ABSTRACT The objective of this study was to evaluate the effect of including whole corn germ (WCG) on the performance; diet metabolizability; yields of carcass, cuts, and offal; and quality of meat of broilers. A total of 648 chicks were assigned to six treatments in a completely randomized design with six replicates, with 18 birds in each. Treatments consisted of a corn- and soybean meal-based control diet (0 g kg−1 WCG) and five test diets including WCG at the levels of 40, 80, 120, 160, and 200 g kg−1. Birds and diets were weighed at each seven days to determine feed intake (FI), body weight gain (BWG), and feed conversion ratio (FCR). The partial collection methodology was employed to determine the apparent metabolizable energy (AME),...

ABSTRACT The objective of this study was to evaluate levels of inclusion of an enzyme complex (EC) in corn- and soybean meal-based diets for laying hens on the digestibility of nutrients and energy. A metabolism trial was conducted using 75 Dekalb Brown laying hens at 26 weeks of age, which were distributed into five treatments with five replicates in a completely randomized design. The ingredients used in the diets received an additional (enriched) 3% methionine, lysine, cysteine, threonine, tryptophan, and metabolizable energy and 33.3% phosphorus. Treatments consisted of diets including 0, 150, 200, 250, or 300 mg.kg‒1 EC. We determined apparent metabolizable energy (AME); nitrogen-corrected AME (AMEn); apparent metabolizability coefficients of dry...

Sugarcane yeast inclusion for broilers at post-hatch
Provedor de dados: 96
Autores: Lopes,Cláudia da Costa; Rabello,Carlos Bôa-Viagem; Silva,Jaqueline de Cássia Ramos da; Arruda,Emmanuele Maria Florêncio de; Ludke,Maria do Carmo Mohaupt Marques; Dutra Junior,Wilson Moreira.
ABSTRACT A total of 450 one-day-old male broiler chicks were used to evaluate the effect of the sugarcane yeast on performance, body composition, and development of the intestinal mucosa. The experiment was carried out in a completely randomized design with five treatments and six replicates of 15 birds. Sugarcane yeast was included in the experimental diets at the levels of 0, 12.5, 25.0, 37.5, and 50.0 g kg−1. Body weight, weight gain, feed intake, and feed conversion were determined. At the end of the experiment, four broiler chicks were slaughtered per experimental unit: two were used for evaluation of moisture content, crude protein, fat, and body ash and the other two were used in the collection of small-intestine segments for evaluation of villus...

Determination of nutrient and energy values of cottonseed meal supplemented or not with phytase and protease for broiler chicks
Provedor de dados: 96

ABSTRACT The objective of this study was to determine the nutritional and energy compositions of cottonseed meal (CM), with or without enzyme supplementation, for broilers at different ages. A total of 672 male Cobb 500 chickens were distributed into four metabolism and ileal-digestibility trials. The experimental design was completely randomized, with four treatments and six replicates. The following treatments were tested: a corn- and soybean meal-based control diet without enzymes; control diet with enzyme addition; control diet with 25% replaced by CM; and control diet with enzyme addition and 25% replaced by CM. The following variables were investigated: apparent metabolizable energy (AME); nitrogen-corrected AME (AMEn); apparent metabolizability...
