The main objective of the present work was to study nutritive strategies for lessening the CH4 formation associated to ruminant tropical diets. In vitro gas production technique was used for evaluating the effect of tannin-rich plants, essential oils, and biodiesel co-products on CH4 formation in three individual studies and a small chamber system to measure CH4 released by sheep for in vivo studies was developed. Microbial rumen population diversity from in vitro assays was studied using qPCR. In vitro studies with tanniniferous plants, herbal plant essential oils derived from thyme, fennel, ginger, black seed, and Eucalyptus oil (EuO) added to the basal diet and cakes of oleaginous plants (cotton, palm, castor plant, turnip, and lupine), which were included in the basal diet to replace soybean meal, presented significant differences regarding fermentation gas production and CH4 formation. In vivo assays were performed according to the results of the in vitro assays. , when supplemented to a basal diet (Tifton-85 hay sp, corn grain, soybean meal, cotton seed meal, and mineral mixture) fed to adult Santa Ines sheep reduced enteric CH4 emission but the supplementation of the basal diet with EuO did not affect ( > 0.05) methane released. Regarding the microbial studies of rumen population diversity using qPCR with DNA samples collected from the in vitro trials...

Foram conduzidos 2 estudos com vacas leiteiras no Departamento de Zootecnia da ESALQ/USP com os objetivos de avaliar a utilização de fonte de uréia de liberação lenta (Optigen ®) e ID (intervalos de desfolhas) fixos ou variáveis em pastagens de capim Elefante. No Experimento 1, foram utilizadas 32 vacas no terço médio de lactação, produzindo 20,8 kg leite dia-1 e pesando 524 kg no início do período experimental. O tratamento controle (C) continha apenas farelo de algodão como suplemento protéico. No tratamento U30, 30 % da PB do farelo de algodão foi substituída por uréia. No tratamento O30, 30% da PB do farelo de algodão foi substituída pela uréia de liberação lenta e no tratamento O60, 60% da PB do farelo de algodão foi substituída pela uréia de liberação lenta. O delineamento experimental adotado foi o quadrado latino 4 x 4 com 8 repetições e as variáveis foram analisadas utilizando o PROC MIXED (SAS). A produção de leite não diferiu (P>0,05) entre os tratamentos C (20,2 kg dia-1), O30 (19,8 kg dia-1) e U30 (19,5 kg dia-1).

Este experimento foi realizado para avaliar o efeito do farelo e da farinha de algodão no comportamento reprodutivo e na atividade testicular de reprodutores de tilápia do Nilo. Vinte e cinco peixes receberam dietas contendo 0; 2; 4; e 6% de semente de algodão descorticada e moída e 24,0% de farelo de algodão. O comportamento reprodutivo foi observado e a construção de ninhos, corte e desova, avaliadas. Aos 90 dias, as gônadas dos machos foram avaliadas microscopicamente. O grupo controle (farelo de algodão) obteve maior número de desovas. Os peixes alimentados com semente ou farelo de algodão, apesar de não terem apresentado o mesmo número de desovas, construíram ninhos e fizeram a corte. A análise histológica dos testículos demonstrou que a adição de 24,0% de farelo ou níveis de 2,0% ou superiores da farinha influiu na atividade testicular. O gossipol presente na farinha ou farelo de algodão teve efeito negativa nas gônadas destes animais.; This experiment was conducted to evaluate the effect of cottonseed meal and cotton seed flour on the reproductive behavior and on the testis activity of Nile tilapia broodstock.

Thirty 3/4 Canchim + 1/4 Nelore young bulls with 417 kg of body weight and 15 months of age, were confined during 84 days. The animals were fed with diets composed with corn silage, corn grain, cottonseed meal, soybean meal, whole soybean and mineral mix, adjusted in agreement with the recommendations of the Metabolizable Protein System (MP), Cornell Net Carbohydrate and Protein System (CNCPS) and Intestine Digestible Protein System (PDI), for predicted body weight gain of 1.3 kg/head/day. The daily body weight gain did not differ among treatments CNCPS, MP and PDI, with 1.51; 1.48; and 1.13 kg/head, respectively. The economic analysis revealed net profit of R$116.25; R$148.30; and R$108.51/head for CNCPS, MP and PDI systems, respectively. The diets adjusted by CNCPS and MP systems provided superior animal performance than that expected, while the diet adjusted by PDI system did not allow the predicted body weight gain.

