At an average weight of 83 kg and age of 163 days, 32 gilts were allotted to four dietary treatments, 0, 4 or 8% solvent-extracted rapeseed meal (RM) throughout the experiment, or 8% RM fed for the first 100 days of gestation followed by 0% RM. The RM, of Brassica campestris origin and containing 2.40 g oxazolidinethione and 2.60 g isothiocyanates per kg meal, was added in substitution for isonitrogenous levels of soybean meal (SM) for two reproductive cycles. Feeding RM did not significantly influence daily gain or feed conversion efficiency from 83 kg to the first breeding or during the two gestation periods. No significant differences were noted in number of services to conception, length of gestation, number of pigs born or born alive, number of pigs weaned, litter birth weights or weaning weight, or pig birth weights or weaning weights. There was a trend toward reduced litter size from gilts and sows fed the diets containing RM. Changing the diet from 8% RM to 0% RM after 100 days of gestation did not influence reproductive performance. Lacombe × Yorkshire sows gained more from 83 kg live weight to the first breeding, had higher breeding weight in both gestation periods, and increased pig weaning weight for the second lactation period compared with Yorkshire sows. The latter sows had higher individual pig birth weights for the first reproductive cycle than the crossbred sows. The results indicate that a level of 8% commercial solvent-extracted RM of the type fed may be acceptable as a substitute for an isonitrogenous level of SM in the diets of gestating and lactating gilts and sows.

An experiment was conducted during the late fall and winter months with 96 Yorkshire barrows and gilts to study the effects on pig performance of feeding corn-soybean meal (SBM) and lysine-HCl (0.1%) supplemented corn-SBM-Tower rapeseed meal (RSM) and corn-SBM-Candle RSM diets, in the form of mash (corn was medium-ground) and steam pellets. Average daily gain (ADG), feed intake, efficiency of feed conversion (feed to gain ratio, F/G) and carcass backfat thickness were measured in pigs reared from 23 kg to 91 kg liveweight. The energy level in the RSM diets was not adjusted to equal that in the corn-SBM diet. Pigs fed Tower RSM had a lower (P < 0.01) feed intake and backfat thickness and pigs fed Candle RSM had a lower (P < 0.01) ADG and feed intake and higher (P < 0.01) F/G compared to the pigs fed SBM. The pigs fed corn-SBM-Tower RSM had a higher (P < 0.01) ADG and feed intake and lower (P < 0.01) F/G ratio than those fed Candle RSM diets. Steam pelleting of the corn-SBM and corn-SBM-RSM diets improved ADG, feed intake and F/G of the pigs, with the effects being greatest for the RSM diets.

An experiment was conducted during the spring and summer months with 96 Yorkshire barrows and gilts, to study the effects of feeding corn-soybean meal (SBM), corn-SBM-Tower rapeseed (RSM) and corn-SBM-Candle RSM diets, in the form of mash and steam-processed pellets on average daily gain (ADG), efficiency of feed conversion (feed to gain ratio) F/G), average daily feed intake and carcass backfat thickness of pigs reared from 23 kg to 91 kg liveweight. Tower RSM or Candle RSM at the 15% level in corn-SBM based diets did not result in any adverse effects on ADG, feed intake or backfat thickness, but did increase F/G (P < 0.05). There were no differences in F/G between pigs fed Tower RSM and Candle RSM diets. Steam pelleting enhanced ADG (P < 0.01) and F/G (P < 0.05) across all three diets, but did not affect feed intake or backfat thickness. Barrows had higher (P < 0.01) ADG and backfat thickness than gilts, but did not differ in feed intake or F/G.

Growth And Reproduction

An experiment with 32 crossbred gilts averaging 10 kg at allotment was designed to evaluate prepress-solvent extracted rapeseed meal (RSM) of Brassica campestris origin as a partial replacement for soybean meal (SBM) in diets of sows during growth or growth and reproduction when the sows were retained for three reproductive cycles. Four treatments were involved: (1) sows fed SBM throughout; (2) gilts fed 6% RSM to 90 kg and SBM for the remainder of the experiment; (3) gilts fed 6% RSM to immediately prior to first mating and SBM for the remainder of the experiment; (4) sows fed 6% RSM throughout. A second experiment with 16 mature Yorkshire sows evaluated the same RSM for one reproductive cycle only as a partial replacement for SBM when introduced into the diet immediately prior to breeding. During the growing period to 90 kg, daily feed intake, gain, and feed conversion did not differ significantly for gilts fed 0 or 6% dietary rapeseed meal, daily gain averaging 0.68 kg. Digestible energy, metabolizable energy, digestible nitrogen, and nitrogen retention coefficients were not influenced by level of dietary RSM or by period (15 or 45 kg) at which digestibility studies were conducted. Gestation length, litter size, and weight at birth and weaning were not influenced by dietary treatment in either experiment. Thyroid weights and ratio of thyroid weight to body weight of representative 2-wk-old female pigs did not differ significantly between treatments. In the first experiment, there was an average disposal of 23% of the sows per reproductive cycle because of failure to breed, failure to conceive, and other causes but these removals did not appear to be associated with treatment. The overall results suggest that up to 6% RSM of the type fed is not detrimental to sow performance when the RSM is fed during growth, throughout growth and reproduction, or when introduced suddenly at the time of breeding.

