“…According to the research, the farmers' albumin condition remained in the normal range, so there was no change after maintenance. [10] the average albumin concentration in cattle was 3.2 g/dl. Increased serum albumin concentration can be associated with cattle oocyte quality and viability [11].…”

Nutrient overload, deficiency, or imbalance are fundamental issues that frequently arises in breeder cows. Malnutrition in cattle can cause delayed puberty, an increased risk of pregnancy failure, and infertility. This study aimed to determine the effect of nutrient improvement and mineral premix supplementation on body weight, average daily gain, and blood metabolite profile of repeat breeder cattle. Sixteen Simmental Cross cattle aged 4 to 5 years (calved at least once) with an average S/C of 5 and an average body weight of 400 kg were used. The feed provided was forage, Profeed® concentrate, High Quality Feed Supplement (HQFS) and mineral premix. This study was initiated by selecting repeat breeder cattle of smallholder farmers. The selected cattle were reared for three months in the research cage with a predetermined feed for each group. During the research period, four weighings were carried out to determine the body weight of the cattle. Blood samples were taken for testing of the blood metabolite profile; at the beginning and end of the study. The collected samples were then analyzed in the laboratory, and the resulting data was analyzed for variance using the independent-t-test and paired t-test. The results showed that the addition of 0.5% mineral premix had no significant effect (P > 0.05) on body weight gain. In the blood metabolite profile, the improvement in nutrition had a significant effect (P<0.05) on glucose levels (H-0 and H-71). It can be concluded that the supplementation of 0.5% mineral premix has no effect on body weight and blood metabolite profiles. Repeat breeder cattle on smallholder farmers have low glucose levels, so improving nutrition (quality and quantity) is a matter of concern to support pregnancy.

“…Thiols are known to be efficient antioxidants, and their high concentrations are indicative of low levels of OS [ 49 , 50 ]. The increased oxidation of thiol groups due to increased ROS can cause a general alteration of the thiol–disulfide status, with the consequent reduction of the total antioxidant capacity of SP [ 22 ].…”

This study aimed at evaluating the relationship between biomarkers of oxidative stress (OS) in seminal plasma and sperm motility in bulls before and after cryopreservation. Three ejaculates per bull were collected from 20 young bulls. Each ejaculate was analyzed for motility before and after cryopreservation (by CASA), and the SP concentration of Advanced Oxidation Protein Products (AOPP), thiols, and carbonyl groups (CT) were examined. Then, based on their motility, the ejaculates were grouped into: high motility fresh (HMF), low motility fresh (LMF), high motility thawed (HMT), and low motility thawed (LMT) groups. Higher AOPP and thiol concentrations on SP were related (p < 0.05) to the higher LIN and BCF and lower ALH of fresh semen. In addition, AOPP and thiols were significantly higher in HMF than LMF. As a confirmation of this, the Receiver Operating Characteristic (ROC) curve analysis showed that AOPP and thiol concentrations in SP were able to discriminate between HMF and LMF ejaculates (Area Under the Curve of 71.67% and 72.04%, respectively). These observations give an alternative perspective on the relationship between sperm motility and the OS parameters of SP, which need further investigations.

Species Differences in Tryptophan Metabolism and Disposition

Major species differences in tryptophan (Trp) metabolism and disposition exist with important physiological, functional and toxicity implications. Unlike mammalian and other species in which plasma Trp exists largely bound to albumin, teleosts and other aquatic species possess little or no albumin, such that Trp entry into their tissues is not hampered, neither is that of environmental chemicals and toxins, hence the need for strict measures to safeguard their aquatic environments. In species sensitive to toxicity of excess Trp, hepatic Trp 2,3-dioxygenase (TDO) lacks the free apoenzyme and its glucocorticoid induction mechanism. These species, which are largely herbivorous, however, dispose of Trp more rapidly and their TDO is activated by smaller doses of Trp than Trp-tolerant species. In general, sensitive species may possess a higher indoleamine 2,3-dioxygenase (IDO) activity which equips them to resist immune insults up to a point. Of the enzymes of the kynurenine pathway beyond TDO and IDO, 2-amino-3-carboxymuconic acid-6-semialdehyde decarboxylase (ACMSD) determines the extent of progress of the pathway towards NAD+ synthesis and its activity varies across species, with the domestic cat ( Felis catus) being the leading species possessing the highest activity, hence its inability to utilise Trp for NAD+ synthesis. The paucity of current knowledge of Trp metabolism and disposition in wild carnivores, invertebrates and many other animal species described here underscores the need for further studies of the physiology of these species and its interaction with Trp metabolism.
