BACKGROUND Congenital sensorineural deafness has been reported frequently in experimental mixed-breed white cats but there is a paucity of data on occurrence of deafness in client-owned pure-breed white cats. OBJECTIVE To describe hearing status in client-owned pure-breed white cats. ANIMALS Eighty-four pure-breed client-owned cats with white coat color of 10 registered breeds presented for...

During the domestication process, dogs were selected for their suitability for multiple purposes, resulting in a variety of behavioral characteristics. In particular, the ancient group of breeds that is genetically closer to wolves may show different behavioral characteristics when compared to other breed groups. Here, we used questionnaire evaluations of dog behavior to investigate whether beh...

Any producer contemplating the prospect of sheep dairying will face the problem of breeds: which breeds or what type of animals to purchase (or develop) in order to have the most economical commercial milk production? The problem is not an easy one to solve because there is not a single breed that combines all favorable traits. Some breeds are better than others in producing milk and others are...

This study aimed to assess genetic diversity within and between nine Vietnamese local chicken breeds and two Chinese breeds included for comparison. Genotyping 29 microsatellites revealed high diversity of both Vietnamese and Chinese breeds. Cluster analysis using the STRUCTURE software suggested six clusters as the most likely grouping of the 11 breeds studied. These groups encompassed four ho...

The aim of the present research is to investigate breeders’ management strategies and their effects on reproductive performances in heritage breeds. A total 468 litters were analysed: Belgian Hare (N = 151), Burgundy Fawn 105), Californian 212). Litter size (born alive), percentage weaned kits selected analysed using a model that included breed, year birth, litter’s origin (with three levels: b...

Effects of Dorset, Finnsheep, Romanov, Texel, and Montadale breeds for performance as sires were estimated in the initial phase of a comprehensive evaluation of these breeds as contributors to sheep crossbreeding systems. Objectives were to evaluate the effects of ram breed, ewe breed, season of mating, and two-way interactions. Rams from the five breeds were single-sire-mated with ewes from tw...

The objective of this study was to determine the relationship between body weight (BW) and heart girth (HG) in Sardi and Timahdite sheep in order to develop a prediction equation of BW from HG. The data used for this study included 476 records on BW and HG (227 in Sardi and 249 in Timahdite) collected on males and females of different ages in 33 private farms. The BW and the HG averaged 34.8 ± ...

Weight and feed consumption of 197 bulls were recorded monthly in a serial slaughter experiment continuing over a period of 24 mo. The bulls were produced in a modified five-breed diallel of the Angus, Brahman, Hereford, Holstein and Jersey breeds. Our objective was to estimate efficiency of feed conversion for weight gain for each breed and cross. The model included average weight gain per day...
