Background: Beta-carotene (BETA) is a precursor of retinol (Vitamin A) and positively influenced on reproductive efficiency in cows. The aim of the study was to determine the effect of orally supplementation of beta-carotene on plasma carotene content and fertility rate of lactating crossbred Sahiwal cows. Methods: Twenty-four disease-free lactating crossbred Sahiwal cows with a close date of calving were randomly divided into two homogeneous groups for Control group (CONT; n = 12) and Beta-carotene group: 500 mg/cow/d (BETA; n = 12) from 7 days post partum (dpp) until 105 dpp thereafter on concentrations of beta-carotene and selected protein and energy parameters in plasma were determined. In addition, effects on fertility rate were studied. Result: Beta-carotene concentrations increased in plasma of beta-carotene (BETA-group) supplemented cows compared to control (CONT-group) cows (p<0.001). In BETA-group cows, urea concentration in blood plasma decreased significantly compared to cows of CONT-group (p<0.001) but did not differ in total protein, albumin, glucose and total cholesterol content in cows of both groups. Occurrence of first post partum estrus decreased (p<0.001) in beta-carotene (BETA-group: 74 dpp) cows compared to control (CONTgroup: 81 dpp) cows. In this study, it was observed that the overall conception rate was higher (p<0.001) in BETA-group: 83.33% (cows pregnant: 10/12) and lesser in the CONT-group: 50.00% (cows pregnant: 6/12). The results of this study indicated that oral supplementation with beta-carotene increased the concentration of beta-carotene and decreased the concentration of urea in plasma and cows with higher blood plasma beta-carotene content improved fertility over cows with lower blood plasma beta-carotene content. © 2021 Agricultural Research Communication Centre.

Environmental waste regarding soft foreign body (plastic) – a threat to livestock health

Uncontrolled waste disposal, which includes polymers materials, wood, paper, nails, rubber, and rope, has a variety of harmful repercussions for the environment and animal health. Ruminal impaction, indigestion, repeated tympany, and a wide range of other undesirable health implications can result from the accumulation of indigestible plastic foreign bodies in the rumen of ruminants. Ruminal impaction occurs when ruminants are fed indigestible plastic waste items without proper supervision. Stray animals living in metropolitan areas of developing countries are the most likely to contract the disease. Toxins from plastic waste are released into the rumen fluid, eventually entering the food chain through milk and meat products. Human health is jeopardised by their use, causing food poisoning and severe health issues. Plastic-related ruminal impaction in ruminants can only be diagnosed and treated with exploratory rumenotomy. Good animal husbandry practices and proper disposal of plastic trash can help to eliminate this issue. Ruminal impaction in ruminants induced by plastic materials will be discussed in detail in the following sections: epidemiology, pathophysiology, diagnostics, therapy, prevention, and management. The current chapter examines the epidemiology, pathophysiology, diagnosis, treatment, prevention, and management of ruminal impaction in ruminants caused by plastic materials. © 2023 Elsevier Inc.
