to people will become more important and daunting than ever. Past and future challenges will increasingly demand quicker and more innovative and effi

15. 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

16. Phosphorus fractions in soil with a long history of organic waste and mineral fertilizer addition
ABSTRACT Applications for long periods of organic animal waste as a source of nutrients to crops can contaminate the soil and the surface and subsurface waters. This study aimed to evaluate how the utilization of organic waste, after successive applications, affects P fractions in the soil and consequently environmental contamination. In an experiment conduc

17. Nutritional and microbiological quality of bovine colostrum samples in Brazil
ABSTRACT The objective of this study was to evaluate the nutritional and microbiological composition of colostrum samples collected from colostrum banks or newly calved cows on dairy farms. For this purpose, 66 colostrum samples from dairy cows were directly collected during the milking of newly calved cows or from colostrum storage bank. Samples were collec

18. Gonadosomatic index and some hematological parameters in African catfish Clarias gariepinus (Burchell, 1822) as affected by feed type and temperature level
ABSTRACT The purpose of the current study was to examine the effects of different feeds/nutrients and temperature on the gonadal development of Clarias gariepinus. The gonadosomatic index (GSI) and blood parameters including red blood cell count (RBCs), white blood cell count (WBCs), hemoglobin (Hgb) level, hematocrit (HCT), platelets (PLT) and mean corpuscu

19. Determination of thermal comfort zone for early-stage broilers
ABSTRACT Environmental temperatures currently considered within comfort zone for broiler rearing may be misleading or even obsolete from actual values. Some factors such as animal genetics, nutrition and poultry management, mainly acclimatization to tropical and subtropical conditions, influence in determining the comfort zone for birds. This study aimed to

21. Development of an L-Lysine Enriched Bran for Animal Nutrition via Submerged Fermentation by Corynebacterium glutamicum using Agroindustrial Substrates
L-Lysine is an essential aminoacid added as supplement for animal feed. The aim of this work was to produce an L-Lysine enriched bran using Brazilian agroindustrial byproducts. Both the raw material costs and purification steps were minimized. Firstly, medium composition for the growth of Corynebacterium glutamicum ATCC 21799 was optimized targeting enhanced

22. The Effect of Jatropha Curcas Seed Meal on Growth Performance and Internal Organs Development and Lesions in Broiler Chickens
ABSTRACT The meal of Jatropha curcas (JCM) seed is a by-product of the biofuel industry and may potentially to be used as animal feed. However, its toxicity has prevented its utilization in animal nutrition mainly due to its high concentration of phorbol esters. This study was conducted to evaluate the effects of the dietary inclusion of JCM on the growth pe

23. Models of protein and amino acid requirements for cattle
Protein supply and requirements by ruminants have been studied for more than a century. These studies led to the accumulation of lots of scientific information about digestion and metabolism of protein by ruminants as well as the characterization of the dietary protein in order to maximize animal performance. During the 1980s and 1990s, when computers became

24. Effects of dietary lysine on broiler performance and carcass yield - meta-analysis
There has been a great evolution and improvement in the nutrition of poultry and lysine has been used the reference amino acid to increase animal protein deposition. Therefore, a meta-analysis was performed with the objective of studying the effect of different dietary lysine levels on the performance and carcass yield of broiler chickens. In total, 21 studi
