Comparison various level ascorbic acid and lycopene additions in semen diluent enhanced sperm quality of Sapudi ram.

The primary cause of sperm quality decline during the freeze-thaw pathway is the peroxidation hazard caused by reactive oxygen species produced by the biological molecules of sperm. Ascorbic acid (Vitamin C) and lycopene are two potent antioxidants that operate to prevent oxidation processes. This study aimed to analyse the effects of ascorbic acid and lycopene on the motility, viability, abnormality and plasma membrane integrity of post-thawed Sapudi rams.

Population diversity, admixture, and demographic trend of the Sumba Ongole cattle based on genomic data.

Objective: Sumba Ongole (SO) cattle are valuable breed due to their important role in the development of Indonesian cattle. Despite rapid advances in molecular technology, no genomic studies on SO cattle have been conducted to date. The aim of this study is to provide genomic profile related to the population diversity, admixture, and demographic trends of SO cattle.

Effect of short time precise dietary energy-protein in reproductive parameters of local crossbred dairy goats.

Objective: This study aimed to establish and focus on the implications of precise energy and protein levels on reproductive performance. This study based on field facts showed that excessive feed intake, especially protein intake, to increase productivity will lead to some decreased reproductive efficiency through disruption of reproductive hormonal compound biosynthesis or increasing blood urea nitrogen (BUN), which has rarely been studied.

Materials And Methods: Healthy and mature Saanen crossbred goats raised by traditional farmers (2-4 years old; ± 45 kg) were divided into three experimental groups [T0 = basal feed according to the feed provided by farmers, T1 = protein and energy balanced feed according to National Research Council (NRC) (±5%), T2 = feed >20% excess protein, and excess energy from NRC] ( = 75).

Detection of DNA Damage in Frozen Bovine Semen Using Eosin Staining.

<b>Background and Objective:</b> Early detection of DNA defects in spermatozoa is vital because genetic abnormalities are associated with infertility and miscarriage. Eosin is an acidic stain with negatively charged chromatolytic components also found in the cytoplasm of spermatozoa. This study aimed to observe the effectiveness of eosin staining in detecting spermatozoa DNA deterioration.

Effects of body condition score and estrus phase on blood metabolites and steroid hormones in Saanen goats in the tropics.

Background And Aim: Body condition scores (BCSs) assessment can be a potential management tool for the improvement of animal performance. The study investigated whether blood metabolic (protein, glucose, blood urea nitrogen, and cholesterol) and steroid hormonal (progesterone, estrogen, and cortisol) parameters are affected by the BCS and estrous status in Saanen goat.

Materials And Methods: Blood samples were collected from three groups of mature, dry, and non-pregnant female goats with different BCSs: 2-2.

Estrus Detection Through Vaginal pH in Saanen Etawah Crossbreed Goats.

Background And Objective: In goats, weak estrus behavior is potentially caused by a decline in reproductive efficiency. In the present study, aim was to measure the vaginal pH to determine the accuracy of lust detection in Saanen Etawah crossbreed goats.

Materials And Methods: Thirteen Saanen Etawah crossbred does (Capra hircus) with body condition score of 2-3 were used.
