Agronomic characteristics of sorghum genotypes and nutritional values of silage Animal Sciences
Costa, Renê Ferreira; Pires, Daniel Ananias de Assis; Moura, Marielly Maria Almeida; Sales, Eleuza Clarete Junqueira de; Rodrigues, José Avelino Santos; Rigueira, João Paulo Sampaio.
The objective was to assess agronomic characteristics of sorghum genotypes and nutritional values of produced silage. A total of 15 sorghum genotypes were used. Planting was carried out through a randomized-block design with three replications per genotype, totaling forty-five (45) plots. Agronomic and nutritional characteristics, besides the quality of the silage, were assessed. There were differences between genotypes for all characteristics analyzed, with the exception of levels of acid detergent unavailable nitrogen (ADUN), acid detergent unavailable protein (ADUP) and water activity (aw). The assessment of the parameters, except for genotypes 1016013, 1016025, 1016037, 1016039, Volumax and BRS 610, which presented protein level below 7%, showed that...

 The objective of this study was to assess agronomic characteristics and nutritional values of silages of millet genotypes. Planting was done in randomized blocks, with five replicates per genotype. Green matter yield for genotypes ADR 500 and CMS 01 was higher and similar to each other, with 40.16 and 41.36 t ha (p > 0.05). There was no significant difference for dry matter yield, with the mean being 9.93 t ha (p > 0.05). The silages were similar (p > 0.05) as to pH, Aw and N-NH3/TN, presenting values of 3.92, 0.97 and 7.64%, respectively. There were no significant differences (p > 0.05) concerning the bromatological composition of the silages of the different genotypes, with a mean of 30.74% of dry matter, 10.21% for crude protein and 58.69%...

The objective of this work was evaluate the association between morphogenetic and structural characteristics of Brachiaria decumbens managed at different doses of nitrogen. The experimental design was a randomized block with four replications. Four levels of nitrogen fertilization were evaluated: 100; 200; 300 and 400 kg of N ha-1 as urea, divided in two doses during the rainy season (January to March) and the control treatment without fertilization. There was an increase in leaf appearance rate (LAR), leaf elongation rate (LER) and tiller number (NP) up to 21.4%; 23.8% and 50.5% for the highest dose of N (400 kg N ha-1) compared to the control group, respectively. There was a positive correlation (r = 0.53) (p<0.05) between the LER and leaf life span...

Fermentation kinetics and in vitro degradation rates of grasses of the genus Cynodon Animal Sciences
Reis, Sidnei Tavares dos; Lima, Marcus Vinícius Gonçalves; Sales, Eleuza Clarete Junqueira de; Monção, Flávio Pinto; Rigueira, João Paulo Sampaio; Santos, Leonardo David Tuffi.
The present study aimed to evaluate the fermentation kinetics and degradation rates of Cynodon grasses estimated by semi-automated technique of in vitro gas production. The forages were: Coastcross, Tifton 85 and Tifton 68. Pressure readings were taken at 0, 2, 4, 6, 8, 10, 12, 15, 19, 24, 30, 36, 48, 72 and 96 hours. Dry matter degradability (DMD) was obtained by the percentage of dry matter (DM) remaining after 0, 6, 12, 24, 48 and 96 hours of fermentation. Tifton 85 showed a higher total gas production (p <0.05). Higher fermentation rates were found at the beginning of fermentation followed by subsequent reduction (p <0.05) over time. Tifton 85 and Tifton 68 showed higher values (p < 0.05) for soluble fraction, potentially degradable insoluble...

Fermentative characteristics and nutritional value of elephant grass silage added with dehydrated banana peel Animal Sciences
Brant, Lara Maria Santos; Pimentel, Paulo Roberto Silveira; Rigueira, João Paulo Sampaio; Alves, Dorismar David; Carvalho, Mateus Alves Macedo; Alves, Wagner Sousa.
The aim of this study was to evaluate the fermentative losses and nutritional value of elephant grass silages with the increasing of inclusion levels of dehydrated banana peel. The experiment was conducted in a completely randomized design, with six treatments and four replications, being the silage exclusively from elephant grass, and five levels of inclusion of banana peel to the elephant grass silage, as the following - 5; 10; 15; 20 and 25%, being added based on natural matter. The addition of the banana peel in the silage reduced linearly (p < 0.05) the pH, the ammoniacal nitrogen and the losses of the fermentative process. In addition, the inclusion of banana peel increased linearly (p < 0.05) the dry matter and non-fibrous carbohydrates. On...

