Effect of Energy and Protein on Performance, Egg Components, Egg Solids, Egg Quality, and Profits in Molted Hy-Line W-36 Hens

Effects of Protein in Diet and Sex Ratio on Egg Production, Egg and Hatching Chick Weight, Fertility, Hatchability and Embryonal Mortality in Pheasants (Phasianus Colchicus)

“…Some researchers reported the general tendency increase egg production and egg weight with the increase of protein levels in the diets (Gunawardana et al, 2008;King'ori et al, 2010;Mohiti-Asli et al, 2012;Shim et al, 2013). Some other researchers reported that egg production and egg weight was not affected by feeding low crude protein (Cho et al, 2004;Khajali et al, 2008).…”

Efeito dos níveis de energia para poedeiras comerciais no período final de produção sobre o desempenho, a conversão alimentar e energética e a qualidade de ovos

“…Para a análise de UH, foram coletados 30 ovos de cada tratamento, cinco repetições de seis ovos. Os ovos foram pesados individualmente e quebrados para medição da altura do albúmen, utilizando-se o aparelho medidor de UH (Ames, modelo S-8400, Massachussets, EUA) (Haugh, 1937 Sloan et al, 1999;Faria et al, 2000;Colvara et al, 2002;Junqueira et al, 2006, Wu et al, 2007e 2008 Sloan et al, 1999;Costa et al, 2004;Junqueira et al, 2006, Wu et al, 2007e 2008Gunawardana et al, 2008. Entretanto, Faria et al (2000 e Colvara et al (2002) encontraram em seus trabalhos ovos mais pesados para as aves alimentadas com rações mais energéticas.…”

“…3). Os resultados encontrados no presente trabalho corroboram todos os resultados apresentados na literatura consultada (Grobas et al, 1999;Costa et al, 2004;Junqueira et al, 2006;Wu et al, 2007;Gunawardana et al, 2008;Valkonen et al, 2008 Gunawardana et al (2008).…”

Effect of Varied Levels of Dietary Crude Protein and Metabolizable Energy on Production Performance in Giriraja Parent Birds

“…The diets with 2800 kcal/kg ME, 15% CP (T 4 ) and 2700 kcal/kg ME, 17% CP (T 3 ) had better production with 65.35 and 65.33 per cent on a pooled basis. Gunawardana et al (2008). Low energy (2225 kcal ME/kg) and low protein (16% CP) in layer ration was found good for IWN strain of White Leghorn, with no adverse effect on growth and egg production (Sahasnani et al, 2013).…”
