Poultry Management during Winter (Cold)

  Winter season has great effect on poultry production by lowering the temperature of surrounding. During winter when temperature goes down below 55ºF, various problems like reduction egg production, reduction in water intake, reduction in fertility and hatchability etc occurs. Therefore the management of poultry during winter is an important concern for poultry farmers. The following points should be considered to get better production from poultry during winter season: Orientation of house Ventilation Litter Management Feed Management Water Management 1.Orientation of House Poultry house should be designed in such a…

Crunch time for food security

Feelings often run high where insects are concerned, with many people even squeamish to look on them, let alone touch or swallow them. And yet insects present a huge nutritional opportunity as an increasing global population seeks sustainable sources of food and feed. Insects have generally high levels of animal protein and key micronutrients with lower environmental footprints than traditional alternatives, and they can be raised on leftovers. But cultural, social and economic hurdles remain, reports a review paper published today in Nutrition Bulletin. “Insects present a nutritional opportunity, but…

Pesticides may cause bumble bees to lose their buzz, study finds

Pesticides significantly reduce the number of pollen grains a bumblebee is able to collect, a new University of Stirling study has found. The research, conducted by a team in the Faculty of Natural Sciences, found that field-realistic doses of a neonicotinoid pesticide affects the behaviour of bees ultimately interfering with the type of vibrations they produce while collecting pollen. Dr Penelope Whitehorn, the University of Stirling Research Fellow who led the research, said: “Our result is the first to demonstrate quantitative changes in the type of buzzes produced by bees…

Credit: Image courtesy of Kobe University The mysterious flowers of Aspidistra elatior are found on the southern Japanese island of Kuroshima. Until recently, scientists thought that A. elatior has the most unusual pollination ecology among all flowering plants, being pollinated by slugs and amphipods. However, direct observation of their ecosystem has revealed that they are mainly pollinated by fungus gnats, probably thanks to their resemblance to mushrooms. This discovery was made by Project Associate Professor SUETSUGU Kenji (Kobe University Graduate School of…

How to keep cows happy

Brazilian study shows how small changes on farms can lower stress levels of cattle   Story Source: Materials provided by Springer. Corrals are used on livestock farms around the world to round up the animals when they need to be weighed or vaccinated. New research now shows that removing splashes of colors, shadows or water puddles from corrals, keeping noise levels down and not using dogs and electric prods can dramatically reduce the stress cattle experience. Maria Lúcia Pereira Lima of the Instituto de Zootecnia Sertãozinho in Brazil is the…

HOW TO IMPROVE FERTILE EGG SURVIVAL RATE

HOW TO IMPROVE FERTILE EGG SURVIVAL RATE

Fertilization marks the beginning of a new life but is by no means a guarantee of a long one, as the journey is full of obstacles. Stress, genetic factors, diseases or nutritional deficiencies may all kill the embryo before the egg is laid. The newly laid egg is then exposed to another set of risks: the conditions under which it cools down from the hen’s body temperature to the ambient conditions in the nest, the time this takes, mechanical factors, chemicals, infections and even disinfection are all hurdles to overcome.…

Where a leaf lands and lies influences carbon levels in soil for years to come

Detailed shot of a soil horizon studied to examine litter decay. Credit: Image courtesy of John Bryan Curtis In one of the few such studies, scientists examined how dead leaves, roots, and other plant litter decay over a decade. The team used stable isotope labels to trace plant litter-derived carbon and nitrogen as the litter decomposed and formed soil, specifically the fraction of soil called organic matter, which comes from plant inputs and microscopic animals. They found that the litter type (needles or roots) and the placement in the soil…

Discovery of 8,000-year-old wine production in ancient Middle East

Archaeologists find earliest evidence of wine-making This is base of Neolithic jar being prepared for sampling for residue analysis. Credit: Judyta Olszewski Excavations in the Republic of Georgia by the Gadachrili Gora Regional Archaeological Project Expedition (GRAPE), a joint undertaking between the University of Toronto (U of T) and the Georgian National Museum, have uncovered evidence of the earliest wine making anywhere in the world. The discovery dates the origin of the practice to the Neolithic period around 6000 BC, pushing it back 600-1,000 years from the previously accepted date.…

Steps to Combat Heat Stress in Birds

The aim of adopting measures to combat heat stress is not only to keep birds alive but also to get production out of them to achieve targeted figures i.e. number of egg from layers and a better body weight at particular age with specific FCR in broilers. The following steps will help to combat heat stress in birds: Housing Management Water Management Feed Management General Management 1.Housing Management a) Orient the long axis of poultry house in an east-west direction to minimize solar heating and directed access to sunlight. b)…
