The Best Linear Unbiased Prediction (BLUP) methodology, which is widely used in animal and forestry genetic evaluation, can also be applied to annual crop breeding. The objective of this study was to compare the accuracy and efficiency of among- and within-half-sib family selection through the use of single- and multi-trait BLUP, and BLUE/ANOVA methods. Expansion volume and yield data from two recurrent selection cycles of a popcorn population were analyzed. Progeny tests were designed as a lattice. To maximize accuracy of the prediction of breeding values, the BLUP analyses included phenotypic values of the two cycles. All BLUP analyses were performed using the ASReml software. The multi-trait BLUP method demonstrated greater accuracy and efficiency in family selection. In the case of within-family selection, both accuracy and efficiency of multi- and single-trait BLUP methods were equivalent. The selection efficiency of the multi-trait BLUP was dependent on the estimated genetic parameters, particularly the difference between the genetic and environmental correlations of the traits. |

Digestibility of organic matter and crude fiber in forage was studied with nonparous females of water buffalo (Bosbubalis-Jaffarabadi breed), Zebu cattle (Bos indicus-Gir breed), and Holstein cattle (Bos taurus). Forages studied were low quality hay of molasses grass (Melines minutiflora) and silage of elephant grass (Pennisetum purpureum Schum). At time of ensiling, ground corn was added to the elephant grass at 10%, wet basis. The in vitro method of Tilley and Terry (12) was used to measure digestibility with rumen fluid of experimental animals as inocula when they were receiving a ration of the hay and then a ration of the silage. When animals were consuming the hay ration, digestibility of crude fiber by buffalo (40.0%) was greater than by Zebu (31.7%) or Holstein (29.1%). When they were consuming silage, which was of higher quality than the hay, buffalo and Zebu digested the fiber equally well and were superior to the Holstein digestibilities 46.4, 46.4, and 40.0%. Similarly, digestibility of organic matter was greatest by buffalo when animals consumed the hay ration; and when they were fed silage, digestibilities for buffalo and Zebu were similar and greater than for Holstein. With rations high in fiber and low in protein content, Jaffarabadi buffalo are superior to Gir and Holstein cattle for ability of inocula to digest crude fiber and organic matter. |
