13. Effect of creatine addition in feeds containing animal meals on the performance and carcass yield of broilers
The objective of this study was to evaluate the performance and carcass characteristics of broilers fed exclusively vegetable diets and diets containing animal meal with the addition of creatine or not after day 8. In the experiment, 1080 one-day-old male chicks were distributed according to a completely randomized experimental design into six treatments wit

14. Digestible methionine + cystine requirement for Nile tilapia from 550 to 700 g
This trial was conducted to determine the dietary digestible methionine + cystine requirement of Nile tilapia (550 to 700 g) based on the ideal protein concept. Six hundred fish were distributed in a completely randomized design with five treatments and four replicates, with 30 fish per experimental unit. The fish were fed diets containing approximately 262

15. Lysine and methionine + cystine for laying hens during the post-molting phase
One experiment was conducted to evaluate the effect of using different lysine and methionine + cystine levels on body weight recovery, performance, and egg quality of laying hens during the post-molting period. In this trial, 432 Isa Brown layers, with 72 weeks of age, were distributed in 54 cages according to a completely randomized design with six treatmen

16. Nutritional levels of digestible methionine + cystine to brown-egg laying hens from 50 to 66 weeks of age
The objective of this study was to determine the requirement of digestible methionine + cystine of brown-eggs laying hens from 50 to 66 weeks age at the end of the first production cycle. The design was completely randomized, with 150 Brown Shaver hens, which were distributed in five treatments with six replications of five birds each. Birds received a basal

17. Energetic and nutrient metabolizability values of corn obtained with nutritional corrections for broilers
The experiment was carried out to evaluate the influence of nutritional correction on the partial diet replacement or pure-food methodology to determine the energy values (apparent metabolizable energy - AME and nitrogen-correct apparent metabolizable energy - AMEn) and coefficient of metabolizability of nutrients of maize. The method of total excreta collec

18. NÃveis de isoleucina digestÃvel para suÃnos machos castrados dos 15 aos 30 kg / Levels of digestible isoleucine for barrows from 15 to 30 kg.
Aiming to determine the digestible isoleucine requirement for barrows from 15 to 30 kg, two experiments were conducted, being one of digestibility and another of performance. Ten crossbreed barrows with average initial weight of 15.00 Â 0.27 kg were used to determine the ileal digestibility coefficient of amino acids from basal diet. The animals were housed

19. NÃveis nutricionais de metionina+cistina digestÃvel para poedeiras semipesadas / Nutritional levels of digestible methionine + cystine to brown-egg laying hens
Com o objetivo de determinar a exigÃncia nutricional de metionina+cistina digestÃvel para poedeiras semipesadas no perÃodo de 50 a 66 e 75 a 90 semanas de idade, dois experimentos foram conduzidos no Setor de Pequenos Animais da Universidade TecnolÃgica Federal do Paranà - UTFPR, Campus de Dois Vizinhos - PR. Utilizaram-se 150 poedeiras Shaver Brown sem

20. Lysine nutritional requirements of broilers reared in clean and dirty environments during the pre-starter and starter phases
A total of 3,760 Ross male broiler chicks were used in two trials, one in the pre-starter (1-11 days) phase and the other in the starter (12-22 days) phase. Birds were distributed in a completely randomized experimental design with a factorial arrangement of 5 digestible lysine levels × 2 environments (clean and dirty environment), with eight replicates per

21. The use of animal byproducts in broiler feeds: use of animal co-products in broilers diets
This study aimed at evaluating live performance and carcass yield of broilers fed vegetarian diets or containing different animal byproduct meals after 8 days of age. In the experiment, 1080 one-day-old male chicks were distributed in a completely randomized experimental design with 6 treatments with 6 replicates. Diets were based on corn and soybean meal, a

22. Using the enzyme phytase in feed for laying Japanese quails / Uso da enzima fitase em ração para codornas japonesas em postura
There were two experiments to evaluate the effect of adding the enzyme phytase in the diet on the performance and eggs quality (experiment I) and the use of the feed ingredients (Experiment II) for laying Japanese quails. In the first experiment were used 320 quail females of Japanese sub- species, with 167 days old, initial weight of 182.3 + 3.8 g and rate

24. Crude protein reduction and digestible methionine+cystine and threonine to digestible lysine ratios in diets for fingerlings of Nile tilapia / Redução de proteína bruta e relações de metionina+cistina e treonina digestíveis com lisina digestível em dietas para alevinos de tilápia do Nilo
The current study was aimed at investigating the crude protein reduction and the methionine+cystine and threonine to lysine ratios, based on the ideal protein concept in diets for reverted Nile tilapia fingerlings (Oreochromis niloticus), of the thailand line. Four hundred twenty Nile tilapia fingerlings with an average initial weight of 1.83 0.02 g, were al
