Four crossbred bovines (Zebu x Holstein) fed in nature, hydrolyzed, hydrolyzed sugar cane hay and silage as roughage sources constituting 70% of the diets were used to study the effect of alkali treatment of sugar cane (1.5% of NaOH at 50%) on dietary total digestibility and dry matter intake and rate of passage of sugar canes. The fiber was the most influenced fraction by the alkali treatment and increased at least by 45% of digestibility. The increases of 25.0 and 16.7% on intake of hydrolyzed- (1.5% BW) and hydrolyzed sugar cane hay-based diets (1.4% BW) were probably influenced by the higher fiber digestibility. The estimated values of ruminal and cecco-colon rate of passage and retention time in each treatment did not differ among in nature, hydrolyzed and hydrolyzed sugar cane hay-based diet, whereas the lowest rates (1.5 and 7.4%/h) and highest retention time (71.4 hours) were observed for the hydrolyzed silage. It was concluded that alkali treatment with sodium hydroxide, with or without sugar cane hay, increased fiber digestion of hydrolyzed sugar cane in total tract and increased intake, without effect on passage rate. However, post ensilage of hydrolyzed sugar cane could not show effects.

The objective of this study was to evaluate different inclusion levels (0, 20, 40 and 60%) of old man saltbush in the fermentation dynamics of sugarcane silages. The experiment was carried out as a completely randomized design with four treatments and six replicates. After 90 days, with the opening of the silos, the levels of water soluble carbohydrates, ethanol, organic acids (lactic, acetic, propionic, butyric acid), crude protein (CP), mineral matter (MM), dry matter (DM), neutral detergent fiber ash free (NDFa), pH and buffer capacity were determined; and, the losses by gas, effluent and total of dry mater, density and dry matter recovery were estimated. Increasing levels of saltbush propitiated reduction in losses: by effluent and total dry matter, it also increased the concentration and recovery. The silages showed pH suitable for conservation (≤3.70) and mineral concentration increased. The ethanol concentrations were influenced (P<0.05) by the increase of saltbush, where reduction of 51.84% was observed, with 40% saltbush in sugarcane silage. The addition of saltbush reduces dry matter losses and ethanol production and, improves the quality of sugarcane silage.

The objective of this present trial was to evaluate the chemical composition and in vitro dry matter digestibility (IVDMD) of sugarcane cultivars receiving different levels of irrigation water. It were evaluated the cultivars RB 96-1003, RB 94-3206, RB 72454, RB 01-2018, VAT 90-212, RB 01-2046 and RB 92-579 that received irrigation water of 100%, 80%, 60% and 40% based on real evapotranspiration of sugarcane (ETc) in a completely randomized blocks experimental design and factorial arrangement. Each experimental unit was constituted by cultivation in double lines and the irrigation system was subsurface drip irrigation with compensating emitters. Twelve months after planting, the sugarcanes were cut to determine levels of dry matter (DM), ash, organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE) and IVDMD. The cultivars RB 943206 and RB 01-2018 were positively highlighted in relation to CP levels, although RB 961003 had highlighted for IVDMD. Using irrigation of 100% of ETc were obtained higher DM and lower IVDMD values in comparison with others.

The aim of this study was to identify parents and promising hybrid combinations for the improvement of forage watermelon. Five parents were evaluated: BGCIA 996 (1), BGCIA 997 (2), BGCIA 998 (3), BGCIA 228 (4), Jojoba (5) and ten F1 hybrids, which were obtained from balanced diallel crosses. The experimental design was in a complete randomized block, with three replications. The morphoagronomic and bromatological traits were evaluated. The highlights were the progenitors BGCIA 997, BGCIA 998, BGCIA 228 and Jojoba for protein content, fruit yield, in vitro digestibility of dry matter and number of seeds, respectively. The hybrid 1x4 stood out for fruit length, seed number, and ethereal extract. The hybrid 2x3 stood out for rind and pulp thickness while the hybrids 3x4, 3x5 and 4x5 had exceptional digestibility, protein content and fruit yield, respectively. The analysis of the standard deviation of the SCA estimates of both SD (SijSik) and SD (SijSkl) indicated that no hybrids were found that had SCA estimates twice that of SD (SijSik) or SD (SijSkl), except for the hybrid 1x4 for the number of seeds per fruit. These results suggest that the parents were more promising than the hybrids. Similarly, the GCA estimates favor the intrapopulation method, which will promote greater efficiency in selection for genetic gains.

The use of alternative foods, such as agroindustrial residues, for animal feeding aims to reduce production costs and increase animal productivity. Therefore, the objective of this study was to evaluate the effect of different levels of licury cake added to the diet of non-standardbred lambs (NSB). The study involved 20 male castrated NSB lambs, with an average age of 120±5 days and initial and final average weights of 25±2 kg and 34±2 kg, respectively; the lambs were kept in a feedlot and distributed in a completely random block design for 75 days. Three isonitrogenic diets (17% protein) with three levels of licury cake supplementation (8, 16 and 24%) and a control diet (0% licury cake) were used. Elephant grass (Pennisetum purpureum) concentrate in a 50:50 ratio and the different levels of licuri cake were provided twice a day. The residue normality and variances compared by orthogonal and polynomial regression contrasts were verified for data analysis at 5% significance. The licury cake levels did not influence (P>0.05) the dry matter intake, minimum and maximum fat thickness, empty gastrointestinal tract, spleen, heart, kidneys, anterior and posterior quarters, muscle yield, marbling, other tissues or ash. There was a quadratic effect (P<0.05) for the average daily weight, skin yield and crude protein. Increasing the levels of licury cake reduced (P<0.05) real yield, loin eye area, and increased (P<0.05) leg yield, bone and moisture. A diet including up to 13% licury cake can be indicated as an alternative feeding source for feedlot NSB sheep.

