Mammary gland differential growth during pregnancy in superovulated Javanese thin-tail ewes

Abstract Twenty-one pregnant ewes (12 non-superovulated and nine superovulated prior to mating) were used to study the effect of superovulation on mammary gland differential growth at weeks 7 and 15 of pregnancy. The experimental ewes were slaughtered at the respective stage of pregnancy and the mammary glands were excised to determine mammary gland growth and development by measuring mammary dry fat-free tissue (DFFT), mammary DNA, RNA, collagen, protein and glycogen. In the ewes slaughtered at Week 7 of pregnancy, superovulation increased (p

Haematological study of fruit bat, Cynopterus Tithaecheilus

Haematological profile is important to determine the physiological condition of an individual, and morphology of red blood cells can also be helpful in making a diagnosis of a disease. The size of red blood cells affects the ability of red blood cells to carry oxygen. In some clinical events shape and size of red blood cells will be changed. Bats are the only mammals that have the ability to fly. The ability of bats to fly would require bats to be able to bind more oxygen, therefor bat should have enough of energy while flying. The present study was conducted on 12 Cynopterus tithaecheilus (7 males and 5 females) to study about haematological profile. Blood samples were taken using tuberculin needle and analyzed by hematology analyzer for hematological value. Size of red blood cells was taken using bloods smear and analyzed by imageJ software. Cynopterus tithaecheilus show the higher number of red blood cells, but the size were smaller compared to the other mammals which has same body size. Mean while the concentration of hemoglobin and hematocrit were higher. The present result suggested that these haematological values might provide a greater transport oxygen capacity in the Cynopterus tithaecheilus.

Bats As A Viral Reservoir: A Short Review Of Their Ecological Characters And Immune System

Bats are reported as natural reservoir host of several viruses, many of which cause severe human disease. Infected bats usually do not show any clinical symptoms and persistently infected. Bats immunity against viruses is an evolutional process of self-defense created by ecological adaptation between host and pathogen. Bats have unique characters which support them as a viral reservoir, whereas RNA viruses which are commonly carried by bats take an advantage of these characteristics to survive. The role of bats as reservoirs is also supported by several differences of immune system than other mammals. Several studies on molecular factors of bats immune system lead to a hypothesis that bats are able to control viral replication very early in the immune response through innate antiviral mechanism. However, to complete understanding of the nature of immune responses of bats to the virus still needs a lot of study. Advance technology on molecular techniques revealed the immune factors and provided numerous data about molecular factors in bat immunity, however comprehensive studies about morphology of bats immune organs are still lacking. One of the important immune organs which have functional variations due to their structural differences between species is the spleen, which will be our main focus of study in the future. We hope that the result of our study will be able to provide the database on the morphology and physiology of bat spleen and give better understanding on bats immune system.

Pengaruh Suplementasi Minyak Ikan Lemuru Terhadap Status Kesehatan Ayam Petelur yang Diimunisasi Berulang

The experiment was carried out to observe the effect of adding lemuru fish oil in immunized laying hens diet on the health status of chicken through leucocyte profile, stress index, erythrocyte profile, and malonildehyde concentration in liver and spleen. The research design was completely randomized and the obtained data was analized with analysis of variance and continued with Tukey’s Post Hoc test for differences. The experiment used thirty 18 weeks hens ISA brown strain and were divided into five groups. The groups were: A (immunization with lipase and control diet); B (immunization with lipase, control diet + 1% lemuru fish oil); C (immunization with lipase, control diet + 2% lemuru fish oil); D (immunization with lipase, control diet + 3% lemuru fish oil); and E (unimmunized and control diet). The immunization was repeated three times with four weeks interval, blood was collected and analyzed two weeks after immunization and the malonyldehyde concentration in liver and spleen was measured two weeks after third immunization. The results showed that there was no significant difference (P>0.05) on all variables. The conclusion of this research that lemuru fish oil supplementation did not affect the health status of immunized hens.
