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...

Moura, Marielly Maria Almeida; Pires, Daniel Ananias de Assis; Rodrigues, José Avelino Santos; Sales, Eleuza Clarete Junqueira de; Costa, Renê Ferreira; Tolentino, Daniella Cangussú.
 The objective was to select sorghum genotypes for silage production using its chemical characteristics. The experiment was carried out in the facilities of Embrapa Maize and Sorghum in Sete Lagoas, state of Minas Gerais, to evaluate the agronomic characteristics, and nutritional quality of silage of twelve sorghum genotypes. We used a randomized block design with three replications. In relation to the production of green matter, the genotypes SF15 Volumax and BR610 stood out (52.07; 48.00 and 41.87 ton ha-1). Regarding pH, genotypes 1015339, 1015347, 1016007, SF15, BRS655, Volumax and BR610 averaged 3.68. All genotypes were similar considering the nutritional value, ammonia nitrogen and water activity. The genotypes SF15, Volumax and BRS610 showed the...

Sales, Eleuza Clarete Junqueira de; Monção, Flávio Pinto; Machado, Silvia Layse Mendes; Ruas, José Reinaldo Mendes; Reis, Sidnei Tavares dos; Rigueira, João Paulo Sampaio; Pires, Daniel Ananias de Assis; Viana, Maria Celuta Machado; Silva, Edilaine Aparecida.
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...

Hay Tifton 85 grass under nitrogen doses in different days of regrowth Animal Sciences
Andrade, Weudes Rodrigues; Sales, Eleuza Clarete Junqueira de; Monção, Flávio Pinto; Gomes, Virgílio Mesquita; Rufino, Leidy Darmony de Almeida; Pires, Daniel Ananias de Assis.
The objective of this study was to evaluate the yield, nutritional value and potential ruminal degradation of Tifton 85 hay (Cynodon spp.) harvested at four regrowth ages (28, 35, 42 and 49 days) and fertilized with two nitrogen doses (N; 100 and 300 kg N ha-1). The experimental design was a randomized block design, arranged in a 4 x 2 factorial scheme, with six replications each. Nitrogen fertilization increased (p < 0.05) dry matter yield and digestible dry matter production of hay and also lignin and crude protein contents. Nitrogen fertilization increased (p < 0.01) the dry matter yield and the digestible dry matter production of hay, as well as lignin (p = 0.01) and crude protein (p = 0.01). The neutral detergent fiber corrected for ash and...

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...
