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.

Two experiments were conducted to determine the utilization of ileal digestible isoleucine by growing pigs. In the first, the apparent ileal digestibility of amino acids in cottonseed meal, lupin-seed meal and soya-bean meal was determined in pigs fitted with‘T‘-shaped cannulas. In the second, three isoleucine-deficient diets were formulated to 0.23 g ileal digestible isoleucine/MJ digestible energy (DE) with the three protein concentrates contributing the only source of isoleucine in sucrose-based diets. An additional three diets were formulated with supplements of isoleucine to confirm that isoleucine was limiting in the first three diets. The growth performance and retention of isoleucine by pigs given the six diets over the 20–45 kg growth phase were then determined. The apparent ileal digestibility of isoleucine in the three protein concentrates (proportion of total) was: cottonseed meal 0.68, lupin-seed meal 0.86, soya-bean meal 0.86. There were no significant differences (P > 0.05) in growth rates (g/d) and crude protein deposition rates (g/d) of the pigs given the three diets formulated to 0.23 g ileal digestible isoleucine/MJ DE: cottonseed meal 590, 84; lupin-seed meal 613, 87; soya-bean meal 594, 91 (SEM 13.0, 2.9) respectively. The response of pigs to the addition of isoleucine confirmed that isoleucine was limiting in these diets. The proportion of ileal digestible isoleucine retained by pigs given the cottonseed meal (0.65) was slightly lower than that retained by pigs given soya-bean meal (0.73; P < 0.05). These results indicate that values for the ileal digestibility of isoleucine in protein concentrates more closely reflect the proportion of isoleucine that can be utilized by the pig than occurs for other amino acids such as lysine, threonine and methionine.

Six pigs (25 kg initial weight) were fitted with T cannulas in the terminal ileum. Each pig was fed a nitrogen (N) free diet or one of eight diets containing increasing amounts of threonine from milk (four diets) or cottonseed meal (four diets). The flow of endogenous nitrogen from the terminal ileum was 1.1 g/kg dry matter DM intake in the pigs given the nitrogen-free diet and 0.9 g/kg DM intake when estimated by extrapolation in the pigs given the milk or cottonseed meal diet. There were no significant differences in the flow of individual endogenous amino acids from the terminal ileum when measured in pigs given a nitrogen-free diet or when extrapolated from data for pigs given diets containing milk or cottonseed meal. The flow of endogenous threonine from the terminal ileum was between 0.39 and 0.45 g/kg DM intake as estimated in pigs given diets with similar threonine intakes from cottonseed meal or milk and the nitrogen-free diet.

The ileal digestibility of tryptophan for growing pigs was determined for cottonseed, meat-and-bone and soya-bean meals. Tryptophan in the food and digesta was measured by two analytical procedures (NaOH hydrolysis and colorimetric estimation (method 1) and LiOH hydrolysis and HPLC determination (method 2)). The results were respectively: cottonseed meal 0.46, 0.81; meat-and-bone meal 0.55, 0.65; soya-bean meal 0.74, 0.90. In the first experiment the values for method 1 were shown to be inapplicable to pigs. In a second experiment three tryptophan-deficient diets (005 g ileal digestible tryptophan/MJ digestible energy (DE)) were formulated using values from method 2 for cottonseed meal, meat-and-bone meal plus L-tryptophan and soya-bean meal respectively as the only sources of tryptophan in the diets. This experiment was terminated after 28 d as overall growth performance of the pigs was very low. A third experiment was conducted in a similar manner to Expt 2 except that the diets were formulated to 0.065g ileal digestible tryptophan/MJ DE and growth responses and tryptophan retention were assessed over the 20–45 kg growth phase. Growth rates (g.d) of the pigs given the three diets were significantly different (P < 0.01): cottonseed meal 393, meat-and-bone meal plus L-tryptophan 531, soya-bean meal 437 (SED 39.0). Tryptophan retention (as a proportion of ileal digestible tryptophan intake) was significantly different (P < 0.05): cottonseed meal 0.51, meat-and-bone meal plus L-tryptophan 0.49, soya-bean meal 0.41. These results indicate (1) that the colorimetric technique for assessing tryptophan was inapplicable and (2) that ileal digestible values for tryptophan were not suitable for formulating diets containing heat-processed proteins, possibly due to absorption of some of the tryptophan in a form that was non-utilizable, and/or to underestimation of total tryptophan in the protein concentrates.

