Provedor de dados: 89
Autores: Duarte,CRA; Murakami,AE; Boso,KMO; Eyng,C; Ospina-Rojas,IC; Matumoto-Pintro,PT.
This study evaluated the performance and the quality and fatty acid profile of eggs from laying hens fed diets containing mixed crude glycerin (MCG; 80% vegetable fat + 20% animal fat). A total of 240 39-week-old Hy-Line W36 laying hens were distributed according to a completely randomized experimental design into six treatments consisting of graded MCG dietary inclusion levels (0, 1.5, 3.0, 4.5, 6.0, and 7.5%), with five replicates of eight birds each. Feed intake linearly decreased (p&lt;0.05) with increasing MCG inclusion levels. The percentages of myristic, palmitic, and α-linolenic acids in the eggs linearly decreased as MCG dietary levels increased (p&lt;0.05), while α-linoleic acid, polyunsaturated fatty acids (PUFA) and ω-6/ω-3 ratio linearly...

Provedor de dados: 89
Autores: Trautenmüller,H; Broch,J; Pires Filho,IC; Silva,IM; Frank,R; Schöne,RA; Carvalho,PLO; Eyng,C; Nunes,RV.
ABSTRACT The objective of this study was to evaluate the energetic values of dry residue of cassava (DRC) and the effects of its inclusion in broiler diets on performance, intestinal morphometry, protein and fat deposition rate, and carcass and cut yields. In experiment I, two metabolism trials were carried out from 11-21 and from 31-41 days of age. The birds were distributed in a completely randomized design and DRC was included at levels of 10, 20, 30 and 40% in the basal diet. In experiment II, 980 male chicks were distributed in a completely randomized design with seven treatments (0; 2; 4; 6; 8; 10; 12% DRC) and seven replicates. DRC levels did not influence (p&gt;0.05) the energetic values. From days 1-7, weight gain (WG) had a linear adjustment, and...

Technical Cashew Nutshell Liquid in Diets of Growing Meat-Type Quails
Provedor de dados: 89
Autores: Sanches,LM; Eyng,C; Garcia,RG; Alves,GP; Sangalli,GG; Nunes,RV.
ABSTRACT The aim of this study was to evaluate the inclusion of technical cashew nutshell liquid (TCNSL) in European quails (Coturnix coturnix coturnix) diets from 1 to 35 days of age on the performance, carcass traits, and development of the digestive organs. 575 quails were distributed in a completely randomized design with five treatments (0%, 0.25%, 0.50%, 0.75%, and 1.00% TCNSL), five replicates, and 23 birds per experimental unit. Live performance was evaluated by weight gain, average feed intake, and feed to conversion ratio. The relative weight of the digestive organs (proventriculus, gizzard, pancreas, liver, small intestine, and large intestine), length of the small and large intestine, and carcass and parts yield (breast, wing, and leg) were...

Dried Cassava Residue in Laying Quail Feeding
Provedor de dados: 89
Autores: Almeida,AZ; Eyng,C; Garcia,RG; Nunes,RV; Sangalli,GG; Nunes,KC.
ABSTRACT This study evaluated the performance, egg quality, relative weight of the gastrointestinal organs, and the intestinal morphometry of laying quails fed diets containing levels of dried cassava residue (DCR). A total of 120 150-day-old Japanese quails were distributed in a completely randomized design with five treatments (0.0; 2.5; 5.0; 7.5; and 10.0% of DCR), four replicates, and six birds per experimental unit. The dietary inclusion of DCR did not affect (p&gt;0.05) performance, internal egg quality, yolk color, and the values of villus height, crypt depth, and villus height/crypt depth ratio for the segments of the small intestine. However, a linear increase (p&lt;0.05) was found for eggshell thickness, relative weight of the gizzard, and small...

Performance and Carcass Yield of Broilers Fed Crude Glycerin at Differing Inclusion Levels
Provedor de dados: 89
Autores: Broch,J; Henz,J; Nunes,R; Eyng,C; Savaris,V.
ABSTRACT This experiment was conducted to evaluate the effect of crude glycerin at differing inclusion levels on performance and carcass characteristics of broilers and litter moisture. 960 broilers of 21-42 days of age were used in a completely randomized design with six crude glycerin inclusion levels (0, 3, 6, 9, 12, 15%), with eight replicates containing 20 broiler chickens per experimental unit. There was a quadratic effect (p&lt;0.05) for weight gain, feed intake and feed:gain ratio from 21 to 42 days of age. Higher levels of crude glycerin in diets increased (40.24%, p&lt;0.05) the litter moisture and reduced (6.04%, p&lt;0.05) the viability of of the birds. There were no effects (p&gt;0.05) on carcass yield, breast, or liver percentages. However,...

Effect of Led Lighting Colors for Laying Japanese Quails
Provedor de dados: 89
Autores: Nunes,KC; Garcia,RG; Nääs,IA; Eyng,C; Caldara,FR; Sgavioli,S; Roriz,BC; Ayala,CM.
ABSTRACT Time of exposure and light intensity rearing house may affect the performance and egg quality of laying quails. This research aimed at evaluating the live performance, egg quality, biometry of the reproductive system, and the gastrointestinal tract of Japanese quails (Coturnix coturnix japonica) exposed to artificial light-emitting diodes (LED) of different colors in comparison with fluorescent lamps. A total of 240 Japanese quails were distributed in completely randomized experimental design with four treatments (fluorescent lamp, and green, red, or blue LED lamps) with six replicates of 10 birds each. Average egg weight and eggshell thickness were different (p&lt;0.05) when LED bulbs were compared with fluorescent lamps. The egg weight of the...
