Studies in India from the early to late 1990s found that rural youths and women played a predominant role in livestock farming. Even though many studies differ in the extent and nature of the contribution of youths and women in livestock farming, all acknowledge their roles and contribution. Livestock farming acts as a source of supplementary income to youths and women and provides increased nutritional security. New economic policies of the1990s have brought changes to the livestock farming community. This paper attempts to understand and describe the role of women and youths in livestock farming. The research methodology employed for the present study is ex post facto design, and includes semi-structured open-ended interviews, observation and conversations with key informants. The study has found that a change in the roles of women and the participation of youths in livestock farming has occurred, which could be detrimental to the well-being of rural family farmers.

Chemo-signals are among the reliable non-invasive methods for estrus detection in mammals. Water buffalo is a silent heat animal and, hence, there is search for chemo-signals which would be effective non-invasive indicators of estrus state. We analyzed the faecal chemical cues during the estrous cycle in buffalo and to find the estrus-specific faecal volatile compounds adopting bull behavior assay. The faecal samples were collected at three phases of the estrous cycle (i.e., proestrus, estrus and postestrus) and subjected to gas chromatography-mass spectrometry analyses. We found 27 volatile compounds in the faeces of buffaloes, of which 4-methyl phenol (4mp) and trans-verbenol (tv) were found only in estrus faeces. The faecal samples of estrus buffaloes and the estrus-specific compound(s) (4mp+tv) at three different concentrations were tested for behavioral responses (flehmen and mounting behavior) in the bull. The bulls exhibited repeated flehmen when exposed to a combination of the two compounds (i.e., 4mp+tv) as compared to the individual compounds or raw faecal sample collected from buffalo when in estrus (P<0.05). However, higher number of mounting behavior was recorded when bulls were exposed to 4mp followed by a combination of the two compounds (4mp+tv) and trans-verbenol (P<0.05), in that order. By contrast, less number of mounting behavior was exhibited by bulls when exposed to the control sample (i.e., Hexadecanoic acid) (P<0.05). As inferred from the bull behavior assay, the present study suggests that the two compounds, 4 methyl phenol and trans-verbenol would be reliable indicators of estrus in buffaloes. © 2013 Elsevier B.V.

During the present survey, 20 buffalo calves were examined for lice infestation at a private buffalo farm, situated in Lathuwadi, Namakkal, Tamil Nadu, India. One hundred percent of the buffalo calves were infested with Haematopinus spp. Clinical signs included of alopecia, pruritis, small crusts and scabs. Lesions were confined to the neck, shoulders and rump. Skin scrapings were examined and eggs, larva, nymphs and adult mites were recovered. The relationship between sex and age of animal was also determined; it was 94.1% in females for Haematopinus spp., while in males it was 80 percent. It was significantly (P<0.05) higher in age group of more than six months as compared to 14.2% in lesser than six months old. Source
