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.

Grower Diet

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.

Dietary Treatments

80, Olympic laying hens that had been in lay for 20 weeks were randomly allocated to 5 dietary  treatments and fed over a 10 week period. the birds were individually caged thus there were 16 replicates per treatment. The dietary treatment contained expeller pressed thevetia cake which had undergone anaerobiosis. The cake replaced soybean meal in the ratio of 0:1000, 25:75, 50:50, 75:25 and 100:0 dietary treatments significantly decreased (P<0.05) feed intake, egg production, feed efficiency and egg weight. The treatment however had no effect (P>0.05) on weight gain, mortality and egg quality parameters. Egg production and average egg weight was however not affected by replacement up to 50:50 substitution ratio (P>0.05). Nitrogen and fat retention decreased (P<0.05) with increasing thevetia cake concentration, while fibre was not affected. It was concluded that fermented expeller pressed thevetia cake can replace up to 50% of the soybean in layers' diet

Four unrelated pure strains of White Leghorns including a grandparent strain from industry and 12 two-strain, 24 three-strain, 24 four-strain and 12 F2 strain crosses produced contemporaneously were used to examine the role of dominance and epistasis in heterosis. A control strain and a commercial strain were also included. For egg weight, the heterosis observed closely approximated that expected due to dominance alone. For sexual maturity and body weight, dominance was the major component of heterosis, but epistasis made a significant contribution — additive by additive (A × A) genetic effects for sexual maturity and 140-d body weight, and parental epistasis for mature body weight. Both dominance and epistasis played a significant role in heterosis for egg production traits. A × A, dominance by dominance (D × D) and additive by dominance (A × D) epistasis were all important for hen-housed egg production and hen-housed egg yield. For hen-day rate of egg production, A × A epistasis was significant only early in the laying year (to 273 d), A × D and D × D were significant to 385 d and in the full year (to 497 d); however, none (A × A, A × D and D × D) was significant near the end of lay (386–497 d). Overall heterosis estimates for full year egg production measured as hen-housed egg production to 497 d or hen-day rate from housing to 497 d clearly showed that on average two-strain crosses were superior to three-strain crosses which were superior to four-strain crosses which in turn exceeded the F2 crosses. Nevertheless, several three-strain crosses had performance for egg production that was equal to or better than the two-strain cross with the highest egg production. Thus, in commerce, where the level of egg production is of great economic importance, the testing and use of a specific three-way cross combination will usually result in a better commercial product.

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.

The present study was to evaluate the impact of rapeseed meal (RSM), canola meal (CM), and their mixture substitute for soybean meal on performance of lactating sows and their offspring. In total, 16 Yorkshire×Landrace sows with initial BW 258.87±5.36 kg were used in this trial. The experimental period lasted 30 days. The sows were allotted to one of four dietary treatments (4 sows per treatment): 1) corn-soybean meal (SBM) basal diets; 2) basal diets containing 8% RSM; 3) basal diets containing 8% CM; 4) basal diets containing RSM (4%) and CM (4%) mixture (RSCM). Sows fed with RSM and RSCM diets had a higher (P less than 0.05) body weight loss than sows fed SBM diet. The parity, litter number, piglet survival rate, weaning pig number, backfat, ADFI and estrus interval were not influenced by dietary treatments (P greater than 0.05). The ADG of piglets from sows fed SBM was higher (P less than 0.05) than sows fed RSM at 1 week. After farrowing, the apparent total tract digestibility (ATTD) of dry matter in sows fed with SBM diet was higher (P less than 0.05) than the RSCM group. The ATTD of energy in SBM and CM treatments was higher (P less than 0.05) than that in RSM and RSCM treatments. On the weaning day, the ATTD of nitrogen and energy in SBM treatment was highest (P less than 0.05) than other treatments. In conclusion, inclusion of 8% rapeseed meal, canola meal, and their mixture substitute for soybean meal had negative effects on reproductive performance of lactating sows and their offspring.

The One

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.

This experiment was carried out to evaluate performance index and economic efficiency of broiler chicks fed diets containing dried blood rumen content mixtures (DBRCM) as a replacement for roasted soybean meal (RSBM). A total of 225 unsexed day-old broiler chicks (SASSO C44) were randomly allocated to five dietary treatments in a completely randomized design. Each treatment was replicated thrice with 15 birds per replicate. The experimental diets were formulated to contain 100% RSBM+0%DBRCM (T1), 80%RSBM+ 20% DBRCM (T2), 60% RSBM + 40% DBRCM (T3), 40% RSBM + 60% DBRCM(T4) and 20% RSBM+ 80% DBRCM (T5) based on a control ration contained 30% roasted soybean meal. The result showed that there was no statistical difference (P≥0.05) in performance index during the experimental period. The mean mortality was not influenced (P≥0.05) across the treatment groups. Birds fed T1 had the highest (P<0.05) and T5 the lowest (P<0.05) feed cost per kilogram feed. Feed cost per unit gain (Kg) was the highest (P<0.05) for T1 and the lowest (P<0.05) for T4 and T5. Total feed cost of the birds fed T1 was higher than those of the birds fed T5 diet. The highest (P<0.05) economic efficiency was observed for birds fed on T4 and T5. Based on this result, it could be concluded that 80% DBRCM can replace roasted soybean meal to achieve the highest economic efficiency, without affecting the performance index of broiler chicken.
