To test the hypothesis that inclusion of whole cereals in the diet of broiler chickens reduces the severity of a coccidial infection, the effects were investigated, in birds infected with Eimeria acervulina, of feeding a complete pelleted control food, the control food diluted with whole wheat (400 g/kg), or a diet in which ground wheat in the pellets was substituted with whole wheat (400 g/kg) so as to achieve the same composition as the control diet. In the weeks prior to and after infection, (days 14–20 and days 21–27), no significant differences in performance were observed between birds fed the complete pellet and substituted feeds. Birds fed the diluted feeds had significantly lower gains per unit of feed and numerically lower weight gains than the birds fed the control and substituted feeds during this period. No significant differences in performance were observed between treatments from days 28–34. Diluting feeds with whole wheat (400 g/kg) significantly increased ileal digesta viscosity levels, compared with feeding the control and substituted feeds in birds dissected on day 21, although no significant differences in digesta viscosity levels were observed in birds dissected on day 35. Whole wheat feeding, either by dilution or substitution, significantly increased gizzard sizes in birds dissected on day 21 and day 35. Neither dilution nor substitution of feeds with whole wheat (400 g/kg) significantly affected the level of an Eimeria acervulina infection, as measured by daily and total faecal oocyst yields.

An experiment has been conducted to determine the effectiveness of growing broiler chickens when whole wheat grain has been included in the compound feed. The purpose of the research was to develop an appropriate scheme and dose for feeding whole wheat grain depending on the age of broilers, while observing the normative content of metabolic energy and nutrients in the diets, and to determine the economic effectiveness of rearing of broilers. To determine the effectiveness, data on live weight, growth rate, livability, uniformity of broiler population by live weight and variability of live weight of chickens have been studied. In the course of the work, the livability, average daily gain, feed conversion, homogeneity and variability coefficients, and the productivity index have been calculated. An increase in the live weight of broilers, as well as the rate of growth in pre-slaughter age when using whole grains in poultry diets, as well as a decrease in feed consumption per unit of live weight gain has been revealed. In conclusion, the economic effectiveness of broiler meat production has determined when whole grain has been included in diets. The use of whole wheat grain as an additive to the main diet in broiler feeding allowed to increase profits and increase the level of profitability. It has been found as a result of research that it is advisable to add whole wheat grain to the main diet for broilers at the age of 8–14 days in an amount of 5 % of the feed weight, at the age of 15–21 days – 15 %, at the age of 22–28 days – 20 %, at the age of 21–29 days – 30 % of grain without reducing the overall nutritional value of the diet.

Broiler chicken diets were diluted with three levels of whole wheat and two levels of crumbled wheat to determine how feeding whole grain and diluting feed with wheat would alter the performance of male and female broilers. Grit was not used. The amount of extra wheat added increased from 5% at 11 d of age to a maximum level of 30% at 31 d of age. Body weight at 41 d of age averaged 2.130 kg for pullets and 2.422 kg for cockerels and was unaffected by diluting with wheat, in whole or crumbled form. Total mortality and cause of mortality were similarly unaffected by dilution and form of wheat. The feed:gain ratio from 11 to 41 d of age was increased significantly for cockerels from 1.75 at zero dilution to 1.84 at maximum dilution. Dilution did not affect the feed conversion of pullets and form did not influence the feed conversion of either sex. Dilution of broiler rations may be profitable because of the limited effect on bird performance. Pelleting all the wheat in poultry rations is unnecessary because bird performance is unaffected by feeding up to 30% whole grain in the finisher diets.

The main aim of the present study was to investigate the changes in the relative growth of digestive organs of broilers as influenced by whole wheat feeding and age of birds. The secondary aim was to examine the effects of whole wheat feeding on broiler performance over a 5-week feeding period. Diets containing ground wheat and whole wheat (100 and 200 g/kg whole wheat replacing ground wheat during 1–21 days and 22–35 days, respectively) were placed in 4 replicate pens (46 birds/pen) each. Throughout the 5-week trial, the birds offered feed containing wheat as whole grain grew slower (P < 0.05) and consumed less (P < 0.05) feed than those offered feed containing ground wheat. Feed-to-gain ratio was not influenced (P > 0.05) by the form of wheat during the first 2 weeks, but was significantly lowered (P < 0.05) by whole wheat feeding from 3 weeks onwards. Over the 5-week period, the feed-to-gain ratio of birds fed the whole-wheat diet was 7 points better (P < 0.05) than of those fed the ground wheat diet. Improved feed efficiency from Week 3 onwards coincided with significant increases (P < 0.05) in the relative weights of the gizzard in birds fed the whole-wheat diet. Whole-wheat inclusion had no effect (P > 0.05) on the relative weights of crop, proventriculus, and pancreas or on the relative weight and length of the small intestine. The relative weights of storage sections of the gastrointestinal tract (crop, proventriculus, and gizzard) steadily declined during the 5-week period. The relative weights of pancreas and liver increased to Day 14 and decreased thereafter. The relative weights of intestinal segments were maximal during Weeks 1 and 2 of life, and declined rapidly with age. In general, the growth of different segments of the small intestine (duodenum, jejunum, and ileum) followed a similar pattern. The intestinal mass, measured as g tissue/cm tissue, steadily increased over the trial period, indicating that, although the relative size of the intestine declines with age, this decline is compensated by increased intestinal mass to support the nutrient supply function to the demand tissues.
