The influence of meat-and-bone meal and exogenous phytase on growth performance, bone mineralisation and digestibility coefficients of protein (N), amino acids and starch in broiler chickens

Enzymes benefit digestion and absorption of the ingredients and their addition to an animal-origin meal (AOM) can improve its nutritional quality. This research aimed to evaluate the effect of protease on nutrient digestibility, amino acids, and metabolism of AOM energy for broilers. Four hundred and eighty broiler chickens were distributed in a completely randomized design (4 × 2 factorial scheme), eight treatments, six replicates containing 10 birds/replicate. Treatments consisted of poultry viscera meal, swine viscera meal (SVM), bovine meat and bone meal, and basal diet; with and without protease addition. Two tests were performed. In the first test, the total excreta collection method was used with birds at 13 to 20 days of age and 25% of the reference feed was replaced by AOM. In the second test, a protein-free diet was administered to birds at 21 to 24 days of age and AOM replaced 25% of the starch. The inclusion of protease increased the apparent metabolizable energy corrected for nitrogen balance of SVM by 15.99% and the apparent metabolizable crude energy by 5.7%, and it also raised the coefficient of true ileal digestibility of the amino acids in the AOMs by 5.67% on average. The inclusion of protease improved the apparent metabolizable crude energy of AOMs, apparent metabolizable dry matter of bovine meat and bone meal, coefficient of true ileal digestibility of essential amino acids, and apparent metabolizable energy corrected for nitrogen balance of SVM. Dietary supplementation of protease may be a potential strategy to improve the digestibility of amino acids for broilers, a possibility of using animal-origin meals as a protein source of diets.

Abstract This study was conducted to determine the standardized ileal digestibility (SID) of amino acids (AA) in hydrolyzed feather meal (HFM), flash dried poultry protein (FDPP), poultry meal (PM), and meat and bone meal (MBM) fed to broiler chickens and pigs. Four semi-purified diets and a nitrogen-free diet were prepared. Exp. 1 was conducted with 416 male broiler chickens (initial body weight [BW] = 705 ± 100.0 g) at d 18 post-hatching in a randomized complete block design. Birds were fed diets for 5 d and then euthanized to collect ileal digesta. In Exp. 2, ten barrows (initial BW = 22.1 ± 1.59 kg) surgically fitted with T-cannulas at the distal ileum were assigned to duplicate 5 × 4 incomplete Latin square design with 5 diets and 4 periods. There were 5-d adaptation and 2-d ileal digesta collection periods in each experimental period. Data were analyzed as a 2 × 4 factorial arrangement with the effects of species (i.e., broiler chickens and pigs) and four experimental diets. There were interactions (P < 0.05) in the SID of His, Lys, Thr, Trp, and Val between diets and species. In broiler chickens, the SID of Lys in MBM was greater (P < 0.05) than HFM and FDPP but was not different from PM. Pigs fed MBM had greater (P < 0.05) SID of Lys than HFM, FDPP, and PM. In broiler chickens, the SID of His, Thr, and Trp in FDPP and PM were greater (P < 0.05) than HFM but was less (P < 0.05) than MBM. In pigs, the SID of His, Thr, and Trp in FDPP and PM were greater (P < 0.05) than HFM but was not different from MBM. In conclusion, differences in the SID of AA among animal protein sources were affected by species of monogastric animals.

This study was aimed to determine the effects of protease supplementation in diets with agricultural-livestock by products on the growth performance in broiler chickens. The commercial protease used in current study was produced by Bacillus licheniformis which based on keratinase. The treatment diets were a control basal diet without agricultural-livestock by-products and protease supplementation (P1); P1 + 0.05% protease; basal diet with meat bone meal (MBM) and distiller’s dried grain with soluble (DDGS) suppementation (P3); P3 + 0.05% protease (P4); basal diet with hydrolized chicken feather meal (HCFM) and DDGS supplementation (P5); P5 + 0.05% protease. The obtained data were statistically analyzed using Complete Randomized Design, and analyzed subsequently by Orthogonal Contrats Test. Results showed that protease supplementation in the diets containing agricultural-livestock by-products did not affect growth performance of broiler chickens in starter phase and overall age phase. However, in diets containing MBM, protease supplementation reduced the nett gain and feed conversion ratio (FCR) in finisher phase (P<0.05). In diets containing HCFM, protease supplementation increased nett gain and FCR (P<0.05), compared to those of containing MBM. It could be concluded that qualified HCFM, MBM, and DDGS can be used as alternatives for protein-energy source feed stuffs in starter phase, as they did not reduce growth performance of broiler chickens. Protease used in this study might be more effective in diets containing HCFM than those of containing MBM and DDGS.Keywords: Agricultural-livestock by-products, Broilers chickens, Growth performance, Protease.
