In the Neotropics the predominant pathway to intensify productivity is generally thought to be to convert grasslands to sown pastures, mostly in monoculture. This article examines how above-ground net primary productivity (ANPP) in semi-natural grasslands and sown pastures in Central America respond to rainfall by: (i) assessing the relationships between ANPP and accumulated rainfall and indices of rainfall distribution, (ii) evaluating the variability of ANPP between and within seasons, and (iii) estimating the temporal stability of ANPP.
In the present study an estimation of livestock enteric CH4 emission has been made from feeding systems (diets) for different animal functions (maintenance, production and growth) prevailing in different agroecological regions (AERs) of India using livestock population 2003. Estimations comprised of dietary intake, digestibility and CH4 emission factors for ruminant species of different age groups determined from feeding systems/diets. Methane production (ml g–1) from production diets in animal species tended to be more than growth and maintenance diets.
BASF said on Thursday it will undertake trial cultivation of potatoes containing genetically-modified organisms (GMOs) this year on less than one hectare on sites in Germany, Sweden and the Netherl
An international group of marine scientists is calling for cuts in commercial fishing for sardines, herring and other so-called forage fish whose use as food for fish farms is soaring.
After Portugal's driest February in 80 years, farmers are praying for a miracle as drought ravages pastures and sparks forest fires, exacerbating the country's economic crisis.
A group of 25 veterinary doctors and animal husbandry officers from Sri Lanka have begun a tour of Kerala to study the State's initiatives in dairy farming.
The delegation, led by Hiteki Saito, Chief Adviser, Feeding and Dairy Management, Department of Animal Production and Health, is scheduled to visit the high-tech farm established by the Kerala Livestock Development Board (KLDB) at Kulathupuzha.
This experiment was conducted to examine the effect of neem (Azadirachta indica) as an antibiotic growth promoter substitute on growth performance, carcass traits, and humoral immune responses in broiler chickens. A total of 192 one-d-old mixed sex broiler chicks (Ross 308) were weighted and randomly allocated to four treatment groups, each with 4 replicate pens of 12 chicks. The dietary treatments consisted of the basal diet (control), control+4.5 mg flavophospholipol/kg, or control+7 or 12 g neem fruit powder/kg.
Increasing population and consumption are placing unprecedented demands on agriculture and natural resources. Today, approximately a billion people are chronically malnourished while our agricultural systems are concurrently degrading land, water, biodiversity and climate on a global scale. To meet the world’s future food security and sustainability needs, food production must grow substantially while, at the same time, agriculture’s environmental footprint must shrink dramatically.
