Theileria parva-naïve Friesian (Bos taurus), Boran (Bos indicus) and Maasai Zebu steers (B. indicus) were infected with a T. parva sporozoite stabilate dose which had previously been shown to induce an estimated 50% mortality rate in Boran cattle. All the cattle developed patent infections with no significant differences in the length of the prepatent period to development of macroschizonts (P ...

We found that sexual differentiation of all the nymphal stages of Pycnoscelus indicus (Fabricius) was possible by observing the developmental features of their posterior abdominal segments. Using this observation, the sex of even the 1st stage instar nymph could be determined. The female of the 1st to 6th stage instar nymph possess a V-shaped notch at the middle of the posterior edge of the 9th...

the present study investigates the effects of different routes of inulin administration as prebiotic on gut microbiota and survival rate of indian white shrimp post-larvae. four hundred and fifty indian white shrimp post-larvae (pl1) were stocked in nine tanks. the tanks were assigned into three treatments: feeding with inulin-treated (110 mg l-1) artemia nauplii (i-t), feeding with inulin-enri...

The effects of breed and of recombinant bovine somatotropin (rbST) treatment on growth hormone gene expression were studied in young bulls. The experiment was completely randomized in a [2 x 2]-factorial arrangement, using two levels of rbST (0 or 250 mg/animal/14 days), and two breed groups (Nelore and Simmental x Nelore crossbred). A cDNA encoding Bos indicus growth hormone was cloned and seq...

The aim of this study was to calculate the calving interval and reproductive efficiency by effect parity in a dual-purpose herd Mexican tropics. prospective observational cows´ records from year 2013 2021 analyzed. with pathology non 50% Bos indicus taurus were taken out. In total, 67 intervals between 24 cows gotten farm genotypes (Gyr) genes remaining came Holstein, Fleckvieh, Brown Swiss. A ...

genetic diversity of six populations of bartail flathead (platycephalus indicus linnaeus, 1758) was investigated using amplified fragment length polymorphism (aflp). a total of 118 reproducible bands amplified with ten aflp primer combinations were obtained from 42 fishes that were collected from six different locations in the northern part of the persian gulf. the percentage of polymorphic ban...

The bovine Growth Hormone gene (bGH) is an attractive candidate gene for milk production in cattle. Single-strand conformation polymorphisms at bGH were identified and used to define haplotype configurations at this gene in the Israeli Holstein dairy cattle population (Bos taurus) and in the parent animals of the International Bovine Reference Family Panel (a collection of B. taurus and B. indi...
