Enzyme Supplementation

This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) and protein resources (soy or rapeseed meals) on gut morphology and protein digestibility of broiler chickens. Three hundred eighty-four male Ross-308 broiler chickens were used with a 23 factorial arrangement with treatments according to a completely randomized design. The morphological examinations of the intestine were carried out on 1-cm long excised segments from duodenum, jejunum and ileum. Adding wheat to the diet increased small intestine length in birds compared to other feedstuffs (P <0.05). Duodenum crypt depth and jejunum villi length were also higher in groups fed with rations containing wheat (P <0.05). Groups that received thyme essential oil and enzyme supplementation had increased length of the duodenum (P <0.05). However, the two- and three-factor interaction effects were not significant. Protein digestibility was not affected by treatment (P >0.05). Feeding wheat to broiler chickens may increase the surface area for nutrient absorption in the small intestine as compensation for the anti-nutritive activity of non-starch polysaccharides in wheat-based diets. Wheat based diets are expected to be acceptable for broilers when supplemented with appropriate enzymes or thyme essential oil.

Enzyme Supplementation

We evaluated the influence of enzymatic supplementation on the growth performance and cecal microbiota of broilers. A total of 2160 1-day-old male chicks were used in a 3 × 2 × 2 factorial arrangement (three corn hybrids, two drying temperatures −80 and 110 °C, with or without the inclusion of an enzymatic blend (amylase, xylanase, and protease) (20 birds/pen, n = 9). For all performance and digestibility parameters, we observed, in general, isolated effects of the corn hybrids and drying temperature. Birds that received the enzymatic blend in the diet showed better weight gain from 1 to 21 days (d) and better digestibility coefficients of nutrients at 42 d. Birds fed diets with corn dried at 80 °C showed a better feed conversion ratio from 1 to 42 d. At 21 d of age, enzymatic supplementation had positive effects on jejunum morphology. Enzyme supplementation increased the abundance of the phylum Tenericutes, class Bacilli and Mollicutes, reduced Clostridia, and increased the abundances of the families Lactobacillaceae, Anaeroplasmataceae, and O_RF39;F. In conclusion, the addition of amylase, xylanase, and protease led to a better nutrient digestibility, performance, and intestinal morphology. In addition, enzyme supplementation changed the diversity, composition, and predicted function of the cecal microbiota at d 21.

The study investigated gut ecology and morphology of the Indonesian indigenous crossbred chickens (IICC) supplemented with the combination of formic acid and Saccharomyces cerevisiae. Two hundreds day-old IICC were distributed to T0 (control diet), T1 (T0 + 0.2% formic acid), T2 (T0 + 0.3% S. cerevisiae), T3 (T0 + 0.2% formic acid and 0.3% S. cerevisiae). Excreta was collected at week 8, while intestinal ecology and morphology were determined at week 9. In duodenum, T3 chicks showed higher and wider (P<0.05) villi. The T2 and T3 chicks showed deeper (P<0.05) crypt than that of T0. The jejunal villi was higher (P<0.05) in T3 than in T0. The T3 chicks had deeper (P<0.05) crypt compared to other groups. In ileum, the villi height was lowest (P<0.05) in T0. The crypt was deeper (P<0.05) in T3 than in other. Crude protein digestibility coefficient was highest (P<0.05), while fecal protein was loswest (P<0.05) in T1 than in other groups. Compared to T0, the treated IICC showed higher (P<0.05) weight gain and feed intake with T3 had the highest gain and intake but gain:feed rasio was the lowest (P>0.05). IIn conclusion, the inclusion of formic acid and S. cerevisiae in diets improved intestinal ecology and morphology. The IICC chickens fed with formic acid and S. cerevisiae exhibited improved growth performance and nutrient digestibility.

