EVALUATION OF BABASSU MESOCARP MEAL IN FEED FOR BROILER CHICKENS / Avaliação do mesocarpo de Babaçu (Orbignya ssp) na alimentação de frangos de corte.

Abstract

SUMMARYThis study evaluates nutritional value and use of babassu mesocarp supplementation in the feeding of broilers. Initially, the chemical composition was determined in order to characterize the ingredient. Then two tests were conducted: the first, to determine the energy values and the second, the optimal supplementation level in the diet. The metabolism trial was conducted using 20 Leghorn cockerels divided into two treatments with five replicates of two birds each. The experiment lasted ten days, five adaptation days and five days for stool collection. Subsequently, 500 one-day-old broiler chicks were used in the growth trial. The design was completely randomized, with four treatments and five replications. Treatments consisted of four levels of babassu mesocarp supplementation: 0, 3, 6 and 9%. The growth trial lasted 21 days and the responses to feed intake, weight gain and feed conversion were evaluated. Based on natural matter, the babassu mesocarp has 87.5%, 3.29%, 1.1%, 2.7%, 75.1% and 3,618 kcal/kg for the variables dry matter, crude protein, ash, crude fiber, starch and gross energy, respectively. The corrected apparent metabolizable energy determined was 2,671 kcal/kg, based on the natural matter. The babassu mesocarp due to its low crude protein content and high starch level can be classified as an energy ingredient. The babassu mesocarp supplemented in the feed of broilers adversely affected the performance of broilers during the initial stages of growth. KEY-WORDS:Nutritional value. Alternative food. Resistant starch. Babassu palm. RESUMOEsta pesquisa objetivou avaliar o valor nutricional e a utilização do mesocarpo de babaçu na alimentação de frangos de corte. Inicialmente, a composição química foi analisada para caracterizar o ingrediente. Em seguida dois ensaios foram conduzidos: o primeiro para determinar os valores energéticos e o segundo o nível ideal de inclusão na ração. O ensaio de metabolismo foi realizado utilizando 20 galos Legorne, distribuídos em dois tratamentos com cinco repetições de duas aves cada. O período experimental foi de dez dias, cinco dias de adaptação e cinco dias de coleta de excretas. Em seguida, 500 pintos de corte com um dia de idade foram utilizados em ensaio de crescimento, delineamento inteiramente ao acaso, com quatro tratamentos e cinco repetições. Os tratamentos consistiram de quatro níveis de inclusão do mesocarpo de babaçu: 0, 3, 6 e 9%. O ensaio de crescimento teve duração de 21 dias e foram avaliadas as respostas para consumo de ração, ganho de peso e conversão alimentar. Com base na matéria natural, o mesocarpo de babaçu apresentou 87,5%; 3,29%; 1,1%; 2,7%; 75,1% e 3.618 kcal/kg de matéria seca, proteína bruta, matéria mineral, fibra bruta, amido e energia bruta, respectivamente. A energia metabolizável aparente corrigida foi determinada em 2.671 kcal/kg, na matéria natural. O mesocarpo de babaçu, pela sua composição com baixo teor de proteína bruta e elevado teor de amido, pode ser classificado como ingrediente energético. A inclusão do mesocarpo na al...

Characteristics of Nutrition, Growth, Carcass and Meat of Male Goats Fed Babassu Mesocarp Flour

“…The linear increase of NDFI is a consequence of higher neutral detergent fiber (NDF) levels in diets with BMF. Despite the BMF having a significant starch content [19], after mesocarp extraction, the flour may contain small amounts of epicarp and endocarp, resulting in a BMF with a greater fiber content and low starch content [7,20], which is likely for the BMF used in this study.…”

Drying kinetics of ‘babassu’ mesocarp

“…mesocarp flours subjected to drying in oven and solar dryer of 'babassu' flour can be influenced by the collection period, type of soil, maturity of the fruits, species and also type of mesocarp processing, handcrafted or industrial. The contents of total protein and crude fiber were higher in the studies that used 'babassu' flour as one of the components for animal feed, such as those conducted by Silva et al (2012), who found 14.49% of protein used in bovine diet, and Carneiro et al (2013), who found 3.29 and 2.66% of protein and fiber, respectively, used in the formulation of poultry feed.…”

Análise dos parâmetros operacionais do mesocarpo do babaçu em leito fluidizado

“…The high standard of products and by-products obtained from babassu has been known for some decades, through laboratory experiments, considering each fraction of the coconut destined for some products such as, for example: epicarp (destined for charcoal with small granulometry, or alcohol , by hydrolysis of the cellulose it contains); mesocarp (produces starch, alcohol similar to that of cereals and the whole range of products derived from starch, which in turn has antiinflammatory and analgesic properties); endocarp (generates charcoal higher than some mineral coals, due to its high fixed carbon content and calorific value) and almond (intended for the production of industrial or edible oil) (Albiero et al, 2011;Carneiro et al, 2013;Chaves, 2006;de Menezes Pavlak et al, 2007;Porro, 2019;Santos, 2008;Soler et al, 2007;Sudre et al, 2015).…”