Evaluation of abundantly available agro-industrial by-products for their bioactive compounds and biological activities is beneficial in particular for the food and pharmaceutical industries. In this study, rapeseed meal, cottonseed meal and soybean meal were investigated for the presence of bioactive compounds and antioxidant, anti-inflammatory, xanthine oxidase and tyrosinase inhibitory activities. Methanolic extracts of rapeseed meal showed significantly (P < 0.01) higher phenolics and flavonoids contents; and significantly (P < 0.01) higher DPPH and nitric oxide free radical scavenging activities when compared to that of cottonseed meal and soybean meal extracts. Ferric thiocyanate and thiobarbituric acid tests results showed rapeseed meal with the highest antioxidant activity (P < 0.01) followed by BHT, cotton seed meal and soybean meal. Rapeseed meal extract in xanthine oxidase and tyrosinase inhibitory assays showed the lowest IC50 values followed by cottonseed and soybean meals. Anti-inflammatory assay using IFN-γ/LPS stimulated RAW 264.7 cells indicated rapeseed meal is a potent source of anti-inflammatory agent. Correlation analysis showed that phenolics and flavonoids were highly correlated to both antioxidant and anti-inflammatory activities. Rapeseed meal was found to be promising as a natural source of bioactive compounds with high antioxidant...

Fifty-one Simmental crossbred steers (357.0±16.5 kg) were used to compare a standard total mix ration (TMR) with variants on animal performance, ruminal fermentation, blood biochemical parameters, and carcass characteristics. Corn grain and cotton seed meal were partially replaced by ensiled mulberry leaves (EML) or sun-dried mulberry fruit pomace (SMFP). Experimental diets had similar amounts of crude protein (CP), acid detergent fiber (ADF), and metabolizable energy (ME). Animals were divided into three groups: control group (CONT), 8% EML group, and 6.3% SMFP group. Performance, including average daily weight gain (ADG), and dry matter intake (DMI), was measured. Blood and rumen samples were collected at the end of the experiment (16 weeks). There were no differences in final body weight (P = 0.743), ADG (P = 0.425), DMI (P = 0.642), or ADG/DMI (P = 0.236) between the groups. There were no differences (P = 0.2024) in rumen pH values; ammonia N was lower (P = 0.0076) in SMFP than in the EML and CONT groups. There were differences in the concentrations of total and individual volatile fatty acids, while no differences were determined in blood biochemical parameters (i.e., plasma glucose, urea concentrations...

The objective of this study was to investigate the effect of levels of cottonseed meal with various carbohydrate sources in concentrate on feed intake, nutrient digestibility, rumen fermentation and microbial protein synthesis in dairy bulls. Four, 6 months old dairy bulls were randomly assigned to receive four dietary treatments according to a 2×2 factorial arrangement in a 4×4 Latin square design. Factor A was carbohydrate source; cassava chip (CC) and cassava chip+rice bran in the ratio of 3:1 (CR3:1), and factor B was cotton seed meal levels in the concentrate; 109 g CP/kg (LCM) and 328 g CP/kg (HCM) at similar overall CP levels (490 g CP/kg). Bulls received urea-lime treated rice straw ad libitum and were supplemented with 10 g of concentrate/kg BW. It was found that carbohydrate source and level of cotton seed meal did not have significant effects on ruminal pH, ammonia nitrogen concentration, microbial protein synthesis or feed intake. Animals which received CC showed significantly higher BUN concentration, ruminal propionic acid and butyric acid proportions, while dry matter, organic matter digestibility, populations of total viable bacteria and proteolytic bacteria were lower than those in the CR3:1 treatment. The concentration of total volatile fatty acids was higher in HCM than LCM treatments...

