Báez F, López Darriulat R, Rodríguez-Osorio N, Viñoles C. Effect of season on germinal vesicle stage, quality, and subsequent in vitro developmental competence in bovine cumulus-oocyte complexes. J Therm Biol 2022; 103:103171. [PMID: 35027190 DOI: 10.1016/j.jtherbio.2021.103171] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 12/11/2021] [Accepted: 12/16/2021] [Indexed: 12/14/2022]
Abstract
Although the reproductive performance of grazing cattle is lower in summer compared to winter, the effect of season on oocyte developmental competence has not been thoroughly examined. We measured the effect of season on oocyte chromatin compaction, cumulus cell quality, and embryonic development after in vitro fertilization. Cumulus oocytes-complexes (COCs) were collected from abattoir cows' ovaries during the winter and summer months. First, we evaluated the degree of chromatin compaction in germinal vesicle (GV) oocytes (GV1 through GV3), which is associated with different degrees of developmental competence. Then, we determined the apoptotic index in cumulus cells from immature and in vitro matured COCs. Finally, in vitro matured oocytes were fertilized to determine blastocyst rate and embryo quality. During the summer months, we observed a significantly lower proportion of oocytes reaching the GV3 stage and higher levels of DNA fragmentation in cumulus cell. As a result, blastocyst yield and quality were reduced during the summer months. In conclusion, summer negatively affected oocyte GV stage progression, cumulus cell quality, and embryo development. Increased cumulus cell DNA fragmentation during summer, may partially explain the reduced oocyte maturation capacity, considering the relevance of cumulus-oocyte communication during this stage.

Strategic control of cattle co-parasitized by tick, fly and gastrointestinal nematodes: Is it better to use ecto + endoparasiticide or just endectocide formulations? Vet Parasitol 2021; 301:109622. [PMID: 34861577 DOI: 10.1016/j.vetpar.2021.109622] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 10/26/2021] [Accepted: 11/19/2021] [Indexed: 12/19/2022]
Abstract
Ticks, flies, and gastrointestinal helminths (GINs) significantly affect cattle productivity; thus, ectoparasiticide, endoparasiticide, and endectocide drugs have commonly been used for their control. The study aimed to compare the technical (parasites counts), productive, and financial effects of a treatment protocol comprising ecto- + endoparasiticides formulations (T01: fluazuron 2.5 mg/kg + fipronil 1.25 mg/kg and fenbendazole 5 mg/kg; n = 15) to a treatment with one formulation of endectocide (T02: ivermectin 450 μg/kg + abamectin 250 μg/kg; n = 15) over 308 days under field conditions in crossbred cattle co-parasitized by Rhipicephalus microplus, Haematobia irritans, and GINs. Bovine weight gain and return on investment (ROI) were also evaluated. Bovines from T01 received four treatments against the cattle tick and two against two GINs. For T02, four treatments were performed. Animals from T01 gained 15.4 kg more than T02 and provided a comparative ROI of 15.8. In cattle co-parasitized with R. microplus, H. irritans, and GINs, the treatment protocol used in this study with ecto- + endoparasiticidal action formulations showed better technical results regarding parasite counts and productive and financial data than the strategic treatment protocol using only an endectocide formulation.

Abstract
Ruminant livestock are raised under diverse cultural and environmental production systems around the globe. Ruminant livestock can play a critical role in food security by supplying high-quality, nutrient-dense food with little or no competition for arable land while simultaneously improving soil health through vital returns of organic matter. However, in the context of climate change and limited land resources, the role of ruminant-based systems is uncertain because of their reputed low efficiency of feed conversion (kilogram of feed required per kilogram of product) and the production of methane as a by-product of enteric fermentation. A growing human population will demand more animal protein, which will put greater pressure on the Earth's planetary boundaries and contribute further to climate change. Therefore, livestock production globally faces the dual challenges of mitigating emissions and adapting to a changing climate. This requires research-led animal and plant breeding and feeding strategies to optimise ruminant systems. This study collated information from a global network of research farms reflecting a variety of ruminant production systems in diverse regions of the globe. Using this information, key changes in the genetic and nutritional approaches relevant to each system were drawn that, if implemented, would help shape more sustainable future ruminant livestock systems.

Trop Anim Health Prod 2020; 52:1733-1738.

Abstract
The influence of shade in the silvopastoral system on the performance and degree of parasitism by endo- and ectoparasites in Angus x Nellore heifers was assessed. The experiment was conducted with 72 heifers, with an initial mean weight of 276 ± 5.67 kg and 9 months of age, in a total area of 25 ha, divided into 12 paddocks, with three treatments and four replicates. The experimental design was a randomized complete block design, to evaluate the conventional grazing system (CGS) without shade and silvopastoral systems with simple line (SPS1) or triple lines (SPS3) of eucalyptus. The evaluations were carried out every 28 days, from June 2017 to April 2018. During the trial, the number of eggs per gram of feces (EPG) presented a gradual increase in the three systems. Differences (P < 0.05) in the variables analyzed were recorded only in two occasions: the CGS group EPG mean ± standard error (1269 ± 105) was higher than the SPS1 group mean (402 ± 129 EPG) in March, and tick average of the CGS group (13 ± 2.7) was lower than the SPS3 (32 ± 5.3) in October. There were no significant differences (P ≥ 0.05) between groups in relation to horn fly counts, the numbers of infective nematode larvae on pasture, hematological variables, and weight gain. It was concluded that in comparison with the CGS system, the shading in the SPS1 and SPS3 systems did not have any major influence on the degree of parasitism or in the performance of the heifers.
