“…Furthermore, Se is necessarily required to maintain many metabolic functions and the growth performance of ruminants. Being an antioxidant element, it acts as a selenoprotein for the principal enzymes of the antioxidant defense mechanism, including glutathione peroxidase (GSH-Px) and thioredoxin reductase (TrxR) (65). More than that, Fe, Zn, Cu, and Mn are structural components of SODs, which are subdivided into four groups on the basis of their metal cofactors, including Fe-SOD, Cu/Zn-SOD, and Mn-SOD (66).…”

IntroductionThe rutting period imposes a stressful condition on male camels, which results in elevated serum cortisol levels and alterations in their sexual behavior. Therefore, the current work was carried out to investigate the effect of mineral-vitamin premix supplementation on behavior, reproductive performance, hormones, serum oxidative stress profile, and other serum biochemical parameters of Camelus dromedarius during the breeding season.MethodsFourteen mature, fertile male Camelus dromedarius were divided into two groups, a control group (n = 7) and a mineral-vitamin premix group (n = 7). The present study lasted for 95 days during the rutting period (1st February to 5th May). Each camel in the premix group received a daily diet of 50 g of mineral-vitamin premix throughout the whole rutting period, during which the frequencies and durations of the following behaviors: maintenance, posture, aggressiveness, and sexual activity were collected every 20 min. At the end of the study, blood samples were collected.ResultsResults revealed that the premix group showed higher (P < 0.05) maintenance (feeding and rumination), standing, and overall sexual desire-related behavior frequency, besides more times (P < 0.001) for rumination, standing, walking, and lying while showing lower (P < 0.001) frequencies of overall aggressive behaviors than the control group. The serum concentration of malondialdehyde, nitric oxide, cortisol, blood glucose, and urea evidenced a significant decrease in the premix group compared with the control one, while significantly elevated levels of reduced glutathione, testosterone, total antioxidant capacity, triiodothyronine, and thyroxin, total protein, albumin, globulin, calcium, phosphorus, potassium, and magnesium were recorded in the premix group in comparison with the control.ConclusionIt could be concluded that daily dietary supplementation of 50 g of mineral-vitamin premix to male camels during the breeding season is necessary to overcome the oxidative stress and serum cortisol concentration with a subsequent decrease in aggressive behavior and improvement to testosterone level in blood, body condition score and body weight gain.

Selenium is an essential micronutrient for ruminants, which participates in the optimal functioning of proteins and enzymes that can combat oxidative stress in the body; however, its toxicity is documented in different species. The objective of this work was to describe macroscopic and microscopic lesions in lambs intoxicated with selenium administered through intraruminal boluses. The main lesions at necropsy were pulmonary oedema; the myocardial surface presented multifocal pale areas; the thyroid and thymus glands were decreased in size, and areas of necrosis, haemorrhage and hyperkeratosis were observed in the reticulum and rumen. At the microscopic level, congestion, haemorrhage, oedema and hyaline membranes were observed in the lung; hepatic congestion, haemorrhage, degeneration and necrosis; degeneration and necrosis of the reticulum mucosa, as well as areas of hyperplasia and hyperkeratosis; myocardial degeneration, necrosis and fibrosis; congestion, haemorrhage, degeneration and renal tubular necrosis; thyroid follicular atrophy and thymic cortical atrophy. This study evidenced the main lesions related to selenium poisoning in lambs supplemented with the mineral through intraruminal boluses.

Milk production is a key component of the agriculture sector in the tropics and subtropics, contributing 47.32% to global milk production. This study aimed to quantify milk production and composition (fat and protein) in warm-climate regions located between 30 degrees north and south of the equator. A meta-analysis was conducted using the standardized mean (SM) for milk production, fat percentage, and protein percentage, all adjusted for dry matter intake (DMI), focusing on lactating ruminants. A total of 42, 11, 15, and 16 research papers were selected for cows, buffalo, sheep, and goats, respectively, encompassing 2421 animal records from experiments published between 1992 and 2024. The SM for milk production was 10.38, 9.77, 0.79, and 1.13 kg/day/animal for cows, buffalo, sheep, and goats, respectively. Due to the significant variance between different cow breeds, the study divided the cows into three main groups based on breed type crossbreds, foreign, and local breeds. The SM for milk production per animal was 11.49 kg/day for crossbreds, 22.95 kg/day for foreign breeds, and 7.13 kg/day for local breeds. The effect of DMI on the SM of milk production for cows, sheep, and goats was highly significant. For milk fat, the SM was 3.95, 6.64, 4.70, and 3.56% for cows, buffalo, sheep, and goats, respectively. Regarding milk protein, the SM was 3.36, 3.91, 4.34, and 3.45% for cows, buffalo, sheep, and goats, respectively. The results of this meta-analysis highlight that warm-climate regions are significant contributors to global dairy production. Furthermore, improving ruminant milk production and quality in hot climates need further efforts.