Micro Organisms

It is well known that alternative food additives are being researched following the prohibition of the addition of antibiotics to poultry feed as growth factors. Recently, antimicrobial peptides (AMPs) have been considered as alternatives to antibiotics. AMPs, produced by bacteria, insects, amphibians and mammals, as well as by chemical synthesis. In particular, their natural antimicrobial properties and their low tendency to create resistance in micro-organisms suggest that they might be a good alternative to antibiotics. They are not only effective against bacteria, but are also known to be effective against fungi and viruses. In studies on pigs and broiler chickens, they have been shown to be beneficial effects on growth performance, nutrient digestibility, the immune system, intestinal morphology and gut microbiota. Antimicrobial peptides are small biological molecules formed from 12-60 amino acids. AMPs have been reported to kill bacteria, in particular those showing resistance to multiple antibiotics. AMPs block the development of harmful bacteria while encouraging the growth of beneficial bacteria. For instance, it has been reported that sublancin reduces the Clostridium perfringens count while increasing the numbers of Lactobacilli. Furthermore, they have been proved to have a strong effect against Staphylococcus aureus and Pseudomonas aeruginosa. Some of the AMPs used in broiler chicken feeding are sublancin, secropin, magainin, nisin and defensin. These peptides can be used by adding them to feed or to drinking water. This review has attempted to find an answer to the question of whether AMPs added to the feed of broiler chickens can be an alternative to antibiotics by examining previous studies.

Amino Acid Combination

In comparison to 44% crude protein of soybean meal (SBM), the protein content of rapeseed meal (RSM) is about 35-40% and has a physiologically suitable amino acid combination in animal nutrition, but RSM contains nutritionally unfavourable substances such as glucosinolates, sinapin, tannin, phytate and non starch polysaccharides (NSP) (Kocher et al., 2000). Enzymes have the potential to be used in diets contain antinutritional factors that hinder nutrient availability. NSPs include cellulose, B-glucans, arabinoxylans, and pectins that may increase viscosity of digesta and cause a decrease in nutrient digestibility and performance of broiler chickens. Phytase activity from digestive secretions, some feed ingredients, resident bacteria, exogenous microorganisms, or both resident bacteria and exogenous microorganisms is present in the digestive tract of broiler chickens (Kornegay, 2001), but its efficiency at a practical level is very low. It is accepted that broilers lack sufficient levels of phytase activity to effectively hydrolyse the phytate molecule. Phytate-bound P is not well digested, so inorganic P is added to broiler diets that increased feed costs (Lescoat et al., 2005). The purpose of this study was to investigate the replacement value of SBM with locally grown RSM and two types of enzymes (NSP-degrading and phytase) on performance of broiler chickens.

AbstractA 42-d study was conducted to investigate the effects of an emulsifier supplementation (de-oiled soyabean lecithin (DSL)) of diets with different levels of metabolisable energy (ME) and various sources of fat on growth performance, nutrient digestibility, blood profile and jejunal morphology of broiler chickens. Diets were arranged factorially (2 × 2 × 2) and consisted of two concentrations of ME (normal and low), two fat sources (soyabean oil (SO) and poultry fat (PF)) and two levels of DSL supplementation (0 and 1 g/kg). A total of 800 1-d-old male broiler chickens were assigned to eight treatments with five replicates/treatment. The results showed the supplemental DSL caused improvements in the overall feed conversion ratio, fat digestibility and jejunal villus height:crypt depth ratio, but the magnitude of the responses was greater in the PF-containing diets, resulting in significant fat × DSL interactions (P<0·05). Abdominal fat percentage was also reduced by the PF-containing diet, but the response was greater in the normal ME diet, resulting in a significant ME × fat interaction (P = 0·048). Dietary DSL supplementation also increased nitrogen-corrected apparent ME values but decreased blood TAG (P = 0·041) and LDL (P = 0·049) concentrations, regardless of the source of fat used or the ME values in the diet. In conclusion, the present study suggests that the improvements in growth performance, fat digestibility and intestinal morphology that can be achieved with DSL supplementation are highly dependent on the degree of saturation of lipid incorporated into broiler chicken diets.
