Fifteen sheep were used in a trial which compared the feeding value of whole barley gain and cottonseed cake as supplements to a basal diet of leaves of fourwing saltbush (Atriplex canescens). Diet SB contained 700 g (air-dry matter) of saltbush alone, diet SB + BG contained 700 g SB with 400 g whole barley grain and diet SB + CS contained 700 g SB with 400 g cottonseed cake. The digestibility of the dry matter of diets SB (69%) and SB + CS (70%) were lower (p < 0.001) than of diet SB + BG (76%). Sheep offered SB alone daily lost 80g whereas those fed the other diets gained 11 g (SB + CS) or 17 g (SB + BG) per day. Daily water consumption of the sheep offered the three diets was similar (p > 0.05), but their water consumption was higher (p < 0.001) than that of sheep offered daily 700 g wheat straw and 200 g barley grain. The results indicate that, at the levels of feeding used, barley grain and cottonseed cake had similar value as supplements to fourwing saltbush harvested in summer. The addition of the supplement allowed the sheep to gain some live weight. However, the presence of saltbush leaves in the diet resulted in higher water intakes by the sheep.

Crossbred dairy does were fed a roughage diet (IVOMD 56%, N 2.27%) ad libitum, and supplemented with urea-molasses (3% W : W) (UM) at levels on an air dry basis of 1.5% or 3% of liveweight or an iso-energetic, iso-nitrogenous mixture of cottonseed meal and molasses (25 : 75 w : w) (CM). Eight does, four lower-producers and four higher-producers (1.9 and 2.5 kg/day respectively in week 7 of lactation) arranged in two Latin Squares, received each of the four diets for three weeks. Dry matter, digestible organic matter and N intakes were higher for high-producers and high levels of supplement but did not differ between nitrogen sources. Milk production was higher by high-producers; interactions were significant between level of supplement and production group and between level of supplement and N-source, with maximum production by high producers on high levels of CM. The main effects of level of supplement were only significant for production or composition. and total solids; N-source did not have significant effects on liveweight, milk production or composition. We conclude that does of moderate capacity for milk production, receiving a diet of two-thirds moderate quality roughage, one third urea-molasses, will not respond to increased level of supplementation or to replacement of urea with cottonseed meal.

Four lactating Holstein cows were used in a $4{\times}4$ Latin-square design to determine the effects of various levels of whole cottonseed (WCS) in diets on parameters including milk (yield and fat content), rumen fluid (pH, ammonia and TVFA) and blood (${\beta}$-carotene, vit. A, vit. E, urea, $NH_3$, Ca, P and Mg levels). Cows consumed 0, 1, 2 or 3 kg WCS per day. No significant differences were observed among the groups on analysed parameters except plasma vitamin E concentration. In addition, when the amount of cottonseed was increased, milk yield and milk fat content also tended to increase but this increase was not statistically significant. In conclusion, feeding of WCS up to 3 kg per day with ad libitum maize silage did not cause negative effects on milk yield, milk fat and blood vitamin levels in the short term in dairy cows.

Triglyceride compositions of cottonseed, soybean, sesame, perilla corn and rapeseed oils have been determined by a high performance liquid chromatographic analysis. An optimum condition was obtained by using a ALC/GPC 244 type, from Waters Association, Japan with $\mu$ Bondapak $C_{18}(1/4^{'}\times1^{'})$ column. A similar distribution pattern of triglycerides was found in cottonseed, soybean, sesame, rapeseed and corn oils. It was noted that $C_{40}$, $C_{42}$ and $C_{44}$ were the major components in these seed oils, except perilla oil. The results showed that contents $O_{40}-C_{48}$ triglyceride types in cottonseed, sesame and corn oil were within $2.23{\sim}41.24%$ and $C_{38}-C_{48}$ triglyceride types in soybean oil were within $3.01{\sim}10.02%$ and $C_{34}-C_{46}$ triglyceride types in rapeseed oil were within $2.38{\sim}28.68%$.

