1. Metabolisable energy prediction in energy feedstuffs and evaluation of the stepwise validation procedure using bootstrapping
RESUMO A utilização de valores preditos de energia metabolizável aparente (EMA), obtidos a partir de equações de regressão, pode ser útil para instituições de pesquisa e indústrias de nutrição. Contudo, há a necessidade de validação em amostras independentes para assegurar que a equação de predição da EMA seja confiável. Neste estudo, for

2. Application of a precision nutrition tool for growing and finishing pigs
ABSTRACT The objective of this study was to evaluate a growth model applied to adjust nutritional programs for growing and finishing pigs, in a commercial production context. The phase I (calibration) was conducted in a commercial pig production unit. The data were collected from a nutritional program, a feed program, and an animal profile. In experimental p

3. 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

4. Characterization and influence of production factors on growing and finishing pig farms in Brazilian cooperatives
ABSTRACT The objective of this study was to identify and quantify, through mathematical models, the main factors of production in growing and finishing pig units linked to three Brazilian cooperatives located in Western Region of Paraná State that influence the parameters of daily feed intake and feed conversion ratio. The records of 216 growing and finishi

5. 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

6. Levels of lysine and nutrition plans for pigs of high genetic potential for carcass meat deposition from 21 to 63 days old / Níveis de lisina e planos de nutrição para suínos de alto potencial genético para deposição de carne na carcaça dos 21 aos 63 dias de idade
Foram conduzidos dois experimentos com objetivo de avaliar níveis de lisina e planos de nutrição para suínos com alto potencial genético para deposição de carne na carcaça dos 21 aos 63 dias de idade. No experimento I, foram utilizados 144 leitões, sendo 68 machos castrados e 76 fêmeas, híbridos comerciais, com alto potencial genético para deposi

7. Efeito de altos niveis de zinco suplementar no desempenho e na mortalidade de leitoes.
Avaliou-se a suplementacao com Zn proveniente do oxido de zinco, na dieta de desmame de leitoes. Foram utilizados dois niveis de Zn (0 e 3.000 ppm) de 0 a 21 dias apos o desmame (primeira fase), tres niveis (0,1500 e 3.000 ppm) de 22 a 42 dias apos o desmame (segunda fase) e algumas de suas combinacoes. Foram utilizados 186 leitoes cruzados (D x LW), desmama

8. PRODUÇÃO DE GRÃOS, MATÉRIA SECA E ACÚMULO DE NUTRIENTES EM CULTURAS SUBMETIDAS À ADUBAÇÃO ORGÂNICA E MINERA / PRODUCTION OF GRAIN, DRY MATTER AND NUTRIENT ACCUMULATION IN CROPS SUBMITTED TO ORGANIC AND MINERAL FERTILIZATION
In Brazil, one of the main activities on small farms is the creation of small animals. The waste produced in this activity can be used as an alternative fertilizer because it contains a number of chemicals readily available or after the process of mineralization can be absorbed by plants. However, the imbalanced composition of the organic fertilizers because

9. Efeitos do ácido fítico dietético e da enzima fitase em suínos na fase de terminação e ação do ácido fitico sobre a integridade epitelial das células IPEC- 1
The objective of this study was to evaluate the effect of phytic acid, carried mainly by defatted corn germ meal (DCGM) in the finishing pigs diet and the addition of phytase on the performance parameters, carcass and serum profiles, meat and fresh sausage qualities. Thirty two pigs from a commercial line Pen Ar Lan (16 barrows and 16 gilts) averaging (± SD

10. Níveis de ractopamina nas dietas de suínos machos castrados na fase de terminação / Ractopamine levels in diet for finishing borrows
The swine production in Brazil has become in recente years, a highly dynamic activity, because the consumer is getting increasingly demanding especially with rescpet to the product it consumes. This fact, coupled with the need for the producer to remain in business, have meant that people involved in the chain pig were in constant learning and the search for

12. Aditivos fitogênicos e butirato de sódio como potenciais promotores de crescimento de leitões recém-desmamados / Phytobiotic additives and sodium butyrate as potential growth promoters of weanling pigs
The antimicrobials growth promoters in the animal feed have been related to an increase on animal performance. However, due to the restriction of many countries to the use of antimicrobial as growth promoters, alternatives are being studied. So, the purpose of this work was to evaluate the effect of phytobiotic additives, sodium butyrate and even colistina o
