“…The chemical composition of maize grain and excreta was determined according to AOAC (2005), while α-amino nitrogen in feed and excreta was determined according to method of Pahle et al (1983) modified by Barteczko et al (1993). The method is based on the hydrolysis of protein in feed and faeces in hydrochloric acid.…”

“…The ATTD of protein was calculated according to Pahle et al (1983) with the use of α-amino nitrogen determined in feed and excreta. Apparent metabolizable energy corrected to zero nitrogen balance (AME N ) was calculated according to the formula of Hill and Anderson (1958): AME N = AME -(BN g x 0.0365) where: BN (N retained), g = N intake, g -N excreta, g Means were compared for main effects using one-way analysis of variance and Tukey's test.…”

The objective of the study was to determine the nutritive value of grain of different maize cultivars for broiler chickens. The study involved 45 Ross 308 broilers (9 groups with 5 chickens per group) aged 42 to 49 days. Chickens were fed the grain of maize cultivars Pioneer PR39H84, Smok, Arobase, Moncada, Pioneer PR39G12, Eurostar, Opoka, Boruta, and Nysa ad libitum. The cultivars of maize differed in basic chemical composition, contents of amino acid and fibre fractions, as well as fatty acid profiles. Variations in chemical composition among different maize cultivars had an effect on the extent of basic nutrient digestion and on the energy value of grain in broiler chickens. For practical utilization of maize in broiler feed mixtures it will be important to determine the content of insoluble fibre, as it is negatively correlated with nutrient digestibility and the AME N value of grain (r=-0.69; P<0.05).

Apparent TREATMENTS OF RAPESEED FOR BROILERS 57 crude protein digestibility was calculated from total a-amino-N being present in feed and excreta employing the ninhydrin reaction (Pahle et al, 1983).

The effect of different technical treatments of rapeseed on its feed value for broilers and laying hens was the object of the study. The technical treatments comprised different grinding procedures (whole seed, roller mill--coarse and fine adjustment, flake mill) resulting in different average particle sizes of the ground seed and thermal treatments of flaked seed (hydrothermal treatment, micronizer, jet sploder). Each thermal treatment was carried out at two temperatures. A marked increase in the digestibility of organic matter and of the AMEN content was observed as the average particle size of the seed was decreased to < or = 0.56 mm and was much more pronounced for the broilers. AMEN contents of 21.1 to 22 and 22.6 to 23 MJ/kg DM were observed at this particle sizes for broilers and hens, respectively. Thermal treatment of rapeseed improved the apparent crude fat digestibility slightly whereas the apparent crude protein digestibility tended to decrease especially at the higher temperatures. This resulted in inconsistent changes in the apparent digestibility of the organic matter and the AMEN content. Only the treatment with hot air (jet sploder) seemed to have preferential effects on the feed value for both broilers and hens. For the thermal treatments AMEN contents ranged from 18.8 to 21.9 and 19.0 to 24.3 MJ/Kg DM for broilers and hens, respectively.

“…Whereas the nitrogen analysis (semimicro Kjeldahl method) and chemical separation of nitrogen in faeces and urine (a-NH 2 -N method of Pahle et al, 1983, modified by Priebs et al, 1987 was performed in the fresh excrements, for the other analyses the freeze dried excrements were used. The energy content of feed and excrements was determined with an adiabatic bomb calorimeter (C400, Janke and Kunkel GmbH, Staufen, Germany) followed by gravimetric determination of the carbon dioxide to calculate the carbon content.…”

Energy balances of cocks and chickens were measured using the nitrogen-carbon-balance method. In Experiment 1 twelve adult White Leghorn cocks were fed alternately on a basal ration or on a supplemental ration composed of 75% basal diet and 25% carbohydrate source as a supplement. In Experiment 2 six groups of 12 male broiler chickens were fed successively on two diets each with different carbohydrate sources (40% of DM) and on two energy levels. The investigated carbohydrate sources were glucose, fructose, sucrose, maize starch, raw and steamed potato starch, dried sugar beet pulp, tapioca, wheat, maize, rye and barley. In both experiments the energy digestibility of the diets with raw potato starch, beet pulp and barley was significantly lower compared to the other diets. Digestibility of those ranged from 88 to 81%. By simple linear regression no significant differences in efficiency of utilisation of ME of the diets between the carbohydrate sources sugars, starches and cereal grains could be proved. The corresponding MEm values agreed very close among the diets (411 to 429 kJ.kg BW-0.75.d-1).
