Comparison of Sulla-hay and Sulla-silage in the lactating ewes and their effects on milk and cheese characteristics

2002

Abstract Two methods of storage of Sulla- and oat-grass (silage or hay) were compared. Forty-six homogeneous lactating ewes, housed indoors, were divided into two groups and after 35 days of diet adjustment, were fed ad libitum twice a day, either Sulla- ( Hedysarum coronarium L.) and oat-hay (control group) or Sulla- and oat-silage in partial substitution of hay (silage group). Both groups were fed with 0.5 kg of commercial concentrate. The dietary treatment started 60 days post-lambing and lasted for 58 days. Every day, the feeding intake for each group was recorded. Individual milk yield was measured weekly and at the same time, milk samples were collected and analysed by Milko-Scan 605.…

Silage of Prickly Pears (Opuntia spp.) Juice By-Products

2020

Simple Summary The cactus pear plant is a Cactaceae which originates from the Americas and is highly resistant to arid and hot environments. The plant is used as animal feedstuff in regions characterized by a lack of nutrient resources. In Italy, the fruits are known as prickly pears are usually eaten fresh by humans, and more recently have also started to be transformed into fruit juice. Various by-products (i.e., peel, pulp, and seeds) derived from the extraction of fruit juice are used for livestock feed due to their high amounts of fermentable structural carbohydrates. However, some of these by-products are difficult to conserve due to their high fermentability. The aim of the present s…

Switching spatial scale reveals dominance-dependent social foraging tactics in a wild primate.

2017

When foraging in a social group, individuals are faced with the choice of sampling their environment directly or exploiting the discoveries of others. The evolutionary dynamics of this trade-off have been explored mathematically through the producer-scrounger game, which has highlighted socially exploitative behaviours as a major potential cost of group living. However, our understanding of the tight interplay that can exist between social dominance and scrounging behaviour is limited. To date, only two theoretical studies have explored this relationship systematically, demonstrating that because scrounging requires joining a competitor at a resource, it should become exclusive to high-rank…

Biochar and Forage Peanut improve pastures: Evidence from a field experiment in Brazil

2023

Pasturelands, often degraded, represent most of the converted lands globally. It is important to understand how different pasture management approaches can improve soil quality, increase feed production and farmer income. Here, the impact of different soil enhancers on soil quality and productivity of three cultivars of Brachiaria (Syn. Urochloa) forage grass is presented. Soil enhancers included: biochar - a carbon-rich product from biomass pyrolysis, moinha (local charcoal residue), traditional fertiliser containing nitrogen, phosphorus and potassium, lime, and forage peanut (Arachis pintoi cv. Amarillo). Considering the total biomass produced over the experiment (sum of four harvests), t…

Itseään rukoilevat koneet : kirjaimellistuvat kielikuvat scifirunoa rakentamassa

2022

Tässä artikkelissa analysoin kolmea suomalaista scifiaiheista runoa. Runot ovat Markku Paasosen "Kone", Veera Antsalon "Play" ja Tomi Sonsterin "Tettiläinen". Jokainen tieteisfiktiivinen maailma on rakennettu novumin ympärille. Novum on jokin ilmiö tai keksintö, joka eroaa kirjoittajan omasta todellisuudesta ja joka on selitetty tieteellisesti. Carl Malmgrenin mukaan novumit voidaan nähdä ekstrapolatiivisina novumeina, jotka on tehty venyttämällä jokin asia tekijän omasta todellisuudesta, sekä spekulatiivisina novumeina, jotka tuovat lukijan keskelle täysin uusia todellisuuden lakeja. Nämä kaksi novumin päätyyppiä perustuvat runouden kielikuviin. Ekstrapolatiivinen novum perustuu metonymiaa…

Spider cues stimulate feeding, weight gain and survival of crickets

2014

1. To avoid predation, prey often change their behaviour upon encountering cues of predator presence. Such behavioural changes should enhance individual survival, but are likely to be energy-demanding. This should deplete energy reserves of the prey, unless it increases food intake. 2. These hypotheses were studied by conducting two microcosm experiments. In the first, crickets were kept on plants previously occupied by a spider or on control plants. After 3 days leaf consumption and weight gain of the crickets were quantified. In the second experiment, crickets were kept in the presence or absence of spider cues for 3 days. Spiders were then added and predation of the crickets was recorded…

Costs of courtship and mating in a sexually cannibalistic orb-web spider: female mating strategies and their consequences for males

2002

The costs of courtship and mating may include increased risks of predation, the transmission of pathogens, and a loss of foraging opportunities. Thus, a female's decision to tolerate a courting male will depend upon how these costs offset the benefits of mating, which will depend on her reproductive and nutritional status. While these costs may be similar for mated and unmated females, the benefits of mating will be less for mated than virgin females. However, the cost of lost foraging opportunities may be higher for females with fewer nutritional reserves necessary for forming eggs. We examined how these costs and benefits influence the courtship and mating behaviour of male and female orb…
