A total of 1536 SCWL pullets of two commercial genotypes (768 of each) were fed soybean meal (SM), Tower or Candle rapeseed meal (RSM) during either the growing and laying period or both. RSM can replace a major portion (74%) of the soybean meal of starter and grower diets without adversely affecting mortality or feed consumption. Differences were observed between the two genotypes for all traits measured during the laying period, except for mortality. Switching the birds from a SM grower diet to a 15% RSM layer diet resulted in a significant (P < 0.05) increase in mortality. In general, the feeding of Tower RSM during both the growing and laying period resulted in heavier birds, earlier sexual maturity, higher egg production and improved feed efficiency compared to when diets containing Candle RSM were fed.

The performance of four commercial meat-type parental genotypes and their progeny was significantly different when they were fed breeder diets supplemented with Brassica napus 'Tower' or B. campestris 'Candle' rapeseed meals (RSM), or both, compared with a commonly used commercial breeder diet supplemented with soybean meal (SM). The egg production of birds on the RSM diets was equal to or better than that of birds fed the diets supplemented with SM, and, although eggs from birds on RSM diets were significantly smaller in size than those from birds fed SM diets, the number of eggs weighing 47 g or more was not significantly different. There were also significantly more broiler chicks from breeders on the RSM diets than from those on SM diets. There were significant differences among genotypes for several performance traits, but mortality, age at sexual maturity, feed efficiency, specific gravity of eggs, fertility and hatchability were not affected by the dietary treatments. Although mortality among male broiler progeny from parent stocks on RSM breeder diets was higher than normal, monetary returns per bird started was greater than that from progeny of breeders on SM diets. Key words: Rapeseed meal, soybean meal, meat chicken breeders, canola

Ad Libitum

Five swine experiments were conducted to evaluate rapeseed meal (RSM) of low glucosinolate content (Brassica napus L. cv. Bronowski). Two experiments involved 0, 25, 50, 75 and 100% substitution of either Bronowski meal or regular (B. campestris) meal for soybean meal or fishmeal used in the control diet. One experiment compared ad libitum-fed and partially restricted pigs. Another experiment involved digestibility studies, and the final one involved methionine and lysine supplementation. As the dietary levels of either Bronowski or regular RSM increased in the ration, protein digestion coefficients decreased from 79 and 80% to 76 and 78%, respectively, and energy coefficients decreased from 82% to 79 and 78%, respectively. The protein and energy digestibility coefficients for Bronowski RSM were estimated to be 68 and 59%; for regular RSM, 65 and 54%. With barley–wheat–RSM diets, pigs responded to 0.1% methionine, but not to lysine (P > 0.05). Pigs fed ad libitum consumed more Bronowski than regular RSM diet and performed as well as pigs fed soybean meal diets.

Continuous Feeding

Thirty dairy heifer calves were reared from birth to calving on rations containing 0, 6.8 or 13.7% rapeseed meal in substitution for soybean meal. The level of rapeseed meal did not significantly (P > 0.05) affect feed intake, weight gain or feed efficiency of heifers up to breeding weight (330–340 kg). The level of rapeseed meal did not significantly (P > 0.05) affect reproduction or milk production during the first lactation. However, there may have been a trend for lower conception rate and milk fat production during first lactation with the higher level of rapeseed meal.

Four groups of 48 laying hens (Gallus domesticus), midway in their laying cycle were fed diets containing graded levels (0.00%, 1.5%, 2.5% and 3.5%) of dietary Nutrafos 3 for 56 days. The completely randomized experimental arrangement was designed to evaluate the responses of the caged layers to the inclusive levels of the additive under humid tropical conditions. The dietary additive produced statistically significant (P< 0.01) improvements in the rate of egg production of the hens. Significant increases (P< 0.01) in feed consumption and improvements in feed efficiency (P < 0.01) were also observed. Haugh unit was significantly (P < 0.05) depressed by dietary Nutrafos 3, especially at the highest level of inclusion. There was no treatment effect on egg size as well as some major anatomical characteristics. The best overall performance was achieved at the 3.5% level of dietary inclusion in contrast to the proprietary recommendation of 2.5%.

