Acholeplasma laidlawii can be isolated from cattle environments and different body sites of bovines. It is still under evaluation if A. acts as a primary pathogen. Here, we present the whole-genome sequence conjunctiva heifer with infectious bovine keratoconjunctivitis.

Abstract The objective of this study was to compare nitrate concentrations in soil, forage, and the serum animals grazing high (HNO3) low (LNO3) forages. fall before began one-half a 6-ha field amended with manure increase levels soil. Forage barley (Hordeum vulgare L. var. Vernal) planted spring at 45 kg/ha. divided into twenty-seven 0.2-hectare paddocks (n = 13 HNO3; n =14 LNO3). Twenty-four ...

The objectives of the present study were to evaluate the effects of scrotal insulation on sperm production, semen quality, and testicular echotexture in Bos indicus and Bos indicus x Bos taurus crossbred bulls. In one experiment, B. indicus bulls (n=12) were allocated to control and whole-scrotum insulation groups, while in a second experiment, crossbred bulls (n=21) were allocated into control...

Breeding intact boars is a promising alternative to surgical castration of piglets. Genetic selection should enable farmers to solve problems due to boar taint and aggressiveness while taking into account potential consequences on other traits of interest. The aim of the study was to estimate genetic relations between sexual development, boar taint, health, and aggressiveness. About 1,600 Pietr...

There are numerous factors which need to be considered when selecting a bull to mate over heifers. In many cases, the primary aim of the beef producer is to produce a live calf which is born unassisted, with other economic traits (e.g. growth) of secondary importance. Traditionally this has been done by selecting a ‘heifer bull’ to mate over the heifers; that is, a bull with a low birth weight ...

A 14-month-old Japanese Black heifer presented with unilateral epistaxis and mild swelling of the right face. Radiography revealed a mass with increased radiopacity on the right side of the nasal bridge, extending to the left side. Intranasal endoscopy confirmed a large tumor-like structure protruding into the nasal cavity. Following euthanasia, cranial computed tomography (CT) was performed, r...

the study was carried out on 120 crossbred holstein × shahiwal dairy cows for a period of 150 days to quantify the influence of dietary energy and protein intake on yield and composition of milk. total 12 dairy farms having similar housing systems and holding at least 20 dairy cows in between mid to late lactation were selected for study purposes. the farms were located in the peri-urban and ur...
