1. Determination of nutrient and energy values of cottonseed meal supplemented or not with phytase and protease for broiler chicks
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

2. Energy efficiency of pasta waste and its effect on performance, carcass, and economic viability of broilers
ABSTRACT The objective of this study was to determine the energy value of pasta waste through a metabolism trial and determine the best level of its inclusion in broiler diets. In the metabolism trial, sixty 14-day-old birds were assigned to two treatments (control diet and a diet in which 30% was replaced by the byproduct) with six replicates and five birds

3. Evaluation of growth performance and gastro-intestinal parameters on the response of weaned piglets to dietary organic acids
ABSTRACT Two experiments (E) were carried out to evaluate the effects of fumaric acid and an acidifier blend [composed by calcium formate, calcium lactate and medium-chain fatty acids (capric and caprylic)] in piglet diets containing colistin (40 ppm) or halquinol (120 ppm) on performance, diarrhea incidence (E1), organs relative weight, pH values, intestina

4. Substitution of blood plasma with soy protein concentrate in piglet diet
ABSTRACT In this study, we evaluated the effects of substitution of partial and total spray-dried blood plasma (BP) with soy protein concentrate (SPC) in the diet of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Fifty-four castrated male piglets, weaned at an average age of 21 days and an initial average weight

5. Evaluation of Dietary Glycerin Inclusion During Different Broiler Rearing Phases
ABSTRACT The objective of this study was to evaluate the effect of the dietary addition of different levels of glycerin on the performance, litter moisture, pododermatitis incidence, and carcass and parts yield of broilers. In total, 1,610 broilers were reared in 35 pens with 46 birds each. A completely randomized experimental design, with five treatments wi

6. Performance, Intestinal Morphology and Microbiology of Broiler Chickens Fed Egg Powder in the Starter Diet
ABSTRACT The effect of egg powder inclusion in the pre-starter diet (1-7 days of age) on the performance, and intestinal morphology and microbiology of male broiler chickens was evaluated in a completely randomized design. Starter diets with equal metabolizable energy and crude protein levels were formulated to contain 0, 20, 40, or 60 g egg powder/kg diet.

7. Addition of Amylase from Aspergillus Awamori to the Diet of Broiler Chickens
ABSTRACT Two experiments were performed to evaluate the hematological and blood biochemistry parameters, biometry of digestive organs, enzyme activities, protein content and absolute weight of the pancreas of broilers fed pre-starter and pre-starter diets supplemented or not with amylase from Aspergillus awamori. In total, 120 male Cobb chicks were housed in

8. DIGESTIBLE VALINE REQUIREMENTS IN LOW-PROTEIN DIETS FOR BROILERS CHICKS
ABSTRACT Three experiments were carried out to evaluate the levels of digestible valine in diets with reduced crude protein on the performance, carcass yield and muscle fiber diameter of male broilers during the pre-starter (1 to 8 d of age), starter (9 to 21 d of age) and grower phases (21 to 42 d of age). A total of 1,080 chickens in the pre-starter phase,

9. PERFORMANCE AND NUTRIENT METABOLIZABILITY IN BROILERS FED DIETS CONTAINING CORN CONTAMINATED WITH FUMONISIN B1 AND ESTERIFIED GLUCOMANNAN
ABSTRACTAn experiment was conducted to evaluate the performance and nutrient metabolizability of broilers fed diets containing fumonisin B1 (FB1) and an esterified glucomannan (EGM). In total, 420 male broilers were distributed according to a 3 x 2 + 1 factorial arrangement, corresponding to three FB1 exposure times (seven, 21, or 35 days), two dietary gluco

10. The use of whole grain sorghum in broiler feeds
In broiler feed manufacturing, grinding may significantly increase costs due to electric energy use. This study evaluated the performance and the morphometrics of the gastrointestinal tract of broilers. According to a completely randomized experimental design, 2,400 birds (1,200 males and 1,200 females) were submitted to five treatments of eight replicates e

11. Effect of plasma and/or yeast extract on performance and intestinal morphology of piglets from 7 to 63 days of age
The objective of this study was to evaluate the effect of diets supplemented with plasma and/or yeast extract on performance (daily weight gain [DWG], daily feed intake [DFI] and feed conversion [FC]) and intestinal morphology of piglets from 7 to 63 days of age. A total of 288 piglets aged 7 days and weighing 2.57±0.05 kg were studied. A randomized block d

12. Diet formulation techniques and lysine requirements of 1- to 22-day-old broilers
Two experiments were carried out to compare two techniques (amino acid supplementation and dilution) for formulating experimental diets for pre-starter (1 to 8 days) and starter (8 to 22 days) broiler chicks and to estimate digestible lysine requirements using the dose-response method. In each experiment, 1,200 male Cobb 500 chickens were randomly distribute
