Five experiments were conducted to evaluate the influence of rye level, ergot and penicillin on the utilization of rye by growing chicks. The effects of the following factors and/or treatments, respectively, were studied: increasing levels of rye replacing wheat in the diets for starting and finishing broiler chicks; ergot, pelleting and penicillin supplementation of rye diets; the cleaning of the beaks or vents of rye-fed chicks; and increasing levels of penicillin in rye diets containing different levels and types of protein supplements for Leghorn chicks. The results indicate that a diet containing 15% rye depressed the appetite and growth of young broiler chicks. Levels of rye higher than 15% in the diet depressed not only growth but also the efficiency of feed utilization in all chicks. The level of ergot in excess of three times that present in the uncleaned rye diet (0.11%) had no influence on chick performance. Wet excreta were produced by rye-fed but not by wheat-fed chicks. There was no relationship, however, between chick performance, and excreta "wetness," beak impaction and vent blockage. An improvement in chick performance was elicited by pelleting or penicillin supplementation of rye diets; the magnitude of the chick response to the latter treatment appeared to be influenced by the type and level of the dietary protein supplement. A dose-response study demonstrated that the maximum effective response to penicillin supplementation occurred when a rye–meat meal diet contained penicillin at or in excess of 160 mg/kg of diet; the corresponding maximum improvements in weight gain and the efficiency of feed utilization were 46 and 18%, respectively.

The response of broiler chicks fed rye with dietary pentosanase supplementation was examined with respect to rye variety, area of production, and maturity at harvest. There were significant differences among varieties in the absence of enzyme addition and significant differences (variety × enzyme, P < 0.01) in the magnitude of the chick growth response to dietary pentosanase (exp. 1). Kodiak and Cougar rye gave greater enzyme-induced growth response than did Gazelle rye, with Musketeer rye and an unknown sample displaying intermediate values. Experiment 2 gave similar results; both Kodiak and Cougar rye in chick diets gave a larger response to dietary pentosanase than did Musketeer rye (P > 0.05). Determination of soluble carbohydrates, as well as extract viscosity, indicated that Kodiak rye had higher extract viscosity, higher extractable pentosan content, and a lower arabinose-to-xylose ratio; however, these results were not consistent with Cougar rye. Differing production location of a single variety (Musketeer, exp. 3) or maturity at harvest (exp. 4) indicated no significant effect on the nutritive value of rye attributable to location or maturity with or without enzyme supplementation, nor was there an effect on the magnitude of enzyme response. In rye harvested at different stages of maturity there was, however, a nonsignificant linear depression in chick growth with rye harvested at higher moisture levels.

summaryGrowth and visceral organ weights of male guinea fowl (Numida meleagris) given different levels of oxytetracycline have been studied in two experiments. In the first experiment 0, 5·0, 10·0, 15·0 and 20·0 mg oxytetracycline per kg diet were given to male guinea fowl from day 1 to 12 weeks. Body weight showed significant (P < 0·05) increases with incremental levels of the antibiotic up to 10 mg/kg diet. No further increases in growth were recorded with supplementation above this level. There were no treatment effects on the gizzard, lungs and male reproductive organs. Only the heart, liver and intestine weights were significantly (P < 0·05) affected by the treatment, and then only at the highest (20 mg/kg) of the inclusion rates examined. A second experiment was conducted to find out if the growth response obtained with 10 mg/kg oxytetracycline could be produced with a smaller dose. This was achieved at 6·6 mg/kg.
