This study was conducted to determine the performance and carcass characteristics of growing-finishing pigs fed diets containing graded levels of canaryseed. Sixty-four crossbred pigs (Pig Improvement Canada Ltd) weighing 34.4 ± 2.8 kg were assigned on the basis of sex, weight and litter to one of five dietary treatments in a factorial (5 treatments × 2 sexes) arrangement. A barley and soybean meal diet served as the control. The remaining pigs were fed diets in which approximately 25, 50, 75 or 100% of the barley was replaced by canaryseed (cv. Elias). There was a linear (P = 0.01) decrease in dry matter digestibility with increasing level of canaryseed. In contrast, crude protein digestibility showed a linear increase (P = 0.01) with increasing level of canaryseed. Gross energy digestibility of the diets did not differ (P > 0.05). Over the entire experimental period (34.4 to 107.8 kg), there was a quadratic (P = 0.01) response for weight gain. The 25% canaryseed diet supported the highest growth rate and pigs fed the 100% canaryseed diet had the lowest gain. Feed intake and feed conversion were unaffected (P > 0.05) by level of canaryseed. There were no differences (P > 0.05) in carcass weight, carcass value index, estimated lean yield, loin fat depth or loin lean depth as a result of canaryseed inclusion. However, there was a quadratic (P = 0.02) response for dressing percentage with increasing level of canaryseed. The overall results of this experiment provide a favorable indication that canaryseed can be successfully fed to growing-finishing pigs without dramatically affecting pig performance or carcass characteristics. Therefore, in the future, the swine industry may provide an alternative to the caged bird market as an outlet for growers of canary seed to market their product.

The objective of this experiment was to determine the effects of feeding graded levels of Linpro (a 50:50 combination of extruded full-fat flax seed and peas) on pig performance and carcass traits, particularly the fatty acid composition of backfat. Eighty crossbred pigs (Camborough 15 Line female × Canabred sire, Pig Improvement Canada Ltd., Airdrie, AB) weighing an average of 22.7 ± 2.2 kg were assigned on the basis of sex, weight and litter to one of five dietary treatments in a 5 × 2 factorial arrangement (treatment × sex). The experimental diets were based on barley and soybean meal and contained 0, 7.5, 15, 22.5 or 30% Linpro during the growing period (22.7–69.7 kg) and 0, 6, 12, 18 or 24% Linpro during the finishing period (69.7–111.1 kg). Digestibility coefficients for dry matter were not significantly affected by incorporation of Linpro in the diet. Digestibility coefficients for crude protein (P = 0.01) and gross energy (P = 0.04) exhibited a cubic effect due to Linpro incorporation with the highest digestibility coefficients observed for pigs fed 7.5% Linpro. Over the entire experimental period (22.7–111.1 kg), daily gain was affected both linearly (P = 0.02) and quadratically (P = 0.04) by Linpro inclusion. The most rapid gains were obtained by pigs fed 7.5% Linpro (6% in finisher), while pigs fed 30% Linpro (24% in finisher) gained weight the slowest. Feed intake was not significantly affected by Linpro inclusion, while feed conversion exhibited a quadratic effect (P = 0.02) with pigs fed the highest and lowest levels o f Linpro showing the poorest feed conversion. Linpro inclusion, had no significant effects on carcass traits including slaughter weight, carcass weight, dressing percent, carcass value index, lean yield, loin fat or loin lean. Inclusion of 30% Linpro (24% in finisher) significantly (P < 0.05) increased the levels of linolenic acid in backfat and this increase could provide significant health benefits for consumers of pork. Linpro would appear to be an acceptable alternative to soybean meal as a protein supplement for use in growing-finishing swine diets and can be incorporated at levels as high as 22.5% in the grower period and 18% in the finisher period without detrimental affects on pig performance.

