Diets containing 1.4, 2.5, and 3.5 per cent calcium were fed to pigs in two experiments to observe the effect on performance of calcium level in diets containing animal protein supplements. Rate of liveweight gain and efficiency of food conversion were depressed as the level of calcium increased. There was also a trend towards a decrease in the lean content of the ham with increased calcium intake. Dry matter and organic matter digestibility of the diets were depressed as calcium intake increased, but no apparent effect on nitrogen retention was detected. There was no indication of parakeratosis in any of the animals.

Wheat based diets containing 10, 20, or 30 per cent of meat meal or meat and bone meal were fed at a daily rate of 3.5 per cent of liveweight to Large White pigs in the 40-160 lb liveweight range. Dry matter and organic matter digestibility and nitrogen retention were determined on pigs fed the meat and bone meal diets. Increasing the inclusion level of both meat meal and meat and bone meal from 10 to 20 per cent significantly increased the lean content of the ham and tended to improve daily gain and feed conversion. Including meat and bone meal at 30 per cent of the diet resulted in a significant depression of growth rate and feed conversion efficiency between 40 and 160 lb liveweight. Dry matter and organic matter digestibility of the diets containing meat and bone meal decreased as the level of meal increased. Nitrogen retention appeared to be greatest at the 20 per cent level.

An experiment was conducted with 50 male, Friesian calves from 2 to 11 weeks of age. There were two basal diets, one containing meat meal and the other containing meat meal and urea as protein supplements to concentrate diets. The diets were fed with and without the addition of 5 per cent dried molasses. The addition of molasses to the diets increased the feed intake of both diets by 11 to 16 per cent. This resulted in increased weight gains of calves and increased nitrogen retention. The digestibility of dry matter and nitrogen was not affected.

This is the third in a series of reports on the growth, feed consumption and digestibility responses of growing pigs (50 to 110 pounds in weight) involved in a 2 × 2 × 2 × 2 factorial study of 0 vs. 10 per cent wheat bran, meal vs. pellets, 0 vs. 33 p.p.m. mixed antibiotics and plant versus animal-plant-origin protein supplements. The antibiotic mixture contained penicillin, streptomycin and chlortetracycline in the ratio 5:15:10.The growth and feed consumption response to antibiotics was generally favourable (P = <.05), but the greatest effects were observed on meal-type rations devoid of both animal protein and bran. In some cases antibiotics promoted more efficient conversion of feed dry matter into weight gains but usually the increased gains were due to increased feed intakes. The possibility of enhanced B-vitamin supply or utilization is discussed.Antibiotics effected an increase in energy digestibility but had relatively little effect on digestibility of protein. As with gains and feed intake responses the most marked energy digestibility effects occurred with meal rations that were bran-free and animal protein-free. Thus energy digestibility increases and feed intake increases largely accounted for the increased gains on these diets.The failure of antibiotics to effect as good responses in pelleted as in meal rations, or in the presence of bran or with animal protein, is discussed in relation to the matter of encouraging maximum feed intake and particularly with reference to ingesta behaviour and characteristics in various parts of the gastrointestinal tract.

ABSTRACTGrowth and carcass traits were measured in pigs grown from 25 to 90 kg live weight on barley stored and prepared in different ways. Some of the barley was prepared in the conventional manner by drying to a moisture concentration of 140g/kg before hammer-milling. The remainder of the barley was rolled after treating batches, containing 140, 180 and 240 g moisture per kg, with propionic acid. A total of 128 pigs was used at three centres.There were no differences between the centres and no differences in the performance and carcass measurements of pigs given acid-treated and rolled, or untreated and milled barley, despite differences in physical form between the rolled and milled samples. When the intake of dry matter was equalized there was no apparent effect on the pigs of acid treatment of barley containing different amounts of moisture.

Six male Landrace x Large White pigs (25 kg liveweight) were fitted with T-shape cannulae in the terminal ileum. The pigs were fed 1.2 kg dry matter per day containing 4.5 g threonine/kg of diet from continuous belt feeders. The apparent digestibility of dry matter (DM) to the terminal ileum was 0.91, 0.87, 0.85, 0.81, 0.80 and 0.75 for pigs given diets containing milk, fish meal, soybean meal, meat meal, sunflower meal and cotton seed meal respectively. The apparent digestibility of nitrogen (N) to the terminal ileum was 0.87, 0.87, 0.86, 0.86, 0.81 and 0.74 for pigs given diets containing milk, fish meal, soybean meal, sunflower meal, meat meal and cottonseed meal, respectively. The true digestibility of threonine to the terminal ileum was 0.96, 0.95, 0.90, 0.87, 0.80 and 0.66 for the diets containing milk, fish meal, sunflower meal, soybean meal, meat meal and cottonseed meal, respectively.

