Grading Index(GI)∶A New Integrated Technique for Evaluation of Forage Quality

IntroductionForage quality can be defined as the extent to which forage has the potential to produce a desired animal response or level of performance,for example,daily gain or milk production.Due to forage quality is a function of both animal and plant factors.It is difficult and complex to completely evaluate forage quality.Recently,an new integrated index,Grading index (GI),was proposed by Chinese scholar Lu Dexun.Grading index (GI) method has been appraised officially as the national standard of forage quality evaluation in China,which was implemented in 2009.On basis of briefly overview the development of forage quality evaluation technology,this paper is to emphasize on introducing forage grading index and its application in dairy cattle feeding.     

GMOs in animal agriculture: time to consider both costs and benefits in regulatory evaluations

In 2012, genetically engineered （GE） crops were grown by 17.3 million farmers on over 170 million hectares. Over 70% of harvested GE biomass is fed to food producing animals, making them the major consumers of GE crops for the past 15 plus years. Prior to commercialization, GE crops go through an extensive regulatory evaluation. Over one hundred regulatory submissions have shown compositional equivalence, and comparable levels of safety, between GE crops and their conventional counterparts. One component of regulatory compliance is whole GE food/feed animal feeding studies. Both regulatory studies and independent peer-reviewed studies have shown that GE crops can be safely used in animal feed, and rDNA fragments have never been detected in products （e.g. milk, meat, eggs） derived from animals that consumed GE feed. Despite the fact that the scientific weight of evidence from these hundreds of studies have not revealed unique risks associated with GE feed, some groups are calling for more animal feeding studies, including long-term rodent studies and studies in target livestock species for the approval of GE crops. It is an opportune time to review the results of such studies as have been done to date to evaluate the value of the additional information obtained. Requiring long-term and target animal feeding studies would sharply increase regulatory compliance costs and prolong the regulatory process associated with the commercialization of GE crops. Such costs may impede the development of feed crops with enhanced nutritional characteristics and durability, particularly in the local varieties in small and poor developing countries. More generally it is time for regulatory evaluations to more explicitly consider both the reasonable and unique risks and benefits associated with the use of both GE plants and animals in agricultural systems, and weigh them against those associated with existing systems, and those of regulatory inaction. This would represent a shift away from a GE evaluation process that currently focuses only on risk assessment and identifying ever diminishing marginal hazards, to a regulatory approach that more objectively evaluates and communicates the likely impact of approving a new GE plant or animal on agricultural production systems.     

4 ＂100%＂ Aims of Feed Quality Realized in 2008

The four ＂100%＂ aims ty control work have been set for feed quality safefully achieved in 2008, thanks to the swift action, powerful measure, and comprehensive work of the animal husbandry and feed administrations at all levels, the journalist understood at the protein feed ingredients supervision work conference on January 22, 2009.

PREFACE

<正>Reproduction is essential for the health and well-being of humans,livestock,companion animals,and wildlife populations.Regarding animal agriculture,reproductive efficiency is a major limitation in many cases to economic success of the livestock enterprise.This is due to high rates of embryonic mortality and intra-uterine growth restriction that reduce reproductive efficiency and production of health offspring in humans and animals.A high level of reproductive performance for livestock species reduces the impact of animal agriculture on the     

Grassland quality response to climate change in Xinjiang and predicted future trends北大核心CSCD

Grassland is a major vegetation type in Xinjiang Province,and is an important component of carbon source-sink calculations. It is therefore important to ecological management decisions to understand the factors driving changes in grassland quality and likely future trends in those changes. We used geographic information maps to eliminate the interference of human activities and determine changes in grassland status and areas of stable grassland from 1980 to 2020,and analyzed changes in grassland quality and its response to climate change using data such as normalized vegetation index（NDVI）,vegetation net primary productivity（NPP）,and meteorological data,among others. We here estimate changes in grassland quality in Xinjiang and predict grassland quality changes from 2021 to 2040 using the Thornthwaite Memorial model and other models. We found that：1） The grassland quality in Xinjiang was generally increasing,with a statistically significant rate of ongoing increase. The grassland cover and quality in mountainous areas of Xinjiang was high,while that at the desert edge was low. 2）The main driving forces for grassland quality changes in Xinjiang are temperature and precipitation. The correlation between grassland quality and precipitation was positive. Temperatures exceeding a certain limit were found to inhibit grassland quality. Sensitivity to temperature and precipitation decline was found to be greater when vegetation cover was lower. 3）The grassland quality and its temporal and spatial changes in Xinjiang can be reflected by climatic productivity. The lower the grassland cover,the stronger was the link between grassland quality and climate factors. 4）Under currently predicted climate change scenarios,the quality of low-cover grassland will be improved in the future,while the quality of other categories will tend to decrease. This information on grassland quality in Xinjiang and its predicted future trends can assist in formulating ecological protection measures and in other ways,such as compilation of carbon stock inventories. © 2022 Editorial Office of Acta Prataculturae Sinica.