Abstract A total of 860 finishing pigs (PIC C48/L42×327; initially 66.2 kg BW) were used in a 76-d experiment to evaluate the effects of removing corn DDGS from diets at increasing intervals before harvest. Diets contained 40% DDGS prior to the experiment, 0 or 35% DDGS during the experiment from approximately 66 to 82 kg and 0 or 30% DDGS until the completion of the trial. Pen served as the experimental unit, and there were 7 replicate pens/treatment with 23 to 25 pigs/pen. Pens were blocked by BW and allotted to 1 of 5 dietary treatments, differentiated by the number of days prior to slaughter that diets containing DDGS were withdrawn and replaced with corn-soybean meal-based diets. Withdrawal times were 76, 42, 27, 15, or 0 d (no withdrawal) before harvest. Linear and quadratic response to withdrawal time was evaluated using PROC GLIMMIX. For the overall period (d -76 to 0), as time of DDGS withdrawal increased, ADG and final BW also increased (linear, P < 0.018) and G:F improved (quadratic, P = 0.019). Average daily feed intake quadratically decreased (P = 0.030) with increasing withdrawal time. There was a linear increase (P = 0.010) in HCW, with a marginally significant increase in carcass yield (linear, P = 0.094) with increasing DDGS withdrawal time. Loin depth and lean percentage did not demonstrate any evidence for treatment differences (P > 0.132). Backfat was linearly increased (P = 0.030) with increasing DDGS withdrawal time. Lastly, iodine value (IV) of belly fat was increased (linear, P = 0.001) with increased feeding duration of DDGS. In conclusion, removing pigs from diets containing DDGS for longer periods before slaughter increased ADG and improved G:F, resulting in increased HCW. Belly fat IV was decreased as the length of DDGS withdrawal increased, with the highest IV resulting from pigs that consumed DDGS for the entire experimental period.

Feeding Diets

The objective of this study was to compare a high-fat oat recently developed at the University of Saskatchewan with regular oat as energy sources for use in diets fed to growing-finishing pigs. Seventy crossbred pigs (Pig Improvement Canada Ltd, Acme, AB) weighing an average of 27.5 ± 2.6 kg were assigned on the basis of sex, weight and litter to one of five dietary treatments in a factorial design experiment. The main effects tested included oat type (normal and high fat), level of oat inclusion (0, 25 and 50%) and sex of pig (barrows and gilts). Digestibility coefficients for dry matter (P = 0.002), crude protein (P = 0.001) and gross energy (P = 0.004) were significantly higher for pigs fed high-fat oat compared with normal oat. Pigs fed the high-fat oat also gained weight significantly faster (P = 0.01) and with increased efficiency (P = 0.01) compared with pigs fed diets containing normal oat. Oat level did not affect pig performance (P > 0.05). Neither type of oat nor level of inclusion had any significant (P > 0.05) effects on any carcass trait including dressing percent, carcass value index, lean yield, loin fat or loin lean. In conclusion, feeding diets containing a recently developed high-fat oat to pigs improved growth rate and efficiency of feed conversion compared with feeding diets containing normal-fat oat. Nutrient digestibility also improved with no negative effects on carcass quality. High-fat oat is an attractive alternative to normal oat as an energy source for growing-finishing pigs and can be fed at higher levels than are currently recommended for normal oat without hindering pig performance.