Abstract To evaluate the effect of cottonseed meal (CSM) on growth performance, plasma gossypol and complete blood cell (CBC) counts in growing pigs, 40 gilts (Exp 1) and 24 boars (Exp 2), 63 day of age (19.85±0.43 kg), were randomly allotted to 1 of 4 and 3 treatments with 2 replicates/treatments, respectively. Treatments for Exp 1 during phase 1–3 (14 d/phase) were a nutrient adequate control diet (NRC, 2012) without CSM (0% gossypol), and increasing levels of CSM was added to produce diets containing 0.01%, 0.02% and 0.04% gossypol to form treatments 2 to 4, respectively. For Exp 2, treatments were the same as those in the gilt trail, except 0.01% gossypol treatment was eliminated. All pigs were fed a common diet without CSM in phase 4 (14 d). Whole blood was obtained from two close-to-average pen-BW pigs repeatedly at each phase to determine CBC in Exp 1 and plasma gossypol in Exp 1 and 2. Data were analyzed using the Mixed procedures of SAS (Cary, NC). ADG did not significantly differ between treatments in phase 1&2 (P &gt; 0.05). In phase 3, ADG decreased linearly and quadratic (P &lt; 0.05) with increasing level of CSM in gilts and boars, respectively, while ADFI did not differ. Neutrophil concentration was higher while mean corpuscular volume (MCV) was lower in gilts fed CSM on d 42 than those fed control regardless level of inclusion, whereas after 14 d of CSM withdrawal, neutrophil level was similar to control and MCV remained low (Treatment*day, P &lt; 0.01). Plasma gossypol increased with increasing level of CSM in both gilts and boars during phase 1–3, and was still higher than control after pigs were fed a common diet for 14 d (P &lt; 0.05). In conclusion, cottonseed meal derived gossypol impairs growth performance, and increase plasma gossypol in gilts and boars.

The nutritive value of locally produced cottonseed meal, incorporated at a level of 10 per cent in wheat based diets, was compared with meat and bone meal and soybean meal for growing pigs. The effect of adding synthetic lysine to the cottonseed meal diet was also observed. The diets were fed at restricted rates and pig performance was assessed over the 18 to 45 kg, 45 to 73 kg, and 18 to 73 kg growth phases. Cottonseed meal was of similar nutritive value to meat and bone meal and the addition of lysine increased growth and feed conversion during the 18 to 45 kg growth phase. Soybean meal produced similar gains to the cottonseed meal plus lysine diet during the 18 to 45 kg range, but greater gains than the other three diets over the 18 to 73 kg range. Carcase quality was similar for all four diets. With cottonseed meal there was an increase in the ratio of saturated to unsaturated fatty acids in the backfat of the pigs due to cyclopropene fatty acids in the residual oil in the meal. The metabolizable energy values of the diets were approximately 96.7 per cent of the digestible energy values and there was a significant correlation between them (r = 0.94). The correlation between digestible energy values estimated by the methods (gross energy in the feed X dry matter digestibility) and (gross energy in feed - gross energy in faeces/dry matter intake) was significant (r = 0.92).

An experiment was conducted to determine the utilization of ileal digestible methionine by growing pigs. Three methionine-deficient diets (0·09 g ileal digestible methionine/MJ digestible energy (DE)) were formulated using cottonseed meal, meat-and-bone meal and soya-bean meal respectively as the only source of methionine in the diet. An additional three diets were formulated with supplements of methionine to confirm that methionine was limiting in the first three diets. The growth performance and retention of methionine by pigs given the six diets over the 20–45 kg growth phase was then determined. Growth rates (g/d) of pigs given the three diets formulated to 0·09 g ileal digestible methionine/MJ DE were significantly different (P < 0·01): cottonseed meal 411, meat-and-bone meal 442, soya-bean meal 496 (SED 24·6). The response of pigs to the addition of methionine confirmed that methionine was limiting in these diets. Crude protein (N × 6·25) deposited by the pigs (g/d) was significantly higher (P < 0·05) for those given soya-bean meat (61) and meat-and-bone meal (57) relative io cottonseed meal (47; SED 3·3). The proportion of ileal digestible methionine retained by pigs given the three protein concentrates was: cottonseed meal 0·39, meat-and-bone meal 0·45, soya-bean meal 0·47 (SED 0·019). These results indicate that values for the ileal digestibility of methionine in protein concentrates do not reflect the proportion of methionine that can be utilized by the pig. It appears that, with heat-processed meals, a considerable proportion of the methionine is absorbed in a form(s) that is (are) inefficiently utilized.
