It comprises the major protein supply for milk production. The demand of milk is increasing for nutrition of population in country. Presently, Azolla green fodder feeding is being considered essential for lactating dairy animals. Azolla is nothing but floating fern in shallow water, which is very rich in protein, essential amino acids, and vitamins. Azolla can be easily digested by the dairy animal because of its high protein and low lignin content, green Azolla can be used as feed supplement for the milch animals (500-1000gm per day) which could increase the milk production by 7-13%. The front line demonstration of Azolla cultivation in the programm area could bring changes in feeding management of dairy cattle.ArticleItem Open Access Four Different Therapeutic Regimens for Management of Repeat Breeder Dairy Cattle in Theni District of Tamilnadu(Cloud Publications, 2014-10) Senthil Kumar, A; Sri Balaji, N; Shanmugasundram, A; TANUVASThe objective of this study was to evaluate the efficacy of four different treatment regimens for repeat breeder dairy cattle with antibiotic and hormonal. The study was conducted in 50 apparently healthy crossbred repeat breeding dairy cows and divided in to five groups with 10 animals each. Animals of group 1 were administered 2 ml of hydroxyl progesterone i/m administered on 4th day of estrum after 1st insemination. Animal in group 2, were administered 60 ml of diluted cephalixen intra uternally immediately after the first time artificial insemination. Animals in group 3 and 4 were administered i/m 1500 IU human chronic gonadotrophin and i/m 10 mg GnRH analogue respectively, immediately after first insemination. All the 5 groups’ animals were re-inseminated at interval of 12 hrs after the first insemination. The group 5 animals were inseminated without any hormone or antibiotic therapy and were kept as control for the various treatments. Pregnancy diagnosis was carried out in all groups at 60 days after AI by per rectal examination. Analysis of data showed that there was a significant lower in duration of estrum in the treatment compared to control group except group 2. The conception rate in groups 1 to 5 was 40; 40; 50; 30 and 30 per cent respectively. A maximum of 50 per cent conception rate was observed in group 3 repeat breeder dairy cows. All groups were re-inseminated at 12 hrs interval for increasing the conception rate in repeat breeder dairy cows with prolonged oestrum.