Application of organic agroindustrial residues on agriculture can be one way to improve the development and chemical composition of plants, reducing the cost with chemical fertilizers and impacts generated by the excessive use of them. Sugarcane agroindustrial residue has been generated in high quantity in Brazilian semiarid region and can be applied to cassava crop to improve its growth. The aim of this work was to evaluate the effect of application of sugarcane agroindustrial residue on the vegetative development, chemical composition and mycorrhizal association of cassava plants (Manihot esculenta var. Engana ladrao). It was performed an experiment in greenhouse with completely randomized design

Preserving forage plants adapted to a semi-arid climate as silage may minimize the animal feed deficit during drought. The objective of this study was to evaluate the effects of different quantities of grape pomace added to Calotropis procera silage on its fermentation, in vitro digestibility, total digestible nutrients and microbiology. A completely randomized experimental design was used with four treatments (0, 10, 20 and 40% fresh matter) and four replicates. The silos were opened after 90 days of ensilage, and the soluble carbohydrate, ethanol, organic acid and ammoniacal nitrogen concentrations; pH; fermentation loss; dry matter (DM) recovery; DM density, and microbial populations were determined. The pH (3.96-3.87) was adequate for ensiling in all silage samples. The soluble carbohydrate concentration decreased (p<0.05), and the ethanol concentration increased with increasing quantities of grape pomace. The lactic acid concentration decreased (p<0.05) from 5.3 to 1.94% DM, and the acetic, propionic and butyric acid concentrations increased with increasing quantities of grape pomace. The lactic acid bacteria decreased linearly (p <0.05), varying from 6.43 to 5.82 log CFU/g silage. The mold and yeast population variations fit best using a third-order polynomial equation (p <0.05). Enterobacteria and Clostridium spp were not observed. Adding grape pomace to the silage increased the effluent and gas loss; the latter varied from 5.35 to 14.4%. The total digestible nutrient (TDN) variation fit best using a second-order polynomial equation, and the maximum value was estimated at 82.95% DM with 3.5% grape pomace using the regression equation. The percent digestibility decreased linearly (p<0.05) with increasing quantities of grape pomace. We show that Calotropis procera has potential as silage even without adding grape pomace.

Objetivou-se quantificar em silagens de cana-de-acucar com diferentes niveis de inclusao de erva-sal (Atriplex nummularia Lindl.) os teores de carboidratos soluveis, producao de etanol, pH e poder tampao. Utilizou-se o delineamento inteiramente casualizado; os tratamentos consistiram de 0, 20, 40 e 60% de erva-sal em substituicao a cana-de-acucar com seis repeticoes cada. As forragens em suas proporcoes experimentais foram armazenadas em silos (baldes plasticos) de 25 litros adaptados com valvula do tipo Bunsen. Apos periodo de fermentacao de 90 dias, os silos foram abertos e coletaram-se amostras para obtencao do extrato aquoso, no qual foram determinados pH, poder tampao, teores de carboidratos soluveis (CHOSol) e etanol. A adicao de erva-sal proporcionou diminuicao (P<0,05) das concentracoes de etanol nas silagens avaliadas, onde se verificou reducao de 60,08%, considerando-se os niveis 0 e 40% de Atriplex sobre a silagem de cana-de-acucar. Observou-se ainda com o incremento de erva-sal, pH adequado a conservacao (≤ 3,7). A inclusao de erva-sal reduz a producao de etanol e melhora a qualidade fermentativa da silagem de cana-de-acucar.

Objetivou-se avaliar os niveis de salinidade da agua de beber na composicao tecidual e medidas do lombo de cordeiros Santa Ines. Foram utilizados 32 cordeiros, com idade media inicial de nove meses e peso medio de 20 kg, distribuidos em delineamento inteiramente casualizado em quatro niveis de salinidade da agua de beber (T1= 640 mg de solidos dissolvidos totais (SDT) na agua - 1 dS/m; T2= 3.188 mg SDT na agua - 5 dS/m; T3= 5.740 mg SDT na agua - 9 dS/m e T4= 8.326 mg SDT na agua - 13 dS/m), com oito repeticoes. Os cordeiros foram alimentados com feno de capim buffel e concentrado (milho, farelo de soja, nucleo vitaminico e mineral), com relacao volumoso: concentrado de 50:50, fornecida ad libitum. Ao final do periodo experimental (73 dias), os animais foram pesados e abatidos com peso medio de 26,69 ± 1,19 kg. Apos 24 horas em câmara frigorifica, as carcacas foram divididas longitudinalmente e a metade esquerda seccionada em seis regioes anatomicas. No corte do lombo foram feitas mensuracoes no perfil do musculo Longissimus lumborum para determinacao da area de olho de lombo. O lombo foi dissecado, separando-se os principais tecidos. Os rendimentos medios obtidos foram de 48,62%, 28,99% e 15,34% para o musculo, osso e gordura total, respectivamente. O fornecimento de aguas salinas ate o nivel de 8.326 mg SDT na agua para cordeiros pode ser indicado, pois nao causam alteracoes na composicao tecidual e medidas de seus lombos.
