Growth Trial

Two starter pig trials were conducted to evaluate a new type of soybean (SB), AC Proteus, containing higher levels of protein than conventional cultivars. In the first trial, AC Proteus was included at 0, 4, 8, 12, 16, or 20% of the isonitrogenous and isoenergetic soybean meal based diets and fed to starter pigs from 10 to 25 kg In the second trial, AC Proteus was included at 0, 3.5, 7, 10.5 or 14% of the diet, or a conventional soybean, Baron, was included at 0, 4.4, 8.8, 13.3 or 17.7% of the diet on an isoenergetic and isonitrogenous basis.Amino acid levels in AC Proteus on an air-dry basis were higher than those in the conventional soybean, Baron. In the first trial, inclusion of AC Proteus at higher levels appeared to decrease feed intake and rate of gain, although this appeared to be due to lower levels of amino acids in the diets and overheating of the roasted soybean. In the second trial, inclusion of either type of soybean had no effect on feed intake, rate of gain, or feed conversion efficiency. At higher levels of inclusion of AC Proteus, feed intake was reduced slightly.AC Proteus appears to be an excellent source of protein and energy in starter pig diets and gives equivalent growth responses compared with soybean meal or conventional soybean. Care must be taken to optimize heat processing of AC Proteus. Key words: High protein soybean, starter pigs, growth trial

There is an interest in replacing soybean meal with locally produced ingredients in livestock feeds. Narbon vetch is resistant to unfavorable climatic and soil conditions, common pests, and has a favorable nutritional profile. The effect of substitution of soybean meal with 0% (V0), 5% (V5), 10% (V10), and 20% (V20) inclusion of Narbon vetch on growth curve parameters, daily body weight gain (DBWG), daily feed intake (DFI), feed conversion efficiency (FCE), and residual feed intake (RFI) was investigated in 47 Duroc × Iberian barrows in 16 periods (a total of 125 d). DFI and DBWG were reduced (p < 0.05) up to four weeks after introduction of the novel feed in V20 and V10. Small, mostly nonsignificant differences existed between treatments in FCE and RFI. However, because of accumulative small differences in feed efficiency between the four diets, pigs in V0 reached the highest BW, and pigs in V20 reached the lowest BW on a similar feed intake. Economic implications of Narbon vetch inclusion depend on the extra amount of feed required and associated feed costs, and on the costs of additional days on-farm required to reach a given slaughter weight.

Four experiments were conducted with rats to investigate the effects of autoclaving and alkali treatment on the growth-promoting ability of pigeonpea meal. In the fifth experiment, the effect of autoclaving pigeonpea meal was evaluated with pigs. With rats, there was a quadratic response (P < 0.05) in growth and feed conversion ratio to autoclaving pigeonpea seed for 15 min at 100-140�C, with maximum response occurring at c. 124�C. However, growth rate was still lower and feed conversion ratio higher than those of rats fed soybean meal (P < 0.05). Imbibing pigeonpea seed in alkali and subsequently drying it to original weight did not reduce tannin content but did reduce the trypsin-inhibitor activity from 10.3 to 5.1 units mg-1. Although both alkali treatment and autoclaving of the alkali-treated seed improved the growth and feed conversion ratios of rats, these treatments did not overcome the differences in protein quality between the pigeonpea and soybean meal diets. Autoclaving pigeonpea seed for 15 min at 110, 124 and 140�C reduced the trypsin-inhibitor activity of the meals from 11.2 to 0.7 units mg-'. Compared to pigs fed on unheated pigeonpea meal, pigs given autoclaved meal had higher (P < 0.05) growth rates and improved feed conversion ratios. These improved growth responses were similar to those produced by soybean meal.

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.

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.

