RESUMO -Objetivou-se determinar a composição energética e aminoacídica, os coeficientes de metabolizabilidade da energia e a digestibilidade de farinhas de vísceras para aves. Utilizou-se o método da alimentação forçada com galos adultos cecectomizados. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro farinhas de vísceras (três de aves e uma de suínos e um jejum), seis repetições e um galo por unidade experimental. IntroduçãoO aumento da quantidade de resíduos produzidos pelos abatedouros e a preocupação em explorar o potencial desses resíduos como fontes proteicas, prevenindo problemas ambientais e obtendo alternativas de custo reduzido, tem tornado a farinha de vísceras ingrediente promissor na alimentação animal.

“…In case of ileal digestibility, site for digesta collection and use of appropriate indigestible markers are the main factors affecting the results. Numerous in-vivo and in-vitro methods are also used to determined AA availability and provide information regarding the entire AAs in a single test (Dalibard and Paillard, 1995). In the past, digestibility studies were conducted by precisionfeeding the intact or cecectomized cockerels and roosters or by inserting ileal cannula in pigs (Parsons, 1996).…”

“…Only the portion of dietary nutrient is used for maintenance and production which is digested, absorbed and metabolized in body and refers as the available nutrient. The term availability comprises the two words i.e., digestion and metabolism (Dalibard and Paillard, 1995;Naseer et al, 2014) so AA are bioavailable when utilized in physiological and metabolic functions of the body. Bioavailability of AA is defined as the proportion of dietary AA intake that is absorbed in a suitable chemical form necessary for protein synthesis (Batterham, 1992;Lewis and Bayley, 1995).…”

Amino acids (AA) are protein's hydrolytic products. In the recent years, poultry diets are being formulated on digestible AA (DAA) basis rather than total AA. Different techniques including precision-fed rooster assay, precision-fed cecectomized rooster assay, ileal AA digestibility and precision-fed broiler chick assay are used to determine the DAA coefficients of feed ingredients. However, nutritionists consider that the ileal digestibility in growing and adult birds is more accurate than other techniques. In all these digestibility techniques, apparent AA digestibility is corrected for endogenous AA losses to achieve standardized AA digestibility values. The digestibility values, determined using different digestibility techniques, of any feed ingredient vary. This variation in digestibility values can be minimized by adopting same digestibility technique for the estimation of DAA coefficients. Birds fed diets formulated on DAA basis resulted in better growth performance, feed efficiency and production economics. The main objective of this review is to examine the poultry's performance fed diet formulated based on the DAA.

Th e experiment was carried out on ISA 215 and Ross 308 broilers. Within each genotype, two hundred 21-day-old chickens were allocated to 4 groups of 50 birds (5 replicates of 5 males and 5 females per group). From days 22 to 42 of life the birds of both crosses were given two barley-based diets containing a high proportion of rapeseed meal and a mix of legume seeds. Th e formulation of the diet was based on total (TAA) or digestible amino acids (DAA), and diets were prepared with or without supplementing a commercial enzyme preparation containing β-glucanase, cellulase, xylanase, α-amylase and protease.Compared with ISA, Ross birds had lower (P<0.01) body weight (BW) gains, but greater breast muscle yield (151 vs 162 g/kg BW; P<0.01) and lower fat content in this muscle (10.6 vs 9.9 g/kg; P<0.01). In ISA broilers, there was an increase in the level of muscle fat in the birds receiving the DAA diet. Th e signifi cant interaction showed that the level of C18:0 acid increased in ISA females fed the DAA diet. Th e enzyme supplement increased (P≤0.05) the crude protein (CP) content and reduced (P≤0.01) the proportion of fat in ISA broilers (particularly in females; P<0.05). Th e muscle lipids of ISA chickens fed the enzyme-supplemented diet contained more C18:1 (particularly males; P<0.05) and total monounsaturated FA (P≤0.01). Ross chickens responded to the formulation based on DAA with an increase in the CP and dry matter content in the breast muscle (P≤0.01). Th e tendency towards reduced fat levels in the Ross birds fed the DAA diet was signifi cant for females (interaction; P<0.05). In contrast to ISA, in Ross birds added enzymes did not signifi cantly aff ect the proportions of the analysed muscle components.