This paper analyzes and compares the structure of cotton by-products industries in selected countries (Uganda, Tanzania, Benin, and Burkina Faso) in the context of the global vegetable oil market. It reaches several conclusions. First, because the markets for various edible oils are highly integrated with each other, examination of each oil market should be done in conjunction with all other (relevant) edible oil markets. Second, the recent surge in demand for commodities used as feedstocks for biofuels is unlikely to become a new source of growth for the cotton oil market. Third, within the context of deepening the on-going reform efforts in West and Central African countries, cotton by-products should be taken into consideration, both in terms of the cotton price setting mechanism and the size of the organization of the cotton by-products industry. Fourth, trade policies including export bans or import tariffs to protect the domestic crushing industries, and policies that favor crude over refined oils...

Cotton production is truly a success story in West and Central Africa. The region is now the second largest exporter of lint, after the United States, with a world market share of 15 percent. Despite its strong performance in the past, the sector is characterized by several institutional and structural weaknesses that jeopardize its viability in an era of increasing globalization of the cotton industry. The sector's future performance will also depend on the implications of cotton sector policies in major producing countries such as the United States, the European Union, and China. This paper examines how the above factors may affect future growth of the region's cotton industry. It also identifies the changes that are required to enable countries in the region to fully exploit the sector's significant growth potential.

It has been shown that cassava starch can be converted into alcohol most efficiently when fungal enzyme preparations from submerged cultures are used to hydrolyze the starch into sugar. The use of barley malt in the process for conversion of cassava starch has resulted in alcohol yields of 70-74% of the theoretical. Cassava mashes converted by submerged fungal cultures (Aspergillus niger van Tieghem, strain NRRL-337) resulted in alcohol yields up to 90% of the theoretical. Substitutes for the distillers'dried solubles-corn medium were tried. Screened cotton seed meal and soybean meal proved to be a satisfactory substitute for distillers'dried solubles. Dehydrated cassava meal was effectively used in place of corn meal. A comparative study was carried out using several molds from the Collection of the Instituto Agronômico for the purpose of determining their enzyme activity. The mold that presented the highest enzyme potency was found to be the strain of Aspergillus oryzae (Ahlburg) Cohn strain F-27 which had been originally isolated from saké (rice wine). Studies of the dehydrated residues (7% moisture) from hydrolized and fermented mash were found to contain approximately 25% protein indicating their possible value in animal feeds. Simple substrates can be used for the propagation of the mold which is a very efficient conversion agent. It is...

This paper deals with a field trial executed to compare cotton seed and cacau meals in the fertilization of sugar cane, variety Co290. The design chosen was a latin square of 6 x 6. The following conclusions can be drawn: 1. Cottonseed meal revealed to be statistically superior to cacau meal, being even superior to the mineral fertilizers plus cacau meal treatment. 2. From an economical point of view cotton seed meal, as a fertilizer for sugar cane, can not be substituted by cacau meal.

The present research work has been carried out with the aim to study the digestibility of nitrogen fractions, in animals fed with different nitrogen sources rations. The diets were supplied to Holstein steers with abomasal cannulas, with eight months of age and average weight of 187 kg, in a total of 21 animals selected at random. The experimental rations were constituted by 40% roughage (Rhodes grass hay) and 60% concentrate (corn, cotton seed meal, yeast, urea, molasses and minerals) by concentrate mixture. The utilized treatments were: RA (ration with cotton seed meal); RL (ration with yeast); RU (ration with urea). The amount of nitrogen (N) intaked in grams per day (g/day) in relation of metabolic weight (g/kgLW0.75) did not display significant differences (P > 0.05) with the change of nitrogen source of diets. Also the N present in abomasum (g/day) did not display significant differences (P > 0.05). The N apparent digestibility was superior (P < 0.05) in RU diet (53.61%) when compared to RA and RL diets (46.66 and 46.37%, respectively). RA and RL diets, despite presenting the largest amount of NNA in the abomasum (71.75 and 72.38 g/day respectively) in relation to RU diet (P < 0.05), were the ones that present the largest amounts eliminated in feaces as well (37.74 and 41.20 g/day...
