Judul: Reproductive Performance And Lambs Survival Of Prolific Sheep Withaddition Of Sunflower Oil (Helianthus Annus) As A Source Of Linoleic Acid
Abstrak: Garut sheep genetically is prolific, it gave birth two or more lambs, adaptability to environment. In fact the national productivity of local sheep still need to be improved. One of the efforts improvements that feeding strategy. Generally ration for livestock reproduction had calculated availability of macro nutrients such as protein and energy. Elements of micro minerals and vitamins that support the process of reproduction, however the availability of micro element such as essential fatty acids not yet to be considered and assessed extensively. The essential fatty acids such as linoleic isvery important in the diet, because the body can not synthesizes it. It can prepare with enrichment ration base on local feed with manipulation of fatty acid composition derived from sunflower oil (Helianthus annus Linn). This study has three main objectives: (1) toevaluate ration with different levels of sunflower oil on the reproductive performance of garut sheep, (2) to evaluate the increased levels of energy ration, with fat-rich unsaturated fatty acids from sunflower oil on the nutrient intake, rumen fermentability, performance and quality of ewes milk. and (3) to evaluate the performance pre-weaning lambs which were born from ewes fed rich linoleic diet. The experiment was conducted from May 2012 to February 2013, at Laboratory Analysis of Meat and Draught Animal Nutrition Science ,Faculty of Animal Science, Lab. Physiology and MicrobiologyLaboratory. Faculty of Veterinary Medicine and IPB Integrated Laboratory. The First study were used 32 ewes garut primaparous (initial body weight 22.12 ±1.69 kg), and 4 rams with the same fertility treatmentsconsisted of four ration with different levels of sunflower oil.Levels of sunflower oil were added based on the maintenance level of linoleic acid. M0=without sunflower oil, M1=2% sunflower oil, M2= 4% sunflower oil and M3=6% sunflower oil. Completely Randomized Design (CRD) was used in the study. Parameters measured werethe feed intake and digestibility of nutrients, reproductive parameters, the synthesis of the progesteronehormone, blood metabolites in different phases, andthe growth of ewes and lambs. Data were analyzed by ANOVA and Chi Square (χ2). Duncan test was used if significant difference. Some variables analysed descriptively, the relationship between variables was tested with simple regression. The first studyresults showed that the treatments did not significantly affect consumption of dry matter, protein and TDN, but significantly affect consumption of fat, linoleic acid and Beta-N (p<0.05).The treatments did not affect the digestibility of dry matter, crude protein, beta-N, calcium and phosphorus, but crude fiber and crude fat was significantly affected by the treatments (p<0.05). Levels of glucose, cholesterol,progesteron, the percentage of pregnancy, number of embryos. Litter size and the sex ratio of lambs was high significantly affected (p<0.01) by treatments. In the second study were Sixteen ewes 1.5 years old used, first lactation and caged individually with lambs. Experimental design using a completely randomized design with different replications.The treatments consisted ration with different levels of sunflower oil, i.e. R1= ration with 0% sunflower oil addition, R2= ration with 4% sunflower oil addition, R3=ration with 6% sunflower oil addition. The treatmentsof feed,were given before mating until weaning. The variables measured were dry matter intake, consumption of nutrients,

Abstrak: Garut ewes are small ruminants that have the prolific genetic potential to be developed as Good Farming Practice. The genetic potential must be supported by a good quality of feed. Sunflower seed oil which has advantages as a source of linoleic fatty acids that can improve reproductive efficiency. Behavior is one of the important aspects related to maintenance management and handling of livestock that need to know the effect of feed to animal welfare. The purpose of this research was to identify and evaluate the lamb behavior of garut after born with addition sun flower seed oils. The number of observation were 18 of sheep. Experiment research consists of TL0 (control), TL4 (4% addition of sunflower seed oil), and TL6 (6% addition of sunflower seed oil). This research used completely randomized design, the data were analyzed by ANOVA, and significantly different data using Tukey test. Parameter behavior measured were standing first time, suckling first time, suckling duration first time, suckling frequency, vocal frequency, laying frequency, standing frequency, moving of tail frequency, and scramble nipples especially for twins. The results showed standing and suckling first time, vocal, standing, moving of tail was significantly affect (P<0.05) on treatment. The addition of sunflower oil by 4% and 6% affected behavior of lamb garut after born
