Abstract

This study purposed is to determine the effect of thawing duration toward the quality of Brahman frozen semen. These include the motility of Spermatozoa, Spermatozoa concentration, Percentage of Spermatozoa Viability, Percentage of Spermatozoa Abnormalization and Individual Moitility, which was conducted at the UPTD Balai Artificial Insemination (BIB) Sembawa, Banyuasin District, South Sumatra Province. This research is experimental and carried out  a non-factorial complete random design analysis (CRD) consisting of 6 levels of treatment and 4 repetitions so that 24 unit experiments are be obtained, through variations in the treatment of 10, 20, 30, 40, 50, and 60 seconds, the length of time thawing. The effect of frozen thawing semen for Brahman Cattle has a very significant effect on Individual Motility and Percentage of Viability of Spermatozoa. Thawing time of 30 seconds on T3 treatment gives a very good influence on the quality of frozen semen of Brahman Cows, while on thawing time of 50 seconds on T5 treatment gives good quality on the percentage of spermatozoa abnormalities. The frozen semen spermatozoa concentration value of Brahman cattle is 53 x 106 Keywords: quality of frozen semen, thawing duration, Brahman cattle

Abstract

This study aims to determine the effect of the level of soursop leaf flour (Annona muricataLinn) in rations on internal organs in male laying hens (Gallus domesticus). The research method used was an experimental method using a Complete Randomized Design (CRD) arranged nonfactorial, with 6 levels of treatment 4 replications so that 24 experimental units were obtained, each experimental unit (each cage) was filled with 4 male laying hens.  So in this study required 96 male-and-male (DOC) eggs. The treatments in this study were: U0 = Commercial Feed BR-1, U1 = 100% Commercial Feed without Soursop Leaf Flour, U2 = Commercial Feed 98% + Soursop Leaf Flour 2%, U3 = Commercial Feed 96% + Soursop Leaf Flour 4% , U4 = Commercial Feed 94% + Soursop Leaf Powder 6%, U5 = Commercial Feed 92% + Soursop Leaf Powder 8%. From the results of statistical data analysis it is known that the treatment of soursop leaf flour in rations on organs in Male Laying Hens has a significant effect on heart weight, but does not significantly affect heart weight, pancreatic weight and gizard weight.

Abstract

he purpose of this study was to see the success rate of Artificial Insemination on beef cattle  in Purwodadi district, Musi Rawas Regency. The parameters observed is Service per Conception (S/C), Conception Rate (CR), Non Raturn Rate (NRR) and Calving Interval (CI).  Survey method isused  in this study by taking all area of Purwodadi district as the observed area because of its livestock population then analysed by using Slovin Formula to obtain 93 samples. The results of this study concluded that the Conseption Rate (C/R) in Purwodadi District was very good because it was obtained 70.96%. Figures for   S/C in Purwodadi sub-district showed an average of 1.4. As for the NRR value in Purwodadi Subdistrict, NRR(0-30) obtained a percentage of 70.96%. NRR(31-60) obtained 93.54% and NRR(61-90) obtained 100%. The value of the Calving Interval (CI) is very good, reaching an average of 14.7 or 14 months 7 days.Keywords: Artificial insemination, Purwodadi district, Beef Cattle, Success Rates
