Abstract
The aim of this study was to determine the sperm fertility rate by embryo production in vivo and in vitro in South African bulls and further compare the embryo quality developed from different oocyte recovery methods. A total of 15 frozen semen straws (5 Bonsmara; 5 Nguni; 5 Boran) were thawed and evaluated for sperm motility characteristics using sperm class analyzer. The fertilizing ability of frozen–thawed semen was assessed by performing AI and in vitro fertilization. For AI, 6 cows were superovulated and inseminated with frozen–thawed semen followed by flushing on Day 7 post-insemination and then evaluated for embryo developmental stages. For IVF, oocytes were retrieved using two recovery methods namely ovum pick-up (OPU) and ovary aspiration. A total of 383 (106, OPU; 277, ovary aspiration) oocytes were matured in M199 + 10% fetal bovine serum (FBS) maturation medium at 38.5°C for 24h. Oocytes were washed in Bracket and Oliphant’s fertilization medium, co-incubated with frozen–thawed (Boran) semen at 38.5°C for 6 h, and then cultured in SOF-BSA medium, incubated at 38.5°C, 5% CO2 for 7 days, and further evaluated for embryo development. Data were analysed by ANOVA. Total sperm motility was >70% in all breeds. Boran had a significantly (P < 0.05) higher total post-thaw sperm motility (93.2 ± 3.6) compared with Nguni (75.1 ± 4.2) and Bonsmara (80.7 ± 6.9). Furthermore, Boran had higher (P < 0.05) progressive motility (39.7 ± 3.4) and rapid motility (36.1 ± 5.9) compared with other breeds. Interestingly, Boran produced significantly (P < 0.05) higher blastocyst rate (56.34%) compared with Bonsmara (38.03%) Nguni (31.08%). Superovulation and OPU resulted in a significantly higher (P < 0.05) number of blastocysts (10.5 ± 3.3 and 10.5 ± 3.3) respectively, compared with aspiration (1.3 ± 3.3). Moreover, the OPU method yielded a significantly higher (P < 0.05) number of grade 2 blastocyst (3.0 ± 0.1) compared with aspiration (0.50 ± 0.1). However, there was no significant (P > 0.05) difference in the number of grade 1 and grade 3 blastocysts obtained when the 3 recovery methods were used. In conclusion, the Boran breed showed better a sperm fertility rate following in vivo and in vitro embryo production. The superovulation and OPU methods resulted in higher numbers and better quality blastocysts compared with aspiration.

Abstract
The prediction of sperm fertility has a great economic importance to the pig breeding industry. The objective of the study was to determine the relationship between boar sperm quality and fertility following artificial insemination (AI) under smallholder production systems. A total of 18 ejaculates were collected from 3 breeding boars using a hand-gloved technique. Aliquots of diluted semen were assessed for sperm motility using a computer aided sperm analysis before AI. Sperm viability was evaluated using Synthetic Binding CD-14 (SYBR-14+)/propidium iodide (PI–), whereas sperm morphology was evaluated using Eosin Nigrosin staining. Fluorescent microscope was used at 100× magnification to count 200 sperm per slide. The semen was extended with Beltsville Thawing Solution and contained 3 × 109 sperm/dose. A total of 73 multiparous sows were inseminated twice. Fertility was measured by conception rate, farrowing rate, litter size and number of piglets born alive following AI. Sperm quality and fertility data were analysed using one-way ANOVA. Spearman’s rank correlation was used to determine the relationship between sperm quality and fertility traits. The mean values for total sperm motility ranged from 93.5 to 96.8%. Progressive and rapid sperm motility differed significantly (P < 0.05) among the boars. However, no significant differences were found for sperm velocity traits. The mean values for morphologically normal sperm ranged from 47.8 to 60.9% and live sperm ranged from 71.8 to 77.2%, but did not differ significantly among the boars (P > 0.05). Conception rate from different boars varied (P < 0.05) from 63.6 to 93.3%. Of all fertility traits studied, conception rate was significantly related to total sperm motility rate (r = 0.34, P < 0.0029), progressive motility (r = 0.29, P < 0.0141) and rapid motility (r = 0.34, P < 0.0032), although relatively low. There was a low positive relationship between morphologically normal sperm and fertility traits (P > 0.05). In conclusion, total, progressive, and rapid sperm motility rate were the only sperm traits significantly related to conception rate. Conversely, litter size and number born alive were not correlated with sperm motility, viability, or morphology traits.

Abstract
The growth, development and functioning of legumes are often significantly affected by exposure to tropospheric ozone (O3) pollution. However, surprisingly little is known about how leguminous Nitrogen (N) fixation responds to ozone, with a scarcity of studies addressing this question in detail. In the last decade, ozone impacts on N-fixation in soybean, cowpea, mung bean, peanut and clover have been shown for concentrations which are now commonly recorded in ambient air or are likely to occur in the near future. We provide a synthesis of the existing literature addressing this issue, and also explore the effects that may occur on an agroecosystem scale by predicting reductions in Trifolium (clovers) root nodule biomass in United Kingdom (UK) pasture based on ozone concentration data for a "high" (2006) and "average" ozone year (2008). Median 8% and 5% reductions in clover root nodule biomass in pasture across the UK were predicted for 2006 and 2008 respectively. Seasonal exposure to elevated ozone, or short-term acute concentrations >100 ppb, are sufficient to reduce N-fixation and/or impact nodulation, in a range of globally-important legumes. However, an increasing global burden of CO2, the use of artificial fertiliser, and reactive N-pollution may partially mitigate impacts of ozone on N-fixation.
