Productive performance of broiler chickens fed tomato waste

Abstract

-Aiming to evaluate the effect of tomato waste inclusion on productive performance and characteristics of carcass and main broiler chicken cuts, an experiment was carried out using 300 male Cobb chicks, distributed in a complete randomized design, with five rations and five replicates. Diets consisted of control ration based on corn and soybean meal and four rations with 5, 10, 15 and 20% of tomato waste. Feed intake, weight gain and feed conversion and, at the end of experiment, slaughter weight, gutted carcass without feet and head, breast, drumstick, thigh, wing, back, edible guts and belly fat were evaluated every week, as well as it was the yield. Tomato waste increased feed intake in the periods from 1 to 7, 8 to 14 and 29 to 36 days of age and worsened gain weight and feed conversion of broiler chickens up to 29 days of age.Regarding carcass weight (g) and weight of the noble parts, breast, drumstick and thighs decreased linearly in function of the use of tomato waste in poultry on pre-initial and initial phase, that is, up to 28 days old, but yield (%) was not affected except for yield of heart and liver. Use of tomato waste in ration of broiler chickens during the period from 1 to 28 days may decrease weight gain and worsen food conversion. Tomato waste may be used as ration ingredient in ration of broiler chicken in the breeding period from 29 to 42 days of age up to the level of 20% without harming weight gain and feed conversion of poultry.

The effect of lycopene and vitamin E on the growth performance, quality and oxidative stability of chicken leg meat

“…In contrast, an increased feed consumption as a result of lycopene supplementation was observed in Japanese quails reared at a high ambient temperature (Sahin et al, 2006a). In broiler chickens, Lira et al (2010) reported that dietary supplementation of tomato waste that was high in lycopene increased feed intake in the periods from 1 to 7, 8 to 14 and 29 to 36 days of age and worsened weight gain and feed conversion up to 29 days of age. The authors also reported that vitamin E addition significantly reduced the live weight of chickens at the end of fattening.…”

Resíduo de acerola em dietas para codornas

“…Resultados semelhantes foram obtidos por Ramos et al (2006), que recomendaram a inclusão de até 15% de polpa de caju desidratada para frangos de corte. Da mesma forma, Lira et al (2010) Torna-se relevante considerar que, em razão de o resíduo de acerola ser um ingrediente com baixo conteúdo energético (754kcal de EM/kg), fez-se necessária a adição de óleo vegetal para suprir as exigências energéticas das codornas, uma vez que, com a elevação de níveis de inclusão do coproduto, ocorre a redução da fonte energética (milho)das dietas experimentais.Com o intuito de manter o balanço energético, Ramos et al (2006) e Zanetti et al (2014) Constatou-se efeito linear dos níveis do resíduo da acerola sobre o peso relativo da moela, em que severificou um aumento de 0,04g/ave a cada 1% de inclusão do resíduo da acerola, conforme a equação:Ŷ = 3,9628 + 0,0360X (R²= 0,95).O aumento do tamanho da moela ocorreu pelo aumento do teor de fibras nas dietas de maior nível do resíduo da acerola, que pode ser justificado, possivelmente, pela maior granulometria e quantidade de fibra das rações, pois o resíduo de acerola é constituído por casca, polpa, e sementes, o que pode ter provocado maiores contrações dos músculos da moela, promovendo, assim, maior massa muscular (González et al, 2007). Resultados semelhantes foram obtidos por Pinto et al 2014, que observaram aumento da moela entre os níveis testados com resíduo de acerola para frangos de corte.…”

“…Resultados semelhantes foram obtidos por Pinto et al 2014, que observaram aumento da moela entre os níveis testados com resíduo de acerola para frangos de corte. Lira et al (2010) constataram aumento no peso relativo da moela de frangos de corte à medida que se elevou o nível de subproduto da goiaba para 10% de inclusão.…”

Effect of tomato (Solanum lycopersicum L.) protein on carcass and meat quality of kampong chicken

“…According to Jouzi et al (2015), dried tomato pulp may be used as ingredient in quails ration up to level of 4-6 % without harming weight gain and feed conversion of birds. Tomato waste has used as feedstuff in broiler diet up to 20% level without harming weight gain and feed conversion of poultry (Lira et al, 2010).…”