In this study, the immunomodulatory activity of oligopeptide (CP) derived from solid-state fermented cottonseed meal were investigated in immunosuppressed BALB/c mice models by treatment with cyclophosphamide (CY). Results indicated that oligopeptide increased the thymus and spleen indices of CY-treated mice. The count of plague forming cells (PFC) and the content of half serum hemolysis ($HC_{50}$) in immunosuppressive mice were restored to the normal level in CP-10 and CP-20 groups while the cytokines interleukin (IL)-2, IL-6, and tumor necrosis factor alpha (TNF-${\alpha}$) were increased significantly in CP-20 group. Similar increasing the immunoglobulin of IgG and IgM content in the serum of CP-10 group were also observed. These findings indicated that oligopeptide derived from solid-state fermented cottonseed meal had a strong immune-enhancing activity as well as a protective effect against immunosuppression induced by cyclophosphamide in mice.

This study was designed to examine the response of feeding early weaning diets without and with amino acids supplemented cottonseed meal on growth performance and digestibility of early weaned cow calves. Fifteen 14-21 days old cross bred cow calves were randomly allotted to three experimental diets. Diet A comprised of milk replacer and concentrate feed whereas two isocaloric and iso-nitrogenous early weaning diets viz., B and C were prepared without and with lysine and methionine supplemented cottonseed meal, respectively. These early weaning diets were used as substitute of milk replacer for calves. Calves were placed in individual cages and fed twice daily for a period of 60 days. Daily feed intake, feed refused and weekly weight gain was recorded. Two digestibility trials I and II were performed at 5th and 9th week of the experiment, respectively. During the digestibility trial I, calves were fed on ad libitum basis whereas in trial II, calves were fed at 90% of their voluntary DMI. Feed, orts and feces samples were collected, weighed daily, composited, subsampled and analysed for DM and CP. Results indicated that weight gain of calves was (p<0.05) higher on diets A (0.63 kg/d/calf) and C (0.64 kg/d/calf) compared to calves on diet B (0.57 kg/d/calf). Significantly (p<0.05) less daily DMI was observed on diet A (1.48 kg) compared to early weaning diets B (1.70 kg) and C (1.72 kg). The feed efficiency was (p<0.05) better on diet A (2.33) compared to diets B (2.95) and C (2.65). The economic efficiency was noticed to be better on diets B and C compared to diet A. In trial I, digestibility of DM and CP of diet A was (p<0.05) higher than diets B and C. Whereas in trial II, digestibility of DM and CP of diet A was (p<0.05) less than diets B and C. It was concluded that early weaning diet based on lysine and methionine supplemented cottonseed meal produced better weight gain and feed efficiency compared to non-supplemented cottonseed meal based diet.

Statistical optimization of the production medium was carried out in order to find an optimal medium composition in itaconic acid fermentation process. Itaconic acid utilized in the manufacture of various synthetic resins is a dicarboxylic acid biosynthesized by fungal cells of Aspergillus terreus in a branch of the TCA cycle via decarboxylation of cis-aconitate. Through OFAT (one factor at a time) experiments, six components (glucose, fructose, sucrose, soluble starch, soybean meal and cottonseed flour) were found to have significant effects on itaconic production among various carbon- and nitrogen-sources. Hence, using these six factors, interactive effects were investigated via fractional factorial design, showing that the initial concentrations of sucrose and cottonseed flour should be high for enhanced production of itaconic acid. Furthermore, through full factorial design (FFD) experiments, negative effects of $KH_2PO_4$ and $MgSO_4$ on itaconic acid biosynthesis were demonstrated, when excess amounts of the each component were initially added. Based on the FFD analysis, further statistical experiments were conducted along the steepest ascent path, followed by response surface method (RSM) in order to obtain optimal concentrations of the constituent nutrients. As a result, optimized concentrations of sucrose and cottonseed flour were found to be 90.4g/L and 53.8g/L respectively, with the corresponding production level of itaconic acid to be 4.36 g/L (about 7 fold higher productivity as compared to the previous production medium). From these experimental results, it was assumed that optimum ratio of the constituent carbon (sucrose) and nitrogen (cottonseed flour) sources was one of the most important factors for the enhanced production of itaconic acid.

