Abstract

The objective of the experiment was conducted to evaluate the effect of feeding bypass fat on haematological, growth and reproductive parameters on Jaffrabadi buffaloes (twenty four) in their 1-4 lactation. They were randomly selected and divided into four group of six each for 183 days. Twenty four Jaffrabadi buffaloes were divided into four groups of equal number: Control group (T1), Bypass fat @ 10g/lt. milk yield (T2), Bypass fat @ 20g/lt. milk yield (T3) and Bypass fat @ 30g/lt. milk yield (T4). Blood samples were collected on the 1st and 183rd day of the trail. A close examination of the nutritive effects of different levels of bypass fat (MAGNAPAC) supplementation on haematological values in the blood (white blood cell count (WBC), red blood cell count (RBC), hemoglobin (Hb) and pack cell volume (PCV) was carried out. Body weight and reproductive parameters like service period, conception rate and post partum estrus were consideration in this experiment. No significant differences were found between treatments in haematological values and in growth of animals. But due to these treatments required about 16 -27% less service per conception, observed shorter service period than control group. Bypass fat have no effect on haematological and growth parameters but it helped to improve the reproductive performance especially in post partum in Jaffrabadi buffaloes.

Abstract

Eighteen Gir cows of similar body weight and stage of lactation were randomized into three groups of six each and were offered one of the dietary treatments (T1: Green jowar@5 kg per day per animal and ad lib feeding of wheat straw, T2: Green jowar and wheat straw mixed in the ratio of 30:70 offered ad libitum and T3 : 4% urea treated wheat straw offered ad libitum) along with concentrate mixture to meet protein requirement for a period of 70 days. Body weight losses in experimental cows in all the groups were non-significant. T2 group cows produced significantly (p<0.01) higher milk and FCM yield and also consumed higher DMI with narrow R:C ratio than control and T3 group of cows. However, cost of feeding was significantly ( p<0.01) lower in urea treated wheat straw offered group of cows compared to control with 135 per cent higher return over feed cost.

Abstract

The prostaglandin and its synthetic analogue are considered as drug of choice in reproductive management. A total of twenty Jaffrabadi buffaloes with reproductive disorders were selected from cattle breeding farm, Junagadh. All twenty buffaloes (Group I) were treated with single dose of Prostaglandin (synthetic analogue, clostrinol, 2 ml) while the animals which did not respond (Group II) to first injection of Prostaglandin were subjected to second injection of Prostaglandin 11 days after first treatment. A total of six animals (30%) responded to first dose of PGF₂α, while eight animals (57%) responded to second dose of PGF₂α. The mean time required for induction of heat in first and second group was 70.24 ± 1.44 hrs and 56.86 ± 1.96. The mean duration of estrus proper in first group was 19.18 ± 0.69 hrs, while in second group the mean duration was 16.13 ± 0.42 hr. The conception rate in the present study was 43.05 per cent for the first group of animals and 49 per cent for the animal that were treated with second dose of PGF₂α. In conclusion, administration of PGF₂α at eleven days interval causes faster heat induction and better conception rate.

Abstract

The Chrysoperla species (carnea-group) widely used in India in augmentative biological control programmes was found to be Chrysoperla zastrowi arabica Henry et al. The acoustic profile of the mating song of this species was analyzed and found to match that of C. zastrowi arabica, the song species characterized earlier as 'Cc5 generator'. The correct taxonomic name for this species remains to be determined as it is morphologically identical to C. sillemi (Esben-Petersen), a species already known from India. Molecular characterization of the species was also done and the DNA sequence of the ITS-2 region was deposited in GenBank (Accession No. DQ 825504, as that of C. sillemi). The implications of this finding are discussed.

Abstract

Preliminary investigations were conducted in laboratory cages to test the efficiency of a novel release technique for egg parasitoid Trichogramma species and this was compared with the traditional techniques. The efficiency of the techniques was determined based on time taken for release, adult emergence and percentage egg parasitism. Mixing of eggs with carriers like talc (1:1 ratio) and agar solution (0.1%) recorded least time for application. Spraying of loose parasitised eggs mixed with agar solution was considered as the best treatment amongst the treatments where aqueous solutions were used as carriers. In treatments where loose parasitised eggs were mixed with various solid and aqueous carriers, per cent emergence was low ranging from 40.5 to 57.1% compared to 95.0 to 100.0% in release of adults, Tricho bit, Tricho capsules and loose eggs without any carrier. The lowest emergence was recorded when loose parasitised eggs were mixed with talc. Adult release, sprinkling of loose parasitised eggs mixed with vermiculite and semolina gave significantly higher parasitism compared to the other techniques of release. The results indicated that release of Trichogramma can also be tried by mixing with a spray solution (for eg. agar solution) with modification of sprayer nozzle or with solid carriers (for eg. vermiculite). Such techniques will be better understood by stakeholders and is expected to increase uptake of this important biological control agent.