A series of experiments measured the effect of amino acid, copper, and vitamin B supplementation of 80 : 20 wheat--meat meal or wheat-meat and bone meal diets for Large White pigs during the growth phase between 18 and 45 kg liveweight. Diets were fed under a restricted feeding system. The addition of l-lysine to the diet increased nitrogen retention, liveweight gain, feed conversion efficiency, and lean content of the ham in experiment 1, and increased liveweight gain and feed conversion efficiency in experiment 2. No response to a lower level of l-lysine was obtained in a third experiment. There was no apparent effect of supplementary dl-methionine, either alone, or in combination with 1-lysine. A 21-fold increase in liver copper levels occurred in pigs supplemented with 250 p.p.m. copper, but no apparent effect on liveweight gain, feed conversion efficiency, or lean in the ham was detected. There was no apparent effect of a supplement containing riboflavin, pantothenic acid, and nicotinic acid on liveweight gain, feed conversion efficiency, or lean content of the ham.

Buckwheat (Fagopyrum esculentum) was evaluated alone or with 25, 50, 75 or 100% replacement by wheat (W) or barley (B) in 16% protein diets fed to 72 crossbred pigs from 20 to 60 kg liveweight. Pigs were randomly alloted two per pen, within sex, and housed in confinement on partially slatted concrete floors. Daily feed consumption (1.89–2.27 kg/day), average daily gain (0.66–0.72 kg/day) and feed/gain (2.79–3.18) did not differ significantly (P < 0.05) between treatments. At 50% replacement of the buckwheat (BW) more feed (P < 0.05) was consumed (2.22 kg/day) than at 25 or 100% replacement levels (1.99 and 1.92 kg/day, respectively). More DE was consumed per kilogram of gain (DE/gain) (P < 0.05) by wheat-fed pigs than by barley-fed pigs (40.0 vs. 38.2 MJ DE/kg, respectively). The 50% substitution of either grain (42.1 MJ/kg) resulted in more DE/gain (P < 0.05) than observed on the BW only diet (37.1 MJ/kg). Two 4 × 4 latin square designs, with eight pigs initially weighing 40 kg, were used for determination of digestibility of dry matter (DM), crude protein (CP) and gross energy (GE) in BW, W or B individually and in blends of BW and either W or B. Coefficients of digestibility for CP were 72.7%, 81.6% and 65.5% and for GE were 65.4%, 80.2% and 71.1% in BW, W and B, respectively. Blends of BW and W had digestibility coefficients for DM, CP and GE between the values determined for the grains individually but those determined for mixtures of BW and B were lower than expected based on coefficients determined for the grains individually. Buckwheat used contained 12% CP, 0.68% lysine, 12.3% acid detergent fiber on as fed basis and 9.6% digestible protein and 11.98 MJ of DE per kilogram dry matter. Key words: Buckwheat, pigs, digestibility, growth, mono-cereal diets

The effect of removal of soluble nutrients from soybean meal (SBM) and meat meal (MM) on in situ disappearance of dry matter (DMD) and nitrogen (ND) was measured. All feeds were rinsed with pH 6 buffer (R) without or with subsequent extraction with buffer at pH 5 (5) or pH 7 (7). Feeds were incubated in the rumen of heifers fed diets containing 20 or 80% concentrate (20%C and 80%C, respectively). Ruminal pH was higher (P < 0.05) in heifers fed the 20%C diet than in animals receiving the 80%C ration, while ruminal ammonia concentration tended to be greater with the 80%C diet. In situ DMD and ND were linearly related to incubation time (P < 0.01) with little indication of a quadratic effect of time. In situ ND of feeds extracted at pH 7 was greater (P < 0.05) than ND of feeds extracted at pH 5, but no interaction of diet and extraction pH or feed and extraction pH was apparent. Hence, altered protein solubility due to varied ruminal pH would not appear to be responsible for differences in ND with the different diets. In situ DMD and ND of both feedstuffs were greater (P < 0.01) with the 20%C than the 80%C diet. Hence, differences in microbial types or activities rather than chemical characteristics of the substrate are probably responsible for greater proetein loss with the lower concentrate diet. Key words: In situ, dry matter disappearance, nitrogen disappearance, soybean meal, meat meal

SUMMARYFeeding trials were carried out at different times of the year to determine the optimum crude protein requirements of weaner and growing pigs, using principally the locally available ingredients. The animals used were 96 weaners and 113 growing pigs of the Large White and Landrace breeds of average initial weights of about 9 kg and 41 kg respectively. Test diets contained protein levels ranging from 12% to 24% on a dry-matter basis, and the pigs were mostly group-fed ad libitum except for one trial. Average daily gains, efficiency of feed utilization, apparent nitrogen retention and digestibility, and feed cost per kg of body gain were measured. In a humid tropical environment, such as Ibadan, the optimum crude protein requirement for weaner pigs from 9 kg to 34 kg live weight is between 22 % and 24 % of dry matter, while that for the fattening pigs from 41 kg to 82 kg live weight is between 18% and 21% of dry matter.
