Understanding the unique traits of indigenous pigs which make them resilient to climate change and development of data base

 

   

 

 

Adaptation and mitigation strategies in poultry to thermal stress

The performance of various breeds of pig in different housing models was tested under Meghalaya conditions. The study revealed that the growth rate in deep litter housing was better and there was lower incidence of diseases and occurrence of other abnormal behavior.

Development of threshold levels of climate variables for incidence of livestock diseases

 


Spatio-temporal epidemiological (outbreaks, diagnosed cases and death cases) data (2002-14) analysis of eight livestock diseases in Tamil Nadu state revealed Anthrax (109) was high followed by Foot and mouth disease [FMD] (99), Peste des petits ruminants [PPR] (45), Bluetongue [BT] (44), Black quarter [BQ] (34), Haemorrhagic septicemia [HS] (15), Sheep and Goat pox (15) and Enterotoxaemia [ET] (9).

Supplementation of methionine isomers (DL methionine, MHA Ca and L methionine) in commercial broiler chicken maintained on floor pens (6.6 x 4 feet) containing 22 commercial broilers in each pen during tropical summer (max temp 34.70C+1.07; min temp 26.30C+1.16; max humidity 69.0%+4.82; min humidity 33.6+6.01%) improved the body weight gain, feed efficiency and breast weight of the birds. Increase was more in DL methionine group followed by L methionine and MHA in that order.

Adaptive management of small ruminants under grazing conditions to climate change

 

A study is in progress to identify the physiological indicators of stress in grazing small ruminants and to develop consolidated adaptation strategies under grazing conditions. Thirty six Nellore ewes (22.8 ± 2.86 kg) were randomly divided into two comparable groups with eighteen animals in each group and exposed to heat stress during April to June by allowing for grazing for 6 hrs (0800-1200hrs and 1600-1800hrs).
