Use of macaúba cake replacing corn on carcass characteristics and body measurements of Santa Inês lambs

Abstract

-This experiment evaluated the effect of adding macaúba (Acrocomia aculeata) cake replacing corn on body measurements and carcass characteristics of Santa Inês lambs. Twenty four 5-month-old uncastrated male lambs were tested using a randomized blocks design. Lambs were distributed into four experimental groups, receiving diets with 0, 100, 200 and 300 g/kg of macaúba cake. After 60 days in feedlot, measurements of body length, thoracic perimeter, height at the anterior and rump height were taken. The lambs were slaughtered, skinned and eviscerated. Carcass were weighed hot and chilled at 2 o C during 24 h. Cooling losses, hot carcass weight, cold carcass weight, hot carcass yield, cold carcass yield, half carcass weight, fat thickness, final weight, slaughter weight, empty body weight, thorax depth, croup width, perimeter of the croup, carcass length, internal carcass length, hindlimb length, hindlimb width and hindlimb conformation score were evaluated. Only hindlimb width was inversely correlated to adding macaúba cake in the diet. Macaúba cake can be included in diets for lamb in feedlot up to 300 g/kg without affecting body measurements in vivo or carcass characteristics.

Feeding Systems and the Physicochemical and Sensory Quality of Lamb Meat: Can Feeding Systems Affect Lamb Meat Quality?

“…The suckling lamb meat presented lower WHC and higher TWL (Table 4). The higher fat thickness in supplemented lamb carcasses could have protected them against water loss on cooling, as stated by Sañudo et al (1997) and Fonseca et al (2012). However, those differences were not high enough to affect the CWL and SF (instrumental) or sensory ISSN 2166-0379 2019 tenderness (Table 7).…”

Genetic diversity via REML-BLUP of ex situ conserved macauba [Acrocomia aculeata (Jacq.) Lodd. ex Mart.] ecotypes

“…In terms of energy, the endocarp is suited for charcoal production (Silva et al 1986;Evaristo et al 2016), and the waste biomass is suited for bio-oil production (Cardoso et al 2016). Vegetal oil extraction residues (pulp and kernel cake) have a potential for animal feed (Rufino et al 2011;Azevedo et al 2012;Fonseca et al 2012). In addition to the evidenced potential of this species in a future scenario of climate change, i.e., an increase in terrestrial temperature, an increase in water deficiency and forecasts of changes in the current agricultural configuration in Brazil for the next decades (Pinto et al 2008), native species from arid regions, or those occurring in dry seasons, such as macauba, may become viable alternatives in areas with a greater climatic risk for the production of food and renewable energy.…”

Macauba palm cake as additive in elephant grass silage

“…ex Mart.) cake presents some intrinsic characteristics such as high contents of dry matter (from 87 to 89%) and ethereal extract (from 8 to 20 %) and high concentration of non-fibrous carbohydrates (Fonseca et al, 2012;Santos et al, 2015;Silva et al, 2015). These characteristics highlight its potential as an ingredient in ruminant diets or as a moisture sequestering additive in tropical grass silages.…”
