The bull is the graph consisting of a triangle and two disjoint pendant edges. A graph is called bull-free if no induced subgraph of it is a bull. This is the first paper in a series of three. The goal of the series is to explicitly describe the structure of all bull-free graphs. In this paper we study the structure of bull-free graphs that contain as induced subgraphs three-edge-paths P and Q,...

the aim of this study was to determine the effects of the antioxidants superoxide dismutase (sod),glutathione peroxidase (gpx) and butylated hydroxytoluene (bht) on microscopic semen parameters andlipid peroxidation following the freeze-thawing of bull semen. ejaculates were collected from five holsteinbulls and pooled at 37°c. the semen samples were diluted with a cey extender containing addit...

The bull is a graph consisting of a triangle and two vertex-disjoint pendant edges. A graph is called bull-free if no induced subgraph of it is a bull. A graph G is perfect if for every induced subgraph H of G, the chromatic number of H equals the size of the largest complete subgraph of H. This paper describes the structure of all bull-free perfect graphs.

The present study was conducted at Sabarmati Ashram Gaushala, Bidaj, Gujarat. A total of 427 donor animals were investigated over a ten-year period to assess the efficiency Standard protocol Multiple Ovulation and Embryo Transfer (MOET). Simultaneously season wise breed also conducted. Breeds studied Gir, HF, HFCB, Jersey, JYCB, Red Sindhi Sahiwal. Overall average number embryos, viable pregnan...

The bull is a graph consisting of a triangle and two pendant edges. A graph is called bull-free if no induced subgraph of it is a bull. This is a summary of the last two papers [2, 3] in a series [1, 2, 3]. The goal of the series is to give a complete description of all bull-free graphs. We call a bull-free graph elementary if it does not contain an induced three-edge-path P such that some vert...
