Developing integrated farming systems is critical to reducing the environmental impact of animal production. Traditionally, this has been through integrating animal and feed or plant production. But that has become increasingly difficult as agricultural production has become regionally specialized leading to the spatial separation of animal and feed production. This spatial separation has led t...

Proper nutritional status is critical for optimal production efficiency in the beef cow herd. However, beef producers often take a “one size fits all” approach to feeding the cows in the cow herd. This singular approach to nutrient supply for the cow herd can have serious nutritional and economic ramifications. It should be obvious that not all cows have the same nutrient requirements. Nutritio...

The present study was conducted to investigate whether dietary essential oils could affect growth performance, relative organ weights, cecal microflora, immune responses and blood profiles of broiler chickens fed on diets containing different nutrient densities. A total of eight hundred-forty 1-d-old male broiler chicks were randomly allotted into twenty-eight pens (7 pens per treatment, 30 chi...

This research aims to determine the nutritional content and best treatment for addition of Lemna sp. fermented growth sangkuriang catfish. The was conducted from February August 2022, in Aquaculture Laboratory Fisheries Marine Science Faculty, Universitas Padjadjaran. method used this is experimental, a Completely Randomized Design (CRD). It consists four treatments repetitions, namely A (contr...

We conducted 2 consecutive experiments to verify whether adult captive Greater rheas (Rhea americana) could select diets differing in nutritional and energetic content, and to evaluate the effect of those diets on egg production and hatchability. From August to January, animals were offered four diets: processed feed for rheas (diet 1), diet 1 + soybean (diet 2), processed feed for chicken (die...

We quantified groundwater discharge and associated nutrient fluxes to Monterey Bay, California, during the wet and dry seasons using excess (224)Ra as a tracer. Bioassay incubation experiments were conducted to document the response of bloom-forming phytoplankton to submarine groundwater discharge (SGD) input. Our data indicate that the high nutrient content (nitrate and silica) in groundwater ...

In economic terms, muscle is the most important tissue for pig producers. Research has been largely focused, therefore, on the means by which to increase carcass muscle content, as well as the efficiency of nutrient use for muscle growth. Since a major component in this tissue is protein, the rate at which protein is continuously synthesized and degraded, i.e. the rate of protein turnover, is r...

Feather keratin is highly resistant to degradation, but some keratinase producing microorganisms can easily degrade these insoluble keratins. These keratinase producing species have an important application in removal of poultry waste and recycled into valuable byproduct. Bacillus sp was screened from soil samples of slaughterhouse and poultry farm area using azokeratin medium. Highest keratina...

Evolutionary theory predicts that animals should forage to maximize their fitness, which in predators is traditionally assumed equivalent to maximizing energy intake rather than balancing the intake of specific nutrients. We restricted female predatory ground beetles (Anchomenus dorsalis) to one of a range of diets varying in lipid and protein content, and showed that total egg production peake...

The present study was undertaken to evaluate the effects of soybean varieties on content of anti-nutritional factors, growth, and nutrient digestibility in rat. For this purpose, the content of trypsin inhibitor and lectin was firstly measured in five soybean varieties. Then sixty male Wistar rats were randomly divided into six groups and fed on different diets as follows: groups 1 to 5 were fe...
