A gastric lymphoid tumor with involvement of regional lymph nodes and spleen was diagnosed in an 8-year-old crossbreed male dog with a 6-month history of gastrointestinal disease. Despite surgical excision and palliative therapy (prednisolone and cimetidine), the dog was euthanatized due to worsening of clinical signs. At necropsy, multiple white, solid, nodular, infiltrative masses were observ...

In previous papers in this series (5, 8, I3) it has been shown that spontaneous malignant melanomas are produced in the hybrid offspring of the black-spotted platyfish, Platypoecilus maculatus, and the swordtail, Xiphophorus hdlerii. The melanomas are evoked genetically in hybrids by the interaction of the sexlinked, heritable factor for macromelanophores, Sp, of the platyfish with a series of ...

Segregation between a genetic marker and a locus influencing a quantitative trait in a well delineated population is the basis for success in mapping quantitative trait loci (QTL). To detect bovine chromosome 5 (BTA5) birth weight QTL we genotyped 294 F2 Gyr (Bos indicus) x Holstein (Bos taurus) crossbreed cattle for five microsatellite markers. A linkage map was constructed for the markers and...

This study aims to evaluate milk production, consumption and digestibility of rations in Etawa Crossbreed Dairy Goats (ECDG) fed with concentrate palm kernel cake (CPKC), tithonia (Tithonia diversifolia) corn waste. The design used was a completely randomized 4 treatment 5 replications. Treatment A = 7.5 kg titonia + tofu waste, B 2 waste 1.2 CPKC, C 5.5 D 3.5 CPKC. Data were analyzed by ANOVA ...

A total of 1020 crossbreed rabbits were individually examined to evaluate their welfare at electric stunning and slaughtering in a commercial abattoir. Stunning (position of electrodes and repetition of current applications) and sticking (position, length and depth of the cut) procedures were checked. Rabbits were behaviourally monitored from current application to death. The stunning system wa...

Eleven cases of pyometra were diagnosed in a captive exotic felid collection over 3 yr in seven African lions (Panthera leo), two tigers (P. tigris), one liger (lion-tiger crossbreed), and one leopard (P. pardus). Clinical signs included anorexia, lethargy, vulvar discharge, and vomiting. Diagnosis was based on clinical signs, complete blood cell counts, plasma biochemistry and electrolyte valu...

Hybridization refers to the crossing breeding of two plants. Coefficient of Parentage (COP) is used by the plant breeders to determine the genetic diversity across various varieties so as to incorporate the useful characters of the two varieties to develop a new crop variety with particular useful characters. Genetic Diversity is the prerequisite for any cultivar development program. Genetic Di...

The effect of water supply – especially of drought stress – on the content of some secondary metabolites in hops (Humulus lupulus L.) was studied. The experiment took place in 2006. Some relevant data from 2005 were included for comparison. Leaves and cones of nine hop cultivars grown under field conditions as well as in a pot experiment under three water regimes were analyzed. The cultivars ra...