AbstractThe aim of this study was to assess the effect of weaning weight and post-weaning diet on the performance of weaned pigs. In experiment 1, 30 litters with more than 10 pigs born alive per litter were selected. At 11 days of age, pigs of average weight for the litter were removed from 15 litters so that eight pigs remained per sow. These litters were given access to creep food (16·5 MJ digestible energy (DE) per kg and 18·7 g/kg lysine). The remaining litters were left complete and were not given creep food. Pigs were weaned at 28 days of age and pairs of pigs (a male and a female littermate of similar weight) were formed from each litter (no. = 54 pairs). Pairs were blocked on the basis of litter origin and weight and assigned at random to one of the following treatments: (1) 10 kg starter diet (16·1 MJ DE per kg and 17·4 g/kg lysine) followed by link diet (15·3 MJ DE per kg and 15·0 g/kg lysine) to 27 days (high dietary regimen; HDR); or (2) 4 kg starter diet, 10 kg link diet and weaner diet to 27 days (low dietary regimen; LDR). Thereafter pigs were given common diets to slaughter at about 95·6 kg live weight. On experiment 2, four pigs (two light and two heavy) were taken from each of 32 litters (no. = 128 pigs; age = 22 days), blocked on sex, litter origin, and weaning weight and within weight category individually assigned at random to two dietary treatments: (1) high density diet (16·1 MJ DE per kg and 17·4 g/kg lysine); and (2) low density diet (15·1 MJ DE per kg and 15·7 g/kg lysine). The duration of the experiment was 26 days. In experiment 1, reducing litter size and creep feeding increased weaning weight by 0·6 kg (P 0·05). This weight advantage at weaning was lost by day 14 post weaning (P > 0·05). From day 0 to day 27 post weaning daily gain was 472 and 427 g/day (s.e.12·8; P 0·05) and food conversion efficiency was 1·26 and 1·36 g/g (s.e. 0·026; P 0·05) for HDR and LDR, respectively. In experiment 2, weaning weight was 7·1 and 5·8 kg (s.e. 0·08; P 0·01) and pig weight at day 26 post weaning was 17·5 and 15·4 kg (s.e.0·23; P 0·01) for heavy and light weight categories, respectively. In the period from day 0 to 26, food intake was 440 and 396 g/day (s.e. 8·0; P 0·01) and daily gain was 389 and 355 g/day (s.e. 8·0; P < i 0·01) for heavy and light weight categories, respectively. Weaning weight was found to be a good determinant of weight at day 26 when terms for litter origin were included (R2 = 0·67; P 0·001 for the high density diet and R2 = 0·77; P 0·001 for the low density diet). It is concluded that weaning weight can be increased by pre-weaning management but that this weight advantage is lost in the early post-weaning period. Where weaning weight was naturally higher the weight advantage was still evident at day 26 post weaning.

A 70-day feeding trial was conducted with thirty-six 7 weeks old weaned rabbits (mixed breed and sexes), with initial average live weight of 0.81kg to evaluate the nutritional effects of replacing maize at 0,25, and 50%with maize or corn gluten in rabbit diets. Maize gluten is fermented maize milling waste sun dried for three days. The diets were offered to the rabbits which were randomly divided into three (3) groups of 12 rabbits each and each group sub-divided into four (4) replicates of 3 rabbits each in a completely randomized experiment. There was a significant effect (P<0.05) of the treatments on the average daily feed intake of the rabbits as the levels of maize gluten increased. The average weight gain and feed conversion ratio were not significantly (P>0.05) affected by the dietary treatments, nevertheless, the FCR increased across the treatments. Graded levels of maize gluten had no significant (P>0.05) effect on carcass dressing percentage. The percent pelt decreased significantly (P<0.05) as level of maize gluten increased. Furthermore, liver and meat cooking loss percentage values showed significant differences (P<0.05) due to the graded levels of corn gluten fed. The sensory evaluation studies were not statistically affected (P>0.05).

