Abstract:
... One of the objectives of the Animal Welfare Indicators project was to develop animal-based indicators to assess donkey welfare, including their emotional state. This study aimed to develop a fixed rating scale of Qualitative Behaviour Assessment (QBA) for donkeys, to evaluate the inter-observer reliability when applied on-farm, and to assess whether the QBA outcomes correlate to other welfare meas ...

Abstract:
... Turning preferences among 309 white-faced ewes were individually evaluated in an enclosed, artificially lit T-maze, followed by each ewe choosing either a right or left return alley to return to peers. Data recorded included time in the start box, time in the T-maze, exit arm chosen to leave the T-maze, and return alley. Right and left arms of the T-maze were chosen 65.7% and 34.3% of the time, re ...

Six geldings were equipped with continuous glucose monitoring systems and used in a crossover design over two 6-d periods. Diets consisted of free-choice prairie hay with either SF fed twice daily or free-choice access to a BL. ...

Abstract:
... The development and maintenance of a positive human–horse/donkey relationship is essential in order to decrease accidents and reduce negative states of equine welfare. In many animal species the reaction of animals to humans during specific behavioural tests is influenced by their past interaction and is linked to the level of fear felt in the presence of a human. The present research aims to asse ...

Abstract:
... Pair and social bonding has been documented in various taxa, where pair formations are often described as being driven by kinship or sexual motivation. However, pair-bonding between unrelated individuals where sexual motivation is not a factor is not well documented. Many social relationships and pair-bonds between members of a dyad are facilitated by each individual's ability to recognise their p ...

Abstract:
... In Beijing, China, females of Harmonia axyridis are promiscuous but prefer typical (succinea form) males to melanic ones in the spring generation, ostensibly due to the thermal disadvantages of melanism during summer. We used laboratory observations to test whether males invested differentially in females according to their elytral color, and whether male behavior was phenotype-dependent. Video-re ...

To investigate sterol composition during embryogenesis, the occurrence of 25 steroid compounds in stages of developing seeds and pods of Pisum sativum was examined by GC–MS analysis. Immature seeds containing very young embryos exhibited the greatest concentrations of sterols. Regression models indicated that the natural log ...

Abstract:
... Environmental factors like nutrient availability (e.g., C:N) and water deficit can influence secondary metabolites levels in plants and fungal endophytes. Locoweeds (Astragalus and Oxytropis spp.) contain swainsonine (SWA), an alkaloid that causes chronic vertebrate toxicity. In two greenhouse experiments, we studied field transplants of three Astragalus mollissimus varieties that vary in SWA leve ...

Southern root-knot nematode [RKN, Meloidogyne incognita (Kofoid & White) Chitwood], yellow nutsedge (YNS, Cyperus esculentus L.), and purple nutsedge (PNS, C. rotundus L.) occur together as a mutually beneficial pest complex in sandy soils. All crops grown in infested soils are affected due to the wide host range of the nematode, the perennial life cycle of the nutsedges, their interactions, and f ...

Weeds are alternative hosts for plant-parasitic nematodes and have long been recognized for their ability to maintain nematode populations targeted for suppression by various management strategies. The impact of weeds as alternative hosts depends largely on nematode feeding behavior, which is determined by the level of host specialization required for the parasite to feed successfully. In general, ...
