Genetic evaluations of US dairy goats are calculated annually by USDA from records that are available through Dairy Herd Improvement programs and the American Dairy Goat Association (ADGA). The number of does in test plans used in genetic evaluations was 11,273 during 1999; participation in linear appraisal programs during 1999 was 3784 does, a decrease from the mean of 4285 does over the last ...

Milk production is an important livelihood source for smallholder dairy farmers in low-to-middle-income countries (LMICs) such as Kenya. However, milk quality and safety are a challenge due to unhygienic handling non-adherence food standards. The objective of this study was investigate the knowledge, attitudes adoption practices by Ten Focus Group Discussions (FGDs), involving 71 farmers, were ...

Background: Dairy work is thought to be predominantly a rural occupation. However, due preferences we see lot of urban residents consume fresh milk and hence, few people even in the areas take up cattle rearing as cost effective profession. In midst much talked re-emerging diseases, caused by close habitation animals man, it would very relevant living conditions these populations their hygiene ...

Genetic correlations between longevity and conformation traits were estimated using data on Czech Holstein cows first calved in the years 1993–2008. Longevity traits considered were length of productive life and number of lactations initiated and their functional equivalents (i.e. the longevity traits corrected for milk production). Conformation traits were twenty one linear descriptive type tr...

The aim of this experiment was to study the effects of pen size and parity on maternal behaviour of twin-bearing Small-Tail Han ewes. A total of 24 ewes were allocated to a 2×2 design (six per pen), with parity (primiparous or multiparous) and pen size (large: 6.0×3.0 m; small: 6.0×1.5 m) as main effects at Linyi University, Shandong Province, China. Behaviour was observed from after parturitio...

This study was carried out in order to determine the disinfectant effect of Methylated spirit® (95% methanol and 5% ethanol) as a teat dip against Listeria species. Hand milking was employed to collect 576 (288 x 2) raw milk samples from different lactating cows within Sokoto metropolis (Nigeria). 288 samples were collected before disinfecting the udder teats with Methylated spirit®, while the ...

AIM The aim of this study was to determine the epidemiological infestation and identification of Ixodidae and Argasidae ticks species in buffalo of different parts of district Khairpur, Pakistan. MATERIALS AND METHODS A total of 720 Water buffaloes from three tehsils (subdivisions) were selected randomly and examined from organized and unorganized dairy farms for tick infestation in district ...

Somatic cells are an important component naturally present in milk, and somatic cell count is used as an indicator of udder health and milk quality. The role of somatic cells in dairy processes and products is ill-defined in most studies because the role of these cells combines also the concomitance of physicochemical modifications of milk, bacterial count, and the udder inflammation in the pre...

Abstract Backgrounds The present study explored the viability of bovine milk macrophages, their intracellular production reactive oxygen and nitrogen species (RONS), phagocytosis Staphylococcus aureus , as well profile lymphocytes, from healthy udder quarters infected by Corynebacterium bovis . included 28 12 dairy cows 20 C. 10 cows. percentages macrophages lymphocytes were identified flow cyt...
