Performance and characteristics of carcass and non-carcass components of lambs fed peach-palm by-product

Abstract

The objective of this study was to evaluate the effects of supplying the by-product of peach-palm (Bactris gasipaes) on performance and characteristics of carcass and non-carcass components of feedlot lambs. Twenty Santa Ines lambs of 150 days average age and 22.4 ± 3.4 kg body weight were confined in individual pens. A completely randomized design was utilized with four experimental diets composed of: fresh peach-palm by-product enriched with urea, fresh peach-palm by-product + concentrate, silage of peach-palm by-product + concentrate, and silage of peach-palm by-product enriched with 15 % corn meal + concentrate. Intake was evaluated daily, and at the end of 42 days of experiments, lambs were slaughtered and the characteristics of carcass and non-carcass parts were evaluated. Performance and carcass characteristics showed differences between the animals' intake of total mixed rations (TMR) and only the diet with roughage. For the lambs that intaked TMR, the form of utilization of roughage (fresh or as silage) affected animal performance but did not change the carcass characteristics. Dry matter intake and feed conversion were influenced by the form of utilization of the silage (with and without additive). Providing fresh by-product plus concentrate improves lamb performance but does not interfere in the carcass characteristics, compared with the use of by-product in the form of silage.

Gestão ambiental e caracterização de resíduos sólidos de agroindústrias de palmito pupunha do estado do Paraná

“…. Gestão ambiental e caracterização de resíduos sólidos de agroindústrias de palmito pupunha do estado do Paraná Estima-se que, no Sul da Bahia, a produção de palmito renda cerca de 40 t.dia -1 de subproduto (Cabral et al, 2013). Já em Sinop (MT), um estudo constatou que os resíduos orgânicos gerados durante o processamento do palmito exalam mau cheiro, motivo pelo qual a sua destinação final deve ser célere.…”

“…Gestão ambiental e caracterização de resíduos sólidos de agroindústrias de palmito pupunha do estado do Paraná Analisando os dados para fins de cálculo da quantidade de subprodutos gerados nas quatro indústrias de processamento de palmito, constatou-se a produção de 21.956,34 kg dia -1 de resíduos (5,11 kg de resíduo por kg de palmito). Estudos realizados em agroindústrias de conservas de palmito no Brasil revelaram a geração de 2.000 kg dia -1 em unidades do Mato Grosso (Paixão et al, 2016) e do Pará (Souza et al, 2009), 40.000 kg dia -1 no sul da Bahia (Cabral et al, 2013) e 340.000 kg dia -1 em 50 instalações de Santa Catarina (Schmitz et al, 2018).…”
