CASHEW NUT MEAL IN THE FEEDING OF BROWN LAYING HENS Ciência e Agrotecnologia
Cruz,Carlos Eduardo Braga; Freitas,Ednardo Rodrigues; Xavier,Regina Patrícia de Souza; Fernandes,Danilo Rodrigues; Nascimento,Germano Augusto Gerônimo; Watanabe,Pedro Henrique.
The use of alternative foods to replace conventional foods is becoming a source of research for many researchers. The cashew nut meal (CNM) has high energy and protein value, may be a partial substitute for corn and soybean meal for poultry feed. In this context, this research was conducted to evaluate the effect of inclusion of CNM on the utilization of nutrients in the ration for laying hens, as well as the performance and characteristics of the eggs. The study used 180 Dekalb Brown laying hens 27 weeks of age, distributed in a completely randomized design with six treatments and five replicates of six birds. Treatments consisted of a control diet without CNM and others with the inclusion of this food at levels of 5, 10, 15, 20 and 25%. Upon regression...

Comparative evaluation of dietary oregano, anise and olive leaves in laying Japanese quails Rev. Bras. Ciênc. Avic.
Christaki,EV; Bonos,EM; Florou-Paneri,PC.
Aim of the present study was the comparative evaluation of the effect of ground oregano, anise and olive leaves as feed additives on performance and some egg quality characteristics of laying Japanese quails. A total of 189 Coturnix japonica quails (126 females and 63 males), 149 days old, were randomly allocated into seven equal groups with three subgroups of 9 birds each (6 females and 3 males). A commercial laying diet was fed to the control group. The remaining six groups were fed the same diet supplemented with oregano at 10 g/kg or 20 g/kg, anise at 10 g/kg or 20 g/kg and olive leaves at 10 g/kg or at 20 g/kg. The birds were offered feed and water ad libitum for a period of 29 days, while being kept under commercial conditions. During the experiment,...

Effect of using organic microminerals on performance and external quality of eggs of commercial laying hens at the end of laying R. Bras. Zootec.
Maciel,Mônica Patrícia; Saraiva,Edilson Paes; Aguiar,Édina de Fátima; Ribeiro,Pedro Assunção Pimenta; Passos,Débora Pereira; Silva,Jussara Barros.
The objective of the present study was to evaluate the effect of using microminerals in organic form on the performance and quality of eggs from commercial laying hens at the end of laying. Four hundred and eighty Hisex strain hens, 72 to 80 weeks of age, were used. A randomized complete design was used, with six replications and 16 birds for each experimental unit. Five diets were evaluated: basal feed supplemented with all microminerals in inorganic form (control); basal feed supplemented with 50% microminerals zinc (Zn) + manganese (Mn) + copper (Cu) in organic form and 50% in inorganic form; basal feed supplemented with 50% zinc in organic form and 50% in inorganic form; basal feed supplemented with 50% manganese in organic form and 50% in inorganic...

Parboiled rice whole bran in laying diets for Japanese quails PAB
Quevedo Filho,Ivan Bezerra; Freitas,Ednardo Rodrigues; Filgueira,Thales Marcel Bezerra; Nascimento,Germano Augusto Jerônimo do; Braz,Nádia de Melo; Fernandes,Danilo Rodrigues; Watanabe,Pedro Henrique.
The objective of this work was to evaluate the effects of parboiled rice whole bran (PRWB) inclusion in laying diets for Japanese quails, on their performance, egg quality, and economic viability. A total of 448 17-week-old quails were weighed and distributed in a completely randomized design with seven treatments and eight replicates of eight birds each. A control diet (no PRWB) and six diets, containing 5, 10, 15, 20, 25, and 30% of PRWB, were tested. The increasing levels of PRWB did not affected nutrient digestibility coefficient, dietary energy use, feed intake, egg production, egg weight, egg mass, and the economic viability indices. However, there was a linear decrease in egg shell percentage, specific weight, and yolk color. The inclusion of up to...

Physical characteristics of the eggs of red-legged partridge (Alectoris rufa) reared in captivity Arq. Bras. Med. Vet. Zootec.
Ribeiro,S.; Pereira,A.F.; Capela e Silva,F.; Ferraz de Oliveira,M.I..
O objetivo do presente estudo foi avaliar os efeitos da idade das fêmeas (um, dois e três anos) e do mês de postura (março, abril e maio) sobre as características físicas dos ovos da perdiz vermelha (Alectoris rufa) criada em cativeiro. O peso (W), o comprimento máximo (L) e a largura máxima (B) de 2878 ovos foram determinados diretamente, enquanto o índice de forma (B/L), o volume (V) e a superfície (S) foram calculados com base nos parâmetros determinados diretamente. A análise mostrou diferenças significativas (P<0,01) no peso dos ovos entre as diferentes idades e entre meses de postura, com menor peso nas fêmeas mais jovens. Observaram-se diferenças significativas (P<0,01) no comprimento do ovo entre as classes de idade, mas não entre os meses de...
