Sorghum grain (SG) contained more crude protein (103.5 g/kg) and ash (17.0 g/kg) but less crude fiber (17.7 g/kg) and total lipid (22.6 g/kg) than corn. The SG contained 0.37% ± 0.02 tannin, had a higher apparent metabolizable energy value than corn or wheat and contained all of the amino acids considered essential for chickens at levels in general between those of corn and wheat. Two experiments were carried out to ascertain the nutritive value of SG as a partial replacement for corn and wheat in practical poultry diets using 320 male and 320 female Cobb chicks in each. Starter (finisher) diets fed from 0–21 days (22–42 days) contained the following levels of SG: 15 (19); 30 (39); 45 (58)%. The diets were isoenergic and isonitrogenous. The inclusion of up to 45% SG in the starter diet and up to 58% in the finisher diet had no significant effect on mortality, live body weight, feed conversion or percentage of grade A carcasses.

Performance Trial

A total of 192 3-d-old male broiler chickens (Arbor Acres) were randomly assigned to six dietary treatments with eight replicates of four birds each per treatment. The treatments consisted of five levels (0, 50, 75, 100 and 125 U kg−1) of pectinase enzyme and a combination of pectinase (50 U kg−1) and α-galactosidase (6250 U kg−1) enzymes. The performance trial lasted for 2 wk. At the end of 2 wk, excreta were collected on three diets to determine nitrogen-corrected apparent metabolizable energy (AMEn). Growth rate, feed intake and feed conversion of birds fed pea diets supplemented with graded levels of pectinase enzyme were not different from their counterparts fed a diet without pectinase supplementation; however, growth rate tended to be improved (P = 0.11). Also, the AMEn values of these diets were not affected. Compared with the control diet, addition of a combination of pectinase and α-galactosidase tended to improve growth rate (P = 0.06).

Enzyme Application

Despite of high production of barley in Iran, its use in poultry diets is limited due to low energy content and problems such as sticky droppings. Barley cultivars have different nutritive value for broilers (Villamide, et al., 1997) and enzyme application may affect barley cultivar based diets differently. β-glucanase supplementation of barley based diets can eliminate β-glucan, the main anti-nutritional factor of barley, and improve nutrient digestibilities and apparent metabolizable energy. The objective of this trial is to study the β-glucanase effect on nutrient digestibilities and apparent metabolizable energy corrected for nitrogen (AMEn) of different barley cultivar based diets.

Abstract. The effect of different phytases on the performance response, nutrient utilization and tibia characteristics of chickens was investigated. The five pelleted diets were the following: positive control (PC) with added monocalcium phosphate; negative control (NC) formulated with equivalency values of phytase for Ca and digestible P; and three further diets where different phytases were individually added to the NC diet at 500 FTU/kg. The phytases were derived either from Aspergillus (phytase I), or E. coli (phytases II and III). Compared to PC, the performance parameters, as well as apparent metabolizable energy (AMEn), mineral retention, bone breaking force and tibia mineral content were suppressed by the reduction of dietary Ca and digestible P. All phytases enhanced the overall body weight gains and feed conversion ratio in comparison with NC, but none outperformed PC. Only phytase II improved AMEn compared to NC and PC group. However only phytase I outperformed NC group in terms of mineral retention and P retention was higher than phytase II and III. No significant differences were observed in fat digestibility and N retention. Bone strength among phytases did not differ and all improved this parameter compared to the NC diet. However, even though all phytases enhanced tibia minerals content, the improvement was less pronounced with phytase III. Moreover, the differences in all analysed tibia minerals between phytase III and II were significant suggesting that even among 6-phytases derived from and expressed in the same organism, different efficacy or mode of action can occur.

Rapeseed meal (RSM) is a common protein ingredient in animal diets, while the proportion of RSM in diets is limited because of its anti-nutritional factors. Fermentation based on mixed microbial strains appears to be a suitable approach to improve the nutritive value of rapeseed meal in animal feed. In this study, we evaluated the effects of fermentation on the apparent metabolizable energy (AME) values and standardized ileal digestibility (SID) of amino acids in RSM fed broilers. The AME and nitrogen-corrected apparent metabolizable energy (AMEn) values of RSM and fermented rapeseed meal (FRSM) were determined by the substitution method, with RSM and FRSM proportionally replacing the energy-yielding components of the basal diet by 30%. Results show that fermentation improved AME and AMEn of RSM from 7.44 to 8.51 MJ/kg and from 7.17 to 8.26 MJ/kg, respectively. In the second experiment, two experimental diets were formulated, with RSM and FRSM being the sole sources of amino acids. A nitrogen-free diet (NFD) was also formulated to determine endogenous amino acids losses (EAAL). Feeding on FRSM resulted in higher (p < 0.05) apparent ileal digestibility (AID) and SID of alanine, valine, isoleucine, leucine, tyrosine, lysine, arginine, and phenylalanine. No significant differences between RSM and FRSM were found for AID and SID of asparagine, histidine, threonine, serine, glutamine, praline, glycine, methionine, and cystine. FRSM had greater AMEn values and SID of amino acids compared to RSM, therefore, FRSM was nutritionally superior to RSM in broiler diets.