In order to explore mycelial growth and fruiting body formation of Lyophyllum decates on different media, ten cultivation media by using cottonseed hull, sawdust, corn cob etc. as main components were designed for seven strains. The results showed that the mycelial colour of all strains are mainly snow-white, and the formula of media using corn cob as main materials was better than that using cottonseed hull and sawdust for mycelial growth, but no fruiting body was formed. The cottonseed hull medium with a small amount of sawdust, plant leaves, humus or fermented material and wheat was beneficial for fruiting formation. The incubation period for fruiting formation of strain 3001 was 108 days and the highest yield was-214.80 g/bag. Fructification of the strains tasted occurs successively in order of 3001, 1035, 1004 and 1013. It was concluded that different medium composition had significant effect on the mycelial growth and fruiting body formation.

The objective of this study was to investigate the effect of carbohydrate source and cottonseed meal level in the concentrate on feed intake, nutrient digestibility, rumen fermentation and microbial protein synthesis in swamp buffaloes. Four, 4-yr old rumen fistulated swamp buffaloes were randomly assigned to receive four dietary treatments according to a $2{\times}2$ factorial arrangement in a $4{\times}4$ Latin square design. Factor A was carbohydrate source; cassava chip (CC) and CC+rice bran at a ratio 3:1 (CR3:1), and factor B was level of cottonseed meal (CM); 109 g CP/kg (LCM) and 328 g CP/kg (HCM) in isonitrogenous diets (490 g CP/kg). Buffaloes received urea-treated rice straw ad libitum and supplemented with 5 g concentrate/kg BW. It was found that carbohydrate source did not affect feed intake, nutrient intake, digested nutrients, nutrient digestibility, ammonia nitrogen concentration, fungi and bacterial populations, or microbial protein synthesis (p>0.05). Ruminal pH at 6 h after feeding and the population of protozoa at 4 h after feeding were higher when buffalo were fed with CC than in the CR3:1 treatment (p<0.05). Buffalo fed with HCM had a lower roughage intake, nutrient intake, population of total viable and cellulolytic bacteria and microbial nitrogen supply than the LCM fed group (p<0.05). However, nutrient digestibility, ruminal pH, ammonia concentration, population of protozoa and fungi, and efficiency of microbial protein synthesis were not affected by cottonseed meal levels (p>0.05). Based on this experiment, concentrate with a low level of cottonseed meal could be fed with cassava chips as an energy source in swamp buffalo receiving rice straw.

Objective: This study aimed to determine and compare the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of amino acids (AA) in soybean meal (SBM), cottonseed meal (CSM), and low-gossypol cottonseed meal (LCSM) fed to broiler chickens and laying hens. Methods: Three semi-purified diets containing the identical crude protein concentration at 20% were formulated to contain SBM, CSM, or LCSM as the sole source of N. A N-free diet was also formulated to estimate the basal ileal endogenous losses of AA for broilers and hens. A total of 300 male Ross 308 chicks at one-day-old and 144 Hy-Line Brown laying hens at 30-week-old with initial egg production rate of 88.3%±1.0% were randomly allocated into 1 of 4 dietary treatments, respectively. Results: CSM and LCSM showed more Arg and Cys+Met while less Lys, Ile, Leu, and Thr relative to SBM. Significant interactions existed between species and experimental diets for AID (except for Arg, Asp, Glu, Gly, and Pro) and SID (except for Arg, His, and Phe) of most AA. Most AA in diets showed higher AID (except for Lys) and SID (except for Lys, Met, and Ser) in broilers relative to laying hens. The AID and SID of all AA were significantly different between the three diets. In broilers, the AID and SID of most indispensable AA except for Arg in SBM and LCSM was higher than CSM. In laying hens, the AID and SID of most indispensable AA except for Arg, Met+Cys, and Phe in SBM was higher than CSM and LCSM. Conclusion: The accurate determination of AID and SID of AA in CSM and LCSM for broilers and layers benefits the application of CSM and LCSM in chicken diets. The cottonseed by-products CSM or LCSM showed the species-specific AA digestibility values for broilers and layers.
