ABSTRACT.
We studied whether the long-term effects of nutrition on ram reproductive potential are mediated by changes in the expression and distribution of leptin receptor (Ob-Rb) in the testes. Thirty-two young Merino rams were allocated to a 2 × 2 factorial design, with either natural (NP) or improved pastures (IP), with (+S) or without (?S) supplementation. After 14 weeks of treatment, a blood sample was taken to measure leptin concentrations and rams were castrated. The weights of testicles (TW) and epididymides (EW) were recorded before tissue sampling for the detection of Ob-Rb expression by immunohistochemistry. TW was positively affected by the interaction IP × S, but not EW and bodyweight (BW), which were affected either by IP or S (P < 0.05). TW and EW were greatest (g) in IP+S rams (290.6 ± 40.1 and 57.6 ± 2.3), followed by IP?S (284.6 ± 61.4 and 52.5 ± 2.3), NP+S (282.6 ± 37.9 and 55.8 ± 2.3), and NP?S rams (208.5 ± 48.7 and 44.4 ± 2.3; P < 0.01). Expression of Ob-Rb was observed in the cytoplasm of Leydig cells, without any effect of treatments on the percentage of positive Leydig cells or on staining-intensity score. The serum leptin concentrations were similar among groups. The absolute volume of the seminiferous epithelium (mL) was affected by IP and S, as well as by their interaction (IP?S: 179.7 ± 13.1, IP+S; 174.9 ± 9.0; NP+S: 178.0 ± 10.2; NP?S: 120.8 ± 9.8; P < 0.05). We conclude that, under the conditions of the present study, the long-term improvement of nutrition promoted histological changes of increased spermatogenesis of Merino rams, but was not related to changes in the expression of the Ob-Rb receptor in the Leydig cell cytoplasm.

ABSTRACT.- Ensuring the sustainability and circularity of mixed crop-ruminant livestock systems is essential if they are to deliver on the enhancement of long-term productivity and profitability with a smaller footprint. The objectives of this study were to select indicators in the environmental, economic and social dimensions of sustainability of crop-livestock systems, to assess if these indicators are relevant in the operational schedule of farmers, and to score the indicators in these farm systems. The scoring system was based on relevance to farmers, data availability, frequency of use, and policy. The study was successful in the assemblage of a suite of indicators comprising three dimensions of sustainability and the development of criteria to assess the usefulness of these indicators in crop-ruminant livestock systems in distinct agro-climatic regions across the globe. Except for ammonia emissions, indicators within the Emissions to air theme obtained high scores, as expected from mixed crop-ruminant systems in countries transitioning towards low emission production systems. Despite the inherent association between nutrient losses and water quality, the sum of scores was numerically greater for the former, attributed to a mix of economic and policy incentives. The sum of indicator scores within the Profitability theme (farm net income, expenditure and revenue) received the highest scores in the economic dimension. The Workforce theme (diversity, education, succession) stood out within the social dimension, reflecting the need for an engaged labor force that requires knowledge and skills in both crop and livestock husbandry. The development of surveys with farmers/stakeholders to assess the relevance of farm-scale indicators and tools is important to support direct actions and policies in support of sustainable mixed crop-ruminant livestock farm systems. © 2024 Elsevier B.V.
