“…However, the addition of proteases generated the same values for percentage and thickness of the eggshell and specific gravity of eggs as compared to hens fed the control diet. These results differ from those found by Resende et al (2017), who did not find any significant differences in the percentage and thickness of eggshell, Haugh unit, and specific gravity of eggs from Hy-Line Brown hens from 28 to 40 weeks old fed diets with or without the enzyme complex (β-glucanases, β-xylanases, cellulases, and phytases) in the proportion of 50g/t.…”

“…Some improvement in the hens' performance was observed in this study, especially regarding the production, mass, and conversion into egg mass with supplementation of protease B, which promoted a result similar to that of the control diet. Resende et al (2017) also found similar results, since they observed that the inclusion of an enzyme complex (β-glucanases, β-xylanases, cellulases, and phytases) at the dose of 50g/t in diets of Hy-Line Brown hens from 28 to 40 weeks old, provided improved rates for egg production, egg mass, conversion by dozen, and egg mass compared to hens fed diets with low nutritional density. Vieira Filho et al (2015) observed an increase in the laying rate by adding 500 g ton-1 of protease (100 Ug-1) to diets of Isa Brown commercial layers at 44 weeks old with reduced nutritional levels.…”

This work was developed to evaluate the impact of the addition of proteases on the performance characteristics, egg quality, relative weight of digestive organs, and intestinal morphometry of laying hens. 390 Hy Line W36® hens were allocated into five treatments and six replicates with 13 animals. The treatments were: 1) Control (standard formulation), 2) Negative control A -NCA (nutritional reduction according to protease A matrix), 3) Negative control B -NCB (nutritional reduction according to protease B matrix), 4) NCA+protease A (0.250 g/kg of feed) and 5) NCB+protease B (0.125 g/kg of feed). Hens fed the NCA, NCB, and NCA+protease A diets showed reductions in feed intake and egg mass. The addition of protease B provided better results for egg production in both percentage and per dozen as compared to the group fed with the NCA+protease A diets. The hens subjected to diets NCA and NCB showed eggs with a reduced eggshell and thickness percentage. However, supplementation with proteases A and B improved these parameters to values similar to the controls. There was no significant effect of the treatments on the relative weight of the liver, proventricle, gizzard, pancreas, and small intestine. However, the addition of protease A resulted in a decreased value for the relative weight of the large intestine. The jejunum and ileum crypt depths were, respectively, smaller in hens fed the control diet in relation to the NCB diet and the NCA and NCB diets. As it can be concluded, Protease B supplementation provided the best performance results.

“…This is because the main function of L-carnitine that doesn't affect feed consumption is to help the metabolism needed to oxidize long-chain fatty acids in mitochondria so that the utilization of fat as an energy source can be optimal [5] so that it has no direct effect on consumption. Exogenous enzymes such as cellulase did not significantly reduce feed consumption as they are primarily used to improve nutrient digestibility, especially when the diet is high in fiber [9].…”

“…Enzymes can be used as a dietary strategy to improve bird performance and profitability by improving the digestion of feed components (proteins, amino acids, starches, lipids, and energy) [8]. The addition of carbohydrase enzymes improves nutrient utilization, particularly energy utilization [9]. Cellulase is a carbohydrase enzyme that can be used to increase nutrient digestibility by catalyzing the conversion of cellulose to glucose, which can be used as a potential energy source [3,4], as well as to reduce environmental impact due to undigested nutrients [1].…”

Muscovy duck in Indonesia has good potential to be developed as a meat producer, but currently its production and performance are still relatively low. additional feed is needed to increase it, such as cellulase enzymes, L-carnitine, and lemuru fish oil. where this combination, enzymes can increase nutrient digestibility, fish oil which is rich in unsaturated fatty acids and L-carnitine as a metabolic facilitator needed to oxidize long chain fatty acids. This research was conducted to investigate the effect of supplementing cellulase, carnitine and fish oil in feed on performance, EPA and DHA composition of Muscovy duck meat. In total, 120 Muscovy ducks in grower period were allocated to 4 dietary treatments with 5 replicates of 6 ducks. The treatments consisted of T0 = basal ration, T1 = T0 supplemented with 0.1% cellulase, T2 = T1 supplemented with L-carnitine 40 ppm, and T3 = T2 supplemented with 4% lemuru fish oil. The dietary treatments were fed for 90 days. The results of study showed that the effects of supplementing fish oil and L-carnitine in rations containing cellulase enzyme have a significant value (P<0.01) on the performance (feed consumption, daily body weight gain, feed conversion and IOFC) of male Muscovy duck grower phase and have a significant value (P<0.01) on EPA and DHA level in Muscovy duck meat. The supplementation can decrease feed consumption, meanwhile it increase daily body weight gain, improve feed conversion ratio, increase IOFC value, EPA and DHA level.

“…El PA, presenta un alto contenido en fósforo fítico (1,89 %), es más barato que el maíz y tiene un uso limitado en los alimentos balanceados, debido a su alto contenido en fibra, ácidos grasos insaturados (AGI) y en fitatos [28]. La adición de enzimas exógenas (1,4-β endoxilanasa y fitasa) en dietas con alto contenido de fibra mejoraron los índices productivos y de calidad en huevo, de acuerdo a un reporte realizado por Amerah y col. [3], Khan y col. [18] y Resende y col. [31]. El uso de enzimas (xilanasa, proteasa y fitasa) mejoraron la digestibilidad del almidón, grasa y proteínas, aportando más disponibilidad de nutrientes en el lumen intestinal y mejora de la absorción [3].…”

La utilización de insumos en la industria avícola como maíz y soya están cada vez más escasos y costosos. Para ser más eficientes, es necesario aprovechar los subproductos locales en las dietas de los animales. En tal sentido, se evaluó el efecto de utilizar diferentes niveles de polvillo de arroz (PA) y arroz quebrado (AQ) en la dieta de gallinas ponedoras Lohmann Brown – Classic: Dieta control (DC, en base a maíz y soya), Tratamiento 1 (T1) (50 gramos (g)/ kilogramos (kg) PA y 150 g·kg -1 AQ), Tratamiento 2 (T2) (50 g·kg -1 PA y 300 g·kg -1 AQ), Tratamiento 3 (T3) (100 g·kg -1 PA y 150 g·kg -1 AQ), Tratamiento 4 (T4) (100 g·kg -1 PA y 300 g·kg -1 AQ) con el uso de enzimas exógenas, en los parámetros productivos, calidad de huevo y evaluación económica. El uso de PA + AQ incrementó de manera significativa (P<0,05) el consumo de alimento, postura y masa de huevo, sin embargo, el color de yema se redujo con el uso de PA y AQ. La evaluación económica demostró que en el T4 (10 % PA + 30 % AQ) se redujo el costo promedio por kg de huevo, aunque con un mayor consumo de alimento, se logró un menor costo promedio por alimento y por ello un mayor margen bruto promedio de 33,55 % en T4 comparado con la DC. Se puede concluir que el uso de subproductos de arroz (PA + AQ) con el uso de enzimas exógenas mejoran los índices productivos e índices económicos en la dieta de gallinas ponedoras.
