This study was conducted to determine the digestible lysine requirements of Nile tilapia fingerlings. Fish (n = 300; average initial weight = 1.44 g) were distributed 15 300-L aquariums, in a completely randomized design with five treatments and three replicates, and fed extruded diets containing 11.3, 13.7, 16.1, 18.4 or 20.8 g/kg of digestible lysine. The arginine:lysine ratio was maintained at 1.3:1. All fish were fed diets containing 281 g/kg of digestible protein and 3,372 kcal digestible energy/kg, hand-fed until apparent satiation. There was no effect of the dietary lysine levels on survival rate, or protein and ash body rates. With increasing levels of lysine in the diet, a quadratic effect on weight gain, feed conversion, protein efficiency ratio,...

The objective of this study was to evaluate the effects of increasing dietary digestible tryptophan levels on performance and carcass traits of growing pigs. Fifty crossbred castrated male pigs, with average initial and final body weight of 29.0 ± 1.20 kg and 60.4 ± 1.95 kg were allotted in a completely randomized block design, with five treatments (0.125, 0.133, 0.141, 0.149, and 0.157% of digestible tryptophan, corresponding to digestible tryptophan:lysine relations of 15.0, 16.0, 17.0, 18.0, and 19.0%, respectively) and five replicates, with two pigs per experimental unit, which was represented by the pen. Experimental diets and water were supplied ad libitum throughout the experimental period. Averages of minimum and maximum temperatures inside the...

Digestible tryptophan levels in diets for pigs weighing 15 to 30 kg
Provedor de dados: 96
Autores: Apolônio,Lourdes Romão; Donzele,Juarez Lopes; Oliveira,Rita Flávia Miranda de; Saraiva,Alysson; Silva,Francisco Carlos de Oliveira; Ferreira,Aloízio Soares; Lima,Anderson Lazarini; Kill,João Luís.
In order to evaluate the effects of increasing dietary tryptophan levels on performance and carcass characteristics of growing pigs, a total of 60 crossbred castrated male pigs, with average initial and final body weights of 15.50 ± 1.15 and 30.60 ± 1.35 kg were used. Pigs were allotted in a completely randomized block design, with five dietary treatments (0.149, 0.158, 0.168, 0.177, and 0.187% digestible tryptophan, corresponding to digestible tryptophan:lysine relations of 16.0, 17.0, 18.0, 19.0, and 20.0%), six replicates, and two animals per experimental unit, which was represented by the pen. Experimental diets and water were supplied ad libitum throughout the experimental period. The average maximum and minimum temperatures inside the rooms were of...

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,...

Potential Protein Deposition in the European Wild Boar (Sus scrofa L.)
Provedor de dados: 117
Autores: Quijada,Roberto P; Hodgkinson,Suzanne M.
The growth rate of farmed European wild boars (Sus scrofa L.) is perceived to be very slow. However, there is no available information on the genetic potential of these animals in terms of potential lean tissue growth.The aim of the study was to determine the maximum capacity for protein deposition (operational PDmax) in wild boars under controlled environmental conditions. Four diets were formulated containing different levels of digestible energy (DE): 2.2, 2.4, 2.6, and 2.8 Mcal DE kg-1. All of the diets contained at least 5 g lysine per Mcal DE. Twenty purebred wild boars from a commercial farm of the same age (± 4 d) and with an initial liveweight of 27 ± 0.50 kg (mean ± standard error of the mean) were used in the study. At the beginning of the study...