Four experiments were carried out to ascertain the nutritive value and quality of oat groats (OG) as a partial replacement for corn and total replacement for wheat in practical diets for broiler chicken using one commercial broiler genotype, Cobb. In each of experiments 1 and 2, 360 day-old chicks of each sex were housed in Petersime batteries and fed starter (1–21 days) and finisher (23–42 days) diets containing 0, 200 and 400 g of Eastern (E) OG or Western (W) OG/kg. In each of experiments 3 and 4, 320 day-old chicks of each sex were housed in eight floor pens and fed starter diets containing 0, 400 and 600 g EOG/kg and finisher diets containing 0, 400, 600 and 800 g EOG/kg. Feeding up to 600 g/kg OG in starter diets and 800 g/kg in finisher diets had no significant adverse effect on biological performance or monetary returns.

Although the benefits of phytase are well documented, the purpose of this study was to determine the effect of supplemented phytase on pea-based diets in poultry, as research is lacking on pea diets. A 21-day feeding trial using male broiler chicks on the day of hatch was conducted to assess the effects of adding four levels of dietary microbial phytase (0.0, 0.1, 0.3 and 0.9 g/kg diet; with respective activity levels of 0, 500, 1500 and 4500 FTU or phytase units) to a pea-based diet on bird productivity and digestibility. The responses were evaluated in terms of broiler performance, nutrient digestibility and apparent metabolizable energy (AME). This research demonstrated that digestibility of ash and starch increased with phytase supplementation. Protein and fat digestibility remained relatively constant, but an increase in apparent metabolizable energy (AME) was seen. The performance of broilers also improved as increased weekly gains attributable to phytase were seen through improved feed conversion. The results of this research are indicative that phytase supplementation in poultry pea-based diets has a positive impact.

Whole Seed

Sunflower (Helianthus annuus L.) is one of the most widely cultivated oilseeds in the world and ranks third in importance as a source of vegetable oil. In our experiment, full-fat sunflower seed (FFSS) had 180 g/kg CP, 380 g/kg EE, and 143 g/kg CF. Among the various oilseeds available on the market, FFSS contains more ether extract (EE) and is available at a relatively low price. This high EE content contributes to a high ME per unit or high energy density of feed. The increased production and availability of hybrid FFSS coupled with its oil content make FFSS a potentially desirable ingredient in poultry feeds. In the last few years, unextracted whole seed has been used as a feed ingredient in poultry diets. This experiment was conducted to determine the apparent metabolizable energy (AMEn) of FFSS in broiler chickens.

Faba Beans

The effects of autoclaving on the composition and nutritive value of a sample of faba beans for growing broilers were studied. Whole beans were heat-treated at 121 C for 0, 15, 30, 45 or 60 min in trial 1 and for 0, 30 or 60 min in trial 2. Heated beans were incorporated at 25% level by replacing soybean meal and ground wheat in control diets containing 20.2 and 17.0% of protein in trials 1 and 2, respectively. Heat treatment for 45 and 60 min resulted in a slight decrease in the protein (N × 6.25), cystine and basic amino acid content of the beans, but increased the metabolizable energy content by about 15% (2.57 vs. 2.20 kcal/g at 90% dry matter). Growth rate, feed intake and feed conversion efficiency were not affected by the presence of faba beans in broiler rations. Although heating the beans marginally improved their nutritive value it may not be economical on a practical basis.

Ad Libitum Feeding

Two experiments were carried out to ascertain the nutritional value of potato waste meal (PW) as a replacement for corn in practical poultry diets using 320 male and 320 female Cobb chicks fed from 1-day-old to 46 days (exp. 1) and 49 days (exp. 2) a basal cereal-based diet containing soybean and fishmeals or test diets each containing 50 g, 100 g, 150 g, 200 g and 300 g PW/kg. In both experiments, the diets were analyzed for elemental and amino acid composition, and the growth responses on the test diets were evaluated individually over a period of 28 days and 46 days or 49 days of ad libitum feeding. Although PW appeared limiting with respect to methionine and cystine, arginine and the aromatic amino acids, it was found that upon supplementation with methionine (0.5 g/kg), the test mixtures exhibited a synergistic effect compared with controls, and that this potato byproduct can be considered a good substitute ingredient for a proportion (200 g/kg) of the ground corn in a practical diet for broiler chickens. Feeding PW at a rate of up to 200 g/kg resulted in optimum biological response and monetary returns. The inclusion of up to 300 g/kg PW in the diets did not increase wetness of the litter or hardness of pellets, two factors reported earlier which could limit the use of PW in animal diets.
