Abstract

Protein has the role in the development of physiological structure and body immunity system. Reproductive hormones, gametogenesis and fetus development are very much affected by the content of protein, vitamin A and E. Vitamin A is known to have a role in the integrity of epithel tissue, thus it has a great effect on the process of gametogenesis and embryogenesis. Vitamin E is recognized as an anti-sterility vitamin because of its important role as an intercellular antioxidant, in absorbing and storing vitamin A. This research was intended to determine the effect of protein content (15%, 18% and 21%), vitamin A (2000 IU/kg of feed), and vitamin E (30 mg/kg of feed) on body weight and some characteristics of reproduction of white mice (Rattus novergicus). The reproduction characteristics observed on female were the litter size and their body weight at birth, whereas those on male were fertility and morphology of spermatozoa. The research results showed that there were some effects of protein, vitamin A and E on increased body weight of female. The best result with a significant change (P

Abstract

The objective of the experiment was to study the characteristics of stallion fresh semen and the quality of sperm preserved in Dimitropoulos extender (DV) supplemented with different concentration of fructose, trehalose and raffinose. Semen were collected using artificial vagina from three stallions. Semen characteristics and quality were evaluated macro- and microscopically. Prior to extension, semen were centrifugated at 3000 rpm for 20 minutes. The condensed sperm were re-suspended in DV supplemented with different types of carbohydrate to meet the concentration of 200 million spz/ml. All samples were stored at room and chilled temperature, and were evaluated for motility and viability every 3 h and 12 h. The results of the experiments indicated that fresh semen characteristics were fair good; the volume, consistency, motility, live-dead ratio, concentration (106/ml), total spermatozoa (109/ejaculate) and abnormality were 29.25±9.33 ml, watery, 7.00±0.12, 67.08±9.08%, 77.89±6.46%, 211.88±21.15, 6.28±2.45 and 27.26±4.64%, respectively. The supplementation of different type and concentration of carbohydrates did not significantly affect the motility and viability. However, the supplementation of 50 mM fructose significantly increased the motility and viability of the sperm compared to the control. In conclusion, carbohydrate supplementation in DV may not maintain the sperm quality, particularly in the medium with the osmolarity higher than 400 mOsm/kg.

Abstract

This study was to evaluate the depolarization of katuk leaves (Katuk-IPB3) as a feed additive for increasing dairy cattle milk yield at the farmer condition. Sixteen selected lactating cattles were divided into 4 groups; 4 cattles in each group. One group as a control, and 3 treated groups, namely P100, P150, and P200. P100, P200, and P300 were designated as cattle group given powder of Katuk-IPB3 as much as 100 g/day, 150 g/day, and 200 g/day, respectively. The treatment was executed in the 10 days before pregnancy up to 2 months lactating periods. Katuk-IPB3 showed significant positive response on the produced milk on all dose levels as compared to the control group, i.e. 35, 40, and 34% increased, respectively. The possible reason is that the nonpolar active compounds in the Katuk-IPB3 play an important role to the hormonal and metabolic action in the lactating mammary gland.
