Genotypic stabilization of agronomic traits in Panicum maximum (Jacq.) hybrids

Thiago Gomes dos Santos Braz, Dilermando Miranda da Fonseca, Liana Jank, Cosme Damião Cruz, Janaina Azevedo Martuscello

DOI: 10.1590/S1806-92902015001100001

The objective of this study was to evaluate the genotypic stability of agronomic traits in hybrids of Panicum maximum. Hybrids originating from the crosses between two sexual parents and cultivars Mombasa and Tanzania were evaluated in an incomplete-block design. Evaluated traits were total dry matter, leaf dry matter, stem dry matter, percentage of leaves, and leaf:stem ratio. These traits were evaluated in six harvests. Overall, higher repeatability was observed for the traits total dry matter and leaf dry matter, especially […]

Keywords: coefficient of determination; forage; repeated measures; selection efficiency

DOI: 10.1590/S1806-92902015001100002

The objective of this study was to evaluate the chemical composition and yield of three sugarcane cultivars grown under Af climate conditions. Three sugarcane cultivars were examined, namely, IACSP93-6006, RB83-5486, and SP79-1011, in a randomized block design with three treatments, four blocks, and two replicates per block; means were compared using Tukey’s test at 5% probability level. Significant differences were observed for dry matter, ether extract, crude protein, acid detergent fiber, lignin (LIG), cellulose, neutral detergent fiber corrected for ash […]

Keywords: neutral detergent fiber; ruminant nutrition; whitewash

Comparison of fattening performance, carcass characteristics, and egg quality characteristics of Japanese quails with different feather colors

Hakan Inci, Bunyamin Sogut, Turgay Sengul, Ahmet Yusuf Sengul, Mehmet Resit Taysi

DOI: 10.1590/S1806-92902015001100003

The objective of this study was to compare fattening performance, carcass traits, and egg quality of Japanese quails with different feather colors (white, dark brown, golden, and wild-type). In the study, 360 one-day-old quail chicks with 4 different feather colors were used as animal material. Quails were fed ad libitum for 42 days to determine fattening performance and carcass traits. To determine egg traits, 48 hens from each group, in a total of 192, were selected and caged according to […]

Protein requirements for growth in male and female Saanen goats

Amélia Katiane de Almeida, Kléber Tomás de Resende, Simone Pedro da Silva, Diogo da Costa Soares, Márcia Helena Machado da Rocha Fernandes, Izabelle Auxiliadora Molina de Almeida Teixeira

DOI: 10.1590/S1806-92902015001100004

The objective of this study was to determine the protein requirements for the growth of intact male, female, and castrated male Saanen goats weighing 30 to 45 kg of body weight (BW) and to compare estimates of the protein requirements for maintenance (NPm) by the comparative slaughter and nitrogen balance techniques. To determine the maintenance requirements, 55 goats were assigned in a split-plot design using a 3 × 3 factorial arrangement (three sexes and three dry matter intake (DMI) levels). […]

Keywords: comparative slaughter; dairy; factorial approach; maintenance; nitrogen balance

DOI: 10.1590/S1806-92902015001100005

The objective of this study was to evaluate the characteristics of wool produced by ewes of different genetic groups, ages, and reproductive statuses. A total of 115 ewes, of the following genetic groups, were used: 10 Corriedale, 37 Hampshire Down, 26 1/2 Hampshire Down + 1/2 Corriedale, 24 1/2 Ile de France + 1/2 Corriedale, and 18 1/2 Suffolk + 1/2 Corriedale. Age was determined by the number of permanent incisors, ranging from four teeth to eight teeth. Ewes were […]