Leite, João Ricardo Avelar; Sales, Eleuza Clarete Junqueira de; Monção, Flávio Pinto; Guimarães, Adriano de Souza; Rigueira, João Paulo Sampaio; Gomes, Virgílio Mesquita.
 This study aimed to evaluate the structural, productive and nutritional characteristics of cactus pear (Nopalea cochenillifera Salm Dyck. cv. Miúda/Doce) under five nitrogen doses and two planting orientations. A randomized block design in a 5 x 2 factorial scheme was used in the scheme: five nitrogen doses (0, 150, 300, 450 and 600 kg of N ha-1), and two planting orientations (North/South and East/West), with three replicates. Except for the thickness of the secondary (p = 0.04) and tertiary cladodes (p = 0.02), the morphometric characteristics of the cactus pear were not influenced by the nitrogen doses (p > 0.05). The mean height was 120 cm, the areas of the primary, secondary and tertiary cladodium were 160.9; 208 and 158.4 cm², respectively. The...

 This study aimed to evaluate the nutritional characteristics and quality of silages of five sorghum genotypes, namely: Volumax, AG2005E, Qualimax, BRS610 and AG2501. The study was conducted at the Experimental Farm Unimontes, in the municipality of Janaúba, state of Minas Gerais. The treatments were distributed in a randomized block design with four replicates. Data were tested by analysis of variance andmeans were compared by Scott-Knott test at a significance level of 5%. The pH values ranged from 3.93 and 4.10. Genotypes differed in all studied nutritional characteristics (p < 0.05). For the acid detergent fiber, differences were detected between the genotypes, AG2501 (35.66%), Volumax (34.89%), AG2005E (34.53%), Qualimax (32.39%) and BRS610...

Spínola, Jaime Emerson Laranjeira; Tavares dos Reis, Sidnei; Junqueira de Sales, Eleuza Clarete; Monção, Flávio Pinto; Rigueira, João Paulo Sampaio; Delvaux Júnior, Nelson de Abreu.
This study aimed to determine and measure the phenolic acids in four varieties of sugarcane (RB 855536, RB 765418, SP 80-1842 and SP 80-1816) as fresh and ensiled, and assess the influence of these acids on in situ degradability of dry matter and neutral detergent fiber. The experimental design was completely randomized in a factorial design. For the fraction of dry matter (DM), varieties RB 855536 and SP 80-1842 had average 17.80% higher compared to others. The SP80-1842 and RB 855536 varieties did not differ (p > 0.05), with an average of DM effective degradability of 33.70%. For silage, the highest levels of p-coumaric acid were found in the variety RB 855536, which was 24.64% higher than the varieties RB 765418 and SP 80-1842 (average 12.75%) and...

Rigueira, João Paulo Sampaio; Pereira, Odilon Gomes; Valadares Filho, Sebastião de Campos; Ribeiro, Karina Guimarães; Garcia, Rasmo; Cezário, Andreia Santos.
This experiment evaluated the effect of molasses with or without microbial additive on soybean silage regarding the intake, digestibility and growth performance of beef cattle. The experimental design used was randomized blocks with four treatments (diets with soybean silage (SS), SS with microbial inoculant, SS with molasses and SS with microbial inoculant and molasses) and seven replications. Animal were feedlot fed for 99 days. Diets contained forage: concentrate ratio of 70:30, the forage consisted of 40% soybean silage and 30% corn silage. There was lower intake of nutrients in the diet containing SS in relation to the SS diet added with inoculant and molasses. The diet containing SS with inoculant and molasses presented higher apparent digestibility...