Six hundred and seventy-two 1-day-old male broiler chicks of two strains were used to assess the effects of diet and color of diet on feed consumption. Isocaloric isonitrogenous diets that contained soybean meal (control), rapeseed meal, or ground rapeseed were fed in either colored or noncolored form. During the starter period the birds were given a choice of two diets in various combinations whereas during the grower period no choice was available. In the starter period there were no significant effects of color or diet combinations on total feed consumption. Coloring one diet of a pair, however, tended to increase the difference in consumption between the two by reducing the intake of the colored diet. The one exception to this was the diet pair containing ground rapeseed, which was not affected when one diet was colored. The control diet was preferred, followed by the diets containing rapeseed meal and ground rapeseed, respectively, when a choice was available. When no choice of diet was available in the grower period the only significant effect of color was to increase consumption of the ground rapeseed-containing diet. Weight gain in both periods was highest on the control diet followed by the diets containing rapeseed meal and ground rapeseed, respectively.

Abstract The aim of the study was to determine the usefulness of two protein concentrates composed of rapeseed meal and new cultivars of narrow-leaved and yellow lupine, peas in laying hen diets and their influence on birds’ performance and egg characteristics. The experiment was conducted with 180 layers kept in individual cages. The birds were randomly assigned to three treatments, with 60 hens in each and during the period of 17 weeks, they were fed diets: I - containing soybean meal as a protein source, II - containing protein concentrates composed of mixture of lupines, peas (19.48% of diet) and rapeseed meal, III - containing protein concentrates composed of a mixture of lupines and peas (27.68% of diet). The body weight, laying rate, egg weight, feed intake and feed conversion ratio (FCR) and egg characteristics were registered. After 9 weeks of experiment, a decrease of laying rate was recorded in treatment III. The mean value of laying rate for 17 weeks amounted to 82.7 (I), 82.5 (II) and 75.9% (III) (P<0.01). The egg weight was diversified already after 4 weeks of egg production and averaged 57.9 (I), 55.9 (II) and 54.9 g (III) (P<0.05). Feed intake amounted to 108 (I), 111 (II) and 104 g per hen/day (III), and FCR was 2.05, 3.17 and 2.23 kg/kg egg weight, respectively. As to egg characteristics, increases of white index (P<0.05), Haugh unit score and yolk colour in treatment III were observed but egg shell thickness was found significantly reduced. In conclusion, the use of about 27.68% of legume seed in laying hen diet affected negatively performance results but about 19.48% of these seeds and 8% rapeseed meal in diets could be accepted as a soybean meal substitute.

Foram avaliadas duas fontes de proteína, farelo de soja e soja integral extrusada, e 5 níveis de substituição (0, 25, 50, 75 e 100%) do milho pelo triticale, em rações para suínos em crescimento e terminação. Considerando-se o período total, ganho de peso e consumo diários de ração foram menores (P0,05) entre os níveis. Conclui-se que, corrigindo-se a energia, a substituição total do milho por triticale é viável. Abstract Rations containing two sources of proteins, soybean meal and extruded soy seeds, and 5 levels (0, 25, 50, 75 and 100 %) of substitution of the corn by triticale were evaluated in experiments performed to study the growing and finishing behavior of swine’s. Extruded soy been seeds’ diet showed the lower average gain weight and feed consumption (p < 0.05) in the total period of the experiment. Corn substitution at 0 and 50% displayed a higher slaughter weight in spite of the fact that the feed efficiency was not different between these levels (p < 0.05). It may be concluded that by introducing a correction in the diets’ energy values, the substitution of maize by triticale is viable.

Grower Diet

The use of high protein wheat as the main component of a grower diet for laying strain pullets from seven weeks of age to point-of-lap was investigated. This diet was shown to have an inadequate lysine content for maximum growth rate, and was probably also deficient in arginine. Birds receiving this diet were restricted in their growth rate, and consequently their sexual maturity was delayed. Subsequent egg production was increased sufficiently to offset this delay, and an advantage of this diet was found to be a reduced food intake during the growing period

The post-molting performance of 360 female Japanese quails was assessed using five molting methods including feed restriction along with supplementation of dietary levels of aluminum sulfate (AlSO4) and zinc oxide (ZnO) with two concentrations of 0.15% and 0.3%. None of the parameters studied were positively influenced by a single molting method. Body weight gain and feed efficiency were positively affected by higher concentration of ZnO while feed consumption was positively influenced by higher concentration of AlSO4. Similarly high feed efficiency was attributed to higher concentrations of both ZnO and AlSO4. On other hand body weight gain and feed efficiency were negatively influenced by 0.15% ZnO while egg production was worst by 0.15% AlSO4. As each of the molting method had different influence on the tested parameters and none of them could apply individually with perspective of better performance therefore the combinational use of molting methods is recommended according to the focused parameter
