“…The addition of enzymes to the feeds did not have the expected effects of reducing excrement moisture content (Table 3), as reported by other authors (Salobir et al, 1994;Al Bustary, 1996;Marquardt et al, 1996).…”

“…The effects of enzymes have been studied mainly on feeds containing substantial amounts of barley or rye, and better weight gains and feed utilization were achieved (Rotter et al, 1990;Mohammed, 1995;Al Bustary, 1996;Kaoma et al, 1996). In the case of feeds containing triticale or wheat, the addition of enzymes also had favourable effects (Salobir et al, 1994;Richter and Miiller, 1995) .…”

“…Enzymes are added to improve the economy of feeding, but their effectiveness depends on the type and amount of enzymes as well as on the substrate (Muramatsu et al, 1992;Brenes et al, 1993;Jeroch et al, 1995;Mohammed, 1995;Al Bustary, 1996;Faruga et al, 1996;Kaoma et al, 1996;Marquardt et al, 1996) .…”

The study was carried out on 456 one-day old BUT-9 torn poults divided into 4 groups (3 replicates x 38 poults per group) fattened until the age of 154 days.The control group was fed a wheat-maize feed. These cereals were replaced by triticale and barley in the experimental diets. Mixture 1 was given without enzymatic supplements, feeds 2 and 3 contained different enzyme preparations. Less soya oil was added to enzyme-supplemented feeds, on the assumption that the addition of enzymes can increase the AMEN of triticale and wheat by 6%, of barley by 10%.Body weight and feed utilization indexes, nutrient digestibility and dressing percentage were similar in all of the groups. Enzyme-supplemented feeds were more economical in comparison with the control triticale-barley diets (by 5.0-7.5%) and wheat-maize diets (by 8.5-11.0%).

“…Barley, wheat, rye, and oats have high levels of NSP which are known to lead to increased digesta viscosity, decreased digeta pas-sage rate, digestive enzymatic activities and nutrient digestibility, depressed feed conversion efficiency, and growth rate of the birds (Bedford and Schulze, 1998). Specific exogenous enzymes have the ability to break down NSP and reduce digesta viscosity, increase digesta passage rate, and improve bird performance (Almirall et al, 1995;Bustany, 1996;Choct et al, 1996Choct et al, , 1999Jorgensen et al, 1996;Leeson et al, 2000;Mathlouthi et al, 2003;Wu et al, 2004).…”

Factors Affecting Intestinal Health in Poultry

The gastrointestinal (GI) tract has the most extensive exposed surface in the body and is constantly exposed to a wide variety of potentially harmful substances. The GI tract acts as a selective barrier between the tissues of the bird and its luminal environment. This barrier is composed of physical, chemical, immunological, and microbiological components. A wide range of factors associated with diet and infectious disease agents can negatively affect the delicate balance among the components of the chicken gut and, as a result, affect health status and production performance of birds in commercial poultry operations. Phasing out of antibiotic growth promoters from poultry diets in Europe and recent moves toward reduction or removal of these compounds in other parts of the world including North America will likely change the microbial profile of the GI tract environment in commercial poultry. This paper reviews the GI tract from developmental, immunological, and microbial standpoints and then discusses factors that can affect health status of this system. Necrotic enteritis and coccidiosis and their interactions, and possible consequences of antibiotic growth promoter removal from poultry diets with respect to these diseases, are discussed in more detail.

“…Feeds used for broiler production are often (steam and/or double) pelleted and the ability of enzymes to withstand this heat treatment is questioned (Al Bustany, 1996). Controversy exits on the extent of the loss in enzyme activity and on the feed properties that can diminish these losses.…”

ABSTRACT:The present study was conducted to determine the effects of different pelleting temperature on tibia mineralization, calcium, phosphorus content of serum and growth performance of broilers fed phytase-supplemented diets. The basal experimental diet type was typical maize-soybean meal. The basal diet was supplemented with a microbial 6-phytase (Novo CT: coated thermostable granulate, from Novo Nordisk A/S, Denmark) at 500 Phytase Units (FTU) per kg of feed before pelleting. The diets were pelleted at 65, 75, or 85°C except the basal mash diet as the control. The experimental diets were used from 0 to 6 weeks of age of birds. Dry matter, crude ash, Ca, total P, Na, K and Mg, Zn, Fe, Mn, Cu contents of tibia were not affected by the pelleting temperature. No effects of pelleting temperatures on Ca content in the serum were found out. However, P content in the serum was increased by feeding the diet pelleted at 65°C as compared to the control and other treatments. Pelleting at 65 and 75°C had a significant positive effect on body weights and body weight gains of broilers. It was concluded that the best pelleting temperature was 65°C. It is to note that the temperature of 85°C damages enzymatic activity.
