Effect of crumbled diet on growth performance, market day age and meat quality of growing-finishing pigs

Abstract

This study was conducted to determine the effect of crumbled diet on growth performance, market day age, and meat quality of growing-finishing pigs. A total of 120 crossbred pigs [(Landrace × Yorkshire) × Duroc] with an average initial body weight (BW) of 25.89 ± 1.93 kg at 68 days of age were randomly allotted to 2 experimental diets based on initial BW (15 replicate pens per treatment, 4 pigs per pen; 2 barrows and 2 gilts). The trial lasted for 120 days. Dietary treatments included: (1) T1 (mash diet); (2) T2 (crumble diet). During the overall study period pigs fed the T2 (crumble diet) had significantly greater (P < .05) average daily gain (ADG) and gain to feed ratio (G:F). Moreover, the number of pigs reaching market age at day 177 was higher in pigs fed crumble diet than mash diet. No significant differences were observed in back-fat thickness, meat colour, sensory evaluation, cooking loss, drip loss, water holding capacity, and longgissimus muscle area (LMA) between T1 and T2 groups. Our results revealed that the growth performance was significantly enhanced in pigs fed with the crumble diet. The crumble diet reduced market day age and meat quality of growing-finishing pigs.ARTICLE HISTORY

Efecto de alimentación húmeda de cerdos en finalización sobre el comportamiento productivo, composición de la canal y calidad de la carne

“…La CRA y el color son atributos importantes que determinan el atractivo visual y la terneza de la carne (32,33) . Los valores observados en este experimento, fueron similares entre tratamientos, y concuerdan con los reportados previamente (34,35) en cerdos de finalización. En el presente trabajo, la carne de cerdos que recibieron alimento húmedo tuvo valores de dureza menores a la de cerdos que recibieron alimento seco, lo cual es indicativo de mayor terneza (36) , que es una de las características más importantes de la calidad de la carne (32,37) .…”

“…En el presente estudio, no se encontraron diferencias entre tratamientos en las variables cromáticas L*, a*, b*, C y H, que determinan el color. Comparado con resultados de investigaciones previas (34) , los valores de luminosidad (L*) en el presente trabajo para la carne de cerdos alimentados con AH y AS (53.6 y 54.0, respectivamente; Cuadro 4) fueron indicativos de carne "normal" (39) . Valores de L* de 58 son indicativos de carne PSE (pálido, suave, exudativo), mientras que valores inferiores a 52 indican la condición de ASD (oscuro, firme, seco) (39,40,41) .…”

Evaluating the effect of finely ground, dry-rolled, and crumbled corn grain on performance, feeding behavior, and starch digestion in Holstein dairy heifers

“…Choi et al (1986) reported that chickens fed the crumbled starter diet had greater intake and Reece et al (1984) observed that pigs fed a high-energy crumble and high-protein profile had the best feed conversion efficiency. Also, Nguyen et al (2017) reported a greater ADG and feed efficiency (FE) in pigs fed a crumble diet rather than mash diet for identical feed intake. However, no research has investigated the effect of crumbled corn on BW gain and metabolic response in dairy heifers.…”

A systematic-review on the role of exogenous enzymes on the productive performance at weaning, growing and finishing in pigs

“…Most studies on animal diets seek strategies to improve feed efficiency, which are of particular interest to increase productive efficacy and reduce environmental impacts ( Aarnink & Verstegen, 2007 ; Clark & Tilman, 2017 ). In this sense, exogenous enzymes improve feed efficiency and reduce feeding costs in the animal production industry ( Adeola & Cowieson, 2011 ; Upadhaya, Park, Lee & Kim, 2016a ), as pig feed accounts for 55–75% of total production costs ( Nguyen, 2017 ).…”
