“…According to Pucci et al (2010), the cause of the lower consumption of micropelleted food is due to the glycostatic factor, where the food receives high temperatures during its production, which facilitates starch digestibility. There is also the breakdown of some organelles, making carbohydrates and proteins more palatable for birds.…”

The objective of this work was to evaluate the effects of two types of incubation and two types of feeding on the performance of chickens and intestinal development of chicks during the pre-starter phase (1 to 7 days of age). One-year-old male Ross® chicks were used. The experimental design was a randomized complete block design, in a 2x2 factorial design, with two types of feed processing (bran and micropelleted) and two types of incubation machines (single and multiple stage), totaling four treatments, with four treatment repetitions each. Twelve birds per experimental unit were used, totaling 192 animals. Performance evaluations were conducted, such as mean weight, weight gain, feed intake, feed conversion, bowel weight and size, and percentage of intestine in relation to live weight. Histomorphometric tests on the height of the villi and depth of the duodenal crypts were also performed. The two incubation machines did not influence any of the analyzed variables. Even though both had the same composition, the micropelleted feed resulted in positive gains for the performance variables: average weight, weight gain, feed intake, and feed conversion when compared to the meal, but was unable to significantly influence the morphometric measurements of the duodenum of chicks in the pre-starter phase.

“…Those authors suggest that by adopting additional supply, an inclusion method used for Enzyme Blend, differences can be reduced, consequently reducing the likelihood of significant differences. Other authors, however, observed an improvement (p<0.05) in the feed conversion of broilers fed corn and soybean mealbased diets supplemented with an enzyme complex under the same inclusion method (Pucci et al, 2010).…”

This experiment was undertaken to compare the effects of using the Enzymmix F product with a Brazilian enzyme blend in diets with different nutritional levels. A total of 1,080 male broiler chicks were distributed into a randomized-block design with a 3 × 2 factorial arrangement consisting of three enzyme complexes (Enzyme Blend, Enzymmix F, and the combination of both) and two nutritional levels (regular and reduced). We evaluated the birds' performance in the periods of 1 to 21 and 1 to 42 days of age. The yields of carcass and cuts and intestinal integrity were evaluated at 45 days of age. During the analyzed periods, no significant difference was observed for the performance parameters considering the "enzyme" factor. However, the reduction in the nutritional level of the diet resulted in inferior performance in both periods. There was no statistical difference for the yields (%) of carcass and cuts. Enzymmix F provided the greatest villus height in the jejunum segment. The use of the Enzyme Blend in the nutritionally reduced diet led to a lower crypt depth. In conclusion, Enzymmix F increased the weight of wings (g) and the villus height in the jejunum.

“…However, Pucci et al (2010) showed that supplemented EC mixture (amylase, cellulase and protease) to broilers diets based on corn and soybean meal significantly (P<0.05) improved FCR. Angel et al (2011) reported that the as-similation of nutrients by the birds especially in the early stage of life improved by supplementation of endogenous enzyme production which in turn improves as a result of the addition of exogenous enzymes.…”

The effect of supplemented pectinase (PE) and protease (CIBENZA® DP100) (P) individually or mixture (PEP) and either on low crude protein (CP) and low metabolizable energy (ME) were studied on growth performance, carcass characteristics and meat quality of Arbor Acres broiler chickens. Two experiments were conducted in current study; experiments 1 (EXP1) evaluated the effects of PE and/or P supplementation to standard corn-soybean broiler diet (STD). while experiment 2 (EXP2) examined the PEP supplemented to different levels of low CP (low 10 or 15 %) and low ME diets (lower 100 or 150 kcal/kg) than control (L10%-100, L10%-150, L15%-100, L15%-150). The obtained results were: the EXP1 showed that significant improvement in feed conversion ratio (FCR) for chicken in P treatment by 8.38 and 5.75 % in compared to control and PE, respectively. Also, chicken in PEP treatment significantly (P<0.05) increased dressing % by 7.89% and drum stick by 9.27% compared to control. All supplementation had significant improvement in total protein (TP) level in broiler meat. PE and PEP enhance meat oxidative by decreased malondialdehyde (MDA) by 28.15 and 19.87 %, respectively and improve meat quality by decreased low density lipoprotein (LDL) by 7.69 and 4.73 %, respectively. The EXP2 observed chicks fed on low ME and low CP diet significantly decreased total body weight gain (BWG) with increased in total feed intake and FCR. Chicken treated by PEP had significant increased on final body weight, BWG and improved FCR for control and L10%-100. Chicks fed on PEP+L10%-100 and PEP+STD significantly gained the highest dressing followed by L10%-100. These results in general show positive effect of EXP1 witch improved FCR by supplemented P however PEP supplementation increased dressing % and drum stick %. Both supplementation enhanced meat TP and decreased meat MDA. The EXP2 witch used low CP and low ME with PEP supplementation enhance especially for L10%-100 and control. The chemical quality of produced meat as the concentrations of MDA and LDL were decreased and increased meat TP.
