Sapera goats, a crossbreed between Saanen and Etawa Grade are known for their milk pro-duction adaptability to the Indonesian climate. Genetic selection is necessary improve Sa-pera goat's quality quantity. CSN2 gene one of genes that can affect composition goat milk. Therefore, this study aimed identify mutation points (SNPs) at exon 7 its association with composition. This used sixty-six bloo...

A series of studies were conducted to determine the effect of supplemental trace mineral source on growth performance, morbidity, and trace mineral status in growing beef cattle. The first experiment evaluated supplemental trace minerals from sulfate, organic, or hydroxy sources on growth performance and morbidity. Crossbreed beef calves were assigned to 1 of 3 treatments consisting of suppleme...

introduction one of the animal breeding aims is increasing the economic efficiency. therefore, mating among selected animals in order to enhance economic efficiency should also supply variation in population for next generations’ selection. this study was performed to estimate performance in cross breed lambs resulting from crosses of shal, moghani, afshari and varamini rams with varamini ewes,...

The objective of this study was to determine the efficacy separating X- and Y-sperm using nano-albumen (NA). material used in fresh semen Ongole Crossbreed bulls with progressive motility ≥ 70%. Treatments for top bottom fractions were T0 (BSA 5% : 10%) as a control, T1 (NA 2% 4%), T2 4% 6%), T3 6% 8%). Sexed evaluated characteristics kinematics, proportions sexed validated morphometric polymer...

DOMESTIC BUFFALOES ARE DIVIDED INTO TWO GROUP BASED ON CYTOGENETIC CHARACTERISTICS AND HABITATS: the "river buffaloes" with 2n = 50 and the "swamp buffaloes", 2n = 48. Nevertheless, their hybrids are viable, fertile and identified by a 2n = 49. In order to have a better characterization of these different cytotypes of buffaloes, and considering that NOR-bearing chromosomes are involved in the r...

Abstract The study aimed to examine the meat quality of chickens from a dual-purpose cross and its parent lines. trial was conducted in experimental poultry farm Institute Animal Science-Kostinbrod, Bulgaria. were obtained by crossing female layers (Line L) cocks (BB, based on Bresse Gauloise). At age 9 weeks male lines slaughtered. Six each genotype subjected breast thigh analysis. crossbred t...