Twenty-four sows (six littermate groups of four sows each) from 29 to 106 kg liveweight were fed either 0 or 8% solvent-extracted rapeseed meal, substituted on an isonitrogenous basis for soybean meal and wheat. The two groups were then subdivided to receive either 0 or 8% rapeseed meal in their diets through two complete reproductive cycles.Average daily gain of gilts fed rapeseed meal was lower throughout the growing period but was significantly depressed only from 90 to 106 kg liveweight. Number of services to conception, gestation weight gains, gestation length and lactation weight losses were not significantly influenced by dietary treatment. In the first reproductive cycle, sows fed rapeseed meal during the growing period farrowed only 0.2 pigs less per litter than those fed the diet containing soybean meal, but weaned 2.5 pigs less which resulted in a reduced litter weaning weight.During the second reproductive cycle, treatment during growth had no significant influence on performance of the sows or litters. Sows fed rapeseed meal during gestation and lactation performed as well during both reproductive cycles as those fed the soybean meal diet. The results indicate that levels of 8% rapeseed meal should not be fed to growing gilts that are to be saved for reproduction.

Seventy-two crossbred gilts were used in an experiment to evaluate low glucosinolate rapeseed meal (RSM), derived from the cultivar Tower, as a partial or complete replacement for soybean meal (SBM) in diets for gilts from 20 kg liveweight through two gestation and lactation periods. The supplementary protein sources for the three dietary treatments were: (1) SBM; (2) a 50:50 mixture (on an isonitrogenous basis) of SBM and Tower RSM: and (3) Tower RSM. The gilts were fed diets containing 17% protein from 20 to 60 kg, and diets containing 15% protein from 60 kg until the end of the second lactation. Fifty-one animals completed two reproductive cycles. There were no significant differences in litter size and weight at birth or weaning, sow weight changes in gestation or lactation, or gestation length in either the first or second parity. The results indicate that Tower RSM (containing 0.98 mg/g total glucosinolates) may be used as a partial or complete replacement for SBM in the diets of pregnant and lactating swine for at least two reproductive cycles with no apparent reduction in sow reproductive performance.

A feeding trial was conducted to determine the effect of varying dietary levels of protein on performance of Japanese quail chicks. Six iso-caloric (2953-3078 kcal/kg, ME) diets were formulated to contain crude protein (CP) at 18, 20, 22, 24, 26 and 28% levels, respectively. Each of the dietary treatment was replicated three times with sixty (60) quail chicks per replicate. A total of 1080 day-old unsexed quail chicks were used for the study and distributed using completely randomized design. The experiment lasted 42 days during which data were collected. Feed and water were provided ad libitum throughout the experimental period. Feed intake, weight gain, feed conversion ratio and protein intake differ significantly (P<0.05) due to dietary treatments. Final live weight and cost per gain were not significantly (P>0.05) different across dietary treatments. Age at first egg and average weight of eggs at point of lay differed significantly (P<0.05) across dietary treatments. The haematological parameters (Total protein, haemoglobin, albumen and red blood cell) were significantly (P<0.05) affected by the dietary protein levels. Carcass weight, dressing percentage, prime cuts and the weight of major organs expressed as percentage of the live weight were not significantly (P>0.05) affected by the dietary treatments. It was concluded that Japanese quail chicks required up to 26% level of dietary protein for optimum performance.

AbstractThe aim of the study was to assess the effect of fermented dried soybean (FSBM) and/or fermented rapeseed meal (FRSM) in diets for weaned piglets on production results, nutrient digestibility, gastrointestinal tract histology, and the composition of the gut microbiota. Piglets in the control group received standard diets with soybean meal. Animals in all experimental groups received diets in which a portion of the soybean meal was replaced: in group FR—8% FRSM; in group FR/FS—6% FRSM and 2% FSBM; in group FS/FR—2% FRSM and 6% FSBM and in group FS—8% FSBM. The use of 8% FRSM or 6% FRSM and 2% FSBM in the piglet diets had a positive effect on average daily gains. Piglets from the FR and FR/FS groups had the highest feed conversion rate. Group FS/FR and FS piglets had significantly lower mortality and lower incidence of diarrhoea. Piglets fed a diet with the fermented components, in particular with 8% FRSM or 6% FRSM and 2% FSBM, exhibited a positive effect on the microbiological composition and histology of intestines, which resulted in improved nutrient digestibility coefficients (ATTD and AID).

Sixteen blocks of eight littermate pigs were weaned at 3 weeks of age and each divided into four groups. Various levels of nutrition were applied to the pigs so that the four groups reached 20 kg. at 59, 68, 80 and 91 days of age, respectively.Only small differences were observed between groups in feed conversion ratio to 20 kg.; however, Group 4 required more feed per kg. gain than the three other groups.During the second period (20–90 kg.) the pigs in each group were divided into two sub-groups, which were on a high and a low plane of nutrition respectively. In both sub-groups the type of feeding before 20 kg. influenced the average daily gain and feed conversion ratio. The older the pigs were at 20 kg. the higher the daily gain and the lower the feed conversion ratio in the following period. There was an increase in daily feed intake with increased age at 20 kg. for pigs fed ad lib. during the second period.An increase in age at 20 kg. caused a significant decrease in thickness of backfat, a greater area of eye muscle and a smaller area of fat overlying muscle. For pigs fed ad lib. the area of eye muscle was significantly increased by a higher age at 20 kg. live-weight.