This experiment was conducted to determine the effect of graded levels of number 1 wheat screenings on performance, nutrient digestibility and carcass traits when fed to growing-finishing pigs. Forty crossbred pigs (Camborough 15 Line female × Canabred sire) weighing an average of 19.7 ± 2.8 kg were assigned to one of five dietary treatments in a 5 × 2 factorial design experiment. The main effects tested included level of wheat screenings and sex of pig (barrows and gilts). The levels of inclusion were 0, 18, 36, 54 and 72% in the grower diet and 0, 20.5, 41, 61.5 and 82% in the finisher diet. Screenings were added largely at the expense of barley. A botanical analysis was preformed and it indicated that the screenings contained approximately 88.5% whole or cracked wheat with the most prevalent weed seeds being wild buckwheat (6.7%), canola seed (2.8%) and cleavers (0.96%). There was a linear (P = 0.001) increase in the digestibility of dry matter, crude protein and gross energy with increased incorporation of wheat screenings in the diet. Over the entire experimental period (19.7–105.1 kg), there was no change in growth rate due to feeding wheat screenings, but feed intake declined in a linear (P = 0.044) fashion while feed conversion improved linearly (P = 0.014) as the inclusion level of screenings increased. There were no sex effects on pig performance. Dietary inclusion of wheat screenings had no significant effects on any carcass traits including dressing percent, carcass value index, lean yield, loin fat or loin lean. The carcass value index for gilts was higher than that of barrows (P = 0.038). The overall results of this experiment indicate that number 1 wheat screenings can be successfully uti lized as an energy source for use in growing-finishing diets and can be fed at levels as high as 72% for growing pigs and 82% for finishing pigs with no negative effects on pig performance or carcass quality. However, should the level of weed seeds increase or the type of weed seeds contaminating the screenings change appreciably from those reported here, then it may be necessary to reduce the incorporation level of screenings in the diet.

One hundred and twenty-four feeder pigs, representing two breed groups (Hampshire × Yorkshire and Yorkshire) were used in three experiments to compare the live performance and carcass characteristics of boars, barrows and gilts fed, from 25 to 92 kg, a 16% protein, barley–soybean meal diet or diets based on a utility grade, soft wheat (Triticum aestivum cv. Pitic 62) with 0, 7½ and 15% field peas (Pisum sativum cv. Century) to provide total protein levels of 13, 14 or 15%. Under conditions of adequate nutrition, boars were superior to barrows in efficiency of feed conversion and estimates of carcass leanness, while gilts were intermediate in feed conversion and equivalent to boars in carcass indices. The amount and composition of the diet consumed had a greater effect upon the relative performance of boars and, to a lesser extent, of gilts than was observed with barrows. In addition, the dressing percentage was consistently lower with boars than with barrows or gilts. Sexual odor or taint was not noticeably present in the carcasses at the packing plant, although there was a tendency for meat from boars on restricted feeding to have a higher moisture and darker lean than that present in carcasses from barrows and gilts. The results also suggested that satisfactory performance of growing–finishing pigs could be achieved with diets based on Pitic 62 wheat using field peas as the sole source of supplementary protein.

A concise and factual abstract This study aims to find out the influence of the use of banana peels in pellet rations to improve the performance of local male rabbits (Lepus nigricollis). The study used 20 local male rabbits that were maintained from 5 to 12 weeks old. The study used Randomized Group Design with 4 treatments and 5 repeats. The treatments in this study are: Rabbit feed that did not contain banana peels (R0), Rabbit feed that contained 5% banana peels (R1), Rabbit feed that contained 10% banana peel (R2), and Rabbit feed that contained 15% banana peel (R3). The results showed no noticeable difference (P>0.05) in the treatment of rations against the ingenuity of dry matter digestibility, energy digestibility, protein digestibility, protein consumption, consumption of dry materials, and Feed Conversion Ratio (FCR). Rabbits who get R1 ration treatment produce the final weight and the weight gain was significantly different (P<0.05) to R0 and R3 treatment, and not significantly different (P>0.05) on R2 treatment. R1 ration consumption is the highest (P<0.05) compared to R0, R2, and R3 treatments. The effect of ration treatment on carcass variables shows results significantly different (P<0.05).

