Supplementation of Coenzyme Ubiquinone (COQ10) in the semen diluent of Balitbangtan’s Superior Native Chicken in Terms of Spermatozoa Cromatin Damage

/in /by

The development of technology in the field of animal husbandry is growing very rapidly, apart from ruminants from poultry livestock can also be done artificial insemination used for breeding. According to Apriyanti (2017) The success of the mating system can be seen from the success of livestock mating which is influenced by the quality of the semen produced. One of the supplementations used is coenzyme ubiquinone (CoQ10) where CoQ10 is one of the vitamins such as fat-soluble vitamin E which is endogenously present in the inner membrane of mitochondria of mammals and plants (El-Sayed, et al. 2021). This study used an experimental method or field experiment with 4 treatments and 10 replicates on 4 male KUB chickens aged 12 months and the diluent used was egg yolk lactated ringer. The variables observed in this study wes cromatin damage of spermatozoa before freezing and post thawing. The results obtained in this study chromatin damage before freezing obtained the highest average value of 1.18 ± 0.58 with statistical calculations showed significantly different results (P < 0.05). chromatin damage after thawing back obtained the highest result of 2.80 ± 0.89 with statistical test calculations obtained results that were not significantly different (P < 0.01) to the different levels of Coenzyme ubiquinone in diluents with different levels.

Supplementation of Trace Minerals and Nuleotides in Concentrate Containing Moringa Leaf Flour on Consumption and Nutritional Digestibility of Pregnant Goats

This study aims to evaluate trace mineral and nucleotide supplementation in concentrate feed containing Moringa leaf flour on the consumption and nutritional digestibility of late pregnant goats. This research was carried out at the Feed Chemistry Laboratory and Field Laboratory, Faculty of Animal Husbandry, Marine Fisheries, Undana for 3 months. The livestock used in this research as test material for the use of concentrate feed containing Moringa leaf flour supplemented with trace minerals and nucleotides were late pregnant goat mothers aged 8 months – 1 year. This research used an experimental method with a 4×3 randomized block design, namely 4 weight groups and each was repeated 4 times. There were also treatments in this study as follows: R0: pregnant mother goats were given field grass forage (control), R1: R0+Concentrate containing Moringa leaf flour, R2: R1+supplementation of 100 mg of trace minerals and nucleotides in 1 kg of concentrate based on dry matter, R3 : R1+ supplementation of 150 mg trace minerals and nucleotides in 1 kg concentrate on a dry matter basis. Feeding is based on the dry matter requirements of ruminants, namely 3.5% of body weight, with a balance of 70% natural grass and 30% concentrate. The results showed that the treatment had a significant effect of p<0.05 on crude protein consumption, energy and crude protein and energy digestibility with the average value for each treatment on crude protein consumption (g/h/d) R0 23.37±2.76, R1 48 .92±6.25, R2 49.82±6.64, R3 49.96±7.10, Energy Consumption (kcal/h/d) R0 944.73±111.42, R1 1555.28±201, 78, R2 1582.51±220.04, R3 1594.11±236.58, Crude Protein Digestibility (%) R0 53.04±2.07, R1 65.92±2.30, R2 68.74±2 .89, R3 72.80±5.17, Energy Digestibility (%) R0 67.66±2.64, R1 75.60±3.99, R2 76.23±2.02, R3 76.32±3.58. So it was concluded that supplementation of trace minerals and nuclotides in concentrate feed had an effect on increasing crude protein consumption, energy, crude protein digestibility and energy in late pregnant goats.

Effects of Katuk Leaf (Sauropus androgynus L. Merr) Meal Supplementation on Physiological and Hematological Status of Peranakan Etawah Goats

The study aimed to determine the effect of supplementing katuk leaf meal in concentrate on physiological and haematological status of Etawah grade goats. The research took place at the Goat Breeding and Forage Production Installation Sumlili Village, West Kupang district of  Kupang Regency, from March to August 2024. The materials used were 12 heifers of Peranakan Etawah (PE) goats with body weight of 21.5 – 25.3kg, mean 23.4 ± 1.85kg; rations were forage (lamtoro) and concentrate. The study used a 4 x 3 completely randomised design (CRD), with four treatments tried, namely: P0 = farmer’s pattern ration of lamtoro leaves + 300g concentrate (70% fine bran: 30% ground yellow corn) without katuk leaf meal; P1 = P0 + 5% DM forage; P2: P0 + 10% DM forage; P3= P0 + 15% DM forage. The observed variables were respiration rate, pulsus rate, rectal temperature, haemoglobin content, erythrocyte count, erythrocyte and haematocrit numbers. Data were analysed according to the variance analysis procedure. The results of statistical tests showed that the treatment had no significant effect (P>0.05) on all variables observed. The average results obtained were respiration rate 63.5 beats/minute; pulsus rate 81.08 beats/minute, rectal temperature 38.16°C, haemoglobin level 10.3 g/dL; erythrocyte count 11.12 x106/mm3; leucocytes 10.3 x 103/mm3 and haematocrit number 31.0%.  It was concluded that supplementation of katuk leaf meal in concentrate did not interfere with metabolism in PE heifers under conditions with indications of physiological and haematological status within normal ranges.
