Resumo: | The objective of this experiment was to evaluate the effects of metabolizable energy (ME) levels in diets with high digestible lysine concentration on performance, carcass traits, and meat quality of barrows from 95 to 158 days of age. Eighty commercial hybrid barrows (50 ± 1.82 kg) selected for lean meat deposition, were assigned to four dietary treatments (3,150, 3,235, 3,320, and 3,400 kcal EM kg-1) in a randomized design with 10 replicate pens per treatment and two pigs per pen. From 95 to 116 days of age, we observed no effects of ME on final body weight (FBW), average daily gain (ADG), metabolizable energy intake (MEI), and feed conversion (F: G). Average daily feed intake (ADFI) decreased linearly with increasing ME levels (? = 5.79961 - 0.00096790X - r2 = 0.89). From 95 to 137 days of age, no effects of ME were observed on final body weight (FBW), average daily gain (ADG), metabolizable energy intake (MEI), and feed conversion (F: G). Average daily feed intake (ADFI) decreased linearly with increasing ME (?= 6.1176 - 0.001X - r2= 0.97). From 95 to 158 days, of age no effects of ME were observed on FBW and ADG. Dietary ME influenced the ADFI and F: G, which decreased linearly with increasing ME concentrations (?= 8.12951 - 0.00149X - r2= 0.99; ?= 6.0914 - 0.001X - r² = 0.75, respectively). There was a linear increase in loin eye area (LEA) with increasing ME (? = - 29.851 + 0.0207 X - r² = 0.87). Backfat thickness, pH, and temperature, measured at different times after slaughter (0 min, 45 min, 3 h, and 24 h), were not affected by dietary ME. The level of ME also did not affect the meat quality parameters Color L*, Color a*, Color b*, Warner-Bratzler shear force, thaw water losses, cooking water losses, sum of water losses, intramuscular fat content, and TBARS. Diets with 3,400 kcal kg-1 ME, corresponding to 2.75, 2.57, and 2.31 g digestible lysine/Mcal of ME for pigs from 95 to 116, 116 to 137, and 95 to 158 days of age, respectively, resulted in best performance and carcass traits, without negative effects on meat quality. |

Foram utilizados 80 suínos (Agroceres PIC), machos castrados, com peso inicial de 50 ± 1,82 kg. Os animais foram distribuídos em delineamento inteiramente casualizado, com quatro tratamentos (3150 kcal EM kg-1, 3235 kcal EM kg-1, 3320 kcal EM kg-1, 3400 kcal EM kg-1), dez repetições e dois animais por unidade experimental, representada pela baia. No período de 95 a 116 dias de idade, não foram observados efeitos dos níveis de EM sobre os parâmetros de desempenho: peso médio final (PMF), ganho de peso médio diário (GPD), consumo de energia metabolizável (CEM) e conversão alimentar (CA). O consumo de ração médio diário (CDR) reduziu de forma linear com o aumento dos níveis de EM da ração (?= 5,79961 - 0,00096790 X - r2= 0,89). No período de 95 a 137 dias de idade, não foram observados efeitos dos níveis de EM sobre os parâmetros de desempenho: peso médio final (PMF), ganho de peso médio diário (GPD), consumo de energia metabolizável (CEM) e conversão alimentar (CA). O consumo de ração médio diário (CDR) reduziu de forma linear com o aumento dos níveis de EM da ração (?= 6,1176 - 0,001X - r2= 0,97). No período de 95 a 158 dias de idade, não foram observados efeitos dos níveis de EM sobre o PMF e o GPD dos suínos. O CDR e a CA dos animais reduziram de forma linear com o aumento dos níveis de EM da ração (?= 8,12951 - 0,00149X - r2= 0,99 e ?= 6,0914 - 0,001X - r² = 0,75; respectivamente). Verificou-se aumento linear da área de olho de lombo com o aumento do nível de EM das rações, (? = -29851 + 0,0207X - r² = 0.87). A espessura de toucinho, o pH e a temperatura medida em diferentes tempos após o abate (0 min, 45 min, 3 horas e 24 horas) não foram influenciados pelos níveis de EM da ração. Não foi observado efeito dos níveis de EM sobre os parâmetros de qualidade carne: Cor L*, Cor a*, Cor b*, força de cisalhamento Warner-Bratzler, perda de água no descongelamento, perda de água na cocção, perda de água total, gordura intramuscular e TBARS. Rações com 3400 kcal de EM kg-1, correspondendo às relações de 2,75; 2,57 e 2,31 g de lisina digestível/Mcal de EM, dos 95 aos 116, dos 116 aos 137 e dos 95 aos 158 dias de idade, respectivamente, resultam em melhor desempenho e características de carcaça, sem efeitos negativos na qualidade da carne de suínos machos castrados.UEL2019-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3271410.5433/1679-0359.2019v40n1p365Semina: Ciências Agrárias; Vol. 40 No. 1 (2019); 365-378Semina: Ciências Agrárias; v. 40 n. 1 (2019); 365-3781679-03591676-546Xreponame:Semina.

The objective of this experiment was to evaluate the effects of metabolizable energy (ME) levels in diets with high digestible lysine concentration on performance, carcass traits, and meat quality of barrows from 95 to 158 days of age. Eighty commercial hybrid barrows (50 ± 1.82 kg) selected for lean meat deposition, were assigned to four dietary treatments (3,150, 3,235, 3,320, and 3,400 kcal EM kg-1) in a randomized design with 10 replicate pens per treatment and two pigs per pen. From 95 to 116 days of age, we observed no effects of ME on final body weight (FBW), average daily gain (ADG), metabolizable energy intake (MEI), and feed conversion (F: G). Average daily feed intake (ADFI) decreased linearly with increasing ME levels (? = 5.79961 - 0.00096790X - r2 = 0.89). From 95 to 137 days of age, no effects of ME were observed on final body weight (FBW), average daily gain (ADG), metabolizable energy intake (MEI), and feed conversion (F: G). Average daily feed intake (ADFI) decreased linearly with increasing ME (?= 6.1176 - 0.001X - r2= 0.97). From 95 to 158 days, of age no effects of ME were observed on FBW and ADG. Dietary ME influenced the ADFI and F: G, which decreased linearly with increasing ME concentrations (?= 8.12951 - 0.00149X - r2= 0.99; ?= 6.0914 - 0.001X - r² = 0.75, respectively). There was a linear increase in loin eye area (LEA) with increasing ME (? = - 29.851 + 0.0207 X - r² = 0.87). Backfat thickness, pH, and temperature, measured at different times after slaughter (0 min, 45 min, 3 h, and 24 h), were not affected by dietary ME. The level of ME also did not affect the meat quality parameters Color L*, Color a*, Color b*, Warner-Bratzler shear force, thaw water losses, cooking water losses, sum of water losses, intramuscular fat content, and TBARS. Diets with 3,400 kcal kg-1 ME, corresponding to 2.75, 2.57, and 2.31 g digestible lysine/Mcal of ME for pigs from 95 to 116, 116 to 137, and 95 to 158 days of age, respectively, resulted in best performance and carcass traits, without negative effects on meat quality. |