The purpose of the present study was to assess the effect of diets for market pigs with 20% inclusion of lupine seeds, cv. Amiga, on the performance, health status, carcass characteristics, fatty acids (FA) profile of meat lipids and nutritional and sensory parameters of meat. Another purpose was to increase the nutritional value of a cereal-lupine diet (E1) by supplementation with lysine, methionine, threonine (E2) or fat (E3) and to perform a comparison with control diets containing animal protein (C1) or soy (C2). The experiments were performed on 50 pigs (50% males, 50% females) with initial body weights of 35.6 &plusmn; 2.2 kg, fed isonitrogenic and isoenergetic diets partly <i>ad libitum</i> for 90 days. Feed intake was not adversely affected by lupine inclusion. The daily body weight gain (BWG) was significantly higher (<i>P</i> < 0.05) in group E3 in comparison with the cereal-lupine diet group (E1) and the other groups by 12.6 to 15.9% during the initial 30 days of experiment. The highest BWG (0.88 &plusmn; 0.07 kg/kg) during the entire experimental period was obtained with the fat containing diet (E3); that was non-significantly higher by 2.3 to 10.0% in comparison with the other diets. The feed conversion rate was reduced in groups E3 and E2 (2.55 and 2.58 kg/kg BWG) by 3.1 to 7.6% in comparison with groups C1, C2 and E1. No adverse effect of the lupine containing diet was observed on the carcass characteristics or the nutritional quality of the meat. Optimum content of linolenic acid in lupine seeds had a favourable effect on n-6/n-3 polyunsaturated FA ratio in meat lipids of group E3 in comparison with groups C1 and E1 (<i>P</i> < 0.05). By sensory meat analysis, significantly better characteristics were found for texture, juiciness (<i>P</i> < 0.01, <i>P</i> < 0.05) and taste in E3 in comparison with groups C1, C2 and E1. The obtained results indicate that animal and soy protein may be replaced with lupine, tested in the present study, in case a diet is supplemented with amino acids and fat.

The objective of the study was to evaluate the effects of expanded diets on growth performance, meat quality, and carcass characteristics in finishing pigs. A total of 80 finishing pigs [(Landrace × Yorkshire) × Duroc] were randomly allotted to two dietary treatments: 1) unexpanded corn-soybean meal diets; 2) expanded corn-soybean meal diets. Each treatment consisted of ten replicate pens with four pigs (2 gilts and 2 barrows) per pen. There were no differences in daily feed intake and daily gain throughout the experiment (P less than 0.05). However, expanded diets decreased feed conversion ratio compared with unexpanded diets (P less than 0.05). Expanded diets had no effect on carcass characteristics and meat quality with the exception of increased sensory evaluation (color) of meat compared with unexpanded diets (P less than 0.05). In conclusion, expanded diets can improve feed conversion ratio but have no effect on daily gain and daily feed intake and sensory evaluation of meat color.

Zinc Bacitracin

SUMMARYThree experiments were carried out to evaluate zinc bacitracin as compared with penicillin, as a feed supplement for bacon pigs. The first experiment compared pig performance on a control diet with performance on the control diet supplemented with penicillin, 5 g./ton, or with zinc bacitracin, 10 g./ton. Experiment 2 compared the control diet with penicillin at 10 g./ton and zinc bacitracin at 10 g./ton with pigs housed in a different piggery. Experiment 3 compared the control diet with penicillin at 10 g./ton and zinc bacitracin at two levels, 10 g./ton and 5 g./ton. In none of the experiments was there any significant response to penicillin in terms of rate of gain, feed conversion efficiency or carcass composition. In the first experiment there was a small but significant improvement in rate of gain up to 100 lb. live-weight and for the whole experimental period by the pigs receiving 10 g./ton of zinc bacitracin. There was no significant response in feed conversion efficiency or carcass measurements. In the other two experiments there was no response to zinc bacitracin. The implications of the results are discussed.

SUMMARYNinety pigs were divided into two replicated groups, randomly allotted to three treatments: (1) control, (2) 2 g of diethylstilbestrol (DES) and 2 g of methyltestosterone (MT) per ton and (3) 2 g DES + 2 g MT + 10 g tylosin per ton. Rate of gain was not affected by treatment; however, pigs fed the treated rations consumed less feed and were more efficient in feed conversion. Carcasses of pigs fed DES + MT or DES + MT + tylosin had significantly less backfat and a slightly higher percentage of ham and loin, and of lean cuts.