Dietary Protein Level

Forty-eight pigs, 16 each of boars, barrows, and gilts, were allotted at an average age of 41 days to two treatment groups based on dietary protein level, either 18% protein throughout or 16% protein in the growing period (start to 50 kg) and 13% protein in the finishing period (50–90 kg). Feed intake during the growing period was influenced by sex with boars eating less (P < 0.05) than barrows. No significant differences in feed intake were observed for the overall experiment but the trend established in the growing period still existed. In the overall experiment sex did not influence rate of gain, which averaged 0.72 kg/day. Higher dietary protein level improved (P < 0.01) gain in comparison with the lower levels. A significant interaction existed between sex and protein, boars responding more to high protein than barrows, and gilts being intermediate. Feed conversion was influenced (P < 0.05) by sex and protein level, boars being superior to barrows or gilts and pigs fed the higher protein diet (3.16 kg feed per kg gain) superior to those fed the lower protein diet (3.36 kg feed per kg gain). Barrows dressed 79.6% and gilts 79.3% both higher (P < 0.01) than boars, which dressed 75.9%. Boars had a grade index of 102.6 and gilts 101.4, both of which were higher (P < 0.01) than barrows with 97.9. Other carcass measurements generally ranked the sexes in order of superiority as boars, gilts, and barrows. Boar carcasses had more muscle and less fat (P < 0.01) than barrows, gilts being intermediate. Dietary protein level did not significantly influence carcass composition. Six muscles were analyzed for protein, fat, and ash. No significant differences between sexes were found, but higher protein level increased (P < 0.05) the percentage protein in the longissimus dorsi muscle. Fatty acid analyses of backfat showed no significant differences except in linoleic and linolenic acids, for which boars and gilts had higher percentages than barrows. Detectable sexual odor on cooking was judged to be present in 56% of boar carcasses. If procedures to eliminate sexual odor can be developed, boars offer promise as market animals, particularly if they are fed relatively high protein diets.

Wool Growth

The wool growth responses to changes in feed intake are related to the changes produced in body weight. The relation is expressed by the equation W = Ei-kG, where W = wool growth rate, i = feed intake rate, G = rate of body weight change, and E and k are constants. The ratio of E to k in sheep of different productive efficiency was found to be constant.

A feeding trial to evaluate the per­formance of finishing steers fed main­ly on sugarcane tops with or without cotton­seed and molasses was conducted in Niono, Mali during the dry season. 96 Zebu steers, weighing between 220 and 250kg were randomly alloted to four groups of twenty-four steers each The performance parameters compared were: feed intake, rate of gain, feed conver­sion and carcass characteristics. The diffe­rences observed for feed intake, rate of gain and feed conversion appear to be more related to roughage level rather than source. There were no nutritional disorders. Results from this initial feeding trial indicate that a sugarcane — derived feedstaffs can be used to constitute a major component of finish­ing steer rations particularly in the dry areas of the tropics where sugarcane tops are regarded as wastes.

Eighty crossbred pigs (28.7 ± 3.9 kg BW) were assigned to one of five dietary treatments in a factorial design experiment (sex × treatment). The control diet was formulated using barley and soybean meal, while four experimental diets were formulated with either toasted or non-toasted canola meal replacing either half or all of the soybean meal in the test diets. The total glucosinolate content of the non-toasted meal was more than 15-fold higher than the to asted meal (1.01 vs. 15.58 µmol g-1). The principal glucosinolates in the non-toasted meal were 3-butenyl (3.05 µmol g-1), 2-OH-3-butenyl (5.47 µmol g-1) and 4-OH-3-methylindoyl (4.68 µmol g-1). Digestibility coefficients for dry matter, crude protein, and gross energy were significantly (P < 0.05) lower for the toasted and non-toasted canola meal diets compared with the soybean meal diet. There were no significant differences (P > 0.05) in digestibility coefficients between the two canola meals. Digestibility coefficients were higher (P < 0.05) for pigs fed the diets in which canola meal supplied only 50% of the supplementary protein compared with diets in which 100% of the supplementary protein was supplied by canola meal. Pigs fed toasted canola meal had similar weight gain, feed intake and feed conversion (P > 0.05) as pigs fed soybean meal while pigs fed non-toasted canola meal had lower weight gain and feed intake (P < 0.05) than pigs fed soybean meal. Feed conversion was unaffected by dietary treatment (P > 0.05). There were no significant effects (P < 0.05) due to diet on any carcass trait. The overall results of this experiment indicate that omitting the desolventization/toasting procedure from the process involved in the production of canola meal did not result in an improvement in the performance of pigs fed diets containing canola meal. Key words: Pigs, canola meal, performance, digestibility, carcass, toasting

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.

Heat Requirement

Climatic and housing conditions in the fattening of pigs are discussed in relation to heat requirements and feeding level. Increase in feeding level will allow pigs to meet their thermal heat requirement at lower ambient temperatures. From fattening trials reported in the literature, mean feed intake, rate of gain, feed conversion, backfat thickness and lean meat to fat ratio have been computed at temperatures of 5, 10, 15, 20 and 25 °C. Feed intake was lowest at 25 °C. Rate of gain was maximal and feed conversion (ratio feed intake: liveweight gain) was minimal at about 20 °C. At computed similar intakes of feed, rate of gain decreased with 15 g/°C below 20 °C. Backfat thickness was as a mean decreased in the cold, as was lean meat to fat ratio. Optimum feeding level for feed conversion may be increased to above 80% of ad libitum intake.
